San Diego, Calif. – The regional chapter of the American Public Works Association today conferred two Project of the Year awards on the San Diego County Water Authority for a pipeline upgrade in Scripps Ranch and a rebuilt pump station near Miramar Reservoir, both of which will help ensure reliable water deliveries across the San Diego region.

Most of California was on track for one of its driest winters on record as recently as February as a result of persistent (one might even call it resilient) high pressure ridging along the West Coast during the first half of winter. Recall that December 2017 featured the largest wildfire in modern California history, following on the heels of the most destructive and deadly wildfire event in the state’s history just months earlier in October. Through late February, Sierra Nevada snowpack was tracking near its lowest level in recorded history–on par with the near-total snow drought of 2014-2015.
Virtually every newspaper in the state of California is marching in the Proposition 68 parade. The Parks, Environment and Water Bond promises to spend $4.1 billion on state parks, habitat conservation, ocean clean-up and many more water-related projects. Who doesn’t love parks? Who can’t see the need to conserve? Yet, here we are on the curb, unable to get in step.
Rainwater is a precious resource in California and environmentalists are promoting a ballot measure that aims to protect homeowners who want to collect that water from higher taxes. It doesn’t happen often, but Proposition 72 actually has unanimous support from Democrats and Republicans in the Legislature, along with business, labor and environmental groups. In fact, there is no formal opposition to Prop. 72, which promises some rainy day relief.
Nortek Security & Control LLC has moved its headquarters to a new, 82,000-square-foot building in the Atlas at Carlsbad complex in Carlsbad, where it operates its research, engineering, product development and executive offices. The company is a leader in smart connected devices and systems for residential smart home, security, access control, AV distribution, and digital health markets.
Like a bad penny, a plan to tax water keeps turning up in Sacramento. That’s right: under two proposals circulating in the Capitol, California would start taxing the most fundamental resource on the planet. Such taxes would needlessly drive up costs for families already struggling to make ends meet and undermine the very goals that proponents profess.
While looking for ways to optimize the San Diego region’s water supply, San Diego County Water Authority engineers realized the potential to link the new Olivenhain Reservoir with the existing Lake Hodges just to its east. Not only would connecting the lakes by a pipeline facilitate movemnt of Lake Hodges’ water through the regional distribution system, but the Water Authority could capitalize on a rare opportunity to generate electricity.
The resulting pipeline rises 770 feet from Lake Hodges to the Olivenhain Reservoir. Moving water uphill requires two 28,000-horsepower pumps sitting 10 stories underground. When water flows downhill through the same pipeline, it generates up to 40 megawatts of electricity, enough for 28,000 homes. The Water Authority generates power during the day when energy prices are highest. It pumps water back uphill at night when energy costs are lower, creating revenue in the process.
Completed in 2012, the Lake Hodges Projects facilities allow water stored in lake Hodges to be delivered to the Twin Oaks Valley Water Treatment Plant prior to distribution to a majority of the county. This also gives the Water Authority the ability to store 20,000 acre-feet of emergency water at Lake Hodges when the entire Emergency Storage Project is finished.
