The long-awaited removal of ACT rules requiring the installation of greywater pipe systems in new home builds and existing homes under significant renovation, has been welcomed by the Master Plumbers Association ACT (MPA ACT).
“The relaxation of these requirements comes into effect today and the MPA ACT thanks the Government for making these changes following years of campaigning from Canberra’s plumbing industry. These changes to the ACT’s water and sewerage regulations means less red tape and lower costs for new homes and renovations,” MPA ACT Chief Executive Officer, Joe Prevedello said today.
“Greywater pipe systems have been mandatory since the mid-2000s adding thousands of extra dollars in cost to new home builds and renovations in the ACT. Most of these systems are never used, with only a handful of homeowners paying to activate them in the last 20 years.
“From now on, development applications and building approvals won’t require these greywater systems. They will be voluntary – which directly reduces the cost of building a new home.
“This is an excellent example of red tape governments should seek to remove, as the rules failed to deliver what was intended, while reducing choice for new home builders, owners and residents. Canberra’s plumbing industry is commended for identifying this issue and advocating for its removal for the community’s benefit.
“We thank Treasurer and Planning Minister Chris Steel for taking this decision that the MPA ACT has long advocated for and seeing through the removal of the rules. It will go some way to reducing the cost of new homes during a housing crisis,” Joe Prevedello concluded.
