Century Oaks area water main improvements
In coordination with the City of North Charleston's Century Oaks revitalization project, Charleston Water System is replacing water mains in the area, many of which predate 1941. The improvements will cost an estimated $168,000, and will be completed by Anson construction in coordination with North Charleston.

Water main and sewer force main in Byrnes Down
Charleston Water System is replacing a 16-inch water main and sewer force main in the Croghan Greenway near Byrnes Down. Both lines are on raised pilings over the wetlands, and deterioration was discovered in some pilings. The board approved a $90,000 engineering services contract in July 2006 with BP Barber & Associates; construction is estimated to cost $550,000.

Union Heights Water Main Improvements, Phase I
The current water distribution infrastructure in the Union Heights area is inadequate and new lines will provide better fire protection and system reliability. In July 2006, the Board approved a $75,000 engineering contract to Atlantic South Consulting Services. The preliminary construction estimate is $486,000. The project will be completed in three Phases:

• Phase I is from Kingsworth Avenue to Groveland Avenue
• Phase II is from Forest Avenue to Comstock Avenue
• Phase III is from Beech Avenue to Hampton Avenue.

Hollywood-Ravenel water transmission main improvements, phase I
To improve reliability and help meet growth demands in Ravenel, Charleston Water is planning to extend two 16-inch water mains in Hollywood and Ravenel. JJG, Inc. was awarded a $510,000 engineering services contract for the project, which includes $295,000 for the purchase of land and easements. The preliminary construction estimate is $1.4 million.

Replacement of 24-inch water main under Stono River to Johns Island
In April 2006, a barge damaged the 24-inch water main on the riverbed of the Stono River, making replacement of the main a more immediate priority. The Board approved a $430,000 engineering contract with HGBD, Inc. to design a replacement main to be directionally drilled under the riverbed. The preliminary construction estimate is $5.66 million.

54-inch and 36-inch water transmission mains
Two new large transmission mains are necessary to meet the increasing demand for water service throughout Charleston Water System's service area. The 54-inch main will parallel the existing 48-inch main from the Hanahan Plant to Sumner Avenue; the 36-inch main will extend from Sumner Avenue to Lincoln Avenue, where it will connect to the new water main crossing the Cooper River. In May 2006, the Board approved an $850,000 engineering services contract with BP Barber & Associates.

Riverland Terrace Elevated Tank and Distribution System Improvements
Charleston Water is planning to replace the abandoned elevated tank on the municipal golf course on James Island with a new 2-million-gallon elevated tank. The tank will help improve water flow for firefighting and maintain water service in the event of a power outage that causes a loss of pumping power. In addition to the tank, Charleston Water will build new water mains to connect the tank to the water distribution system in the area. The main will be located on the golf course property and the public right-of-way.  Click here to view a map.

In May 2006, the Board approved a $1.3 million contract with Camp Dresser and McKee, Inc. for engineering services. Construction will begin in Summer 2007. The total cost of the project, including design and construction, is estimated at $10 million.

Maybank Highway sewer interceptor
To provide sewer service to areas of Johns Island inside the urban growth boundary, Charleston Water System is planning a sewer interceptor along Maybank Highway. To acquire the necessary easements and complete surveying work, the Board approved a $101,000 engineering contract with HEG Engineering.

Filter expansion and chemical storage complex
By expanding the Hanahan Water Treatment Plant's Stoney Filter Building and replacing aging filters, filter capacity will be increased to 116 million gallons per day. To improve storage of chemicals, a new bulk storage and containment area is planned. In May 2006, the Board approved a contract with Black & Veatch for engineering services in the amount of $1.686 million.

New elevated water storage tank
A new elevated tank at the Hanahan Water Treatment Plant will provide additional filter backwash capability and system surge protection. It will also help to maintain system pressure in the event of a power outage. In May 2006, the Board awarded a contract to Camp Dresser and McKee, Inc. for engineering services in the amount of $397,800.
