Professional Engineering Services for the Sugar Creek East Equalization Basin, Pump Station, and Forcemain

The East Flow EQ Basin and Grit Facility, constructed in 1997, is located south of the treatment facility along Little Sugar Creek. During high flow events, wastewater flows south by gravity to the Excess Flow Control Chamber via a 54” line. In the Excess Flow Control Chamber, there is a gate that can direct flow to either the McAlpine Creek WWMF or to the Flow EQ Fill Pump Station. With the gate to McAlpine Creek WWMF line closed, wastewater enters the Flow EQ Fill Pump Station and is pumped to the East Fow EQ Basin for storage. Once the storm surge is complete and staff want to empty the East Flow EQ Basin, wastewater can then drain via gravity or Return Flow pumps to the Excess Flow Control Chamber, where it then flows by gravity to McAlpine Creek WWMF.

  • System Evaluation: Assess the proposed suction and discharge pipeline that will connect to the new BPS. CLTWater is awaiting modeling results from the Water Master Plan (WMP), which are expected at the end of 2025. Review the existing data, WMP, and hydraulic model to determine capacity and operational constraints.
  • Design Requirements: Utilize the existing hydraulic model to establish design criteria for the BPS. Define design flows, pressures, pump configuration, and operational parameters in coordination with the Owner.
  • Design Development: Evaluate site conditions and constraints. Assessment should include review of applicable requirements under the Unified Development Ordinance (UDO) and provide recommendations to ensure compliance. If needed for any reason, assist CLTWater in identification of a more suitable site. Prepare preliminary engineering report for review and comment to document recommendations and decisions for the BPS detailed design. Prepare detailed (30%, 60%, 90%) design documents for review and comment. Develop complete 100% design drawings and technical specifications suitable for bidding and construction. At CLTWater’s option, Proposer may be asked to design or assist in the design of sections of the associated watermain (NEWT, Phase I).
  • Permitting: Identify all applicable permits and approvals required at the federal, state, and local levels. Prepare and submit permit applications and supporting documentation. Coordinate with regulatory agencies to secure approvals.
