The Competition are using Water Storage Tanks
Water sitting in storage tanks for a long time and then used to wash your families clothes = very bad idea
Over time sediment builds up in water storage tanks - the sediment can be a safe habitat for bacteria protozoa and even viruses
Monroe Road Laundromat does not and will not use Water Storage Tanks
*The Overwhelming Majority of Self Service Laundromats do not use Water Storage Tanks!!!
*Monroe Road Laundromat does not and will
not use Water Storage Tanks!!!
Here is why:

Since 1997 my company Ron Perrin Water Technologies has been a leader in underwater inspection and cleaning for the water utility industry. We offer underwater inspection and cleaning services to municipal water utilities so they do not need to drain water tanks or towers to inspect or clean them. Our city drinking water comes from surface waters (lakes, rivers or streams) or ground water (well water). After the water is treated it is sent to the water storage tanks & towers where it waits to be used at your tap. Over time sediment builds up in these tanks the sediment can be a safe habitat for bacteria protozoa and even viruses.
Water Storage Tanks Are
Water storage tanks can have a real effect on water quality. Water can stagnate in a tank for a long time before it gets used. When it does eventually make its way to a customerís faucet, the water probably isnít going to taste or smell very good. And, it may even have become a health risk.
According to the Association of State Drinking Water Administrators (ASDWA), design engineers typically emphasize hydraulic concerns when they plan a storage facility, meaning they have worried about how much water can get from one place to another in a given amount of time. But by making sure that there is enough water for emergencies, many storage tanks are much larger than they need to be for everyday use. And many systems keep their tanks full, despite not needing the water.
A full tank does provide constant system pressure and helps systems to be better prepared for emergencies. But problems occur when the water isnít used or continuously mixed. Dead zones can develop inside the tank. That means that the water does not move from its place of residence and stagnates. Continuously mixing the water and making sure that fresh water replaces stagnant water can help control dead zones inside tanks.
Besides over designing, some storage facilities have been built so that the high water level is below the hydraulic grade line of the system, making it more difficult to turn the water over. The hydraulic grade line is an imaginary line that, when plotted, represents the sum of pressure head plus elevation head for various positions along a given fluid flow path, such as along a pipeline or a groundwater streamline. If the hydraulic grade of the system drops significantly, very old water may enter the distribution lines.
Frequently exchanging the water in the distribution system and storage facilities can make water age less of a concern. EPA says, ďsome studies suggest a shelf life of three, five, or seven days, depending on water quality parameters. When possible, the water level in standpipes should fluctuate widely through withdrawal of a larger amount of water than normal one day and refilling the next.Ē
Biofilms Form and Grow
Microbial survival and growth can occur when water moves slowly or becomes entrapped in dead-end sections of the distribution system, notes EPA. If any organisms have entered the system, biofilms can form within the network, including storage tanks. Biofilms usually appear as a patchy mass in pipes or as a uniform layer along inner walls of a storage tank. Coliform bacteria may colonize within the biofilm layer, causing taste and odor problems.
Factors that provide optimal growth conditions for microorganisms include long water-detention times in tanks and lines, adequate nutrient levels, and warm temperatures. In addition, long detention times increase the likelihood that opportunistic pathogens will re-grow.
Opportunistic pathogens are any disease-causing organism, bacterium, virus, helminth, or protozoan that slips through the treatment processes or enters the system during times of pressure loss and finds the opportunity or favorable circumstances to lodge or reproduce in organic material, bacterial slime, or other material that it finds attractive.
