Connections to Water Corporation sewer
mains are provided via a connection point,
which must be installed or supervised by a
Water Corporation representative.
It is an
offence to connect private plumbing work
to this connection point without approval.
There is a risk to lives and health if the correct
precautions are not taken
In addition to obtaining Water Corporation
approval to connect to sewer mains, licenced
plumbers are required to adhere to PLB
requirements, please visit the Building
Commission website for further information.
It is essential that the licensed plumbing
contractor/builder confirms there is adequate
fall to the sewer main prior to starting building
construction. The conditions a builder must
comply with are included with the approval.
Other important requirements are:
• Confirm location of the sewer connection
point;
• Provide for overflow relief;
• Corporation access chambers must be kept
clear for ease of access;
• Maintain minimum cover levels on
Corporation sewer mains;
• Exercise caution when changing site levels;
• Verify the location of existing pipe work
prior to construction or connection;
• Obtain separate approval where industrial
or commercial waste will be discharged; (see
Section 8); and
• Provide backflow prevention devices
for specified industrial and commercial
developments
