In a release made on the Byron Shire Council media centre site on 6 September 2019, the current Utility Manager (UM) outlines that smoke testing will take place in the Mullumbimby sewer system inclusive of 77 gravity sewer lines and associated private junctions.
The UM also said identifying and resolving leaks, defects, and incorrectly installed storm water connections into the council’s sewer mains will help reduce the incidence of flooding or overflow on private property. How?
The UM also states that the Council’s storm water and sewer mains were recently pressure cleaned and inspected for leaks and defects via CCTV inspection. Has the result of this inspection been submitted to the Waste Water Advisory Committee for discussion, particularly the condition of the deep gravity mains?
I did submit a question previously as to the rising sewer main being replaced at the Stuart Street pump station in Mullumbimby, the reason given was because it was past its use-by date. I asked what does this say about the structural integrity of the gravity sewer mains laid at the same time?
The answer I received was that there is no relevance between the two as the rising main is built of a superior material and it is built to withstand internal pressure.
Well again, I have to ask, as the material used to construct the gravity is of a lesser strength material than the rising main, what does this say as to the gravity mains condition? No name was forwarded with the reply to my question.
