Stormwater / Rainwater Utilization
If an 1800 s.f. ranch home can generate 30,000 gallons* of rainwater per year from it's roof, imagine the amount of rain that can be used from a larger building! Rainwater is naturally soft, so it's great for washing clothes, and it's free, so it's great for saving (harvesting), and using for nonpotable (nondrinking) purposes.
There are many countries, and areas in the world, where it is illegal to use potable (drinkable) water for nonpotable purposes. In those areas law prohibits the use of potable water for such things as irrigation, car washing, and toilet flushing. In the current environment of ever increasing water shortages, it is only likely that these water use limitations will be ever more widespread. Why DO we flush toilets with DRINKING water? Every gallon of rainwater that is harvested and used for a nonpotable purpose, is a gallon of water that does not have to be drawn from the aquifer. By harvesting and using rainwater,the environment is protected, stormwater runoff is reduced, and the aquifer is used in a more sustainable manner.
Commercial / Developers: Do you want your project to be more environmentally sound, while at the same time, increasing your usable space? Do you have a project that does not have room for the same 'typical' ponds that take up valuable area? Subsurface rainwater storage, and utilization of the rainwater for irrigation, toilet and urinal flushing, etc. could be an answer that reduces, and in some instances eliminates the surface ponds. Rainwater harvesting, in combination with bioretention, infiltration, and /or raingardens, could increase usable space, while better managing the stormwater impact of your site.
Builders: Are you offering your customers the option to collect, store, and utilize rainwater for nonpotable purposes? Are you offering your customers options that allow them to use their rainwater, while at the same time managing the stormwater from their site in a sustainable manner?
Homeowners/ Business owners: Served by a municipal water supply and pay the municipality both water and sewer charges on a per gallon basis? Have a private well, but would like to do your part to protect the aquifer by reducing your draw on it? By harvesting and using rainwater for nonpotable purposes, you could easily reduce your dependence on your current water source by TENS of thousands of gallons per year.
