A couple summer’s back we had the Animas River turn yellow because of materials stored on the edge of the river. A couple years before that, coal ash and the Charleston spill. Now the “red” river (but at in Russia)….So maybe legislators can help us understand why continuing to store this stuff on the edge of water supplies is ok? Or why we shouldn’t put a bunch of money toward removing this material so water supplies and ecosystem are less at risk?
The reliability of the assets within the area of interest starts with the design process in the asset management plan. Decision-making dictates how the assets will be maintained and effective means to assure the maximum return on investments. Through condition assessment, the probability of failure can be estimated. Assets can also fail due to a growing area that may contribute to exceeding its maximum capacity. Operation and maintenance of the assets are important in reassuring a longer life span as well as getting the most out of the money to be spent. Prioritizing the assets by a defined system will allow for the community to see what areas are most susceptible to vulnerability/failure, which assets need the most attention due to their condition, and where the critical assets are located in relation to major public areas (hospitals, schools, etc.) with a high population.
So what happens when conditions change? Let’s say sea levels are rising and your land is low. What would the potential costs be to address this? Better yet, what happens if it rains? We looked at one south Florida community and the flood stage for each based on 3 storm events: the 1:10 used by FDOT (Assumes 2.75 inches in 24 hours), the Florida Building Code event that includes a 5 in in one hour event (7 in in 24 hrs), and the 3 day 25 year event (9.5-11 inches).
Of no surprise is that the flooding increases as rainfall increases. Subsequent runs assumed revisions based on sea level rise. The current condition, 1, 2 and 3 ft sea level rise scenarios were run at the 99 percentile groundwater and tidal dates and levels. Tables 2-5 depict the flood stage results for each scenarios. The final task was designed to involve the development of scenarios whereby a toolbox options are utilized to address flooding in the community. Scenarios were to be developed to identify vulnerabilities and cost effectiveness as discussed previously.
The modeling results were then evaluated based of the accompanying infrastructure that is typically associated with same. A summary of the timelines and expected risk reductions were noted in the tables associated with storm and SLR scenarios. This task was to create the costs for the recommended improvements and a schedule for upgrading infrastructure will be developed in conjunction with staff. Two issues arise. First, the community needs to define which event they are planning to address and the timelines as the costs vary form an initial need of $30 million to over $300 million long-term. Figure 1 shows how these costs rise with respect to time. The long-term needs of $5 million per 100 acres matches with a prior effort in Palm Beach County.
Figure 1 Summary of Costs over the 3 ft of potential sea level Rise by 2011, under the 3 storm planning concepts.
How many utilities have a 3D map of their infrastructure? Not many I bet. But FAU does. Here is a recently completed project we did with students and the Facilities Maintenance staff at FAU (costs involved). They needed better mapping and will tie this to their work order system. It was an excellent opportunity for two groups within one organization that otherwise seem to have little in common wot work toward a great project. We will be inputting this data into an online asset management system this summer along with some data for Dania Beach so they will have a portion of their utility system in 3D also. This is part of a tiny project we did for their downtown area.
GIS is a powerful tool and one utilities should embrace wholeheartedly. There is so much more than mapping to do. Data gathering in critical, but with Leica and Trimble units, a lot of data can be gathered easily. LiDAR can be expensive, but the value is tremendous. You can see that the FAU system is laid on a 3D LiDAR topographic map (6 in vertical accuracy). Asset condition assessments were also done concurrently, which adds a lot of information to the system (all assets were also photographed and linked). Drawing files can be downloaded and extruded from 2D to 3D. Engineers know GIS or can learn it, which makes a fully expanded GIS system for the utility easy to derive if the time is spent. This is a valuable tool when linked to work orders and asset management programs.
So is your utility in 3D?
Here is an example of getting to a condition assessment with limited data using power point slides. Note that where there are categorical variables (type of pipe for example), these need to be converted to separate yes/no questions as mixing. Categorical and numerical variable do not provide appropriate comparisons = hence the need to alter. Take a look – but the concept is to predict how well this model explains the break history on this distribution system. Call me and we can try it on yours….
Step 1 Create a table of assets (this is a small piece of a much larger table).
