Underground Water Storage Tanks
POTABLE WATER (often called Domestic water, Drinking water, or Culinary water) is suitable for human consumption or use in the preparation of food. Darco manufactures both Fiberglass and Polyethylene Underground Water Tank systems for Potable Water Storage. Such potable water storage systems can serve individual homes or an entire subdivision based on the storage capacity requirements.
The Residential Storage System illustrated in drawing #1 incorporates 6000 gallons of storage and a submersible bottom suction relay pump which delivers water to the hydro-pneumatic pressure tank inside the dwelling served. Relay pumps may be submerged inside the potable water storage tank itself, located in a remote wet well, in the basement of the building, or in a small pump house located above the tank. Choose the pump style and location which best fits your particular water system size and configuration.
Commercial / Industrial applications often require higher pressure or flow than our internally mounted residential style bottom suction pump can deliver. In such cases, a "wet well" constructed of PVC pipe is installed adjacent to the potable water storage tank and fitted with a higher horsepower center suction deep well style relay pump, as illustrated in drawing #2.
The High Volume Community System illustrates several large fiberglass storage tanks manifolded together to feed a wet well located under the pump house. Well water can be filtered or treated on the way to storage, and then delivered into the community service piping. Large potable water storage tank systems allow chlorination contact and also provide a low cost fire protection water supply for the fire department. Fire trucks can draft directly from a properly sized manifold extension and suction hydrant located near the tank system.
In all 3 illustrations, the Darco potable water supply vessels are out of sight, cool, secure, and frost free. There is no ugly above ground high profile structure to detract from near by real estate value, block the view, or attract vandalism.
