164 Goldview Rd. 07/19/2021, Incident Number 202101585
Mr. Boss,
In response to the above -mentioned notice of violation & intent to issue civil penalty for
the SSO at 164 Goldview Rd. MSD would like to provide you with information about the
cause of the SSO and corrective actions taken.
MSD received a call for a sewer leak at 8:01 AM, crews arrived on scene at 8:15 AM.
The crew found the leak coming out of the ground near MSD's force main for
Weaverville One Pump Station. Three MSD combination truck crews responded to
bypass the pump station arriving at 9:30 AM along with two contract septage haulers.
MSD construction crews arrived on scene at 9:40 AM and began excavation at the leak
location. Construction crews found the leak coming from an inch and a quarter sized
private force main that had blown out. The private force main had a check valve that
was nonoperational causing the sewer in MSD's force main to exit through the break in
the private force main. The valve vault for the private force main was located and was
shut off at 11:15 AM containing the SSO.
The private force main check valve that failed was not rated for pressure sewer. MSD
replaced the defective valve with one that is rated for sewer use. MSD replaced fifteen
feet of the private force main including replacing the galvanized fittings with stainless
steel fittings, making the connection more durable and increasing its longevity.
The private force main was added to MSD's mapping system where it had been
previously unmapped. It was added to the six-month inspection cycle concurrent with
MSD's air relief valve inspections.

If you have any additional questions regarding the discharge, please give me a call.
Thanks,
C. Kenneth Stines