Step 2 Create columns for the variables for which you have data (age, material, soil type, groundwater level, depth, traffic, trees, etc.)
|Asset||breaks in 10 year||Dia||Age||soil||traffic||Trees||depth||pressure||material||Filed estimate of cond.ition|
Step 3 All variables should be numeric. So descriptive variables like pipe material need to be converted to binary form – i.e. create a column for each material and insert a 1 or 0 for “yes” and “no.”
Step 4 Run Linear regression to determine factors associated with each and the amount of influence that each exerts. The result will give you a series of coefficients:
Step 5 – Use this to predict where your breaks will likely be in the next 5-10 years.
The process is time consuming but provides useful information on the system. It needs to be kept up as things change, but exact data is not really needed. And none of this requires destructive testing. Not bad for having no information.
An asset management program should be developed accordingly to the client’s goals and objectives. It consists of determining the selected area of study, type of system and the quality of data used for evaluation. Before a condition assessment can be determined, an inventory of assets needs to be established – maps, etc. are helpful. So now you have a map of your water and sewer system and you want to develop a useful system for asset management. Depending on the accuracy wanted, the data can be gathered in many ways ranging from onsite field investigation which could take a lot of time, to using existing maps, using maps while verifying the structures using aerial photography and video, or field investigations. But most local governments still lack data. You cannot dig up pipe, or do a lot of destructive testing on buried infrastructure. So what to do?
The reality is that you have a lot more data than one thinks. For one thing, most utilities have a pretty good idea about the pipe materials. Worker memory can be very useful, even if not completely accurate. In most cases the depth of pipe is fairly similar – the deviations may be known. Soil conditions may be useful – there is an indication that that aggressive soil causes more corrosion in ductile iron pipe, and most soil information is readily available. Likewise tree roots will wrap around water and sewer pipes, so their presence is detrimental. Trees are easily noted from aerials. Likewise road with truck traffic create more vibrations on roads, causing rocks to move toward the pipe and joints to flex. So with a little research there are at least 5 variables known. If the break history or sewer pipe condition is known, the impact of these factors can be developed via a linear regression program. That can then be used as a predictive tool to help identify assets that are mostly likely to become a problem. We are working on such an example now, but suspect that it will be slightly different for each utility. Also, in smaller communities, many variables (ductile iron pipe, pvc pipe, soil condition…) may be so similar that differentiating would be unproductive. That also remains to be seen, which brings up another possible variable- the field perception – what do the field crews recall about breaks? Are there work orders? If so do they contain the data needed to piece together missing variables that would be useful to add to the puzzle?
After all we want to avoid this before it happens….
I have a question – what was the impact of the 2008 economic crisis on water and sewer infrastructure funding? I have a hypothesis – the amount of monies transferred to non-water and sewer operations increased. Is the hypothesis true?
The next question to answer is that if transfer monies increased, did they decrease once property values started to come back? My hypothesis is no.
Finally what impact does this have on water and sewer infrastructure going forward? I suspect that the answer is that we underfund infrastructure or justify the lack of funding through actuarial means (I actually had a utility director tell me that his pipes were designed to last 250 years. Seriously. Of course that is nonsense, but it is a means to keep your need for replacement funding down).
I have a student and we are working on these issues now. We are going to gather data from several hundred utilities over the next six months, crunch 11 years of data and let’s find out. If you or your clients are interested in adding your data to the mix, please send it to me. I need 2005 -2015 expenditure info. Also some operational data like ADF, MDF, miles of pipe, customers, treatment type and CCR. We will be publishing the results. Should be interesting……
Speaking of water supply problems, welcome to Flint, Michigan. There have been a lot of coverage in the news about the troubles in Flint the last couple of months. However if you read between the lines you see two issues – first this is not new – it is several years old, going back to when the City’s water plant came back on line in May 2014. Second this was a political/financial issue not a public health issue. In fact, the political/financial goals appear to have been so overwhelming, that the public health aspects were scarcely considered. Let’s take a look at why.
