Residential Irrigation Design Rebate

Make your irrigation system more efficient and receive a maximum $800 rebate to help cover the cost.

Through our Residential Irrigation Design Rebate, SAWS conservation consultants will work with your irrigator to help identify design flaws in your irrigation system that, if changed, can result in both water savings and healthier landscapes.

Who is Eligible?

Existing residential customers who receive water service from San Antonio Water System. For information on our commercial irrigation rebates, click here.

Terms of the Rebate:

Up to $800 for any combination of options, depending on the number of zones converted or capped, and if irrigation remains at or below a personalized schedule for water use over a one-year period. Only existing systems are eligible for rebates.

All customers approved to receive the first installment of their rebate will be given the final installment if they meet the water use requirements, even if the program is discontinued prior to the final rebate installment.

How it Works: In Four Steps

STEP 1:  SAWS customers must call 210-704-SAVE to schedule an irrigation consultation with one of our trained conservation consultants before any irrigation work you want a rebate for begins. Appointments are scheduled on a first-come, first-served basis. It is recommended you call at least 2-3 weeks in advance of any planned work for an appointment. Appointments generally last an hour.

Consultants will run through your irrigation system, review your landscape and conservation goals, make recommendations specific to your home and leave you with written recommendations you can use when hiring an irrigator.

STEP 2:  Have a licensed irrigator complete the work or you may complete it yourself. If you complete the work yourself, you must follow all city and state laws governing irrigation installation and design.

STEP 3:  Once the installation of the redesigned system has been completed, call 210-704-SAVE to schedule a final inspection. Your conservation consultant will conduct a final inspection, including work completed and irrigation controller scheduling.

The consultant will then determine the amount of the rebate you may qualify for and provide you with a written copy. This will serve as your application for the Residential Irrigation Design Rebate. Upon final inspection and application approval, SAWS will credit your water bill with the initial installment of 50 percent of the total approved rebate.

STEP 4:  If your water use remains at or below the watering recommendations for a period of one year, the final installment of the remaining 50 percent of the eligible rebate will be applied to your account.

You will receive monthly recommendations based on your unique property so you may compare actual water use to SAWS recommendations, which are based on actual weather conditions including any restrictions.

What is Eligible?

The following may be done on each zone of your system, but the maximum total rebate payment per property is $800.

Irrigation Design Rebate
Amount Procedure Description
$450 Disabling entire system The removal of the backflow device, backflow box, all valve boxes and the controller; cutting the "T" connection and capping snugly to the mainline.
$250 Capping a zone The removal and capping of an existing zone valve.
  • This might be chosen because an area is now hardscape, has been converted to bedding area instead of turf, or because the plants are mature and do not require regular irrigation.
$200 Converting a pop-up spray zone to drip/bubblers

The conversion of a zone that is currently irrigated by a pop-up spray or rotor irrigation system.

  • Drip system pop-up spray must include appropriate pressure regulation, a filter and pressure release valve.
  • For conversion from fixed sprays and rotors to a drip system, emitters must not exceed 1 gallon per hour.
  • Drip irrigation must consist of: (1.) Half-inch tubing with built-in emitters; or (2.) Smaller point-source tubing connected laterally with individual emitters for specific plants. Tubing with laser holes is not eligible for rebate.
  • Fittings should not be the barbed connection fittings but compression fittings that are more secure.
  • System must include: (1.) A pop-up head with its nozzle closed or capped and the stem painted a bright color; or (2.) A manufactured flag indicator. This will indicate that the zone is working properly. Misters are not allowed.
  • Bubblers must be nonadjustable, fixed flow - not to exceed 1 gallon/minute per head.
$150 Splitting a zone to beds and turf Conversion of a single zone that covers both turf and beds to two separate zones for turf and beds.
