Monitor water use and detect leaks in real time with a flow sensor. Protect your property from costly water damage and conserve water with a SAWS rebate.

How It Works

In response to the ongoing COVID-19 pandemic, the SAWS Annual Irrigation Checkup deadline has been extended to June 1, 2021 and is subject to change, if needed. For all inquiries, please contact SAWS Conservation at 210-233-3443 or email

  • STEP 1: Complete an Annual Irrigation Checkup (If required)

    Per City of San Antonio Ordinance, residential and commercial properties five (5) acres or larger and properties defined as Large Use (properties that used over 1 million gallons of water for irrigation in the prior calendar year) with in-ground irrigation systems submit an annual irrigation checkup to the San Antonio Water System Conservation department by May 1 each year. Properties not in compliance with this step will not be eligible for a rebate until compliance requirements are met.

  • STEP 2: Before You Buy

    Determine if your property is eligible and Wi-Fi is available, then review the rebate agreement and research the SAWS-approved devices. These products may be installed on up to two-inch meters.

  • Buy and Install

    Purchase an approved product at any retail location. One flow sensor is self-install while other devices may require a plumber.

  • STEP 3: Apply for $150 Rebate

    Submit a rebate application. After SAWS verifies the device was activated at the account's location, the rebate will be applied as a credit on the account. Program funds are limited and applications will be processed on a first-come, first-served basis.

Before You Buy


Smart water monitoring systems are relatively recent innovations. They can help you identify leaks and track your water use, potentially saving you money and avoiding property damage or unexpected high water bills. Research each device’s features and costs carefully before selecting a product.


Are you Eligible?

Do Your Homework

Research each product before purchasing a device to ensure it meets your needs.

  • Visit each product website and determine the cost of installation.
  • Watch the installation videos provided by the vendor.
  • Some products measure indoor water use only while others record water consumption at the meter, including outdoor watering. Note: Only the Flume device measures both indoor and irrigation system water consumption.
  • Flume Flow Sensors may not be installed on meters in the ConnectH2O pilot program​. If you are unsure whether the meter at your property is part of the program, call us at 210-704-SAWS (7297).
