This in response to the aforementioned NOV.
During the month of May 2018 The Town of Grover's WWTP experienced several
Illegal dumps into the collection system which adversely affected the WWTP.
I have included pictures of the consequences to the plant, explained later.
We knew these dumps were going on but to this day we are unable to catch the
perpetrator, we have asked for assistance from law enforcement.
On July 4, 2018 we did finally catch an illegal dump entering the plant, pictures included.
A sample was collected and sent to the lab the following day. The results came back 4 to 10
times higher than normal, analysis included.
A plant as small as Grover's is unable to handle these loadings without assistance, so we
have acquired specialty "bugs" for domestic waste once we knew what we were dealing with.
They seem to have helped turn the plant around and we will continue to feed them on an as
needed basis.
