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 >>

“Good for your body, good for your mind, good for your confidence.”

At least, that’s how Vahagn Karapetyan, one of our Volunteer Supervisors, describes his involvement with TreePeople. In his years of service, we’ve truly come to rely on him. In fact, there’s an ongoing belief in our Forestry Department that when Vahagn signs up for an event, you can count him to do the work of 10 people.

Vahagn has been with us for over four years now, originally signing up for our Park Work Days here in Coldwater Canyon Park while he was still a student at UCLA.Read more >>

Nicely Done, LA: Healthy Trees and Safe Sidewalks Ahead!


Since last summer, TreePeople has championed the protection of our urban trees as the City of LA prepared to launch its 30-year sidewalk repair program. This was triggered by a city settlement that secured more than $1.4 billion to make our sidewalks more accessible for all Angelenos.


The way we see it, these sidewalk repairs provide a once-in-a-lifetime opportunity to upgrade our infrastructure to promote accessibility, mobility, safety and even our city’s sustainability. That’s why we’ve worked to educate councilmembers through the process to ensure that, in light of these repairs, our urban canopy is protected, and that we leverage this innovative opportunity to retrofit sidewalks to capture stormwater.… Read more >>

An Open Letter to Angelenos in a Time of Drought

You can’t care about trees without caring about water. The two are intimately connected.

That’s why TreePeople has been committed to take rainwater harvesting to scale for over 20 years. Rainwater can and should be a significant part of our water supply.

Each month, hundreds of people attend our workshops and install rain tanks at home. It hasn’t always been so easy. In the past, when drought wasn’t on people’s minds, the dominant mindset was that Los Angeles is a desert–assuming we didn’t get more than a few drops of water a year.Read more >>

Speak Up for LA’s Water Future


El Niño isn’t panning out to be the drought buster we had hoped.

Despite the recent rain, scientists believe prolonged drought is in California’s future. We shouldn’t be surprised. The links between climate change and extreme weather patterns are undeniable. Weather satellites marked February as the hottest month on record, and our recent weather has been erratic. Now is the time to take action.  For 20 years, we have been LA water leaders, advocating for a secure local supply. Will you join us now in our efforts to protect LA’s water?Read more >>
