![]() ![]() Recycled Water: Water which, as a result of treatment of waste, is suitable for direct beneficial use or a controlled use that would not otherwise occur and is therefore considered a valuable resource (Current California Water Code 13050-13051).Rainwater: A form of stormwater that is collected directly from roof surfaces which can have lower levels of pollutants than other sources of stormwater.Post-storage treatment: Practices that are used to remove fine particulates, dissolved pollutants and microorganisms from harvested rainwater.Pretreatment: Treatment of harvested stormwater prior to entering the storage unit typically processes that remove trash, gross solids, and particulate matter.Pre-storage treatment: Best management practices that are used upstream of the storage unit.Potable water: Water that meets drinking water standards.Overflow Siphon: Functions as a trap to keep out vermin and also to evacuate floating pollen and debris in the tank during rain events.Non-potable water: Water that does not meet drinking water standards.Make-up water supply: Municipal water or other reliable water source that is used to supply water for beneficial use in the event that harvested water is not available.Harvested water: Water that is collected from impermeable surfaces, such as rooftops and parking lots, and stored for future use.Green Roof: a rooftop treatment practice where a thin planting media is established on roof surfaces and then planted with hardy, low–growing vegetation.Extreme caution should be observed in cold climates. ![]() Only suited for warm weather applications. First flush device: A device that diverts runoff generated during the beginning of a rainfall event, which carries higher levels of debris and contaminants from collection surfaces, from entry into storage components.Dry running protection: System for protecting a water pump against running when no water is present.Disinfection: Reduction of viable micro-organisms to a level that is deemed suitable for the intended use.Collection efficiency: Harvested water volume as a percent of the total rainfall on the source area during a certain period of time.Beneficial use of stormwater: Use of stormwater to meet water demands, including but not limited to: irrigation, drinking, washing, bathing, cooling, and flushing.Backwash: Water that is pumped in reverse through filters, removing trapped sediment and other collected material. ![]()
