Clarke Creek Pumping Station and Forcemain Progressive Design Build Project

Charlotte Water (CLTWater) treats raw water drawn from the Catawba River Basin and distributes treated drinking water to customers within Mecklenburg County and surrounding regions.   Wastewater generated from consumptive use in eastern Mecklenburg County is discharged into the Rocky River Basin via two wastewater treatment plants (WWTPs). CLTWater intends to offset some wastewater flows that are currently tributary to the Rocky River basin due to transfer constraints and limited treatment capacities.

This Progressive Design-Build (PDB) project will likely involve the construction of at least one pumping station and force main to transfer flows from east Mecklenburg county to a wastewater treatment plant within the Catawba River Basin. Gravity sewer improvements may be necessary on the receiving sewer.  The PDB firm will be required to analyze options for pumping to minimize or eliminate receiving sewer improvements. The Firm will need to consider options for storage at the pumping station or elsewhere in the system to achieve this goal.

The total anticipated CIP budget for this project is approximately $45M, assuming forcemain and gravity sewer improvements will be sized without EQ storage. The budget will vary depending on storage needs. A phased approach for the mentioned improvements, considering future connections to transfer additional flows, will be necessary to align with CIP funding schedules. CLTWater intends to have the initial project phase completed and activated to offset partial flows within two years of the notice to proceed for the planning and design work.

The PDB Team will need to have all the necessary resources to complete the planning, design, permitting, easement acquisition, and construction of this project.

FY22 Small Diameter Water/Sewer Service Contract

This contract is for water and sanitary sewer service installations including connection to the existing public main, which extends a small diameter line to the property, and includes a water meter box or sanitary sewer cleanout. Customers pay connection fees for the installation service, which is based on costs incurred by Charlotte Water in these contracts. The work covered by this contract will provide approximately 400 total services.

Linda Lake/Oakwood Pond Rehabilitation Project

Work includes removing trees and vegetation from the two dams, lowering the water surface at Linda Lake Dam and cleaning and inspecting the spill way as well as making any necessary repairs to the joints of the spill way.  Refreshing rip rap where needed on the dam embankments.  Installing piezometers at Linda Lake, and testing the operation of the bottom drains of the two lakes.

Collective Series J Storm Drain Improvement Project

The Collective Storm Drainage Improvement Project (SDIP) Series J contains three separate projects which vary in size and each bring their unique differences. The work involves various storm drainage improvements including replacement of storm drainage pipes, culvert, masonry drainage structures, water line, sewer line, asphalt pavement, concrete driveways, concrete sidewalk and concrete curb. These improvements will realign storm drainage to reduce structure flooding and address failing infrastructure. Due to the complexity of these projects and their proximity to utility poles/structures/retaining walls, active shoring will be required.

Collective Series K Storm Drainage Improvement Project

The purpose and need for this construction project is to improve the storm drainage infrastructure (i.e. pipe systems and culverts) to reduce flooding and to enhance degraded stream reaches to reduce erosion and improve water quality.  This project is a collective package of three small storm drain improvement projects that will be constructed under one contract.  This project package is under review and location and project details will be provided after review is complete.
