The Metropolitan Water District of Southern California has stepped towards the potential advancement of what might be one of the world’s biggest water reusing programs. The area’s Board of Directors voted on Tuesday, July 11 to grant a $13.9 million contract for the development of a propelled water treatment exhibit facility that will take treated wastewater and cleanse it through different propelled procedures to deliver a protected, top notch water source to renew the district’s groundwater.

California is poised for a swift transformation of its electricity landscape — and that could bring tumult if preparations aren’t made soon to maintain quality and avoid reliability problems like rolling blackouts, the state’s leading energy regulator is warning. After decades of dominance by investor-owned utilities, electricity markets in the state are becoming more competitive. Ratepayers today have a growing number of choices for powering their lights, laptops and electric cars — from installing rooftop solar panels and consumer-scale batteries to joining increasingly popular government-run electricity programs known as community choice aggregation, or CCA.

The Sacramento-San Joaquin Delta is 435 miles from South Orange County, but the impact of what happens there is felt as close to home as your shower. The Delta is the heart of the State Water Project. Near Stockton, the Delta is where the tidal forces of the Pacific Ocean meet the outflows of the Sacramento and San Joaquin rivers. Water flows through the Delta before entering a series of reservoirs, pumps and canals that bring water from the Sierras to Southern California.

The San Diego County Water Authority celebrated Tuesday its award for the world’s top civil-engineering project — a network of dams, pumps and pipelines that can protect the region’s water supply for six months. The $1.5 billion Emergency & Carryover Storage Project received the 2017 award from the American Society of Civil Engineers earlier this year, beating out the iconic new One World Trade Center in New York and the Chhatrapati Shivaji International Airport Terminal 2 in Mumbai, India, among other projects. On Tuesday a plaque was officially unveiled at the remote Olivenhain Dam, one of the four key parts of the project.

After weeks of back-and-forth between environmentalists and business interests, Gov. Jerry Brown and legislative leaders introduced a proposal Monday evening to reauthorize California’s cap-and-trade program, the centerpiece of the state’s efforts to battle climate change. The plan consists of two bills: Assembly Bill 398, which would extend the life of the program until 2030 and modify how the cap-and-trade market operates, and AB 617, which aims to address concerns about air quality in communities by increasing monitoring and imposing stricter penalties on polluters.
