Pure Water San Diego Projects Underway After Receiving Milestone Permit

/in , , /by /Water News Network

Pre-construction activities at the North City Water Reclamation Plant and the future Pure Water Facility are underway as part of Phase 1 of the Pure Water San Diego program. More than 80,000 cubic yards of soil have been moved to date during initial site work, the equivalent of approximately 25 Olympic sized swimming pools.

Last month, the San Diego Regional Water Quality Control Board adopted an order granting a National Pollutant Discharge Elimination System, or NPDES permit, to the City of San Diego to add purified water to the Miramar Reservoir for Phase 1 of the Pure Water San Diego program. The approval is a major milestone for the program.

Pure Water San Diego Projects Underway After Receiving Milestone Permit

Pre-construction activities at the North City Water Reclamation Plant and the future Pure Water Facility are underway as part of Phase 1 of the Pure Water San Diego program. More than 80,000 cubic yards of soil have been moved to date during initial site work, the equivalent of approximately 25 Olympic sized swimming pools.

Last month, the San Diego Regional Water Quality Control Board adopted an order granting a National Pollutant Discharge Elimination System, or NPDES permit, to the City of San Diego to add purified water to the Miramar Reservoir for Phase 1 of  Pure Water San Diego. The approval is a major milestone for the program.

NPDES permits contain discharge limits, monitoring and reporting requirements, and other provisions to ensure water quality and public health. The NPDES permit issued to the City is the first for a reservoir augmentation project in the state of California.

By implementing Phase 1, the City will be able to produce and store 30 million gallons per day of local water supplies and decrease its reliance on imported water.

Pure Water San Diego Phase 1 includes several projects

Phase 1 includes a series of pipelines and facilities to convey purified water to Miramar Reservoir. Adding the purified water to Miramar Reservoir will increase the reservoir’s beneficial use and optimize protection of water quality. The purified water will blend with the City’s imported sources and be treated again at the Miramar Water Treatment Plant and distributed to the public.

The purified water distribution area will include the portion of the City of San Diego that receives potable water from the Miramar Water Treatment Plant in addition to the City of Del Mar.

Phase 1 of Pure Water San Diego includes several projects: the Morena Pump Station and Pipelines, the North City Water Reclamation Plant Expansion, the North City Pure Water Facility, and the North City Pure Water Pump Station and Pipeline.

Water Recycling Project to Expand San Diego Region’s Local Supply

/in , , /by /Water News Network Mentioned: San Diego County Water Authority

A water recycling project that will purify treated wastewater into drinking water for East San Diego County is moving toward its completion date after the Helix Water District Board of Directors authorized the signing of water purchase agreements.

The East County Advanced Water Purification Project is a collaborative, regional effort to diversify the district’s water portfolio and provide a drought-proof supply. The  water reuse project will further enhance reliability by purifying treated wastewater using Lake Jennings and other facilities.

The Helix Water District Board of Directors authorized its General Manager to sign water purchase agreements for the East County Advanced Water Purification Project at a special meeting on May 27.

Questions Simmer About Lake Powell’s Future as Drought, Climate Change Point to a Drier Colorado River Basin

Sprawled across a desert expanse along the Utah-Arizona border, Lake Powell’s nearly 100-foot high bathtub ring etched on its sandstone walls belie the challenges of a major Colorado River reservoir at less than half-full. How those challenges play out as demand grows for the river’s water amid a changing climate is fueling simmering questions about Powell’s future.

Essential Repairs Completed on Pipeline 5 in North County

The San Diego County Water Authority and its contractors have completed essential repairs on a section of Pipeline 5 in North San Diego County between Fallbrook and Escondido. The repairs included installing 156 feet of carbon fiber liner inside the 96-inch pre-stressed concrete cylinder pipe to extend its service life. The pipeline was returned to normal service over the weekend – ahead of the original schedule.

Cutting-edge technology improves pipeline structure

The lining for Pipeline 5 is a material made from layers of carbon and glass fibers combined with polymers that are engineered to efficiently and effectively improve the structural integrity of large-diameter pipelines.

“The timely upgrade to this section of Pipeline 5 is part of the Water Authority’s proactive asset management program,” said Jim Fisher, director of operations and maintenance at the Water Authority. “A key element of providing a safe and reliable water supplies is continually assessing our 310 miles of large-diameter pipeline and making the upgrades necessary to continue serving the region.”

The essential repairs followed similar repairs on nearby Pipeline 4 last year. The Pipeline 5 project started in early April, about the time most Water Authority employees transitioned to working at home due to the COVID-19 pandemic.

“The crews adapted quickly to implement safeguards to protect their health while moving forward with the critical repairs,” said Peter Milligan, engineer at the Water Authority. “We made sure to limit the number of people on-site, wear masks, and maintain a safe physical distance inside where possible.”

Proactive asset management program maintains critical water infrastructure

The asset management program uses cutting-edge technologies, like carbon fiber lining, to monitor and maintain the condition of important regional water infrastructure. Making preventative repairs ensures that regional water service will continue uninterrupted.

Pipeline 5 was built in 1982 and is part of the Water Authority’s Second Aqueduct, which consists of Pipelines 3, 4 and 5. Along with Pipeline 3, Pipeline 5 delivers untreated water from Lake Skinner in southwest Riverside County to the Lower Otay Water Treatment Plant in southern San Diego County.

An analysis to determine a long-term solution to maintain the Second Aqueduct in North San Diego County is underway.

Season’s Last Snowpack Survey Confirms Dry Winter. California Inching Toward Statewide Drought

/in , , /by /The Sacramento Beeby Dale Kasler

The last Sierra Nevada snowpack measurement of the season on Thursday confirmed what California officials have feared for months: The state has suffered through a dry winter.

The state Department of Water Resources announced that the snow was just 1.5 inches deep at its traditional measuring spot at Phillips Station, a vast field off Highway 50 near Echo Summit. The “snow water equivalent” was just a half an inch, or just 3 percent of average for this time of year.

The Phillips measurement was an outlier. A broader measurement taken by 130 electronic sensors throughout the Sierra revealed an average snow water equivalent of 8.4 inches, or 37 percent of average for this time of year.
