Re: Oakwood Water District
Dear Mrs. Paino:
At the Town Board's request, we have explored various
alternates for solving the iron problem in the above
water supply. We have discussed this with CAMO and offer
the following for your consideration:
1. Sampling of the water system should be done for three
(3) months, twice a month, on each well.
2. Testing parameters shall be iron, manganese, sulfides,
hardness, corrosivity and turbidity.
3. The system shall be tested at the well, the storage
tank, and the distribution system. , .
.
4. There are four (4) immediate interim solutions that can
be taken. These are:
A. Clean the storage tank thoroughly.
B. Clean the hydropneumatic tank thoroughly.
C. Completely flush all the distribution lines.
D. Make a survey of individual homes to determine
a pattern, if any, of the problem.
The above work, items 1-4, can be performed by CAMO, if
desired, at a cost not to exceed $2,000.00.
5. There are two (2) more permanent interim measures that
can be taken. These are:
Joseph E. Paggi, Jr., P.E.
Ernst Martin, Jr., P.E., L.S.

'?C',ge Two
A. Installation of two (2) additional hydrants
to aid in flushing operation. The approximate
cost for this work is $4,000.00. If and when
this system is connected to C.W.W.I, these
.. hydrants will be quite beneficial as fire hydrants.
B. Obtain a proposal to internally clean the
distribution lines. This work will have to be
done at some point in time.
6. At the end of the sampling period, decisions can be
made for a more permanent solution:
These 'include:
A. Treatment of the raw water.
(1) filters
(2) sequestering agents
B. Drilling a new well.
C. Do nothing.
7. The ultimate plan calls for a connection to the C.W.~1.I.
This can be done at a time when the source and supply is up-
graded to handle additional flows from outside the improvement
area.
8. Engineering fees for work on this problem will be billed
at an hourly rate, and will vary depending on the amount of time
needed for completion of ,the individual items.
If further information is needed, please contact me.
