Title
Consider and take action on a resolution adopting the City of League City’s 2024 Updated 5-Year Water Conservation Plan (Director of Public Works)
Background:
Approval of this item complies with the Texas Commission on Environmental Quality's (TCEQ) requirement to update the City’s Water Conservation Plan every five years. Rules for governing development of water conservation plans for public water suppliers are contained in Title 30, Part 1, Chapter 288, Subchapter A, and Rule 288.2 of the Texas Administrative Code. This proposed update represents water conservation activities from 2019 through 2023. This information is included in the attached plan and provides further definition of the plan’s content. The 2024 plan itself has minimal changes but does update 5-year performance indicators.
Key points of this plan are as follows:
Objectives of this Water Conservation Plan
• To reduce water consumption from the levels that would prevail without conservation efforts
• To reduce the loss and waste of water
• To improve efficiency in the use of water
• To encourage efficient outdoor water use
• To document the level of recycling and reuse in the water supply
• To extend the life of current water supplies by reducing the rate of growth in demand
Under the 2019 through 2023 plan the following objectives were achieved or are ongoing
• Five-year average Per Capita Municipal Use was reduced from 115 gpcd to 108 gpcd, meeting the projected 2023 reduction goal
• Continued efforts to expand outreach efforts, that includes a water conservation mascot, Captain H2O, who accompanies the conservation team to local schools, daycares, public events, and utility-oriented training even
• The Dallas Salmon WWTP continues to provide Type 2 Reuse effluent for irrigation and produces 80 million to 200 million gallons annually
• Implemented successful Rain Barrel and Rebate Program selling 1,571 rain barrel kits and providing $11,675 in rebates during this time period
• Implemented increasing block water rates to encourage efficient large volume irrigation strategies
• Residential Toilet Replacement Program - Consideration of implementing ultra-low flow toilet (ULFT) replacement rebate program, primarily targeting homes built prior to 1995 - City staff implemented Rebate Program in 2021 which has resulted in 263 toilets totaling $16,503 in rebates over the 5-year period of 2019 - 2023
• 5-Year Average Water-Loss Percentage for 2019 - 2023 is 6 percent versus the prior 5-year period of 2014 - 2018 which was 12 percent
Potential Future Conservation Programs
• Landscape Water Conservation Measures - Consideration of mandatory twice per week year-round or seasonal watering
• Showerhead, Aerator, and Toilet Flapper Retrofit Program - Replacing old showerheads, kitchen and bathroom faucet aerators, and toilet flappers with newer more efficient models can achieve meaningful water savings
• Landscape Ordinances - Consideration to review and recommend changes to current ordinances that enhance water use efficacies
• Landscape and Irrigation System Incentives - Consideration of implementing landscape replacement programs and various irrigation system incentives
• Advanced Community Engagement - Consideration to engage the development and HOA community and free seminars
• Irrigation Design Criteria - Develop or revise design criteria to align with best management practices implemented in future irrigation incentive program
• Advanced Leak Detection and Repair - Consideration to contract advance leak detection technologies for a city-wide water loss evaluation
