Ranney Collector Well Services - Surface Water Intakes

Where the local geology does not provide suitable aquifers, where groundwater supplies are insufficient to meet your needs, or where a surface water supply is preferred, Ranney can also construct a variety of surface water intake designs to meet your needs.  These intakes have ranged in capacity from several thousand gallons per minute (gpm) to over 150,000 gpm including intakes constructed in alluvial and cohesive soils, bedrock and mixed-facies conditions. 

The fixed-screen surface water intake design we specialize in contains almost no moving parts so that O&M costs are extremely low.    The specialized construction techniques use largely trenchless technology for sinking/building the reinforced concrete caisson that serves as the wet well pumping station, and for installing the intake line(s) that deliver water from the surface water source into the caisson.  The intake screens are positioned and designed for optimum fish protection and for hydraulic efficiency to minimize plugging and to facilitate self-cleaning where possible.  Automated backwash systems complement this design to ensure the screens remain open.   Due to the trenchless methods used, disturbance is minimized during construction and operation, often simplifying the permitting process.
