Water Supplies Using Infiltrated Surface Water
The Ranney® Collector Wells of Layne Christensen Company has broad
experience developing water supplies from
infiltrated surface water. We have developed these supplies using both conventional infiltration galleries
and shallow collector wells constructed to maximize the amount of infiltrated surface water.
Where geologic conditions beneath a surface water body are relatively impermeable or of insufficient
thickness and depth to support ground water extraction, an infiltration gallery can be used to develop
moderate to large quantities of water. These galleries induce infiltration from adjacent surface water
bodies. The construction procedures used are similar to those for a radial collector well when permeable
sand and gravel deposits are found. Where finer grained material exist on the river or lake bottom, the
infiltration gallery intakes can be installed in a trenches excavated in the bed of the surface water body,
or parallel to the surface water body, which are then backfilled with selected filter materials after the
intake screen installed.
Ranney® Collector Wells has experience in developing water supply
systems that specifically seek to maximize the amount of infiltrated surface water from such regions as the
Great Lakes, the Mississippi-Missouri-Ohio River Basins, the Platte River basin, the Colorado River Basin,
and the Columbia River Basin. This experience has provided our technical staff and constructors with
first-hand knowledge of construction and performance issues that are unique to the design and installation
of these systems.
