Discuss your sewer conversion with the right plumbing business
When a sewer conversion becomes the right conversation
Changing the wastewater arrangement at a home is rarely just a matter of connecting one pipe to another. A sewer conversion may move a property from septic or an older wastewater disposal arrangement to a sewer connection, or change the route by which wastewater leaves the property.
Much of the work can be underground. Existing drains, inspection openings, connection points and old tanks may all need consideration before a clear scope can be established. For a homeowner, landlord, tenant, strata owner or property manager, the useful starting point is to explain what is changing at the property and share any information already held about the existing system.
What can affect the scope of a sewer conversion
Each property has its own layout and existing infrastructure. Before connecting to an approved sewer point, a plumbing business may need to confirm levels, pipe grades, connection depth, access and the condition of existing drains.
Unknown pipe routes, buried tanks, damaged older drains and tree roots can affect the work. The amount of restoration needed after excavation, such as paving or landscaping, may also be part of the broader conversation. These factors are why a conversion is often best considered as a planned, property-specific item rather than assumed to be a simple change.
Septic to sewer conversion: understanding the change
A septic to sewer conversion changes the wastewater disposal arrangement at a property. It can involve existing drains and a new connection pathway, as well as decommissioning or bypassing an old tank. The practical requirements depend on the condition and route of the existing drainage, the location of the connection point and site access.
It is helpful to distinguish this from work on a septic tank itself. Septic tank installation and repair concern the tank arrangement, while a sewer conversion focuses on changing the disposal pathway. A plumbing business can assess the information available and determine whether the matter is suited to a quick service call, a planned repair or a larger scoped item.
Signs and property information worth raising early
Slow or blocked drainage, wastewater backing up, or uncertainty about where existing pipes and tanks are located can be important details to raise. These observations do not identify the cause on their own, but they give a plumbing business useful context about the property and its drainage arrangement.
Which fixtures are affected and whether the issue is inside or outside
Whether sewage or stormwater is backing up
The location of any known inspection openings, pits or tanks
When the issue started, how often it occurs and what seems to make it worse
Whether there are known access constraints around the affected area
Prepare for a clearer discussion with a plumbing business
Good information can make the first discussion more productive. It also helps separate known facts from details that need to be checked on site.
Identify the property. Have the address, a contact person and clear access instructions ready.
Describe the situation plainly. Note what has changed, which fixtures are affected and whether the area is occupied.
Share useful visuals. Photos or short videos of the issue, surrounding area and labels on existing equipment can provide useful context.
Gather records. Previous quotes, reports, maintenance history and product documentation may help explain what is already known.
Point out key locations. Mention known inspection openings, pits, tanks and suspected pipe routes where possible.
Products and supply names you may encounter
Conversations about underground drainage, pipework, pits and related materials can involve a range of product systems and supply channels. Examples customers may encounter include Reece, Galvins, Tradelink, Iplex, Vinidex, Rehau, Everhard, Reln, ACO, Humes and Rocla.
These names are examples associated with the wider product and supply landscape for this service. Their appearance in project information or product discussions does not mean that every plumbing business uses, installs, services or recommends a particular brand or product.
Choosing a Master Plumber for sewer work
A sewer conversion can involve existing underground infrastructure and a change to a property’s wastewater pathway, so it is worth choosing a plumbing business with a clear understanding of the work you need discussed. Explain the property arrangement, share any relevant records and ask how the existing drains, access and connection details will be considered.
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. Choosing a Master Plumber helps consumers make a more informed choice of plumbing business for their property or project.
Other sewer services that may be relevant
Not every wastewater issue calls for a conversion. If the existing arrangement needs attention rather than a change of disposal pathway, a more specific sewer service may be the better starting point.
Sewer installations: for discussions about new sewer infrastructure.
Septic tank installations or repairs: where the tank arrangement itself is the focus.
Aerobic treatment unit installations, repairs and servicing: where an ATU is involved.
Greywater system installations or repairs: where a greywater system is the subject.
Sewer and storm water pipe relining: where pipe relining is being considered.
Frequently asked questions
What is a sewer conversion?
A sewer conversion usually changes a property from septic or an older wastewater disposal arrangement to a sewer connection, or alters the way wastewater leaves the property.
What information should I provide about my property?
Provide the address, contact and access details, describe the affected fixtures or area, and share photos, videos, previous reports or maintenance records where available. Known inspection opening, pit and tank locations can also help.
Why do existing drains need to be considered?
Existing drains form part of the property’s wastewater arrangement. Their condition, route and connection details can affect how a sewer conversion is scoped.
Can an old tank affect a sewer conversion?
It can be relevant. A conversion may involve decommissioning or bypassing old tanks, and buried tanks are among the site details that may need to be identified.
Are sewer conversions always straightforward?
No. Unknown pipe routes, insufficient fall, damaged old drains, tree roots, access and restoration after excavation can all affect the scope of work.
