Gisborne District Council is on a mission to ensure the district’s sewer pipes are in the best possible condition. The
DrainWise team is working to identify private property sewer pipes that are in bad condition, and provide guidance to
homeowners on repairing or replacing their damaged pipes.
“This is an essential part of the DrainWise Programme to further reduce overflows to our rivers and onto private
property,” says 4 Waters infrastructure manager Neville West.
“Council is committed to doing everything they can to help homeowners through this process. We need to ensure everyone
complies with the law when it comes to private property drainage, and healthy water and ecosystems. We’re working hard
on the most important part of DrainWise which is making sure homeowners fix leaking sewage systems on their property
including their underground pipes.”
It’s part of a big push by Council to reduce wastewater overflows that can happen during heavy rainfall. In the past
year there have been four overflow events.
“Everyone has a part to play in this,” says Mr West. “Above ground, leaking gully traps are one part of the problem, but
it is what we can’t see underground that also needs attention.”
Half of the city’s wastewater pipes are on private property and because they belong to homeowners, the responsibility
lies with them to ensure they don’t leak. Council inspections of these underground private pipes have shown that about
half are in a poor state of repair. When these pipes leak, they let rainfall into the sewage system which then struggles
to cope, leading to overflows during heavy rains.
“We need the community to help by playing their part. Wastewater overflows cannot be reduced until the privately-owned
underground sewage system isn’t leaking.”
As part of the DrainWise campaign, Council will be assessing private underground pipes on all properties using CCTV and
smoke testing, while making repair work as affordable as possible for the homeowner.
The programme will kick off soon and Mr West anticipates it will run over the next decade, with the aim of having all
required inspections completed within seven years
This will give homeowners enough time to fix faults before the 10-year mark, with the option of fixing them privately,
or taking part in the proposed Council-managed repair process..
“Hopefully this will take the stress out of the job while making it more affordable,” says Mr West.
There is legislation enabling Council to require a homeowner to repair their private pipes, which will be used where
homeowners do not willingly fix their issues. “We’ve had a great response so far with homeowners keen to help once they
are aware of an issue on their property.”
