Last year the Town contracted with American Engineering Consultants to perform  the sewer system modeling and capital improvements program.  This involved field investigations and condition assessment of the system.  American Engineering conducted monitoring to establish wet weather and summer peaking factors to be used in the hydraulic model calculation.  This involved installing data loggers in all 13 lift stations.  Monitoring took place over 6 months.  A hydraulic model of the system was created using GIS data obtained from the Town.    Using field evaluations and the hydraulic model, American Engineering created a list of critical sewer system areas and improvement recommendations.

After consulting with the engineers about the collection system and issues identified, a sewer tap moratorium was issued in March 2021.  In April 2021, American Engineering presented their findings and recommended solutions for the sewer system. 

Phase I of the proposed recommendations include:

  • Upgrade Pump Stations A and B with larger pumps (keep centrifugal type pumps)
  • New Variable Frequency Drives and Controls at both pump stations
  • No new forcemain to be installed – no easements or construction outside of pump station required – Short Construction Duration

This recommendation provides approximately 70 Residential Equivalent Units (taps) each added to Pump Station A and  Pump Station B and approximately 80 Residential Equivalent Units added to Pump Station C over the number of current connections.

The project cost $860,000.

The upgrades to Lift Station B have begun.  The contractor has been doing site prep and permitting. 

Project Update Lift Station A and B Upgrades
Wednesday, July 13, 2022

On July 13, 2022, Council awarded Bid 21-028 for Upgrades to Pump Station B to AAA Utility and Construction in the amount of $747,500.  Five hundred thousand will be funded by a Rural Infrastructure Authority grant and the remainder will be funded through renewal and replacement. The project is scheduled to begin December 2022.

Project Update June 2, 2022
Thursday, June 2, 2022

Due to the unexpected escalation in the cost of construction, the Town in coordination with the consultant requested revision of the South Carolina Rural Infrastructure Authority (RIA) grant application from Upgrades to Lift Stations A and B to Upgrade to Pump Station B only. This was approved and the project is out for bid. The bids are due June 22, 2022. This allows the Town to use the $500,000 grant rather than relinquishing it because of funding.

The RIA was issued one-time time funding of $900M which the Town plans to apply for the Upgrade of Lift Station A, the force main upgrades/Phase II and automatic reading meters. The maximum grant amount under this issuance is $10,000,000.

Project Bid
