RE: Hydrant Flow Test
Parsons Wood Subdivision
Dear Board Members:
At the request of Jame§ Boyle, the developer of the Parsons Wood subdivision off
Burts Pit Road, this office conducted a fire flow test on the morning of
Wednesday, June 21, 1989. Representatives from •the City Engineering Department,
Water Department, Fire Department and the developer witnessed the test. A rep-
resentative from the Water Department operated all valves and hydrants.
The test was conducted at 9:00 A.M. At that time, the flow rate from Mountain
Street Reservoir was approximately 4 MGD. Both municipal wells were operating
and the Turkey Hill Road water tank was on-line.
The hydrant at the end of the cul-de-sac was used as the flowing hydrant and the
hydrant located approximately 100 feet in from Burts Pit Road was used as the
residual hydrant. Static pressure readings were 54 psi and 48 psi at the flow-
ing hydrant and residual hydrant, re ; ,ctively. The flow rate was measured as
1110 gpm at 44 psi at the flowing hydrant and the pressure at the residual
hydrant dropped to 45 psi. This measured flow rate converts to an available
flow rate in excess of 2100 gpm at a residual pressure of 20 psi. The available
fire flow exceeds the minimum flow rate required for a development of this type.
If you have any questions, please do not hesitate tq contact this office.
Very truly yours,
ALMER HUNTLEY, JR. & ASSOCIATES, INC.
