Rebate Boundaries

Collecting rainwater and using low flow fixtures are just a couple of ways that you can do your part to conserve our local natural resources. One inch of rain on one thousand square feet of roof can generate six hundred gallons of water that can be put to all sorts of outdoor use. While replacing conventional fixtures in your home with those that are low flow could save 2,900 gallons per shower head, and 13,000 gallons per toilet, per year in the average american household. For these reasons, we have partnered with several districts within the Stanislaus and Tuolumne River watersheds to provide rebates for rainwater systems and low flow fixtures.


Rainwater Catchment Rebate

Homeowners within the T-Stan IRWMA boundary (all of Tuolumne County, and up to  Hwy 4 in Calaveras County), who install working rainwater catchment systems may be reimbersed for a portion of their costs at a rate of 30 cents per gallon of their tank capacity.

To qualify, homeowners must submit the following to

  • Pictures of their installed rainwater catchment system

  • All available receipts pertaining to the project

  • A short written description of their rainwater catchment system including, system capacity, materials used, and time spent to complete the project.

Please fill out and send to Lindsay Mattos at with appropriate pictures and receipts. 

Watersense Toilet and Showerhead Rebate

Home owners within the above boundary can now receive reimbursement of up to $100.00 for one Watersense labeled toilet, and up to $25.00 for one Watersense labeled shower head.  Shown below is the Watersense label given to products proven to meet the EPA's efficiency standards and is easily visible on most products
