Drainage installation is a significant decision when building, fitting out, altering or upgrading a commercial or industrial property. Water, wastewater, stormwater and process discharge may move through different parts of a site, and the drainage arrangement needs to suit the activity taking place around it.
A commercial drainage installation may involve new sewer, waste or stormwater drainage, while an industrial drainage installation can also need to account for washdown, process areas, oily water, sediment, chemicals or other site-specific discharge. The practical aim is a system that is suitable for the waste stream, accessible for maintenance and considered alongside the building layout, equipment and operations.
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 a useful place to choose a plumbing business for a project and discuss the particular drainage work required.
What drainage installation can involve
Commercial and industrial drainage systems can be below ground, under floors, in service corridors, car parks, plant rooms, kitchens, workshops, loading areas and external yards. What is needed will depend on the site, the intended discharge and the planned use of each area.
Sewer, waste and stormwater drainage pipework
Trade waste drainage and pre-treatment connections
Grease arrestor and separator connections
Oily water separator and wash bay drainage
Sumps, pump wells and pump station connections
Floor wastes, grated drains, trench drains and pits
Process drainage and containment arrangements
Pipe systems using materials such as HDPE, PVC, stainless steel, copper or specialist products
Testing, commissioning and handover documentation
For a commercial stormwater drainage installation, site levels, external areas and the path water is intended to take are important considerations. For amenities and internal areas, floor levels, fixtures, equipment locations and the required maintenance access can shape the arrangement.
Different sites call for different drainage thinking
A restaurant or commercial kitchen may have different drainage and trade waste considerations from a warehouse, hospital, school or shopping centre. Workshops, factories, laundries, laboratories, wash bays, depots and processing facilities can each introduce their own operational details.
For example, a workshop or wash bay may need the drainage discussion to account for oily water, sediment and washdown activity. A processing area may require attention to the liquids used, cleaning methods, discharge points and potential chemical exposure. In high-traffic areas, the layout and traffic loads can matter when planning pits, grates and channels.
Information that helps a plumbing business assess the work
Clear project information can make the first conversation more productive and help identify matters that need coordination with the builder, consultant, site manager or other parties. Where available, prepare:
Plans and layout details: drawings, hydraulic plans, floor levels, fixture schedules and equipment layouts.
Discharge information: the expected discharge type, process details, cleaning methods and any likely oil, sediment or chemical exposure.
Site conditions: access requirements, traffic loads, plant locations and areas that may be difficult to reach.
Project coordination: builder or consultant contacts, shutdown windows and the person authorised to approve variations.
Existing records: relevant drainage plans, reports or information about prior work where these are available.
Industrial sites may also need to raise process impacts, safety permits, isolation requirements, environmental controls, confined-space risks, hot works requirements and critical production impacts as part of project planning.
New installation, alteration or replacement
Drainage work is not limited to a completely new building. It may be considered during a commercial fitout, a change in the use of an area, equipment replacement, a site upgrade or an alteration to existing drainage. The relevant question is whether the existing arrangement suits the planned activity, discharge and access needs.
Where an existing system is involved, useful context can include known drainage locations, previous CCTV or jetting reports, the areas affected by recurring slow drainage, odours or overflows, and whether conditions change with rainfall or business activity. Those observations do not identify the cause by themselves, but they can help frame a more informed discussion.
Products and equipment customers may encounter
Drainage projects can involve products, equipment and supply channels from a range of businesses. Examples customers may encounter include Reece, Galvins, Tradelink, Iplex, Vinidex, Everhard, ACO and Smartstream.
These names can arise in conversations about drainage materials, pits, channels, grates, pipework or supply arrangements. Their appearance does not determine what is suitable for a particular project; the relevant choice depends on the drainage purpose, site conditions and the system being planned.
Choosing a Master Plumber for drainage work
Commercial and industrial drainage installation often intersects with site operations, access restrictions and coordination between multiple parties. When comparing plumbing businesses, explain the project setting, the intended use of the area, the discharge involved and any operational constraints early. This makes it easier to have a focused conversation about the work.
Find a Master Plumber is backed by the Master Plumbers and Gasfitters Association of Western Australia. Choosing a Master Plumber helps consumers make a more informed choice of plumbing business for their property or project.
Where the work relates to an existing drainage issue rather than a new installation, a different drainage service may be more relevant. Inspection, cleaning, jetting, repairs and maintenance, pipe relining and tankering are separate drainage pathways that may be considered according to the site and the work required.
Questions about drainage installation
What is commercial drainage installation?
Commercial drainage installation relates to drainage systems for commercial buildings and sites. It may include sewer, waste, stormwater, trade waste, pits, floor wastes, grates, sumps, pump connections and other drainage elements, depending on the project.
What information should I provide for an industrial drainage installation?
Useful information may include drawings, expected discharge type, equipment layout, floor levels, cleaning methods, access requirements, shutdown windows and site contacts. For industrial operations, it can also help to identify process impacts, permits, isolation requirements and environmental controls.
Can drainage installation be part of a commercial fitout?
Yes. Drainage may be part of a commercial fitout where the planned tenancy, equipment or activity requires sewer, waste, stormwater, trade waste or other drainage arrangements.
What is the difference between stormwater and trade waste drainage?
Stormwater relates to water from rainfall and surface runoff. Trade waste can arise from business or industrial activity. The expected discharge is an important part of planning the appropriate drainage arrangement.
When might pits, grates or trench drains be considered?
Pits, grates, floor wastes and trench drains may be part of drainage arrangements in areas such as car parks, workshops, wash bays, commercial kitchens, loading areas and external yards. Their relevance depends on the site layout and intended use.
Why discuss maintenance access during installation planning?
Commercial and industrial drainage systems need to be accessible and maintainable. Considering access while planning can help ensure that practical site requirements are part of the conversation from the outset.
