Information on using CULTEC products for Water Harvesting

Rainwater Harvesting

CULTEC has launched a residential rainwater harvesting (CULTEC RRH) program that can greatly reduce household demand for non-potable water supply. In such a system, the Contactor and Recharger chambers capture and store rainwater that can be used for such activities as irrigation, fire prevention, sprinkler reserve and exterior cleaning.

For centuries, people have relied on rainwater harvesting to supply water for drinking, household, livestock and agricultural uses. Today, rainwater harvesting is popular in parts of Europe, Hawaii, and Japan and is mandatory in such places as Bermuda, parts of Australia and New Zealand. There are over 250,000 known users in the U.S. and a thriving rain collection industry in Texas, Arizona, California and Oregon.

The CULTEC RRH program offers multiple benefits to builders and homeowners. Specifically it:

  • Creates a water reserve at no additional cost and without environmental impact.
  • Offers potential cost-savings to homeowners by reducing their demand on municipal or well water for household uses; for example, a typical lawn can require about 3000 gallons (11355 liters) of water a month, depending on the climate.
  • Stores a large volume of water in a small area.
  • Provides cost-effective stormwater management, eliminating poor drainage around the house.
  • Allows builders to earn LEED credits for CULTEC RRH installations when projects are designed per LEED requirements.

A CULTEC RRH System consists of collecting rainwater via a gutter or other drainage structure, conveying the water through a small water quality unit such as a CULTEC StormFilter T-80 to remove leaves and debris and then piping to one or more CULTEC Stormwater Chambers based on the storage volume. An impermeable liner is used within the chamber bed to prevent infiltration into the ground, thus creating a subsurface storage area. A submersible pump then conveys the collected rainwater from the chambers to a spot where it will be used. An overflow area must also be employed for systems not installed below the frost line to prevent freezing and heaving.
