The City of Holyrood’s 3-cell sanitary treatment facility had extreme algae growth, resulting in frequent TSS violations and a schedule of compliance from KDHE. The City wanted a system that was low maintenance and would reliably meet permit. EBH determined building an additional wetlands cell to make the system non-discharging was the best way to do that. By working with City personnel, KDHE regulators, and local landowners, EBH was able to provide a long-term solution at minimal cost to the City.

Since there was no seepage limit for this wetlands cell, no clay liner was constructed. Erosion of the inside slopes is prevented by vegetation growth. The cell is designed with three different water depths to encourage a healthy ecosystem with a variety of wetlands plants.

Project Details

EBH Engineering was selected by the City of Holyrood, Kansas, to design improvements for their sewage treatment facilities. The project included the following:

  • Construction of a non-discharging wetlands cell in addition to the existing 3-cell system, construction of a treated effluent pump station and 4” PVC force main, boring under abandoned railroad, construction staking, stormwater pollution prevention plan, installation of floating aerators to reduce the sludge layer in existing cells, and seeding.
  • Existing sewer plant kept in operation at all times.
  • Electrical conduit, conductor, and breaker panels for the Treated Effluent Pump Station provided by the City.
