Basic Parts of a Rain Harvesting System

Basic Rain Harvesting System

This diagram shows a rainwater harvesting system that can collect a substantial amount of rain for landscapes, agricultural uses, washing cars, flushing toilets and, when treated properly, safe drinking water.

1.)  This diagram shows a metal tank (which comes in sizes ranging from 3,000 to 5,000 gallons). A rain harvesting system from 250 to 3,000 gallons could easily substitute a less expensive poly tank for the metal tank.

2.)  A pre-tank filtration system helps filter debris from the rainwater before it runs into the tank. This helps to keep the water clean.

3.)  The level gauge and auto refill are important to the system’s operation. When the tank’s water level reaches a set low point, it is automatically refilled just enough to allow the irrigation system to keep irrigating.

4.)  Pre-pump filtration takes water from the cleanest portion of the tank, which is about 6-inches below the water’s surface.

5.)  The pump system is safely houses in an integrated pump protection enclosure.

6.)  Post pump filtration helps prevent irrigation components from being clogged by fine debris that might be in the rainwater.
