CUSTOMERS WATER WASTEWATER DEVELOPMENT PROGRAM CAPITAL PROGRAM ABOUT US BIDS WATER SOURCE WHERE DOES YOUR WATER COME FROM? Mount Pleasant Waterworks has two water sources, groundwater from the Charleston Aquifer (also known as Middendorf Aquifer) and purchased surface water from Charleston Water System. Source 1: Groundwater Your water comes from the Charleston Aquifer, a pristine groundwater source estimated to be more than 50,000 years old. Six wells are drilled at an average of 2,000 feet below the earth’s surface and raw water is pumped to four Reverse Osmosis treatment plants and disinfected with chloramines. Source 2: Purchased Surface Water MPW has a wholesale contract with Charleston Water System to purchase treated surface water to help satisfy the water demand in our service area. Drinking water is sourced from the Bushy Park Reservoir and the Edisto River, treated by conventional water treatment, and disinfected with chloramines.

CUSTOMERS WATER WASTEWATER DEVELOPMENT PROGRAM CAPITAL PROGRAM ABOUT US BIDS DISTRIBUTION SYSTEM Drinking water is delivered to homes and businesses through the water distribution system, a network of infrastructure that includes pipes, valves, fire hydrants, treatment facilities, and storage tanks. Mount Pleasant Waterworks’ water mains must be maintained to ensure the water keeps flowing 24 hours a day, 365 days a year. Fire Hydrants Fire hydrants are owned and maintained by Mount Pleasant Waterworks, although area fire departments periodically test hydrants. Mount Pleasant Waterworks has more than 5,000 fire hydrants. We do allow fire hydrants to be used for temporary water service, but this requires a special permit. Submit a permit or meter request here (need hyperlink to form page form already exist). Water Main Flushing Over time, minerals and other deposits can accumulate inside water mains. To clean the mains and remove these deposits, Mount Pleasant Waterworks’ uses a technique called Unidirectional Flushing, or UDF. Flushing water mains involves opening a nearby fire hydrant and discharging water from the hydrant; the high velocity of the water cleans the inside of the mains. Following this flushing you may experience discolored water, run your faucets until your water clears.
