Pilot Project for Free Rainwater Harvesting System

2 Comments


Colorful hot air balloons ascending against a clear blue sky.The Albuquerque Water Authority andthe New Mexico Water Collaborative have partnered to launcha pilot project intended to help residents make better use of rain, rather than allow it to drain away, giving themthe opportunity to repurpose collected rainwater for landscaping.

In Phase 1 of this pilot program, residents can sign up to applyfor a free system, which, on its own, could cost $10,000 or more.The goal is to educate folks how they can make small changesthat would have measurableimpact on the amount of potable water that can be collectedto support the landscape. The bonus would be lower water bills, plusthe environmental benefit of conserving both water and energy.

Special Report From California Water Alliance


A green plant growing from dry, cracked soil.The California Water Alliance (CalWA) recently requested that the California Water Commission endorse Governor Brown’s commitment to the public to use dedicated water bond funds to build water storage facilities, considered to be a large reason why voters approved California’s water bond ballot measure last November.

Excerpted from the press release, according to California water alliance member Bittencourt, “We are in the fourth year of a crippling drought; each rainfall that passes through is a lost opportunity. Creating more reservoirs will protect the state from future disaster and should remain a top priority for the Governor, the legislature, and the Commission as it already is a top priority for Californians.”

The report goes on to say that 67% of voters passed Proposition 1 to fund waterquality, supply, treatment and water storage projects.

Recent reports indicatethat 80 % of California is experiencing “extreme drought”, creating third world living conditions for some residents in central California.

The California Water Alliance is calling on Governor Brown and the California Water Commission to enforce the promise of water storage be part of that program. Click here to read the entire release.

Harvested Rainwater Reduces Energy Consumption

In places such as Bermuda and the US Virgin Islands, the harvesting of rainwater is required by local codes for all new construction. Also, states such as Hawaii andTexas have or are developing design guidelines for rainwater harvestingsystems. Additionally, San Juan County in Washington State has been issuing building permits with rainwater as the sole source of water for several years.

Harvested rainwater is free of most of the pollution typically associated with surface water runoff. Furthermore, usingharvested rainwater both reduces peak storm water discharge velocities associated with impervious surfaces and reduces the draw on aquifers and municipal water supplies. Collected rainwater does not have to be pumped up from a well or be conveyed from a distant central treatment facility. This reduces energy consumption, reduces the use of chemical treatment and disinfection as well as it is less disruptive to the natural hydrologic cycle.

On October 12, 2009 the Washington State Department of Ecology issued an Interpretive Policy Statement clarifying that a water right is no longer required for roof top collection. Since January 25, 2011, King County has adopted rainwater harvesting for potable use in single family residences as a supplemental water source. Other Washington State Counties have since adopted rainwater collection for potable use in single family residence as well.
