About this file
This is a Lift Station Typical Exhibit document prepared for the West Virginia Department of Environmental Protection, Office of Special Reclamation, for the Mary Ruth Corporation under Permit 1015-88. The document provides detailed technical specifications and design parameters for a wastewater lift station facility. The lift station is designed with a 30 horsepower, 3-phase/480-volt pump capable of delivering 180 gallons per minute at 180 feet of total dynamic head. Key components include a wet well measuring 6 feet inner width by 18.88 feet depth with a top elevation of 1834.50 feet, a pig launcher and valve vault system, and multiple interconnected piping systems using HDPE SDR11 and stainless steel materials. The facility includes safety features such as a watch dog float at elevation 1820.50 feet, air relief valves, an 8-inch overflow pipe, magnetic flow meter, and ultrasonic level transmitter for monitoring. Access is provided through aluminum hatch covers and safety ladders, with floor drains and stainless steel venting systems.
The specifications require all pump components in contact with water to be constructed of stainless steel or non-corrosive materials capable of operating in pH environments between 2.8 and 3.0 standard units. The contractor may elect to construct the tank structure as either precast or cast-in-place concrete, with cast-in-place requiring certified professional engineering design and resteel calculations submitted for approval. All pipe intrusions must utilize Z-Lok or Kor-N-Seal boots, and precast pump vaults must include Polyseal or engineer-approved watertight connections on external joints supplemented with mastic seals. Backfill around the vaults consists of AASHTO #3 material compacted in two 6-inch lifts. The design plans were prepared in April 2020 and reference technical specifications for cast-in-place concrete, precast structures, cementitious crystalline additives, and manhole construction standards.
