Mayor Simon Richardson’s description of budgetary spending for 2019/20 by Byron Shire Council (Echo 29 May) includes yet another $500,000 dollars allocated for inflow/infiltration investigation in Mullumbimby. This is in addition to what has already been spent since 2002 with no resolution to date of the problem.
Can we clarify an important fact here! Sewer pipes and stormwater pipes are two different systems. Sewer pipes deliver raw sewage to the sewage treatment plant for treatment. Surface water/ stormwater is collected by the stormwater system and goes to the river.
We hear the same old argument used; it’s faulty or illegal connections causing this infiltration problem. Over four hundred houses were tested and repaired after smoke testing of the gravity mains in 2008.
So why is Water and Recycling (W&R) and the director of Infrastructure still blaming the Mullumbimby homeowners for this problem?
They both seem intent on avoiding the fact that they could have a problem with the condition of the earthenware deep gravity mains that were laid in 1963.
Why are our rates being spent on another five-year investigation while requests to investigate and report on the condition of the gravity mains goes unheeded?
The apparent refusal to show any sort of interest in cameraing the gravity mains and removing them as a source of the infiltration is absurd.
The question now is if those deep gravity mains are in a state of disrepair how much raw sewage has been leaching into the Mullumbimby groundwater system?
