City of San Marcos Rainwater Harvesting Rebate Program

The City of San Marcos is offering a capacity-based rainwater harvesting system rebate program just like the City of Austin. The rebate program is structured as follows:

  • $0.50 per gallon of storage capacity for non-pressurized systems (no pumps)
  • $1.00 per gallon of storage capacity for pressurized systems (with pump)
  • Total maximum lifetime rebate amount of $5,000 per site
  • All sizes of rain barrels and rainwater collection cisterns/tanks are eligible

Rebate cannot exceed 50% of total system cost. The maximum lifetime rebate amount is determined by your water meter size:

  • For 5/8 x3/4″ meters (residential) the maximum rebate is $5,000
  • For 1″ water meters the max rebate is $10,000
  • For 1.5″ water meters the max rebate is $15,000
  • For 2″ meters and larger the max rebate is $20,000

The rebate covers rainwater system components including: rainwater barrels or tanks, screened gutters, leaf screens, first-flush diverters, primary filtration systems, tank pad/foundation, pumps, and backflow devices installed at the City water meter. The rebate is not applicable to miscellaneous pipes and fittings, advanced treatment systems (for potable water), irrigation system components, maintenance agreements or warranties.
