The Water Authority supports cost-effective sustainability programs that will benefit the environment and promote thoughtful stewardship of our natural resources. These programs save ratepayers money, reduce the environmental impacts of Water Authority operations, conserve energy and water, and help the Water Authority better anticipate and adapt to the impacts of climate change.


Sustainability projects have been an important part of the Water Authority’s approach to business for years.

Conserving water not only lessens the Water Authority’s dependence on imported water, it also reduces energy costs and the greenhouse gas emissions associated with transporting, treating and heating water. In 2008, the Water Authority’s 20-Gallon Challenge campaign saved approximately 83.7 million kilowatt-hours of energy by bringing regional urban water use to a five-year low.

The Water Authority is now partnering with the Scripps Institution of Oceanography, San Diego State University and the San Diego Foundation to study how climate change will affect San Diego’s future water supply and demand.

In addition to developing renewable energy sources  and cutting its fleet emissions, the Water Authority is committed to becoming a model for sustainability. The agency’s headquarters in San Diego features a water-wise landscape with rotating sprinkler heads and drip irrigation, low-flow toilets and aerators, energy-efficient lighting, and recycling bins in all common areas. As outlined in its business plan, the Water Authority aims to reduce its facility waste and greenhouse gas emissions.

By promoting conservation, improving efficiencies, reducing waste, and supporting renewable projects, the Water Authority can reduce its impact on the environment and make a positive contribution to a more sustainable future for the region.
