What We Do
Rebate-Eligible Installations & Plumbing Inspection We Perform
The BWS rebate program covers a range of water-saving upgrades — we install them all.
High-Efficiency Toilet Installation
WaterSense-certified toilets that use 1.28 gallons per flush or less qualify for BWS rebates. We remove and replace your old toilet with a qualifying model — typically saving 20–60% on toilet water use.
Low-Flow Showerhead Installation
Qualifying low-flow showerheads (2.0 GPM or less) can receive BWS rebates. We install WaterSense-certified showerheads in all bathrooms — saving thousands of gallons per year without sacrificing performance.
Smart Irrigation Controller Installation
Weather-based irrigation controllers adjust watering schedules automatically based on rainfall and evaporation. These qualify for BWS rebates and can reduce outdoor water use by 15–30%.
Leak Detection & Repair
The BWS offers rebates for fixing leaks that have caused abnormally high water bills. We document the leak, perform the repair, and provide the service records you need for your rebate application.
Water Heater Upgrade
Certain high-efficiency and heat pump water heaters qualify for utility and state rebates. We can advise on which models are currently eligible and handle the installation.
Rebate Documentation Assistance
BWS rebates require proof of purchase, contractor license information, and installation records. We provide all the paperwork you need to submit your rebate application successfully.