Flint’s first water plant was constructed in 1917. The source was the Flint River. The second plant was constructed in 1952. Because of declining water quality in the Flint River, the city, in 1962, had plans to build a pipeline from Lake Huron to Flint, but a real estate scandal caused the city commission to abandon the pipeline project in 1964 and instead buy water from the City of Detroit (source: Lake Huron). Flint stopped treating its water in 1967, when a pipeline from Detroit was completed. The City was purchasing of almost 100 MGD. Detroit declared bankruptcy. The City of Flint was basically bankrupt. Both had appointed receivers. Both receivers were told to reduce costs (the finance/business decisions). The City of Flint has purchased water for years from Detroit as opposed to using their Flint River water plant constructed in 1952. The Flint WTP has been maintained as a backup to the DWSD system, operating approximately 20 days per year at 11 MGD.
The City of Flint joined the Karegnondi Water Authority (KWA) in 2010. The KWA consists of a group of local communities that decided to support and fund construction of a raw water pipeline to Lake Huron. The KWA was to provide the City of Flint Water Treatment Plant with source water from Lake Huron. An engineer’s report noted that a Genesee County Drain Commissioner stated that one of the main reasons for pursuing the KWA supply was the reliability of the Detroit supply given the 2003 power blackout that left Flint without water for several days. Another issue is that Flint no say in the rate increases issued to Flint by Detroit. Detroit’s bankruptcy may also have been a factor given the likelihood of increased prices. While discussion were ongoing for several years thereafter, the Detroit Free Press reported a 7-1 vote in favor of the KWA project by Flint’s elected officials in March, 2013. The actual agreement date was April 2013. The cost of the pipeline was estimated to be $272 million, with Flint’s portion estimated at $81 million.
The City of Detroit objected due to loss of revenues at a time when a receiver was trying to stabilize the city’s finances (in conjunction with the State Treasurer). In February 2013, the engineering consulting firm of Tucker, Young, Jackson, Tull, Inc. (TYJT), at the request of the State Treasurer, performed an analysis of the water supply options being considered by the City of Flint. The preliminary investigation evaluated the cost associated with the required improvements to the plant, plus the costs for annual operation and maintenance including labor, utilities, chemicals and residual management. They indicated that the pipeline cost was likely low and Flint’s obligation could be $25 million higher and that there was less redundancy in the KWA pipeline than in Detroit’s system. In 2013, the City of Detroit made a final offer to convince Flint to stay on Detroit water with certain concessions. Flint declined the final Detroit offer. Immediately after Flint declined the offer, Detroit gave Flint notice that their long-standing water agreement would terminate in twelve months, meaning that Flint’s water agreement with Detroit would end in April 2014 but construction of KWA was not expected to be completed until the end of 2016.
It should be noted that between 2011 and 2015, Flint’s finances were controlled by a series of receivers/emergency managers appointed by the Governor. Cutting costs was a major issue and clearly their directive from the Governor. Cost are the major issue addressed in the online reports about the issue. Public health was not.
An engineering firm was hired as the old Flint River plan underwent $7 million in renovations in 2014 to the filters to treat volumes of freshwater for the citizens. The project was designed to take water from the Flint River for a period of time until a Lake Huron water pipeline was completed. The City of Flint began using the Flint River as a water source in May of 2014 knowing that treatment would need to be closely watched since the Michigan Department of Environmental Quality in partnership with the U.S. Geological Survey, and the City of Flint Utilities Department conducted a source water assessment and determined the susceptibility of potential contamination as having a very high susceptibility to potential contaminant sources (take a look at this photo and see what you think).
Flows were designed for 16 MGD. Lime softening, sand filters and disinfection were in place. Everything sounded great. But it was not. Immediately, in May and August of 2014, TTHM samples violated the drinking water standards. This means two things – total organic carbon (TOC) in the water and additional chlorine being added to disinfect and probably reduce color caused by the TOC. Softening does not remove TOC. Filtration is not very effective either. High concentration usually needs granular activated carbon, ion exchange or membranes. The flint plant had none of these, so the carbon staying in the water. To address the TTHM issue, chlorine appears to have been reduced as the TTHM issue was in compliance by the next sampling event in Nov 2014. However, in the interim new violations included a total coliform and E. coli in August and September of 2014, and indication of inadequate disinfection. That means boil your water and lots of public outcry. The pH, salinity (salt) and other parameters were reported to be quite different than the Detroit water as well. A variable river system with upstream agriculture, industry and a high potential for contamination, is not nearly as easy to treat as cold lake water. These waters are very different as they City was to find. What this appears to indicate is that the chemistry profile and sampling prior to conversion and startup does not appear to have been fully performed to identify the potential for this to occur or this would have been discovered. This is now being suggested in the press.
