with cut: Sewer Line Installation Is 90 Percent Complete

B Y A NDREW G OROSKO

Almost 90 percent of the sewer lines in the town's sewer system have been

installed, according to John Whitten, chief inspector on the project.

Mr Whitten, senior project representative for Fuss and O'Neill, Inc, the

town's consulting engineers, said Tuesday the last major length of sewer line

remaining to be installed lies alongside Mt Pleasant Road between its

intersection with Diamond Drive and its intersection with Currituck Road.

Most of that sewer trunk line will be installed on the west side of Mt

Pleasant Road, with the remainder placed along the east side of that street.

The sewer installation work by Baltazar Contractors is part of the town's

ongoing $34.3-million sewering project which began in November 1994 on Taunton

Lake Drive.

The town's sewage treatment plant now under construction on an eight-acre site

at the end of Commerce Road is about three-quarters complete, Mr Whitten said.

In December 1995, the Water Pollution Control Authority (WPCA) chose C.H.

Nickerson and Company, Inc, of Torrington to build the treatment plant for

almost $8.8 million.

Major work at the treatment plant that remains to be done includes installing

equipment such as pumps and electrical components, Mr Whitten said. Also, the

buildings at the site will be completed. A road has been extended from

Commerce Road over Tom Brook to the treatment plant site. The road has yet to

be paved.

Workers are aiming for a September 7 treatment plant completion date, Mr

Whitten said.

After the new plant is running, the existing treatment plant which serves

Fairfield Hills will be turned off and its wastewater flow diverted to the new

plant. Sewage flows from Fairfield Hills will be used to test the new plant's

capabilities before it is put into town service.

Fairfield Hills, a former state mental hospital, is now used by Addiction

Prevention Therapy for drug rehabilitation and by the town for office space

and a library.

Also, wastewater will be routed to the new treatment plant from Nunnawauk

Meadows and Garner Correctional Institution.

About one-third of the wastewater handling capacity of the

million-gallon-per-day treatment plant is designated for town use, with the

remainder reserved for the state.

When wastewater arrives at the treatment plant from various directions, it

will be combined in a headworks building, channeled into a series of oxidation

ditches, and then exposed to ultraviolet light for cleansing. The wastewater

collected by 21 miles of town sewer lines will then enter clarification tanks,

after which it will enter a filtration building before being discharged into a

drainage channel leading to the Pootatuck River.

A town sewer transmission line, planned to link Newtown High School to the

sewer system via Sandy Hook Center, is scheduled for completion this year, Mr

Whitten said.

The high school sewer line extension wasn't planned as part of the town's

sewer system. But a groundwater pollution problem discovered near the high

school last year resulted in the school being included in the sewer district.

In the coming months, four sewage pumping stations will be installed to make

the sewer system function. The pump stations will be installed on Hanover Road

near Blakeslee Drive; near the end of Taunton Lake Drive; on Glen Road near

Church Hill Road; and on Baldwin Road.

Sheds, which will house electrical generators at the pumping stations, will be

somewhat larger than initially planned to comply with applicable electrical

safety codes, Mr Whitten said.

After the sewer system is complete, the town will set a time period during

which residential and non-residential customers will be required to connect

their wastewater drains to the system. The out-of-pocket costs that sewer

users will bear to physically connect to the system will vary depending on the

complexity of their particular sewer hookup.

Building a municipal sewer system was discussed for decades before voters

approved bonding for the project in 1992. The system is being built to rectify

longstanding groundwater pollution caused by failing septic systems in Sandy

Hook Center, the Borough, and Taunton Pond North.
