Building over Council owned drains

If you are rebuilding a house or garage you must check your plans don’t involve building over a Council drain. Christchurch City Council has a Bylaw to protect waterworks and specifies the proximity of building work near drains – including public water, wastewater and stormwater pipes. This is so the Council can check, repair and replace drains quickly and efficiently.