The change in water quality and treatment created other water quality challenges that have resulted in water quality violations. Like most older northern cities, the water distribution system in almost 100 years old. As with many other municipalities at the time, all of the service lines from the cast iron water mains (with lead joints) to end users homes were constructed with lead goosenecks and copper lines. Utilities have addressed this with additive to prevent corrosion. In the early 1990s water systems were required to comply with the federal lead and copper rule. The concept was that on the first draw of water in the morning, the lead concentration should not exceed 0.015 mg/L and copper should not exceed 1.3 mg/L. Depending on the size of the utility, sampling was to be undertaken twice and a random set of hoses, with the number of samples dependent on the size of the system. The sampling was required to be performed twice, six months apart (note routine sampling has occurred since then to insure compliance). Residents were instructed on how to take the samples, and results submitted to regulatory agencies. If the system came up “hot” for either compound, the utility was required to make adjustments to the treatment process. Ideally water leaving the plant would have a slightly negative Langlier saturation index (LSI) and would tend to slightly deposit on pipes. Coupon tests could be conducted to demonstrate this actually occurred. As they age, the pipes develop a scale that helps prevent leaching. Most utilities tested various products. Detroit clearly did this and there were no problems. Flint did not.
The utility I was at was a perfect 100% non-detects the first time were tested. We had a few detections of lead and copper in samples the second time which really bothered me since the system was newer and we had limited lead in the lines. I investigated this and found that the polyphosphate had been changed because the County purchasing department found a cheaper product. I forced them to buy the old stuff, re-ran the tests and was again perfect. We instructed our purchasing department that saving a few bucks did not protect the public health, but the polyphosphate product did. Business and cost savings does not trump public health! Different waters are different, so you have to test and then stay with what works.
Now fast forward to Flint. They did not do this testing. The Flint River water was different that Detroit’s. Salinity, TOC, pH and overall quality differed. Accommodations were not made to address the problem and the state found no polyphosphates were added to protect the coatings. Veolia reported that the operations needed changes and operators needed training. Facilities were needed to address quality concerns (including granular activated carbon filter media). As a result the City appears to have sent corrosive water into the piping system, which dissolved the scale that had developed over the years, exposing raw metal, and created the leaching issue. Volunteer teams led by Virginia Tech researchers reported found that at least a quarter of Flint households have levels of lead above the federal level of 15 ppb, and as high as 13,200 ppb. Aging cast-iron pipe compounded the situation, leading to aesthetic issues including taste, odor and discoloration that result from aggressive water (brown water). Once the City started receiving violations, public interest and scrutiny of the drinking water system intensified.
The City Commission reportedly asked the receiver to switch back to Detroit water, but that request was initially rebuffed and the damage to pipes continued. Finally in October 2015, the water supply was switched back to Detroit and the City started adding additional zinc orthophosphate in December 2015 to facilitate the buildup of the phosphate scale eroded from the pipes by the Flint River water. But that means the pipes were stable, then destabilized, now destabilized again by the switch back. It will now take some time for the scale to rebuild and to lower lead levels, leaving the residents of Flint at risk because of a business/finance/political decision that had not consideration of public health impacts. And what is the ultimate fate of the KWA pipeline?
Just when things were starting to look up (?), in January 2016, a hospital in Flint reported that low levels of Legionnaires’ disease bacteria were discovered in the water system and that 10 people have died and another 77 to 85 affected. From the water system? A disinfection problem? Still TOC in the water? The lawsuits have begun but where does the problem lie? Let’s look at Walkerton Ontario for guidance in the aftermath of their 2000 incident.
First it is clear that public health was not the primary driver for the decisions. Treating water is not as simple as cost managers think. You need to understand what water quality, piping quality and stabilization you have and address the potential issues with new water sources. Membrane systems are very familiar with these challenges. Cost cannot be the driver. The Safe Drinking Water Act does not say cost is a consideration you use to make decisions. Public health is. So the initial decision-making appears to have been flawed. Cost was a Walkerton issue – cost cannot be the limiting factor when public health is at risk.
