How Did Our Water Get Here?


Here in LA, we expect to see clean drinking water flowing anytime we turn on a faucet. But have you ever wondered where that water comes from?

Tap water in the City of LA comes from several sources — and about 90% of it is imported. The sources we rely on primarily include:  

The Colorado River Basin and the San Joaquin-Sacramento River Delta  

Water from these two regions is managed by the Metropolitan Water District of Southern California (MWD). MWD is a water wholesaler (they sell to cities and utility agencies, which in turn sell to the public).Read more >>

How we captured 80k gallons in recent storms!

If you’ve visited our headquarters in Coldwater Canyon Park, you may have noticed a circular grasscrete in front of our Platinum LEED-certified Conference Center. Well, it’s not just decorative. It’s actually the top of a 216,000 gallon cistern that captures rainwater! (In fact, the visible grate marks only a portion of the entire 70’ x 8’ tank!)

What is a cistern?

When it rains, water that hits our Conference Center’s roof is diverted from gutters, as well as runoff from the surrounding parking lot and walkways.Read more >>

5 Reasons We NEED to Map Trees


You’ve heard it before: trees solve urban problems. They keep cities cool, they clean our air and they capture storm water. They are basically superheroes. With the stress of drought, it’s important to remember why trees matter.

But how can YOU help trees thrive in LA? You have heard of planting trees, maybe you have cared for trees–but have you ever mapped a tree? Mapping trees is an interactive process using TreeMapLA that helps us understand the ways a tree is serving our city.Read more >>

LA StormCatcher: You Asked, We Answered


In early November, we debuted our groundbreaking pilot project: LA StormCatcher (#LAStormCatcher). The collaborative brings Los Angeles County and City agencies and community members together to capture stormwater in the face of ongoing drought and a changing climate reality.

Our first pilot site, located in North Hollywood, kicks off a series of renovations designed to show how capturing stormwater at home can increase local water supply, reduce flooding and improve water quality. The project launched with a  press conference that brought a rush of positive buzz and interest, and even had LA’s own Mayor Garcetti and County Supervisor Sheila Kuehl in attendance. Read more >>

What is #LAStormCatcher?


Have you heard the news? TreePeople is facilitating a groundbreaking collaboration between our region’s top water agencies, with the help of the engineering firm Tetra Tech, to help fight our Stage 5 drought emergency.

The project includes the Los Angeles Department of Water and Power, the Los Angeles County Flood Control District, and the City’s Bureau of Sanitation working together to show Angelenos how the coming winter rains can be harnessed for water resilience.

The partnership, known as the Greater Los Angeles Water Collaborative, is set to unveil the first pilot site in a series of residential installations that promise to turn Los Angeles’ traditional approach to water upside down.Read more >>

Is Los Angeles Ready For El Nino?


El Niño is likely to be heading our way this winter, bringing upwards of 30 inches of rain to Los Angeles. So, the drought is essentially over—right? Wrong.

Well, that is, unless we prepare properly.

Unfortunately, as the climate shifts, we can expect to see drought and floods as two sides of the same coin. As we adapt to this new norm, we can expect both drier conditions and more severe storms. Unless we adopt new habits, like learning to responsibly capture those drops, we can expect drought conditions to continue.… Read more >>
