Drainage Estimating Services in Australia

Drainage jobs are won on pipe lengths, pit counts and trench depths. Nextron Estimating Pty Ltd provides drainage estimating services for drainers, plumbers, civil contractors and builders across Australia. We measure the stormwater and sewer layouts from your plans and price the work, so you can quote with confidence.

What a drainage estimate includes

  • Stormwater and sewer pipe lengths by size and material
  • Pits, junctions, inspection openings and grates
  • Trench excavation, bedding and backfill
  • Connections to existing drains and to the street
  • Rainwater tanks and on-site detention, where shown
  • Labour, plant and a clear cost breakdown

Pipe schedules by depth

We group pipe runs by size and trench depth, because depth changes the cost of digging, shoring and backfill.