The guidance from consultants or other water managers is unclear. If the due diligence of engineers as to water quality impacts of the change in waters was not undertaken, the engineering appears to have been flawed. If the engineer recommended, and has lots of documentation saying testing should be done, but also a file full of accompanying denials from the receivers, another flawed business decision that fails the public health test. If not, I see a lawsuit coming against the consultants who failed in their duty to protect the public health, safety and welfare.
The politics is a problem. A poor community must still get water and sewer service. Consultants that can deal with rate and fee issues should be engaged to address fairness and pricing burdens. Was this done? Or was cutting costs the only goal? Unclear. The politics was a Walkerton issue.
Was the water being treated properly? Water quality testing would help identify this. Clearly there were issues with operations. Telling the state phosphates were used when they were not, appears to be an operations error. Walkerton also had operations issues as well. A major concern when public health is at risk. Veolia came to a similar conclusion.
The state has received its share of blame in the press, but do they deserve it? The question I have is what does the regulatory staff look like? Has it been reduced as the state trims its budget? Are there sufficient resources to insure oversight of water quality? The lack of provincial resources to monitor water quality was an issue in Walkerton – lack of oversight compounded local issues. That would then involve the Governor and Legislature. Politics at work. Likewise was there pressure applied to make certain decisions? If so, politics before public heath – a deadly combination.
So many confounding problems, but what is clear is that Flint is an example of why public utilities should be operated with public health at the forefront, not cost or politics. Neither cost of politics protect the public health. While we all need finances to pay for our needs, in a utility, money supports the operations, not controls it. We seems to have that backward. Private entities look sat controlling costs. Public agencies should look at public service first; cost is down the list. We need the operations folks to get the funds needed to protect the public health. And then we need to get the politicians to work with the staff to achieve their needs, not limit resources to cut costs for political gain. Ask the people in Flint.
So is Flint the next Walkerton? Will there be a similar investigation by outside unconnected people? Will the blame be parsed out? Is there a reasonable plan for the future? The answers to these questions would provide utilities with a lot of lessons learned and guidance going forward and maybe reset the way we operate our utilities. Happy to be a part of it if so!
In the last blog we talked about a side issue: ecosystems, bison, wolves, coyotes and the Everglades, which seem very distant form our day-to-day water jobs, but really are not. So let’s ask another, even more relevant issue that strikes close to home. Why is it that it is a good idea to store coal ash, mine tailings, untreated mine waste, garbage, and other materials next to rivers? We see this over and over again, so someone must think this is brilliant. It cost Duke Energy $100 million for the 39,000 tons of coal ash and 24 MG of wastewater spilled into the Dan River near Eden NC in 2014. In West Virginia, Patriot Coal spilled 100,000 gallons of coal slurry into Fields Creek in 2014, blackening the creek and impacting thousands of water supply intakes. Fines to come. Being a banner year for spills, again in West Virginia, methylcyclohexamethanol was released from a Freedom Industries facility into the Elk River in 2014, contaminating the water supply for 300,000 residents. Fines to come, lawsuits filed. But that’s not all. In 2008, an ash dike ruptured at an 84-acre solid waste containment area, spilling material into the Emory River in Kingston TN at the TVA Kingston Fossil Plant. And in 2015, in the Animas River in western Colorado, water tainted with heavy metal gushed from the abandoned Gold King mining site pond into the nearby Animas River, turning it a yellow for dozens of miles crossing state lines.
Five easy-to-find examples that impacted a lot of people, but it does not address the obvious question – WHY are these sites next to rivers? Why isn’t this material moved to more appropriate locations? It should never be stored on site, next to water that is someone else’s drinking water supply. USEPA and state regulators “regulate” these sites but regulation is a form of tacit approval for them to be located there. Washington politicians are reluctant to take on these interests, to require removal and to pursue the owners of defunct operations (the mine for example), but in failing to turn the regulators loose to address these problems, it puts our customers at risk. It is popular in some sectors to complain about environmental laws (see the Presidential elections and Congress), but clearly they are putting private interests and industry before the public interest. I am thinking we need to let the regulators do their job and require these materials to be removed immediately to safe disposal. That would help all of us.
