Sediment Removal Augusta, GA

From Sediment Removal to Siphon Systems and Pond Liners

  • Pressure Grouting: A process of pumping grout through existing pipes running through the dam, that seals voids and spaces in order to terminate use of the pipe.

  • Pipe Slip Lining: A process of inserting a new pipe into an old horizontal pipe. The surrounding area between the two pipes is pressure grouted to prevent seepage through voids in the old pipe.

  • Plunge Pools: An area below a siphon system of other spillway, that is stabilized (usually with concrete or rock) in order to dissipate water flow energy for the purpose of minimizing erosion.

  • Siphon Systems: Primary spillway consisting of a pipe running with the contour of the dam, and capable of moving high volumes of water when under vacuum. Systems may be permanent or temporary. Permanent lines are usually encased in concrete and go through the dam. Temporary lines are usually placed above ground, on top of the dam.

  • Wellpoint System: System that drains water from existing ground in order to install clay cores.

  • Toe Drains: Drains (consisting of rock, sand, pipe, and filter fabric) along the bottom of the back side of the dam, that collect excess seepage from the bottom of the dam and transport water through the pipes to desired areas.
      
  • Chimney Drains: Vertical drains (consisting of rock, sand, pipe, and filter fabric) along the backside of the dam, that collect excess seepage from the dam starting at normal water pool elevation all the way down to the bottom of the dam.
      
  • Drop Spillways: Concrete or steel structures/ walls, where the top of the structure is equal to normal water pool elevation, over which water flows and is dissipated into a plunge pool area.

  • Wet Well Systems: Consists of horizontal pipes running from ponds at the underground level and then connected to a large vertical pipe. Inside the vertical pipe, pumps may be placed that allow for pumping cool water out of the pond for irrigation, etc.

  • Duck Ponds: Ponds equipped with an adequate draining system so that they can be drained during the summer in order to plant vegetation.

  • Wetlands Enhancement: Restoring or creating an area with various types of trees and grass to encourage wildlife habitation and natural filtering for water.

  • Kaolin Lining: Hauling and placing an impervious clay so that a pond might be attainable in an area that would otherwise not hold water.
