Sub Metering

The following describes our approach and policy to water sub-metering of existing and new strata schemes and multi-unit properties.

Sub-metering means measurement of water consumption by a lot within multi-unit or strata scheme property, in addition to the master meter at the connection point to our infrastructure.

A master meter is the meter installed at the connection point and measures the total volume of water supplied to a property. Sub-meters are individual water meters that measure water usage downstream of a master meter.

Further details are available in our Sub-metering Policy, section 4 of the Water and Sewerage Network and Charges Policies. The policy has been approved by the Tasmanian Economic Regulator as part of its 2018 Price Determination.

Sub-metering Multi-unit (not strata titled) Properties

There is no legislative requirement to meter sub meter individual units.

All multi-unit properties will have a master meter installed at the connection point. We will use the master meter for our charges. The owner of a multi-unit property has the option of installing sub-meters for each unit. Third parties can install and read these meters on behalf of the owner.

New multi-unit properties

We may, at our discretion, approve each unit being individually and directly connected to our water reticulation main. In this case each individual connection is a master meter for the purposes of this policy.

In existing strata schemes, all lot owners in a strata scheme must agree to sub metering.

In existing strata schemes and multi-unit properties the ability to sub-meter is dependent on plumbing being suitable for sub-metering. For new developments,  property owners are encouraged to consider installing plumbing that will support future sub-metering.

Strata Title Sub Metering

New strata schemes will be metered in one of the following ways:

  • Single master meter only; or
  • Master meter and sub-meters.

New strata title properties will have to install one master meter on the connection entering the property.  Strata property owners have the option of electing to have individual sub meters installed to service each dwelling.

Prior to sub-metering a property the owners need to arrange for a vote of lot owners on whether to install sub-meters and obtain all lot owners’ agreement before TasWater will proceed with any request.

Under the Strata Titles Act it a Body Corporate comes into existence automatically on registration of the strata plan by the Recorder of Titles.  The Body Corporate is made up of all owners of a lot in the strata scheme.  TasWater only acknowledges a Body Corporate, not individual owners.  Where there is no common property, no interposing pipe work and no requirement for a master meter we may, at our discretion, approve each lot being individually connected to our water main.

Billing

The cost of the fixed water charge will be apportioned according to unit entitlements (registered on title with the Lands Title Office).

Should all lot owners’ agree to install sub-meters, , it is important to note that each property owner will be required to pay full individual residential service charge per sub-meter, typically 20mm.

To apply to install sub-meters, please submit a Development Services Application Form, We recommend that you  engage a plumber to confirm that the existing internal plumbing at the property can sustain the installation of sub-meters.  .

Should all owners in a strata scheme agree to sub-metering and the sub-meters have been installed, the body corporate can provide us with a copy of a unanimous resolution authorising billing to be based on the sub-meters. This written confirmation must occur prior to any change of the billing configurations. We will then cease billing from the master meter and commence billing from the sub-meters. 

For all metering arrangements, please refer to our guidelines here.

Further details are available in our Sub-metering Policy, section 4 of the Water and Sewerage Network and Charges Policies. The policy has been approved by the Tasmanian Economic Regulator as part of its 2018 Price Determination.

What will the bill look like?

Common ground usage will appear as a separate line item on the front of an account showing share of the usage (share in kilolitres (kL), Water Usage rate and period of usage).

Meter details, readings and dates will appear on the back as a separate line item under any other meter detail (see below).

A message will also appear on the back of the account highlighting that this is the share of usage for a specific meter.