Most water suppliers realize that the more natural their land is upstream of their water supplies, the less risk there likely is for their customers. Under the source water protection programs that state, local officials and water utilities implement, the concept is to keep people related activities out, and let the natural forests and landscapes remain. For the most part the natural areas support only a limited amount of wildlife (sustainable) and thereby there natural systems are attuned to compensate for the natural pollutant loads, sediment runoff, ash, detrital matter, etc., that might be created through natural processes. For thousands of years these systems operated sustainably. When people decide there needs to be changes, it seems like the unanticipated consequences of these actions create more problems. Now many of these same ecosystems do not work sustainably and water quality has diminished, increasing the need for treatment and the risks of contamination to the public. It would be better, but decidedly less popular on certain fronts, to provide more protection to natural systems that extend into watersheds (which is most of them), not less.
So this leads to a series of questions that go to the greater questions about natural environments:
Is it really necessary to cull the small Yellowstone bison herd by 1000? What do bison have to do with watersheds? Well, the bison create much less damage to grasslands and underlying soil than cattle due to the size of their hooves. An argument is that we need to cull the herd because they transmit disease to cattle, but Brucellosis has never been demonstrated to move from bison to cattle, so disease is not an answer. What is really happening is that there is competition between buffalo and cattle for grazing. Competition with cattle means that the cattle are on public property, not private ranch lands, and the cattle trample the public lands which creates the potential for soil erosion and sediment runoff. So I am thinking water folks should be siding with the bison. Of course without wolves, there is no natural predator for bison, which raises a different sustainability problem, so maybe instead of killing them, we move them to more of their native ranges – maybe some of those Indian reservation might want to restart the herds on their lands? That might be good for everyone, water folks included.
Part 2 – is it necessary to continue to protect wolves or should we continue to hunt them in their native ranges? Keep in mind wolf re-introduction efforts are responsible for most of the wolf populations in the US, specifically in the Yellowstone area. Without wolves, there is no control of large grazing animal populations (see bison above, but also elk and deer), and there is a loss of wetland habitat because the elk eat the small shoots used by beavers to build dams and trap sediment. Eliminating wolves has been proven to create imbalance. Wolves = sediment traps = better water quality downstream. Sounds like a win for everyone. (BTW there is a program in Oregon to protect wolves and help ranchers avoid periodic predation of calves by wolves so they win too).
Part 3 – Is it really necessary to kill off coyotes in droves? The federal government kills thousands of coyotes and hunters and others kill even more. This is a far more interesting question because it leads to one of those unintended consequences. !100+ years ago people decided wolves were bad (we still have this issue ongoing – see above). So we eradicated wolves. No wolves means more rodents, deer, elk, etc. which mean less grass, less aspens and less beavers, which means more runoff which does not help water suppliers. It also means more coyotes, because there is more food for the coyotes. Interesting that coyotes have pretty much covered the entire US, when their ranges were far more limited in the past. Coyotes are attracted to the rodents and rabbits. But the systems are generally not sustainable for coyotes because there is not enough prey and there is no natural control of the coyotes – again, see wolves above. A Recent Predator defense report indicates that culling coyotes actually increases coyote birth rate and pushes them toward developed areas where they find cats and small dogs, unnatural prey. Not the best solution – unintended consequences of hunting them on more distant land pushes them into your neighborhood. Not the consequence intended. So maybe we keep the small dogs and cat inside at daybreak and nightfall when the coyotes are out and let them eat the rats and mice that the cats chase and once consumed they go away. Coyotes need to eat grazers and rodents but you need the right mix or the grazers overgraze, which leads to sediment runoff issues – which is bad for us. That also seems like a win.
Everglades restoration is a big south Florida issue. The recharge area for the Biscayne aquifer is the Everglades. So water there seems like a win for water suppliers? So why aren’t we the biggest Everglades advocates out there? Still searching for that answer, but Everglades restoration is a win for us and a win for a lot of critters. Federal dollars and more federal leadership on restoration is needed. Which leads to ….
Do we need more, not less management of federal lands? Consider that the largest water manager in the west is the federal government, which has built entire irrigation systems to provide water to farmers who grow crops in places that are water deficient. Those farms then attract people to small towns that consume more of the deficient water. Then people lobby to let cattle graze on those public lands (see bison above), timber removal – which increases sediment erosion, or mining (what could possible go wrong there?). So since the federal government manages these lands, wouldn’t better regulations and control to keep the federal properties more protected benefit water users and suppliers? Contrary to the wishes of folks like the guys holed up in a federal monument in Oregon, or the people who have physically attacked federal employees in Utah and Nevada, more regulations and less freedom is probably better in this situation for the public good. If we are going to lease public lands (and most lands leased are leased to private parties for free or almost free), and there should be controls on the activities monitoring for compliance and requirements for damage control caused by those activities. There should be limits on grazing, timber and mining, and monitoring of same. Lots of monitoring. It is one of the things government really should do. And we need it to protect water users downstream. Again a win for water suppliers.
