    Hey! Tanks LA

    Scott Mathers founded and has directed Hey! Tanks LA (HTLA) since 2008. HTLA consults, designs, and installs water harvesting systems ranging from 50 to 50,000 gallons in size in Southern California.  Operating as a general contractor, HTLA has worked directly with municipalities including the cities of Los Angeles and Santa Monica, and the Los Angeles County Dept. of Health and Safety to establish guidelines, create reference documents, and implement policy on water harvesting BMPs.  By working with national non-profit organizations such as ARCSA (American Rainwater Catchment Association, arcsa.org; and local non-profits such as Tree People treepeople.org in Los Angeles, and Watershed Management Group in Tucson, AZ wmg.org, HTLA has been able to establish itself as a successful local business dedicated water harvesting to water harvesting.


    Design / Consult

    Hey! Tanks LA, has consulted California architects and contractors in planning, bidding, permitting and building larger projects requiring special design parameters.

    2012 – Konig Eizenberg Architecture Inc. contracted HTLA to consult for the City of Santa Monica Pico Branch Library.  The proposed system will flush toilets for the library; a first for the city to use captured rainwater indoors!.  The project was awarded to Konig Eizenberg.

    2012 – HTLA was contracted as a consultant to provide plans, process permits through the state and county, and design the main holding tank for a 50,000 gallon rainwater harvesting system constructed beneath a recording studio parking lot.  The system features wireless automated system controls, water supply status updates and digital reporting.  The tank was designed in response to the recent Low Impact Development policy requirements for LA County.

    2012 – State Assembly Hearing, Scott spoke on a panel as an advocate for State level investment in water harvesting policy and technology.  Scott was joined on the panel by Andy Lipkis, Tree People founder, and others defined presented to the hearing as “successful businesses in water harvesting”.

    2011 – Hey! Tanks LA (HTLA) was contracted with the City of Los Angeles to produce a video “how to install a rain barrel”.  The video was produced in response to the city’s recent rainwater harvesting incentive program.

    HTLA manufactures a Los Angeles County pre-approved modular rainwater catchment system.  These systems are required to comply with the county’s recently implemented Low Impact Development (LID) ordinance.

    Hey! Tanks LA continually assists Environmental Charter High School students to raise funds by teaching the students how to safely  and effectively construct rainwater harvesting systems using locally available materials.  The students are able to make the systems and sell them as modular pieces for fund raising.



    Operating as a general contractor, Hey! Tanks LA, installs rainwater harvesting, greywater harvesting, and hybrid systems for residences, schools, commercial buildings and public gardens throughout Los Angeles.
