WQCS00144_NOI_NOV2022DV0042_Response_20230220

The NOV/NOI was received by Madison Public Works Dept on 2-17-23. The Town
Manager called Public Works Director regarding the letter on Friday 2-17-23. He said he
did not know when he received it but found it on his desk Friday. Josh Shuler(PW
Director) immediately called the office of Ron Boone and Gary Hudson. There was no
answer so a voicemail was left with each. Monday 2-20-23, both Ron Boone and Gary
Hudson separately returned the calls. We discussed this issue and how to follow thru to
correct this problem.
Action taken concerning the SSO at 810 Cure Drive
We received a call after hours on 12-12-22 at approximately 4:30pm about a sewer/gas
odor at 810 Cure drive (Dillard Academy). Oncall personnel met with the Principal of
the school on 12-12-22 to determine the source of the odor. Upon inspecting nearby
sewer manholes and the surrounding area, oncall personnel could not determine any
issues at that time. The next morning (12-13-22) at 7:05am, we went back to the school
to further investigate the complaint. Upon looking over the area again, we noticed water
running in a storm drain in the school parking lot. The strongest sewer odor seemed to be
coming from that area. At that time, it hadn't rained in a few days so we then checked
the next upstream drain and there was significantly less flow in it. We immediately used
our cctv unit to inspect the storm pipe. We discovered a hole in the storm pipe that had
water running in it. We determined this location was very close to where the storm pipe
and sewer main cross. At that time we began to jet the sewer main to clear any blockage
that could have been part of the problem. We jetted the entire length from section D12
manhole A72 to section E13 manhole A62. After jetting, we used cctv unit to inspect
sewer main. We discovered an offset section of the clay sewer main which appeared to
be where the sewer main and storm pipe cross. From the camera it looked like someone
had cut a 2 foot section out of the sewer main and put it back. Our thoughts are that they
(a previous contractor for the school system) removed this short piece to install the storm
pipe below. We immediately called in an emergency locate and got a crew and material
for repair together. The final locate was not complete until the following morning (12-
14-22) around 9:00am. We dug down on sewer main and found that the sewer main had
been cut where the storm pipe was installed as we suspected. The cut/repair had
apparently not been sealed or compacted properly which led to the short piece dropping
to create this issue. It created about a 2 inch offset. We made a repair by replacing 10
feet of the sewer main with 10 inch pvc. In response to the spill, we inspected the ditch
that the storm drain dumps. We raked up grey matter from spill, placed straw bales
across ditch where drain deposits. We put down lime and used a near by hydrant to flush
out drain pipe and ditch per Gary Hudson's advice. We took before and after pictures of
the spill cleanup. Upon further inspection of the spill after initially reporting it, we
estimate that 8,000 gallons were spilled with 8,000 reaching surface water.
We feel there was nothing that the Town of Madison could have done to prevent this SSO
since it was caused by another contractor's faulty work. We do feel that we responded as
speedily as possible to correct the problem once it was found.
