Abstract:

Ground water in southern portions of the Ogallala Aquifer has declined significantly over the past several years. Attempts to recharge playa water in the past have failed due to the clogging of pits or wells by the fine playa bottom material suspended in the water. Utilizing filter underdrain systems, researchers at Texas Tech University have demonstrated that a gravity-driven artificial recharge system is feasible. Studies of alternative system designs have been evaluated and a recommended design developed. Water quality studies indicate that the quality of the recharge water produced is generally good. Operational problems have been encountered.
