<br />Hays, Kansas, to Use Reclaimed Waste Water for
<br />Groundwater Recharge
<br />
<br />The Smoky Hill Project, sponsored by the City of Hays, Kansas, was
<br />originally planned to use water from the Bureau of Reclamation's Cedar
<br />Bluff Reservoir to recharge the city's well fields in the Smoky Hill River.
<br />Cedar Bluff water recently became unavailable to the city because of
<br />upstream depletions and reallocation of the reservoir yield to fish, wildlife,
<br />and recreation purposes, With the City of Hays currently under severe water
<br />use restrictions, the city has turned to waste water reuse as a way to meet
<br />critical current and near-term water requirements,
<br />
<br />Working with the Bureau of Reclamation, the city has redesigned the
<br />recharge project and included it as part of an overall water management
<br />program, The project will henceforth be known as the Big Creek Water
<br />Banking Project and will involve reusing the city's sewage effluent for
<br />recharging the Big Creek Aquifer, The project will include installation of
<br />new wells to recapture the effluent water that is recharged through the Big
<br />Creek sand bed. The project will also evaluate the use of wetlands as a [mal
<br />water treatment step to "polish" the water prior to recharge.
<br />
<br />The Kansas State Division of Water Resources and the Department of
<br />Health and Environment are working with the city to approve the project.
<br />The project could break new ground in several legal and institutional areas.
<br />Water rights and well contamination issues will be addressed. Legal and
<br />institutional issues, if they can be solved, could lead to more efficient
<br />administration and use of surface and groundwater resources throughout
<br />Kansas.
<br />

<br />
<br />The project will be developed in two phases, with conceptual designs,
<br />environmental clearances and base line monitoring to be conducted first,
<br />followed by construction and verification in the field.

<br />Groundwater Recharge Needed in the Pacific Northwest
<br />
<br />A Seattle Water Department's study
<br />of its production well field in the
<br />Highline area indicates that
<br />groundwater withdrawal in excess of
<br />6 mgd to 8 mgd for 4 months would
<br />result in a long-term decline of up to
<br />2 feet per year in the groundwater
<br />
<br />level. Studies have shown that the
<br />groundwater level decline could be
<br />stabilized by injection of recharge
<br />water during the off-peak season.
<br />
<br />Under the High Plains States
<br />Groundwater Demonstration
<br />
<br />August 1990
<br />
<br />
<br />Highline well field, Seanle - drilling 10
<br />determine extent of aquifer.
<br />
<br />Program, the city's initial effort will
<br />be to estimate the effects of recharge
<br />water on the quality of the aquifer
<br />water and on the hydraulic
<br />performance of the aquifers due to
<br />water-mineral interaction, degassing,
<br />or increases in biota, Testing will be
<br />performed to evaluate the chemical
<br />changes that may occur during
<br />mixing of surface and groundwater
<br />and the interaction of the mixed
<br />waters with the aquifer material.
<br />Mitigating measures may be required
<br />if chemical changes occur due to the
<br />mixing and interaction of recharge
<br />water and groundwater.
