ACCWA Supplies “Best Practices for Homeowners” Brochures to Residents of the Aquifer Protection Overlay Zone
Approximately 400 residences and several businesses are located in the Aquifer Protection Overlay Zone (APOZ). Most of these were in place at the time the APOZ was designated; prior to that time, there was little understanding of the aquifer and how to protect it.
The APOZ encompasses properties both inside the Laramie city limits (all on city water and sewer systems), and outside the city limits (relying on domestic septic systems and water wells).
The Casper Aquifer Protection Plan was first developed in the late 1990s and last updated in 2023. Each iteration of the plan has contained a section on “Best Practices for Homeowners,” but these have never been communicated directly to APOZ residents.
ACCWA assembled the recommendations into two brochures: “Our Drinking Water” for all APOZ residents, and “You and Your Septic System/Residential Water Well Sampling and Maintenance” for APOZ residents outside the city limits.
