In an active rainwater harvesting system, rainwater and snowmelt runoff is directed to catchment areas that then conveys the water to storage barrels or tanks, which are either installed above or below ground. This water can then be pumped as needed to your landscape irrigation system, a landscape faucet or even through a filtration system into the home for use as potable water.

An active rainwater harvesting system is made up of four distinct parts.


Catchment Area

The catchment area is the impermeable surface or group of surfaces that creates rainwater and snowmelt runoff. The catchment area along with the yearly rainfall in your area determines how much water you can catch and store per year.


Collection Points

Collection Points take many form such as gutters, downspouts, canales and catchment basins below downspouts and canales. Collection points are the link between the catchment area and the conveyance system.


Conveyance System

The conveyance system is typically buried pipes that move the rainwater and snowmelt runoff from your home to the storage system, which are typically made up of above ground rainwater barrels or buried rainwater cisterns.


Storage & Use

Once the water has reached the storage it can then be used at need in a variety of ways. Typically in New Mexico active rainwater harvesting systems are used to water our landscapes; however, San Isidro Permaculture also specializes in the installation of rainwater harvesting systems where the water passes through a filtration system so that the rainwater can be used as potable water in the home.
