Groundwater Conservation Plan (GCP)

Increasing water demands, extreme weather variability and mandated reductions in use make year-round conservation an important tool in managing groundwater. To improve water-use efficiency, municipal, industrial and irrigation permit holders are required to implement an individual conservation program and then document their efforts three times a year. Successful plans require implementation of Best Management Practices (BMPs)—practices proven to achieve measurable water savings.

Please check with the EAA for a list of approved BMPs. They may include, but are not limited to, the following: 

Best Management Practices

Municipal and Industrial BMPs

  • Meters on all new connections and retrofits of existing connections to account for all water usage. (Municipal)
  • Conservation pricing through quantity based pricing structures to provide economic incentives for efficient water use. (Municipal)
  • Public information and school education programs to promote water conservation awareness. (Municipal)
  • Appointment of a conservation coordinator to oversee GCP implementation and ongoing activities. (Municipal)
  • Water survey programs to track and control water usage and incentive programs for institutional, commercial, industrial and residential accounts. (Municipal)
  • Residential plumbing retrofit and rebate programs for distribution or installation of high-quality, low-flow plumbing devices and rebates for installation of high efficiency washing machines. (Municipal)
  • Reuse of available treated effluent to replace Edwards Aquifer groundwater on golf courses, in large cooling plants and other industrial or landscape processes. (Municipal
  • Prohibition of wasteful activities such as landscape watering during peak hours to non-recycling decorative water fountains. (Municipal and Industrial)
  • System water audits and leak detection and repair programs to check for unaccounted water loss exceeding 15% of total system water. (Municipal and Industrial)
  • Landscape conservation programs and incentives for non-residential and residential customers owning tracts of land. (Municipal and Industrial)
  • Cooling tower conservation to reduce the amount of makeup water needed by increasing the cycles to the maximum level possible. (Industrial)  
  • Sub-metering feasibility study on facilities or equipment comprising at least 20% of total water usage to determine the benefits of replacing mixed-use meters with dedicated landscape meters. (Industrial)

Irrigator BMPs

  • Surge flow irrigation to apply water intermittently to furrows, creating a series of on-off periods of either constant or variable time intervals and/or:
  • Installation of sprinkler systems including side-roll, center pivot and linear movement and micro-irrigation systems including drip, bubbler and micro sprinklers which use water more efficiently.
