Septic System Projects

Kroger

  • The sewage system for the Kroger store is designed to serve the food store, deli and staff offices. The design flow for this system is 2,000 gallons/day
  • The flow estimation for this system, as determined by the Virginia Department of Health (VDH), was based on flow records from existing facilities. Removal of solids is accomplished by a 1500-gallon septic tank. Two 1,000-gallon grease traps on the gravity line from the deli separate grease from the deli’s effluent. After passing through the septic tanks (and grease trap if necessary), the effluent flows by gravity into a High Strength Fast 4.5 secondary treatment unit. The effluent is then treated and flows to the 5,750-gallon pump chamber. The pump chamber is equipped with a duplex submersible pump system that is activated by floats. As the effluent level rises in the pump chamber, the pump ON float starts the pump. The water level will recede to just below the pump OFF float, which shuts off the pump. The system is also equipped with an ALARM float, which activates an audible/visual alarm located inside the building if the effluent rises more than 6″ above the pump ON level without the pump starting.
  • Sewage effluent is pumped to four separate drainfields. The effluent travels from the pump chamber through approximately 1,700 linear feet of 2-inch force main to a pressure manifold for distribution into the four separate drainfields. The pressure manifold is designed to operate at approximately 2 pounds per square inch. The pumps are rated at 41 gallons/minute at 43.2 feet of Total Dynamic Head for the four drainfields. A 2.5-acre area within and down gradient of the drainfields has been designated as a nitrate dilution area. The entire system has been designated by the VDH as Reliability Class III, as stipulated in the Commonwealth of Virginia Sewage Regulations (12 VAC5-581).

Wendy’s Westlake Towne CenterWendys 1

  • The Wendy’s sewage system is located on State Rt. 122 in Franklin County, Virginia
  • The sewage system for the Wendy’s restaurant is designed to serve 94 seats. The design flow for this system is 1,800 gallons/day
  • The flow estimation for this system, as determined by the Virginia Department of Health (VDH), was based on flow records from existing facilities. Removal of solids is accomplished by a 1500-gallon septic tank. A 1,000-gallon grease trap on the gravity line separates grease from the restaurant’s effluent. After passing through the septic tanks (and grease trap if necessary), the effluent flows by gravity into a High Strength Fast 4.5 secondary treatment unit. The effluent is then treated and flows to the 4,150-gallon pump chamber. The pump chamber is equipped with a duplex submersible pump system that is activated by floats. As the effluent level rises in the pump chamber, the pump ON float starts the pump (refer to Figure 3 in Appendix C for diagram). The water level will recede to just below the pump OFF float, which shuts off the pump. The system is also equipped with an ALARM float, which activates an audible/visual alarm located inside the building if the effluent rises more than 6″ above the pump ON level without the pump starting.
  • Sewage effluent is pumped to four separate drainfields. The effluent travels from the pump chamber through approximately 2,365 linear feet of 2-inch force main to a pressure manifold for distribution into the four separate drainfields. The pressure manifold is designed to operate at approximately 2 pounds per square inch. The pumps are rated at 42 gallons/minute at 40.5 feet of Total Dynamic Head for the four drainfields. A 2.21-acre area within and down gradient of the drainfields has been designated as a nitrate dilution area. The entire system has been designated by the VDH as Reliability Class III, as stipulated in the Commonwealth of Virginia Sewage Regulations (12 VAC5-581).