So as we look at this side issue, ecosystems, bison, wolves, coyotes and the Everglades seem very distant from our day-to-day water jobs. But in reality they are not. We should consider the impacts they might have on water supply, keeping in mind natural system decisions are often significantly linked to our outcomes, albeit the linkage is not always obvious.
My apologies for being offline for a month. It has been very busy. I got back from Utah, and it was tests, reports, etc. Then Thanksgiving – we went to Disney for my stepdaughter. Then the Florida Section AWWA conference, then student final design presentations with President Kelly present for some of it, then finals, then a trip to the west coast, then posting grades, then it’s now. Crazy. And my kitchen is being worked on -see the photos of what is left of it. Not much, and Christmas is how far away. Yikes. At least the wrapping and chopping are 99% done!
In the meantime a lot has happened. Congress cut SRF funding, but passed the transportation bill. They passed WITAF, but provided minimal funding. The debates roll on. A recent South Park episode is all about illegal immigrants from Canada escaping, then there is a wall built, by the Canadian so t hose who left don’t come back, and then we find out who the new president in Canada looks like… well you just have to watch and be scared. Very scared. If you do not follow South Park, well you are just missing it.
Russia had a plane brought down by an apparent ISIS bomb. The Egyptians deny it. Too much arguing about was it or wasn’t it to garner much of an outcry. Best wishes to the friends and families of the victims. Then France had their 911 event sponsored by ISIS, and most of the world is sending their best wishes to the victims, the victims families and the French population. In such events, most of the world comes together. Everybody was French for a day. Best wishes to the friends and families of the victims. Then the couple in California. Best wishes to the friends and families of the victims. But it raises a very disconcerting question, and one fraught with far too many xenophobic concerns as ISIS and their allies like the Taliban, Boko Hiram and others continue to reign terror and violence on the rest of the world. The xenophobic response will be – whom do we trust in the Muslim world? If you don’t believe in blowback, listen to the debates. One commentator points out the xenophobia may actually help ISIS (Donald are you listening?). LOL – of course not. But utilities should expect another round of security costs and analyses in the future.
The Florida Section conference was great. The venue was great (Renaissance at Sea World). The program garnered a lot of buzz and comments. Who knew at a water conference that potable reuse would be the big topic? I also won two awards at the Florida Section conference – a best paper award and the Alan B. Roberts award for Outstanding Service by a member. Wow!! I am humbled. A lot of great utility folks were present at the FSAWW conference. It is a great event for the water industry (that includes wastewater, storm water etc.). The technical program is designed to be good, timely and useful to those that attend. While all utilities struggle with costs, please make time to send your folks if possible. The training cost is reasonable for what you get and who you meet.
My students did well on tests and presentations. President Kelly was impressed with their presentations and projects at the Dean’s Design Showcase. We have never had the Dean at student presentations, let alone the President of the University. My sincere appreciation to him, his staff and those that made it happen. The students were pleased and impressed. And they are getting jobs easily. You can tell people are building and working on infrastructure as most of the graduates get jobs right away, if they don’t have them already.
Grading and the west coast went well. The Fort Myers News Press-Sunday Headline was “Where has all the water gone” – a discussion on how groundwater is depleting across the country including south Florida which gets 60 inches of rain. But the article points out what that climate, rainfall, recharge and other factors have been altered in south Florida as a result of development. We really do make an impact and it is affecting utilities today. This follows another article last week on depleted groundwater around the world. I have lots of photos in my travels from the air – groundwater use is highest where surface waters are limited – i.e. dry areas. Except in dry areas, the groundwater does not recharge. I had a student do a project for his master’s degree that estimated that groundwater depletion is a measureable percentage of sea level rise. More to come on that.
Next the kitchen. I will post photos in another blog.
As I said, a busy month.
