On June 24, 2013, Mount Pleasant Waterworks Commissioners approved a 7.5% increase in water and wastewater Basic Facility Charges (BFC) and volumetric rates effective with bills rendered on or after July 1, 2013.

Due to rising costs to renew overall infrastructure, change in demand projections, and overall cost of adhering to stringent Federal Regulations, this rate increase is necessary.

MPW's total asset value, which includes our water and wastewater infrastructure, is about $350,000,000. For MPW to continue providing quality water and wastewater service it must maintain and renew aging infrastructure.

Major capital projects for Fiscal Year 2014 include:

Center Street Wastewater Treatment Plant Capacity Enhancement Project $13.3M - The Center Street Wastewater Treatment Plant (CSWWTP) was constructed in 1969 and upgraded in 1986. The capacity enhancement project will upgrade the CSWWTP to meet more stringent discharge limits while achieving a 20% reduction in energy consumption by replacing outdated equipment and processes. The total project will cost $27.3 and is anticipated to be completed in 2015.

Wastewater Collection System Rehabilitation Project $2.3M - MPW's wastewater system began operating in 1942 with an untreated discharge to the Charleston Harbor and while the overall collection system is in good shape, the Old Village area contains the oldest wastewater lines in Mount Pleasant. The wastewater lines are generally over 50 years old and are primarily vitrified clay pipe, not modern plastic pipe materials. Due to cracks, breaks, and sags many of the pipes are not functioning properly, MPW will be rehabilitating the wastewater collection system in the Old Village over the next few years.

Waterline Replacement Project $1.3M - The water system serving the Old Village area was installed in the 1930's and 1940's. Some waterlines do not provide adequate fire flow protection and lines have lost capacity due to tuberculation. MPW developed a Master Plan to replace these old undersized metal pipes in that have become tuberculated, resulting in discolored water and low water pressure.

In addition to the capital projects, the Commissioners approved ending the $3 per month / per Residential Equivalent Unit Highway 17 Special Assessment.
