Arizona community's commitment to conservation

Annual rainfall is not very plentiful in Arizona, so water is truly a precious resource. In an effort to conserve water, the city of Sierra Vista, Ariz., located in Cochise County, mandated each new home must have a dedicated hot water return line in the plumbing system. This city code was implemented in 2000, and amended in December 2010 to include an on-demand hot water pump, with nationally recognized electrical and plumbing standards.

In a peer-reviewed study from 2009-2010, commonly referred to as the “2006 EPA Report,” calculations found that 80 million gallons of water was being wasted each year due to residents turning on a faucet and letting the water run until it got hot. The study was conducted by Dave Grieshop, a retired military engineer who owns Reality LLC, a consultancy company. Grieshop is an EPA WaterSense-certified home inspector and professionally accredited in rainwater harvesting by the American Rainwater Catchment Systems Association. Since 2009 Grieshop has spent time analyzing municipal plumbing codes and providing structured plumbing design for builders and architects.

An effective solution for reducing that water waste in Sierra Vista was with the ACT D’MAND Kontrols pumping system, a product that provides hot water on demand. Through a rebate program with the Cochise Water Project in 2013, more than 100 ACT D’MAND Kontrols pumping systems were installed in Sierra Vista homes, along with 600 high-efficiency toilets. Rebates were also offered to homeowners using a certified green plumber.

Grieshop chairs the technical advisory committee for the Cochise Water Project. He installed an ACT D’MAND system in his own home, and at first his wife thought he was crazy, but a week later she said to him, “I’m here to eat crow. That thing is fantastic!”

A survey of homeowners who installed high-efficient toilets and ACT D’MAND Kontrols pumps resulted in positive comments, for example, “I really like that toilet. I like saving water. But I wish I had put that D’MAND pump in 20 years ago. It’s so convenient, I love it.”

The ACT D’MAND Kontrols pump provides energy savings and water savings, along with the convenience of having hot water on demand. When an ACT D’MAND Kontrols system is installed, there’s no need to wait for cold water to heat up because it’s already hot, on demand. Instead of a “cold start,” turning on the hot faucet is a “usable start.”
