On Tuesday October 13th 170 water professionals gathered in Downtown Los Angeles for a drought symposium sponsored by the Los Angeles Basin Section of CWEA and WateReuse California. Speakers provided technical updates on water supplies that agencies can tap into right here in the LA Basin – including recycled water, desal and stormwater. The theme of the event was building a more resilient and reliable water supply for LA by embracing the one water concept.

Increasing the Use of Recycled Water

For the Water Resources Control Board’s Division of Drinking Water ensuring consistent and reliable recycled water regulations are a key focus as more projects enter the final planning stages according to Kurt Souza, a Deputy Director of DDW’s Southern California office. On April 1st the Governor implemented mandatory conservation and required regulators to speed the permitting process for local water supply projects including recycled water projects.

This includes looking at new regulations for surface water augmentation and direct potable reuse (DPR).

“The supply situation is serious. Reservoirs are at record lows and that’s going back to the 1880s.” – Kurt Souza, SWRCB DDW

“In the Central Valley, recent groundwater levels are more than 100 feet below previous historic lows. There is good news – the Governor set a goal of saving 1.2 million acre feet of water and as of August we are half-way to the goal. We’ve saved 612,000 acre feet so far, pretty incredible,” said Souza.

During an October 13th Drought Symposium hosted by the Los Angeles Basin Section of CWEA and WateReuse California, local water leaders discussed the regions resilience in surviving this drought and their preparations for El Niño. The discussion was moderated by Patrick Healy from NBC Southern California.

The panelists emphasized three messages: first, there’s only one water, so let’s treat all sources of water with respect; second, the time is now to fund and build the recycled water and stormwater projects we’ve talked about for decades; and finally, water projects take a decade to build so let’s start building. For the LA area to be resilient through future droughts and floods, more local water projects will need to be built.

The panel included Martin Adams, Senior Assistant General Manager of LADWP; Robert Ferrante, Assistant General Manager of the Sanitation Districts of Los Angeles County; Gary Hildebrand, Deputy Director Water Resources of LA County Department of Public Works; and Traci Minamide, the Chief Operating Officer for the City of LA’s Bureau of Sanitation.

Beyond Nitrification – Benefits of Higher Solids Retention Time Operation

By Dr. Michael Stenstrom, Ph.D, P.E.

 The activated sludge process is the most common method of secondary municipal wastewater treatment; solids retention time (SRT) is the key control parameter for this process. Typically, operating at long SRT is considered only for nitrification, but there are additional benefits of high SRT operation. The presentation will present experimental and literature evidence to demonstrate three major additional benefits of long SRT operation: increased oxygen transfer efficiency; improved biomass particle size distribution, which results in more efficient clarification with fewer effluent particles and suspended solids; and enhanced removal of many emerging contaminants such as pharmaceuticals, personal care products, and endocrine disrupting compounds. This presentation will present the results from several treatment plants demonstrating these benefits. A long-term survey of three treatment plants concludes that operating at higher SRT is not as energy intensive as commonly assumed.
