Casitas is committed to providing our customers with the knowledge and resources necessary to reduce their water use and save money.

Free water surveys - Residential & Commercial 

The Water Survey Program is a free service offered to our customers to provide indoor and outdoor water-saving assistance, ultimately lowering their water bill.

Casitas offers on-site surveys for indoor and outdoor water use of single-family and multi-family residential customers  as well as for commercial customers in our service area. The indoor survey includes a test of showerhead and faucet flow rates, an estimate of toilet flush volumes, a review of all water-using appliances and a test for toilet leaks. The outdoor survey includes a review of the irrigation system, irrigation design, and watering schedules. The survey also includes reading the meter to reveal possible leaks in the customer's system. 

To schedule an appointment for your free survey, please email:
