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 109kms.​​​

Trade Waste

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.

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). ​​
