Water Authority helps member agencies advance projects

Water recycling is an important element of the Water Authority’s diversification strategy, and it is expected to meet about 6 percent of regional demand in 2020. To move toward that mark, the Water Authority worked with several member agencies in North County to request $3.4 million from the state for a series of coordinated water-recycling initiatives through the Integrated Regional Water Management Program.

The innovative North County partnership matches locations where demand for recycled water is high with facilities that can meet that demand even if that means crossing jurisdictional lines. The strategy to maximize recycled water use gained momentum in 2010 when the planning phase garnered a $1.5 million award from the state Department of Water Resources. The North County coalition continues to work with the region’s representatives in Washington, D.C., to secure $50 million in federal funding.

When finished, the North San Diego County Regional Recycled Water Project will add nearly 30 million gallons per day of recycled water to the regional water supply portfolio, offsetting the potable water demand of approximately 75,000 households and reducing reliance on imported supplies.

The city of San Diego (lower left and upper right) is moving forward from its Water Purification Demonstration Project toward planning for a full-scale potable reuse project.

Residents embrace water reuse

The latest public opinion poll by the Water Authority showed extensive and growing support by the public for water purification and recycling. More than 70 percent of respondents either strongly favored or somewhat favored using advanced treated recycled water to bolster drinking water supplies.

That represented a sustained increase in support for advanced treatment over the 2009 and 2011 surveys, in which 63 percent and 67 percent of the respondents respectively either strongly favored or somewhat favored use of the technology. Support for advanced purification techniques has increased substantially since 2005, giving the region momentum toward another local water supply option.
