Drainage

Slow drains, odours, overflows and recurring blockages can affect day-to-day operations across commercial and industrial sites. Drainage work considers where water or waste should flow, what may be affecting that path, and the information a plumbing business needs to assess the situation and plan suitable work.

Find the right drainage support

When drainage starts affecting a site

A drainage concern can become more than an inconvenience when it affects a work area, access route, tenancy, plant area or external yard. Slow drainage, unpleasant odours, overflows and recurring blockages are useful signs to record, particularly when they occur repeatedly or coincide with rain, washdown activity or normal business operations.

Commercial and industrial drainage work focuses on moving wastewater, trade waste, stormwater or surface water away from a building, tenancy, site or piece of plant. The immediate task is to understand where the water or waste is intended to go, why it may not be moving as expected, and what information is needed to investigate the issue.

Drainage systems can extend well beyond visible grates

Parts of a drainage system are often below ground, under floors or within service areas. Depending on the site, customers may encounter sewer drains, trade waste lines, stormwater drains, floor wastes, grated drains, pits, sumps, grease arrestors, pump wells, washdown areas and process discharge points.

Visible features can include inspection openings, floor wastes, grates, pits, concrete channels, pipework, trade waste fixtures, sumps and pump stations. Knowing the affected feature and its location can make an enquiry clearer, especially where a large site has several buildings, plant rooms, loading docks, car parks or external areas.

What a drainage enquiry may involve

Drainage may involve inspection and condition assessment, repairs to sewer, waste or stormwater drainage, checks of pits, grates, floor wastes and inspection openings, or alterations and upgrades. A commercial kitchen or trade waste drainage concern may also need a focused review of the affected area and its operations.

Find a Master Plumber lists drainage pathways for CCTV services, cleaning, installation, jetting, repairs and maintenance, sewer and stormwater pipe relining, and tankering. These terms help a customer describe the type of work they are seeking; the right approach depends on the particular site, system and issue.

Commercial and industrial drainage: the context matters

Commercial drainage can involve a building, tenancy or shared operational area. Industrial drainage may need a broader understanding of the liquids and materials present at a site, including trade waste, industrial wastewater, contaminated stormwater, oily waste, chemical-affected waste or controlled waste.

For an industrial site, the activity taking place can be important context. Process water, cleaning chemicals, oil, fuel, solvents, sediment, food waste, metals, chemicals and hydrocarbons may all be relevant details to raise when choosing a plumbing business. Existing permits or approval conditions may also be important to the discussion.

Site setting Useful drainage context to provide
Building, tenancy or facility Affected area, whether the issue concerns sewer, trade waste or stormwater, and when it occurs.
Workshop, washdown area or plant location Site activity, liquids or materials that may enter drainage, and any process impacts.
External yard, car park or landscaped area Whether the concern relates to rain, surface water, pits, grates or external drains.

Prepare useful information before choosing a plumbing business

A clear enquiry helps a plumbing business understand the site and the decision required. Gather what is readily available, rather than trying to diagnose the drainage system yourself.

  1. Record the site address, affected area and best access instructions.
  2. Note whether the issue appears to involve sewer, trade waste, stormwater or surface water.
  3. Describe when the problem occurs and whether it relates to rain, washdown, business activity or another pattern.
  4. Have photos of drains or pits available, along with previous CCTV or jetting reports and site plans where relevant.
  5. Identify access requirements, shutdown restrictions and the person authorised to approve work.

Facility managers, asset managers and maintenance coordinators may also have an asset ID, plant location reference, maintenance history, drawings or previous service records. Industrial operators may need to identify safety permits, isolation requirements, environmental controls, shutdown windows, confined-space risks, hot works requirements and critical production impacts.

Products and supply names customers may encounter

Drainage projects can involve products and supply channels from a range of businesses. Examples customers may encounter include Reece, Galvins, Galvin Engineering, Tradelink, Parkwood Plumbing Centre, Iplex, Vinidex, Everhard, Reln, ACO, Humes, Rocla, Polymaster and Civilmart.

These names are associated with drainage-related brands, products or supply channels. Their presence in site records, product labels or project information can be useful context to share when discussing existing equipment or materials; it does not determine the appropriate drainage solution for a particular site.

Choosing a Master Plumber for drainage work

Drainage decisions often require clear site information, an understanding of operational constraints and a practical conversation about the affected system. Choosing a Master Plumber helps consumers make a more informed choice of plumbing business for their property or project.

Find a Master Plumber connects customers with Master Plumbers and plumbing businesses associated with the Master Plumbers and Gasfitters Association of Western Australia. It is backed by the Association, which has represented Western Australia’s plumbing and gasfitting industry since 1901.

For related site needs, you may also wish to consider storm water systems and drainage, pumps and pumping equipment, leak detection or consultancy.

Drainage questions

What information is useful for a commercial drainage enquiry?

Provide the site address, affected area, access details, the type of drainage involved if known, when the issue occurs, and any photos, plans or earlier CCTV or jetting reports. Shutdown restrictions and approval contacts can also be relevant.

What can cause recurring drainage blockages or overflows?

Possible factors include blockage, pipe damage, poor fall, undersized drainage, stormwater entry, grease, solids, root ingress, collapsed pipework or pump failure. A site-specific assessment is needed to determine what is affecting a particular system.

What is the difference between sewer, trade waste and stormwater drainage?

These describe different drainage pathways that may be present on a commercial or industrial site. Identifying which one is affected, if known, helps frame the enquiry and the relevant site information.

Why does industrial drainage need detailed site information?

Industrial sites may deal with process water, chemicals, oil, fuel, solvents, sediment or other materials that can be relevant to drainage. Production impacts, environmental controls, permits and shutdown windows may also affect planning.

What are CCTV services and jetting used for in drainage work?

CCTV services and jetting are listed drainage service pathways. Existing CCTV or jetting reports can be useful information to provide when discussing a drainage concern.

Can drainage work involve areas outside a building?

Yes. Drainage systems may be located in external yards, car parks, landscaped areas and industrial compounds, as well as under floors, in service corridors, plant rooms and loading docks.

Use Find a Master Plumber to choose a plumbing business for commercial or industrial drainage work. Start with the affected area, site conditions and any operational information that may shape the discussion.
