CTDEP - Potable Water Treatment
Client: Connecticut Department of Environmental
Location: Hartford, Connecticut
Project: Potable Water Treatment Contract for Residential and Commercial
Contaminated Drinking Water.
DES was awarded a contract by the State of Connecticut's Department of
Environmental Protection (CTDEP) in 1996 to engineer, install, and maintain
treatment systems capable of treating contaminated potable water in residential,
commercial, and industrial establishments. Since the contract award, DES has
installed and serviced more than 500 water treatment systems for the CTDEP.
All treatment systems designed and installed under this contract meet the
strict requirements of the CTDEP and Connecticut Department of Public Health.
Most systems include Granular Activated Carbon (GAC) filters for the removal of
gasoline (including MTBE), fuel oil, chlorinated solvents, and pesticides.
Aeration systems have been installed for extremely high concentrations of
volatile organic compounds in place of, or in addition to the GAC filters.
Pretreatment and post treatment systems have been installed at numerous
locations to neutralize acidic water, remove hardness, iron, manganese, and
hydrogen sulfide which can foul the GAC filters, and treat coliform bacteria and
A typical CTDEP potable water treatment system designed to remove volatile
organic contaminants consists of a 5 micron sediment filter designed to capture
any sediment or debris entering from the main water supply line, two (2) two
cubic foot granular activated carbon filters, and a 5 micron post filter to
ensure sediment free drinking water.
Below are two examples of potable water treatment systems engineered and
installed by DES.
