The Shire of Lake Grace is responsible for the deep sewerage system in the town of Lake Grace only. The deep sewerage in Newdegate falls under Water Corporation's jurisdiction, and Lake King and Varley operate off septic systems. This service is delivered under the Water Services Act 2012 (the Act) and is funded by Specified Area Rates levied against landowners who own land within the Lake Grace town that have the capability to connect to the wastewater system.

Any new dwellings or businesses in the Lake Grace town must be connected to the wastewater scheme (if within close proximity of a main), as required by the Lake Grace Local Planning Scheme section 4.30. As Constructed drawings of the wastewater system can be requested from the Shire free of charge to help assist in locating underground infrastructure for maintenance or new developments.

Extent of Responsibility

Any infrastructure lying within public land--such as verges, parks and sports precincts, laneways and roads, and Shire-owned land, is the responsibility of the Shire to maintain. This may infrequently require roadworks in cases where a mains crossing the road is causing issues.

The wastewater infrastructure includes:

  • Gravity mains made up of PVC or vitrified clay pipes.
  • Pressure poly pipes.
  • Concrete access chambers with manhole covers made of concrete or iron.
  • 4 x wet wells containing submersible pumps and a control panel and covered with chequered plates.
  • Above-ground Imhoff tank.
  • Sludge-drying bed.
  • 2 x clay-lined treatment ponds.
  • 2 x chlorine dosing unit.
  • Steel water tank for holding treated wastewater.

If you notice an issue with the wastewater system in the Lake Grace townsite, please report it to the Shire at (08) 9890 2500 as soon as possible so we can restore service in a timely manner.

For property connections to the wastewater scheme, the Shire's responsibility ends at the junction near your property's boundary, buried below ground. Any issues past this point is the responsibility of the home or business owner.

There are a few private properties where a manhole and access chamber lies within its backyard. Under the Act the Shire has powers of entry without notice to carry out maintenance works as long as it does not cause a disruption to the occupiers of that property. This power of entry only extends to the external areas of a property and not the dwelling or business itself. In cases where excavation works are required to replace underground mains within your backyard, the Shire will seek consent of the occupier to carry out works. If consent is not or cannot be given, the Shire will give a 48 hours' notice of proposed entry before carrying out works.

Reuse Scheme

There is a wastewater reuse scheme in use to help with the irrigation of the Lake Grace football and hockey ovals. It is mostly used during winter months where the treatment ponds are at a high water level. Wastewater is dosed with chlorine during transfer to the steel water tank at the southern edge of the football oval, and dosed again just before it enters the tank to ensure optimal chlorine levels for contact time. Reuse water is used for irrigation throughout the night to allow for enough time for evaporation and safe contact the following morning.

Financial Hardship Policy

Within the Wastewater Services Charter is the adoption of a Financial Hardship Policy. If you find that you are struggling to pay off the wastewater portion of your rates, you may apply to the Shire to be placed under an alternate payment arrangement, or to have your outstanding payments reduced. This process will also halt any debt collection that may occur while assessment and alternate arrangements are in place.

Financial hardship in this case means that the payment of the wastewater portion of your rates would adversely affect your basic living needs.
