Wadsworth Piping Repair Project Approved
Metropolitan’s Board of Directors has authorized $7 million for a contract and other construction phase activities to repair the pipe lining at Wadsworth Pumping Plant.

Senior Engineer and Program Manager Wayne Thilo made the presentation to the E&O Committee meeting in August.

Located on the west end of Diamond Valley Lake, the Hiram W. Wadsworth pumping/hydro-generation facility is a major control structure and renewable energy producer for water coming from the State Water Project through DVL. 

Water flows through a 2,300-foot-long pressure tunnel to Wadsworth, where it is sent through as many as nine electrical generators that produce up to 3.3 megawatts each. From there, water is released to the San Diego Canal, through which it flows to Lake Skinner and the Skinner Water Treatment Plant, as well as other water facilities in southwestern Riverside and San Diego counties. 

The project will involve replacing epoxy lining in about 2,200 feet of yard piping installed about 18 years ago. These pipes are between 54-192” in diameter.

A contractor will remove the old lining and replace it with new polyurethane lining. Metropolitan staff will establish clearances, dewater the pipes, inspect the construction work, administer the contracts, review the plans and drawing, and return the pipe to service when the work is completed.

Construction is scheduled to begin this fall and will be completed in 2019. 
Shortage Odds Climb on Colorado River
August was an important month for the Colorado River, according to Bill Hasencamp , Metropolitan’s Colorado River Resources Manager. It’s when the federal government forecasts for the next 2 years how much water will be in Lake Mead, the primary reservoir that stores and supplies water to Arizona, Nevada and California, including Met’s Colorado River Aqueduct.

For 2019, there will be no shortages on the River. But after that, the news isn’t so good. According to the U.S. Bureau of Reclamation, low water levels will likely force water shortages in Arizona, Nevada and Mexico in 2020.

A ‘shortage’ declaration is tied to the level of Lake Mead. The reservoir is low thanks to nearly two decades of dry conditions - so low that you could empty into it all the water from our State Water Project and Central Valley Project reservoirs -- and it still wouldn’t be refilled.

And if the lake drops below an elevation of 1,075 feet by the end of next year, water users downstream have to cut back how much water they draw.

The new figures ramp up pressure on water managers in the river’s Lower Basin -- Arizona, California and Nevada -- to finish work on a conservation plan that will benefit the entire river. This agreement, called the Drought Contingency Plan, would be a multi-year plan to incentivize water users to leave water in the lake. Metropolitan’s Colorado River managers aren’t waiting for Mother Nature. Getting a drought contingency plan negotiated with other agencies and Colorado Basin states is a top priority this fall.
Bringing Expertise and Experience to New Job
Having seen and been involved in the addition of ozone treatment at three of Metropolitan’s five water treatment plants, John Sena’s institutional knowledge makes him a valuable new Unit Manager at the Skinner Water Treatment Plant. 

John joined Metropolitan in 2003 as an Electronic Technician at the Mills Treatment Plant, just as the ozone facility was going on-line. By 2007, he was promoted to Control Systems Team Manager at Skinner and was responsible for instrumentation and controls at the Skinner Plant, Diamond Valley Lake, and Skinner Construction & Design areas. 

In 2016, he became the interim plant manager at Weymouth. With his previous experience and knowledge of ozone processes, John was intricately involved in getting ozone facilities up and running at Weymouth. “Experiencing the startup of ozone at three of Met's facilities gave me the opportunity of seeing firsthand the construction and operation of the facilities, and the ability to use and share my experiences to help improve processes and expedite staff training,” says John .

This past July, John was the successful bidder for a Unit Manager position at Skinner. In this new role, he is responsible for all operations and maintenance at the plant. The challenge he says is “leading a diverse group of different operations and trades staff while coordinating the
needs of the member agencies.” What makes it exciting is that “every day brings challenges that require working with different people, learning new things, and solving problems.”
