static pressures at the plant inlet vary from 20 to
40 psi. 'Clean filter' he~dloss is 10 psi.

Raw water delivered to the ,water plant meets all EPA
and state standards for ch~mical and organic
constituents. The main contaminants removed in the
water plant are turbidity, 'coliforms, and color.

The present maximum daily demand is 280 gpm, with the
existing population. The rated plant capacity is 400
gpm. Although the filters ,have adequate capacity for
turbidity and coliform rem~vals, high concentrations
of color in the raw water ~till present a problem.
It may be possible to solv~ this problem through
careful selection of alum ~nd polymers, and by adding
the chemicals near the reservoir to increase
detention time.

2. Distribution Svstem Evaluation.

The existing water distrib~tion system serves both
the Town of Norwood and th~ rural areas to the west
and east. The water syste~ consists of a main line
pipe, which extends south ~rom the water plant to
Highway 145, then west alo~g the highway to the Town
of Norwood; from there it oontinues west to the
communities of Coventry and Redvale. Total length of
the main line pipe is over '17 miles. Pipeline
laterals extend north and ~outh from the main line to
serve rural users and the ~own of Norwood. From the
water plant to the Town of ,Norwood, the pipe is 10
inch Class 200 PVC; from Norwood to Redvale it is 6
inch Class 160 PVC; and we~t of Redvale it is 3 inch
,
and 4 inch Class 160 PVC. :All lateral pipelines are
2 inch, 3 inch and 4 inch diameter. There is a total
of 236,400 lineal feet of pipe in the system
including the Town of Norwqod.

Except for a grid network ~ithin the Town of Norwood,
there is almost no looping lin the system.

There is almost 1100 feet qf elevation difference
between the main storage tank and the termination of
the line 2 1/2 miles west of Redvale. Because of
this, the main line has four pressure reducing valves
(PRV's) located at strategic locations. static
pressures range from a high of 140 psi to 30 psi.

There are two storage tanks; which serve the system.
The main tank located at t~e water treatment plant
has a capacity of 250,000 gallons; a 100,000 gallon
