Future of Reuse

The Future of Regional Water Reuse:
Pure Water Southern California

Now is an exciting time for recycled water programs across California. In December 2023, after nearly a decade of careful planning and review, with input from scientists and public health experts, the state released new direct potable reuse regulations that now permit the purification of recycled water for direct use in our drinking water systems. This has big implications for our Pure Water Southern California Program.

Tree Rebate

New Rebate for Trees:
Supporting Our Turf Replacement Program

Trees are nature’s superheroes. Metropolitan’s new tree rebate recognizes the invaluable role they play in maintaining healthy and resilient urban environments. Trees act as natural air purifiers, and their leaves and branches provide cool refuge with much-needed shade. That’s why Southern California residents can now receive a $100 rebate per tree for up to five trees planted while they replace thirsty grass with a more sustainable and water-efficient landscape.

Water Quality Laboratory:
Highlighting Our Talented Staff

Just who are the people behind-the-scenes at Metropolitan providing award-winning drinking water for our six counties? They are the ones who run thousands of tests every year using the latest and best technology at Metropolitan’s renowned Water Quality Laboratory in La Verne.

The lab was established 50 years ago, the same year the Safe Drinking Water Act launched. This dedicated and highly skilled staff – about 100 employees who handle a wide range of assignments and initiatives – are all focused on the same mission. They safeguard the quality of drinking water we provide to our 26 member agencies and the communities they serve. As we recognize the anniversary of the lab, let’s look at some of our many talented water quality staff in action.

It’s fitting that concentric circles are the cover design motif for Metropolitan’s latest publication, Leadership Today, Water Tomorrow. Concentric circles have a common center and run parallel. Metropolitan’s common core is providing reliable and safe water to Southern California in an environmentally and economically responsible way. The way we do that has many layers.
