Efficiency Efforts in Water ServicesList All

Citywide Water Efficiency and Goals

Currently, the energy and water utilities do not offer joint efficiency programs to residential or commercial customers. The City of Phoenix is a major contributor to the Water Use It Wisely campaign, an educational campaign aimed at increasing water efficiency across Phoenix. As a result, water use per capita has dropped 34% since 1996 and 6% in the last two years. The city also retrofits 200-250 income-qualified homes with high-efficiency fixtures and toilets. Phoenix partners with Salt River Project on a water conservation program that encourages residents to reduce water and energy use in landscaping.

Currently, the energy and water utilities do not offer joint efficiency programs to residential or commercial customers. The City has set nonrevenue water-saving goals at their water department, which are aimed at keeping annual water losses below 10%.

Water Plant Efficiency and Self-Generation

The Water Services Department (WSD) partners with local electric service providers to implement energy conservation measures at its facilities. To date, energy conservation measures from these programs have saved 5.8 million kWh annually. The WSD has joined the Department of Energy’s Better Plans Program, setting a goal to reduce energy intensity (kWh/million gallons) by 25% over a 10-year period, baseline year 2015. It is also participating in the DOE’s Wastewater Infrastructure Accelerator through the Better Buildings Program. The city-owned water utility also falls under the city-wide goal to reduce energy use by 20% by 2020 from 2009 levels despite a growing population and water services. The department goal is to operate at the highest level of efficiency and cost effectiveness and has upgraded many of the facilities and pumping stations. In 2018, one of the five ESCOs contracted by the City is under contract to updated water facilities to achieve the 20% reduction target.

Digester gas is used at the 91st Avenue Wastewater Treatment Facility, in boilers to maintain digester temperatures, offsetting its thermal load by 68,000 MMBtu per year. Additionally, a large Energy Services Company (ESCO) is under contract to build and operate a facility recovery and clean-up digester gas that is currently being flared. In 2018, the City constructed and opened a $25M gas capture and treatment plant that will convert methane captured from wastewater to green gas and insert it into the natural gas pipeline—generating $6M annually in gross revenue. The facility will provide an annual energy offset of approximately 640,000 MMBtu, reducing carbon emissions by nearly 45,000 tons/year, which is the equivalent of taking over 70,000 cars off the road or planting over 87,000 acres of trees every year.
