Water Efficiency Certificate

When you’re preparing to rent out your premises, as the landlord, there are numerous factors to consider. One important point is to ensure you’re able to pass on the full cost of water consumption to your tenant. The simplest way to be able to do this is to contact Alliance Plumbing and attain a Water Efficiency Certificate, QLD.

Water charging as stated by the RTA (Residential Tenancies Authority)

Property managers/owners are allowed to pass on the full cost of water consumption, provided:

  • the rental property is individually metered (or water is delivered by vehicle), and
  • the rental property is water efficient, and
  • the tenancy agreement states the tenant must pay for water consumption

How to know if you have a Water Efficient Property

Rental properties are considered water efficient if certain water fixtures meet the standards listed below:

  • All internal cold water taps, except those serving a bath, are to deliver a maximum of 9 litres of water per minute.
  • Shower heads are to have a maximum flow rate of 9 litres per minute.
  • Toilets are to be dual flush, with the maximum flush volume of the full flush to be 6.5 litres, the maximum for the half flush being 3.5 litres and a maximum average flush volume of 4 litres (based on the average of 1 full flush and 4 half flushes).

Alliance Plumbing can ensure you meet the minimum water efficient standards required by inspecting your property’s plumbing and updating where necessary.
