In the Laramie area, the Casper Aquifer supplies approximately 60% of the City's drinking water and 100% to those homeowners that fall within the Casper Aquifer recharge area. The community has noted the importance of the Casper Aquifer. Since 2002, the community has relied on the Casper Aquifer Protection Plan and accompanying ordinance to protect our water supply.
