Aging Public Water Systems Money Sits Unspent

tap-357252_1280Water is vital to public health, maintaining our environment and preservation of quality of life. We simply can’t live without water. Our nation’s public water system infrastructure is in dire need of upgrading. Many systems are so old that the maintenance costs are beginning to overtake the cost of replacement.

The EPA offers funding for low interest loans to public water systems. According to a Washington Times article, ‘The U.S. Environmental Protection Agency projects it will cost $384 billion over 20 years just to maintain the nation’s existing drinking water infrastructure. Replacing pipes, treatment plants and other infrastructure, as well as expanding drinking water systems to handle population growth, could cost as much as $1 trillion.”

Furthermore, the article goes on to note that in spite of demand, more than $1 billion sits, unspent, in a funding pool managed by the largest federal aid program for drinking water improvements, the Drinking Water State Revolving Fund, (as reported after a review by The Associated Press).

Why would available funding to improve public water systems, necessary for public health and a strong economy, be left sitting in government accounts? According to CNBC, “Project delays, poor management by some states and structural problems have contributed to nearly $1.1 billion in congressional appropriations sitting unspent in Drinking Water State Revolving Fund accounts as of Aug. 1.”

Adding to the muck, the money that is being tapped is largely used for services associated to drinking water, but not infrastructure improvements. The CNBC article goes on to report “About 1 in 5 dollars in recent years has gone to purposes such as paying the salaries of state employees and contractors. Those expenses are allowable but leave less for the repair and replacement of leaky pipes, deteriorating treatment plants and century-old storage tanks.”

So, while funding is available for municipal and county water systems improvement, almost 20 percent of the money drawn from this grant pool is currently being used to pay for administrative costs, leaving less money available for the $1 trillion estimated that will be needed across the board – for just water infrastructure improvements, not inclusive of roads, bridges, energy, etc.

There are many safe and sustainable options available to supplement public water systems with rainwater collection. While available in many areas, we need more education about the value and  stability achieved by adding a rainwater collection system to a residence or commercial property. In some areas, a rainwater collection system could be sole-source for whole house usage, or a supplement to city water, easing the burden on public systems caused by population growth and aging infrastructure.

Rainwater Collection Steel Tank Photo Gallery

Laundry Building SeattleWith 15 years of experience in the rainwater collection industry, RainBank has assembled a photo gallery of some of the steel tank installations we’ve completed .

With many builds located in the Seattle area, RainBank also has several projects located in the Pacific Northwest, like Portland, OR, Vashon Island and Lopez Island, in 2014, RainBank also directed a steel tank build in Galveston, Texas for the Sea Scouts.

At What Point is Rainwater Collection Too Expensive?

water-49024_640Collecting rainwater for potable and non-potable use should carry the importance of what it is “a safe, reliable source of drinking water” that protects the health and welfare of its users. What is that worth? At what point do we consider rainwater collection to be too expensive? Only hire those that are qualified, not those who are the cheapest.

As rainwater collection becomes an increasingly accepted, sustainable method of water conservation, costs have risen due to design and implementation regulations, as well as major components improvements. As in any industry, qualifications of designers and installers are, and should be scrutinized.

Liabilities need to be addressed for potable and non-potable use, not just for the designer or installer, but for the owner of the system as well.

For non-potable application, care must be given that fixtures, as well as plumbing, are clearly identified as “non-potable water unsafe to drink” and plumbed in such a way that cross contamination to potable water does not occur.  A reduced pressure backflow assemblies (RPBA) or air gap must be installed on city water side of plumbing if non-potable water is connected to any building or dwelling plumbing system. This protects the safety and welfare of users and their guests. A qualified designer/ installer must remain current with plumbing codes that are in effect for rainwater collection.

For potable application, great care must be given to design and installation, after all we’re talking about drinking water and the safety of the user and their guests. EPA standards of quality of drinking water must be met, or the designer, installer, and homeowner can be liable. The American Water Works Association (WWAA), the American Society of Plumbing Engineers (ASPE) along with the American Rainwater Catchment Systems Association (ARCSA) have written plumbing code for RWC which are continuously being updated. The designer needs to know what he or she is trying to remove from the raw water and use the best method of filtration and disinfection to protect the safety and welfare of others. All components including storage, conveyance, filtering, and disinfection must meet National Sanitation Foundation (NSF) requirements for drinking water.

Many counties in Washington State, including King County, require a licensed engineer, with experience in rainwater systems, or an individual who holds a class B water designer certificate or an ARCSA AP. Professionals that are installing pressurized systems are required to have a plumber’s license. This regulation helps protect the health and welfare of the system owner. ARCSA APs must submit continuing education credits to stay current with their endorsement.

We’ll let you decide when RWC is too expensive, but encourage you to consider the value of having your system installed safely and to meet city, county, state and federal mandates.
