Water Recovery Services, Inc. (WRS) was recently awarded a Federal contract by the U.S. Fish and Wildlife Service to rehabilitate water wells at the Entiat National Fish Hatchery (ENFH) north of Wenatchee, Wash.
Two groundwater wells at the hatchery require rehabilitation and maintenance work, in addition to the installation of new 500 gallon per minute pump bowls. These large diameter screened wells have declined significantly in production due to biological plugging and physical plugging resulting from compaction of the surrounding formation around the screens.
According to Jason Reeves, the Hatchery official responsible for water well and facilities maintenance, the wells require periodic rehabilitation and maintenance to maximize well efficiency and the use of the water rights in an effort to fulfill mitigation responsibilities. Pathogen-free groundwater is used year round at the facility and is maximized for a nine-month period during peak production times.
WRS will use its patented Aqua Freed process, which utilizes gaseous and liquid carbon dioxide, to detach, dissolve and remove sediment and mineral encrustations from the well’s screen surfaces and the surrounding aquifer.
Hatchery Officials stated that various other well treatment techniques and vendors have been used at the ENFH in the past with poor results. The Aqua Freed process is a proven, trusted and cost-effective method of rehabilitating and maintaining ground water wells at this facility.
Water Recovery Services, Inc. has cleaned and restored hundreds of wells throughout the Inland Northwest since 1996. They provide water well and system services for industrial, municipal and residential clients throughout the states of Washington and Idaho and are the sole providers of the patented Aqua Freed water well rehabilitation process which safely and economically restores water quality and quantity to wells. Wells, which in the past had to be deepened or replaced, can now be rehabilitated in days at a fraction of their replacement cost. This has proven time and again to be the quickest and most economical means of obtaining more well water.
