1998 Annual Report of the Water District
JERICHO -UNDERHILL WATER DISTRICT
OCTOBER 1, 1997 - SEPTEMBER 30, 1998
The Jericho-Underhill Water System is a municipally-owned public water system that supplies water of excellent quality and adequate quantity to about 800 people in the Underhill Flats area. Recent tests for pesticides, volatile organic compounds (including trihalomethanes), gross alpha, cyanide, and, of course, monthly bacteria are all well below the standards established by the EPA and State Drinking Water Programs.
The Board had planned to replace some under-sized water pipe on Poker Hill Road to improve water pressure. However, the project was postponed until next year due to flooding by Roaring Brook. A leak in the 8 inch A.C. line near 21 Brookside Drive was repaired and a new resilient type of gate valve was installed to replace the old disc valve.
The Board purchased and installed a de-humidifier at the Control Building. This resulted in elimination of the condensate on the internal water pipes, thus minimizing corrosion. Also, a chemical hand pump was purchased for transferring chlorine. A red alarm light remains at the Control Building at 58 River Road, but the warning light on the fire station was removed. A new pager system has been installed whereby two board members and the operator have receivers to alert them for high and low water levels and low heat in the control building. A sign was installed on the access road gate identifying the area as a water supply recharge zone at 58 River Road.
A new three inch blow-off device was installed at the end of the main west on Route 15 near David Villeneuve's property. There were two new water service connections made this year.
The system was flushed several times which improved aesthetic quality of the water being delivered. An improved chemical pump was installed to inject polyphosphate at a more rapid injection rate in order to improve mixing to obtain better sequestering of the manganese.
A large area around hydrant number 34 at the end of Harvest Run in Underhill was finish graded and seeded. This included removal of some small trees to keep the area accessible.
Ditch clearing work was done on the Pump House No. 1 access road ditch and reconstruction at its confluence with the creek was also done. Considerable soil, washed down from Roaring Brook, has tended to raise the creek bed where this ditch drains into it. A protective earth berm was breached to enhance water flow through the yard area of Pump House No. 1. The storage shed roof was patched at Pump House No. 1.
Sealed atmospheric tanks were added to four high elevation homes served by the District’s system. This was done to eliminate the chance of backflow and improve the water pressure to previously served homes with low pressure. Now adequate pressure can be sustained at these homes with no contamination risk to the system. The four tanks were installed at 45 Meadow Lane, 46 Sugar Hill Road, 70 Maple Ridge Road and 53 Maple Ridge Road at no capital costs to the owners
The Board is now set up for the provision of remote emergency electric power by Southworth Miller Corporation out of the Concord, New Hampshire area. Also, to enhance readiness, the Board has provided the fire department with valve wrenches in case a Water District official is not reachable to shut off water.
Janet Peryea replaced Owen Boardman as meter reader last spring as the Boardman’s moved out of town. A new generation meter reader and meter are being installed as meters become worn out or defective. The new pro‑ readers are more dependable.
Next year, the Board plans to hire a person to check and record curb stop locations and enter the data on disc so we have quicker recall of curb stop locations and other pertinent information, Poker Hill water main replacement is also planned.
Daily water usage varied from 47,300 gallons per day to 64,500 gallons per day. Average daily use was 53,000 gallons per day.
The water district is paying off two bonds, one for the main system improvement of 1971 and the other for the new water source that was developed in 1991. Annual income is $82,000 of which 25c for each thousand gallons delivered dedicated to painting of the storage tank. This will provide approximately $4,500. per year for this important purpose.
