Everything You Need To Know About A Water Efficiency Test NSW

What is a water efficiency test, what’s a water efficiency certificate, and why is it important? In NSW, it’s important to carry out testing to ensure that if you have a rental property, let to a tenant, it makes the best use of water. This is because NSW has a water infrastructure in line with rainfall and weather conditions, which involves not wasting the most precious resource of water in our plumbing. 

The test itself is easy enough to perform: it checks whether more than 9 litres of water flows into a basin during a one-minute timed period. However informative this test may be, it will not tell you if you have leaks or blockages, which can cause plumbing damage to your property and cost you and your tenant more money in water usage.

Water Efficiency Certificate NSW & Investment Properties

Unlike electricity and gas, water services remain connected under the landlord’s account. As a landlord, you are responsible for covering all water and sewerage service fees, excluding water consumption charges. To comply with regulations, landlords in New South Wales must obtain a Water Efficiency Certificate NSW or Water Compliance Certificate NSW, verifying that the property meets prescribed standards. 

Landlords must supply tenants with a copy of the relevant section of the water bill or similar documentation showing usage costs. Any and all Payment requests have to be issued within three calendar months of the billing date. This allows the tenants a further 21 days to make payment. Importantly, water usage charges must be billed separately from the rent. Additionally, conducting a water efficiency test helps confirm compliance and may influence the overall water efficiency certificate cost, reducing potential disputes. 

Water Usage & Water Efficiency Standard in NSW  

It’s a common misconception that tenants are automatically responsible for the cost of water consumption costs they use when landlords can charge tenants for water based on usage. In New South Wales, landlords can only request tenants to pay for water usage if the following conditions are met: 

– The property is separately billed on a meter.  

– The charges align with those stated on the water supplier’s bill.  

– The property complies with required water efficiency standards.

This should be confirmed through a Water Efficiency Certificate NSW or Water Compliance Certificate NSW, which can help in reducing overall water charges. 

These conditions ensure tenants are charged only for actual water usage, provided the property meets the proper efficiency requirements. For additional information, landlords can refer to the NSW Fair Trading guidelines on water usage in rental properties. 

If tenants tamper with or remove water efficiency measures, they may be legally responsible for replacing them and covering any extra costs. This highlights the importance of landlords ensuring compliance with water efficiency standards in NSW. 

Landlords must cover all water supply service fees (excluding usage charges) and all sewerage service fees (excluding pump-out septic service charges). For social housing, the Department of Communities and Justice sets these charges according to its official guidelines. Understanding all of the relevant guidelines and regulations assists landlords in meeting all of the correct legal obligations while managing costs effectively. 

By ensuring compliance with these standards, landlords can meet their obligations while providing tenants with water-efficient and cost-effective properties, including those with flush and 4-half flushes. Andrew Vanny Plumbing offers expert guidance and services to help landlords maintain compliance and avoid disputes. NSW Water Efficiency is crucial for maintaining low water usage and costs in rental premises.
