Recycled Water Project for Water Stability, Part 2

North Valley Regional Recycled Water Program Projected Completion

By Brian German, Associate Editor

In our continued coverage of the monumental North Valley Regional Recycled Water Program (NVRRWP), Anthea Hansen, general manager of the Del Puerto Water District, talked about the projected completion for the project.

“We estimate the pipeline will be completed by December 2017—less than two years,” Hansen stated. “The first year’s combined quantities, if both cities (Turlock and Modesto) are online at the start date, will be somewhere between 25K and 30K acre-feet per year,” Hansen calculated.

NVRRWP will convey recycled water from Turlock and Modesto, currently being discharged into the San Joaquin River, instead to the Delta-Mendota Canal via pipeline for storage purposes and later use. “The sense that we all have here,” said Hansen, “is that this transaction and this accomplishment will change the future of the Del Puerto Water District for the better. It will give us some stability in our base [water] supply that we know will come year in and year out.”

After many years of working with various agencies and collaborating with  multiple cities, the project has passed all of its major hurdles and is set to break ground within the next few months. Using recycled water from treatment plants will reduce reliance on unsustainable groundwater supplies and also lower the amount of water pumped from the Delta.

“People use water in the cities every day, 365 days a year,” explained Hansen. “The reliability of the supply is so important to us because, for such a long time, we have not had reliability in our water supply,” Hansen noted.

“We have 40-year agreements in place with both cities,” she continued. “As a result of the program, even in the first years, each irrigable acre in the district will receive somewhere between one half to three-quarters of an acre-foot of guaranteed water supply, year in and year out.”

Hansen added the project will sustain a growing population. “Over time,” she remarked, “as the cites grow and the populations expand, the quantities of water are projected to grow over the build-out period for the project.”

Part One of a Five-Part Series

Anthea Hansen, general manager of the Patterson, Calif.-based Del Puerto Water District, described the exciting work to bring more water stability in the form of recycled water to multiple Central Valley cities—in our five-part series on the North Valley Regional Recycled Water Program (NVRRWP)

“After six and a half years of effort,” Hansen said, “we have fully completed all of our environmental documentation, and most of the permitting is in hand.” Recently, the partners have interviewed and selected the preferred firm to construct the Modesto component of the project, so that process is underway.”

cropped-cropped-SLDMWA200x200Logo101714NVRRWP is a collaborative partnership that includes the cities of Modesto, Turlock and Ceres along with the Del Puerto Water District and Stanislaus County to solve the region’s water supply and reliability problemsThe program will provide a new source of water for agricultural customers in the Del Puerto Water District (DPWD), whose supplies have been severely impacted by drought and by environmental restrictions on pumping water from the Delta. Hansen noted the collaboration was the largest obstacle they were able to overcome.

“One of the biggest things that happened recently, a day we were all looking forward to,” noted Hansen, “is when the United States Department of the Interior, Bureau of Reclamation (Reclamation) executed the record of decision for our project, a document that supports not only the federal National Environmental Policy Act (NEPA) documentation but also the signing of a long-term contract. It will allow us to convey and store the recycled water in federal facilities,” she said, “and it will also support the sharing of a portion of the water with the wildlife refugees south of the Delta. That was a big milestone for our project.”

The cities of Turlock and Modesto will provide treated, recycled water to the Del Puerto Water District through a direct pipeline into the Delta-Mendota Canal. The district will then distribute that water to the agricultural customers within its service area.

After so many years already invested in the project, Hansen is excited the plan is coming together. “We worked lockstep with Reclamation for over three years,” Hansen said, “and we did some very extensive and thorough analysis. We had a great team and a good working relationship, and it looks like we are nearing the end of assembling all of the different pieces of this very complicated puzzle.”
