Weed Street Lift Station - City of St. Marys, Georgia
St. Marys, Georgia - A failure in the only gravity sewer main serving the City of St. Marys' Weed Street Wastewater Treatment Facility forced the City staff into emergency action. Instead of rushing to replace the failed pipe, the City decided to review all the options. Since the City is planning to abandon the plant in the next five years, a new lift station would eventually be needed in order to divert the flows to the City's main treatment plant. With a quote from a contractor to make repairs to the existing sewer main at over $300k, the City decided to have a new lift station designed and installed that would handle the 0.75 MGD flows currently received by the Weed Street WTP. ACC was chosen to provide design and construction documents for the new lift station. The new station was designed to serve the immediate needs of pumping to the existing treatment plant as well as the future plans for plant abandonment and discharge towards the Point Peter Wastewater Treatment Facility.
S.R. 40 Water Main Improvements - City of St. Marys, Georgia
St. Marys, Georgia - As part of the improvements identified in the City of St. Marys' Water and Wastewater Master Plan, several projects were planned to improve water quality and quantity to the downtown area. A major part of those improvements included a new 12-inch water main from Douglas Drive to the historic downtown area. The goal of the proposed six miles of water main was to provide improved fire protection and domestic water service for the populous in the central and eastern portions of St. Marys. ACC was chosen to provide all design, permitting, and construction documents for the $4 million project. The conceptual design challenges included selecting a route that would meet the project needs while minimizing impacts on the existing infrastructure, businesses and the historic district. The design included permitting extensions with Georgia DOT as well as proposed extensions along the existing St. Marys' railroad.
Lift Station 6 Improvements - City of St. Marys, Georgia
St. Marys, Georgia - ACC provided engineering services for a key lift station in the City of St. Marys' collection system that needed improvements due to its age and condition. City staff was spending many hours manning the station with temporary pumps during down times. The lift station was identified to be upgraded to handle more capacity and have the force main discharge to a proposed new lift station. However, due to the condition of the existing lift station, the improvements could not wait for the future new lift station. The design team planned a new 550 GPM submersible pump station to be built next to the existing lift station. The design accounted for current capacity with discharge to the existing force main, as well as future capacity with discharge to a future re-routed force main.
Lift Station 13 Improvements and Force Main Re-routing - City of St. Marys, Georgia
St. Marys, Georgia - In order to better serve the growing infrastructure needs of the surrounding population, the City of St. Marys needed to make necessary modifications to Lift Station 13 as defined in their Water and Wastewater Master Plan. ACC provided services to upgrade the capacity of Lift Station 13 with two 1,000 GPM pumps, construct a new wet well and re-route a force main from the lift station to a new gravity sewer influent to Lift Station 29. Engineers prepared design drawings, specifications, bidding and contract documents to construct the improvements to the Lift Station 13. They provided preliminary engineering drawings to establish both Lift Station 13 and 6 operating parameters given the programmed modifications. Services were provided from the preliminary engineering through construction administration.
