Los Angeles Times article, When it rains, Los Angeles sends billions of gallons of ‘free liquid gold’ down the drain, author Bettina Boxall describes an L.A. where increased stormwater capture projects provide solutions to the current water crisis over time. Stormwater should be treated as a resource instead of throwing it down the drain. L.A.’s original focus was to drain the stormwater as quickly as possible instead of treating it as “liquid gold”.
Stormwater capture projects in Los Angeles are doing more than just replenishing local groundwater supplies. Diverting runoff from flood-prone streets filters out contaminants as stormwater seeps through the ground and increases the production of quality groundwater. L.A. County is focused on increasing groundwater supplies with quality water by utilizing capture programs such as green street projects, spreading grounds, and infiltration swales.
“It’s not just doing groundwater recharge. You are addressing water quality. You are greening communities. You’re addressing flooding.” – Adel Hagekhalil, assistant director of the Los Angeles sanitation bureau.
Over four years ago, a proposal for a parcel fee would have raised approximately $290 million a year for regional programs to capture and clean up stormwater quality. However, opposition from residents, businesses and schools caused L.A. County to scrap it. Looking towards the future with the board’s new liberal supermajority we can expect to see a revised proposal that would provide funding for stormwater capture projects that do more than just increase local groundwater supplies.
“A 2016 study prepared by county and federal agencies concluded that an array of projects — such as building new spreading grounds and installing infiltration swales on parkway medians – could significantly boost stormwater collection.”
We invite you to take a closer look at a green street project in action. Our MaxWell® Plus system, on the Laurel Canyon Boulevard project, is featured in this Los Angeles Times article here.
Laurel Canyon Boulevard project
The $3 million project in Pacoima is one of several projects Los Angeles is undertaking to increase stormwater capture in the San Fernando Valley. The green streets project will collect urban runoff from 123 acres, including roads and a middle school campus.
1 Runoff is directed to an underground, concrete intake chamber.
2 After the first filtration, runoff flows to the next chamber.
3 Deeper intake chamber filters water a second time as it percolates into the ground.
In our words…the MaxWell® Plus
During the pre-treatment process, this design traps out suspended solids and debris, and wicks away petroleum-based organic compounds from the inflow. Both chambers are equipped with hydrocarbon capture pillows filled with unique polymer beads, which capture a wide range of hydrocarbons and liquid organic compounds.

It’s no secret that California is at a pivotal moment in their water crisis. Practical solutions begin with drywells. Not only are drywells a small footprint stormwater management solution, they come with an affordable price tag and improve a projects capacity for aquifer recharge. Torrent is ready to help California take the first steps in the right direction towards sustainable water supplies – are you?
Whether you’re familiar or unfamiliar with our products, we can provide a free Lunch & Learn that demonstrates the power of our systems and gives insight on how to include them on your next project. MaxWell® has been outperforming other drywells for over 44 years. Learn more about the history of the MaxWell here.
