A property or group of properties used (or adapted to be used) for living purposes classed as non-residential in nature.

For example: rooming accommodation, boarding houses, student accommodation, aged care, nursing homes, retirement villages, moveable dwelling premises such as caravan and mobile home parks, short-term commercial accommodation e.g. hotels, motels, bed and breakfast and air BNB.

Annual base rate set by Urban Utilities for both water and sewerage services.

Divided by the number of days in a year to calculate the Daily Price for each service.

A group of individually owned, strata titled units that includes common property.

Urban Utilities classifies Community Title Schemes into three groups – CTS Option A, CTS Option B and CTS Option C – for billing purposes.

Simpler Pricing affects each differently. For more on each group, please visit our Simpler Pricing Community Title Scheme change page.

Composite Discharge Factors are calculated for some non-residential Option C Community Title Schemes.

Composite Discharge Factors can be used to better reflect the overall amount of sewage that is discharged back into Urban Utilities' sewer network.

This is particularly important when some of the unit owners in an Option C CTS scheme discharge less sewage back into our network than others.

A Composite Discharge Factor is calculated using each units' Discharge Factor and Water Usage (determined based on their percentage share).

Example calculation: Sewage Discharge Factor 1 x Water Usage 1 + Sewage Discharge Factor 1 x Water Usage 1 = Composite Sewage Discharge Factor.

For example, an Option C Community Title Scheme has 10 units. Nine units have a standard 90 per cent discharge factor, while one unit is a brewery which has a discharge factor of 20 per cent. The brewery is estimated to use 70 per cent of the total water supplied to the scheme. In this scenario the Composite Discharge Factor for the scheme is 41 percent (90% Sewage Discharge Factor x 30% Water Usage + 20% Sewage Discharge Factor x 70% Water usage).

The diameter of the water meter fitting that connects a water meter to Urban Utilities' water network.

A larger connection can draw more water more quickly from our network, resulting in greater flow rate and pressure.

Daily price set by Urban Utilities for water and sewerage services.

A percentage value representing the proportion of water used at a property considered to be discharged back into Urban Utilities' sewers.

Discharge Factor percentages:

  • are determined by Land Use Code,
  • differ across property types and industries, and
  • may be influenced by a business’ activities and how they use water on site.

Discharge Factors range from 0.1 to 0.9 (10 per cent to 90 per cent).

An expression of the concentration of contaminants in typical domestic sewage. Specifically, the contaminants concentrations are 300 mg/L Biochemical Oxygen Demand, 330 mg/L Suspended Solids, 70 mg/L Total Nitrogen, and 12 mg/L Total Phosphorous. For non-residential customers, sewage disposal charges apply to sewage below domestic strength, and trade waste charges apply to sewage equal to or above domestic strength.

A dwelling is a building, or part of a building, forming a self-contained residence, that is used for residential purposes that includes kitchen, bathroom and toilet facilities and is under the exclusive use of the occupier, but which need not be the subject of a rental agreement.

Example include residential flats or apartments, duplexes, free-standing buildings such as houses, bungalows and cabins, and granny flats.

Note: when transitioning to Simpler Pricing on Friday 1 October 2021, all existing single-dwelling residential properties will default to a dwelling count of one.

Dwelling Count is the total number of self-contained dwellings, of a residential nature, within a single land title or lot.

Residential water service and sewerage service charges are billed based on the number of dwellings on a property.

The area of the floor of a premises (i.e. building) such as a store, office, or factory.

Flow Capacity Factor is a numerical value, also referred to as a multiplier, attributed to a water meter, which indicates how efficient it is at allowing water to flow. Each multiplier represents the increased efficiency of larger water meters to draw water from our network compared to standard meters.

Actual Meter Size Multiplier
20mm
25mm
32mm 2.56 
40mm
50mm 6.25 
65mm.. 10.56 
80mm 16 
100mm 25 
150mm 56.25 
200mm 100
Greater than 200mm 126.56
Max  156.25

Combined Flow Capacity Factor is the combined total of all multipliers (Flow Capacity Factors) where there are multiple meters supplying a property.

Land Use Codes indicate the primary use of a property and/or how it has been predominantly adapted to be used by virtue of its structure, fixtures and fittings.

Urban Utilities applies a Land Use Code to an account based on evidence, including:

  • Land use information from Department of Natural Resources, Mines and Energy (DNRME)
  • As-Constructed Plans
  • Google Street View, and
  • On-site inspections.

Each Land Use Code is assigned a Sewage Discharge Factor (SDF) which is used in the calculation of Sewage Disposal charges.

A separate, distinct parcel of land registered under the Land Title Act. Land Title (ownership) can be inclusive of one, or multiple lots.

For the purposes of some strata-titled properties (Community Title Schemes), building format plans define lots by the structural elements of the building. For example: floors, wall and ceilings in a high-rise building are often referred to as a unit.

More than one dwelling or unit can exist on a lot – i.e. granny flats and annexed units.
Non-residential is where the majority of the premises on the property (i.e. units and floorspace area) are used for, or are adapted to be used for, commercial/business purposes.

Also referred to as commercial and/or business.
Predominant use indicates whether a property is used for, or adapted to be used for, either residential or non-residential purposes.

Predominant use is determined to be non-residential when the majority of the units and floor space are non-residential in nature. Otherwise the predominant use is determined to be residential.

A property where the majority of dwellings are lived in or adapted to be lived in.
A charge made by a business.

A tariff is the amount that is charged for a service.

In the case of Urban Utilities, services include water services and sewerage services, water usage, sewage disposal, or trade waste.
A modern pricing approach adopted by utility service providers and governments worldwide. 

Customers pay for the water or sewerage services they use or benefit from. Customers who use or benefit more, pay more than customers who use or benefit less.
