Sewerage Sewerage

Maranoa Regional Council operates sewerage networks in the towns of Amby, Injune, Mitchell, Mungallala, Roma and Surat.  The sewer mains span a length of over 109 km.

Current works


Maranoa Regional Council would like to advise residents of the commencement of sewer manhole inspections.

Council staff will require access to residents’ properties to assess manholes. This will only be a visual inspection and will be undertaken once the manhole lid is removed (this will take approximately 30 minutes). Works have commenced and will continue until 30 June 2019.

Programmed maintenance inspections on sewer manholes is undertaken to determine their condition. These inspections allow Council to plan for a future renewal program and identify whether rehabilitation or replacement will be required.

If manholes are buried or covered, Council will raise manholes to surface level to ensure they are easily accessible at all times. Should this be required, Council staff will liaise with residents on a suitable time to undertake this work.

Council apologises for any inconvenience and thanks residents for their patience.

Maranoa Regional Council’s Roma Sewer Main Upgrade Project will commence next week within the Roma town area.

The project will include an upgrade to 21kms of Roma’s sewer mains and is set to begin on Monday, 7 January 2019 with works anticipated to take five months to complete (weather permitting).

Councillor David Schefe, Portfolio Chair for Utilities said that much of Roma’s sewer mains are reaching the end of their useful life and these upgrades are vital to ensure the effectiveness of the sewer network.

“Relining sewer mains is a cost-effective way to ensure the stability of the sewer network and will increase the longevity of the mains,” Cr Schefe said.

“The project has been designed to minimise disruption to residents, however disruptions, such as road closures and traffic delays may occur while works are underway.”

Please note that while works are taking place, residents are advised that some toilets may overflow. To minimise this occurrence, please be sure to close the toilet lid and place a heavy object on top before the works commence. If you experience toilet overflow issues, a cleaning service will be provided.

Insituform Pacific Pty Ltd will be notifying affected businesses and residents via a letter and/or door knock 48 hours prior to commencing any upgrade works.

Council apologises for any inconvenience and thanks residents and businesses for their patience during this time.

If you experience toilet overflow issues or would like more information, please contact Council’s Sewerage Team on 1300 007 662.  



If your business discharges any liquid waste to a sewer (other than domestic sewerage) then you require a trade waste approval from Council.

A trade waste approval will specify Council’s conditions for discharging trade waste into its sewerage system. The purpose of the approval is to manage the potentially adverse effects of waste, which can cause blockages or corrosion, undermine the sewerage treatment process or be harmful to people.

Trade waste approval is required for a wide range of business activities. Examples of business activities that require trade waste approval are:

  • Food and beverage preparation
  • Manufacturing, including food and beverages, textiles, leather, paper, wood and plastic, tanneries, wool processing, glass, plaster, resin, ceramic or brick manufacture and stone working
  • Farms or clubs using organic and inorganic fertilisers, weedkillers or insecticides
  • Mining
  • Abbatoirs and butchers
  • Metal processing, finishing, fabricating or engineering operations
  • Hospitals, dental clinics, veterinary clinics and educational, testing or research laboratories
  • Vehicle and plant-related businesses (including truck drivers, car parks and transport depots, panel beaters, spray painters, car washes, service stations, wreckers, plant, vehicle and equipment hire and washing)
  • Cleaning services, dry cleaning, carpet cleaning, bottle washing and laundry operations
  • Swimming pool operations
  • Any business activities that involve chemicals such as petrochemicals, pharmaceuticals, inks, paints, photographic chemicals, soaps and detergents.

For more information on trade waste or applying for an application, please contact Council’s Sewerage Team on 1300 007 662.

Sewer Manholes need to be accessible
Sewer manholes are used by Council as access points into our sewer network. Manholes can be located on roads, footpaths, driveways and on private property.

Council own and maintain all manholes across the Maranoa and need to be able to access them at any time for inspections and to access the sewer mains for maintenance or emergency repairs.

If a manhole is located on a private property it is residents’ responsibility to ensure access is available. It should be visible and not covered with soil or any large objects. 

Sewer Relining Program
Council is continually improving its infrastructure. Currently, Council is undertaking a large Sewer Relining Program in Roma (soon to commence in Injune, Mitchell & Surat).

Much of Maranoa’s sewer mains are reaching the end of their useful life and these upgrades are vital to ensure the effectiveness of the sewer network. The program will significantly improve sewerage infrastructure and is a cost effective way to ensure the longevity of the mains.

Works include:

  • Inspecting and repairing maintenance holes
  • Inspection sewer pipes before and after the work with CCTV
  • Cleaning sewer pipes
  • Installing structural liners in sewer pipes
  • Rehabilitating the sewer junctions.

Annual Cockroach Spraying Program
To combat cockroaches, Council treats cockroaches and insect populations in Maranoa sewer networks by fogging sewers annually.

The towns included in the program include, Mungallala, Amby, Injune, Mitchell, Roma and Surat.

As part of the program, Council requires access to sewer manholes and if a manhole is located on private property teams may need to access it to undertake the treatment (this takes approximately 10 minutes).
