Maintenance & Servicing

Liner replacement, internal cleaning and scheduled servicing that keeps a tank watertight and compliant.

What a service covers

Looked at yearly, not annually panicked about

A tank that somebody checks does not usually become an emergency. A tank that nobody checks eventually does, and it picks the moment.

  1. 01

    Internal cleaning

    Sludge and build-up out, floor and walls back to something you can actually inspect.

  2. 02

    Liner replacement

    A worn liner swapped out before it fails, in a shell that is otherwise good for years yet.

  3. 03

    Condition checks

    Eyes on the seams, the seals, the roof steel and the access, and a straight answer on what needs doing and when.

  4. 04

    Scheduled servicing

    Work planned around your shutdown rather than around ours, so the tank is out of service once and not twice.

  5. 05

    Any brand of tank

    We service tanks we did not build. Most of the ones we service, we did not build.

  6. 06

    Nationwide

    Crews working both islands out of Christchurch, so a servicing round does not need a local contractor in every region.

Inside the tank

The part nobody sees

Almost all of this work happens where the owner never looks. That is exactly why it gets left, and why leaving it costs more than doing it.

Cleaning it out

Confined space work, in a harness, moving material that has been settling for years. It is the least glamorous thing we do and the thing most likely to buy a tank another decade.

Relining

A liner is a consumable. The shell around it is not. Replacing one before it goes is a service call, and replacing one after it goes is a very different conversation.

Pending from Charles: what a scheduled service actually includes, whether Impact offers an ongoing maintenance agreement, and at what interval.Pending from Charles: which compliance regimes the servicing is meant to satisfy. The homepage wording says “watertight and compliant” and we should be able to say compliant with what.Pending from Charles: confined space and H&S prequalifications. This page describes confined space work and cannot claim a qualification we have not confirmed.
Where they go

Five sectors, one set of hands

What changes between a fire water tank and an effluent tank is the liner, the fittings and the compliance around it. The steel gets the same treatment either way.

  • Fire waterSprinkler and fire main
  • PotableCouncils and supply
  • WastewaterEffluent and treatment
  • IndustrialProcess water and product
  • AgricultureWater and effluent
