Council water, Council sewer
Council delivers drinking water, recycled water and sewerage to about 36,000 customers across the region, through 8 separate water supply schemes. The Gympie scheme is the largest, serving 66 percent of connected customers, with water from the Mary River backed by releases from Borumba Dam.
The Council pages we read don't say where its sewer ends and your drain begins, or who pays for a blockage near the boundary. Ask Council before you pay for one, and see who owns the sewer pipe for how other authorities draw that line.
Gympie facts that change a plumbing job
Reflux valves in flood hazard areas
Council requires a reflux valve on new homes, and on additions to existing homes, in a flood hazard area. It stops wastewater backing up from the sewer or an on-site system in a flood, must be fitted by a licensed person, and has to stay accessible for maintenance.
Southside is moving off septic
Under a Sewer Connection policy dating from 2011, Council is connecting Southside septic properties to sewer because of the environmental impact of septic tanks in an urban area. Owners can have a licensed plumber of their choice do the connection, or connect through Council.
Treatment plants need an endorsed drainer
Away from the sewer, Council says keeping an on-site sewage facility in good condition is the owner's responsibility, including regular servicing by an endorsed licensed drainer under the plant's state approval.
Frost most winters
The Bureau's Gympie station averages 9.8 days a year at 2°C or below and 2.7 at 0°C or below, from 61 years of records. Exposed pipes are worth lagging before June.
Houses, hot water and water quality
At the 2021 Census, 91.2% of occupied homes in the Gympie council area were separate houses, and 42.1% were owned outright, well above Queensland's 29.1%. Most jobs are one household's own pipes, tank and drains.
Council's 2024/25 report puts total hardness in the Gympie scheme at 50 to 91 mg/L in the network. Any new or replacement hot water system in Queensland needs a temperature control device. Our Gympie hot water page covers the rest.
Checking a Gympie plumber
Plumbing licences come from the QBCC, which runs a licensee register and an occupational plumber and drainer register, both searched through myQBCC. Look up the company and the person doing the work, and for septic and treatment plant work, ask about the drainer endorsement.
For other jobs, start with blocked drains, septic systems, sewer repairs or an emergency plumber. State rules are on our Queensland page.
What we would do
If you're building or extending in a flood hazard area, put the reflux valve in the plans from day one and make sure it can be reached for maintenance. In Southside, get a price from a licensed plumber of your choice and compare it with Council's connection option before you decide. If you rely on a treatment plant, book the servicing with an endorsed drainer rather than waiting for a smell or an alarm.
