When you need site services

  • An extension, new bathroom or laundry that needs new drainage
  • A granny flat or secondary dwelling
  • A new house on a vacant block
  • A subdivision or multi-unit development
  • Upgrading old stormwater as part of a renovation

What’s involved

  • Locating existing sewer, water and stormwater services
  • Excavation and laying new drainage to the correct fall
  • New sewer junctions and connections
  • Water services and meter connections
  • Stormwater to a lawful point of discharge
  • Inspections and the paperwork the water authority needs

Planning ahead

Sewer and stormwater levels decide where a new building can drain to, so it pays to check them before plans are finalised. A camera inspection of existing lines and a look at the authority’s records early on can save a costly change later.

Working with builders

We work from the plans and the authority’s conditions, coordinate with the builder’s program, and leave the site ready for the next trade.

Common questions

Does a granny flat need its own sewer connection?

It needs to connect to the sewer, usually through the existing house drain or a new junction. How it connects depends on the levels and the location of the sewer on your block, which we check before quoting.

What is a sewer that runs through my yard?

Many blocks have a council or water authority sewer main running through them. Building near or over it has rules, and work on the main itself is done with the authority's approval.

Do you work from the builder's plans?

Yes. Site services are quoted from the hydraulic plans and the conditions from the water authority, so the price matches what has been approved.
