Rainwater Harvesting

Rainwater Capture

Rainwater Harvesting or Rain Capture is becoming increasingly popular for landscape irrigation due in part to recent improvements in drip irrigation technology and the increasing cost of municipally supplied potable water. One inch of rain on a 2000 square foot roof generates over 1000 gallons of free water.

Landscape Irrigation and Kinetic Water Features

Landscape Irrigation and Kinetic Water Features are systems incorporating lawn sprinklers, tree or shrub drip irrigation, as well as small backyard ponds, waterfalls, and wildlife drinkers. Darco Tanks supplies rainwater storage for landscape irrigation and water features at commercial buildings, schools, golf courses, parks, highway rest stops, and cemeteries. Anywhere water can be collected, reused, or recycled cost effectively, you will find corrosion and rust proof fiberglass underground storage tanks.

Rain Harvesting

Rainwater Harvesting

Roof water generally carries a variety of undesirable elements into any rain capture storage system. Screening or coarse filtering the water before it fills the storage tank is desirable provided the filter has the capacity to process the rain as fast as it falls.

High Volume Overflow Bypass

Always design your storage system with a high-volume bypass to safely divert excess rainwater that cannot be stored fast enough during a downpour. Also consider a tank overflow to release any excess water when the storage system is completely full. Both the Bypass and Overflow must be directed away from the tank and discharged where it will not cause erosion or building damage.

Rainwater collected from summer storms can be used later in the fall when wells and local reservoirs are being strained. Circulation tanks increase the water volume and quality, stabilize the temperature, and provide storage when the system is shut down for cleaning or routine maintenance. Make-up water for evaporative loss can often be provided by rain if an underground storage tank is part of the design.
