The assessment of safe drinking water quality is determined by the Australian Drinking Water Guidelines (ADWG). We provide an easy to read and understand comparison of your test results to the ADWG. 

Tank water can be tested to check physical and chemical properties. Find out more about the safety of tank water at the NSW Health website.

E.coli is present in high numbers in human and/or animal faeces and will be detected in almost half of all tanks tested . This test is useful in determining if maintenance on the tank and its catchment are adequate enough to capture good quality rainwater for consumption.

Chemical testing of  tank water will only be required in exceptional circumstances or if there are specific concerns. Tank owners should ensure that the tank and associated plumbing  have been manufactured specifically for the collection of rainwater and not stormwater as some PVC pipes may contain lead and other contaminants. For more information visit the NSW Health website

At the beginning of your lease you should be informed that rainwater is the source of drinking and household water and that maintenance responsibilities have been discussed. Please refer to the Fair Trading website for more details. Regularly inspect the tank, roofing and guttering and for more helpful advice refer to the NSW Health website.

The blueish water you may have noticed in the bathroom is a sign of corrosive water. The main problem with corrosive water is the slow chemical etching and consequential damage to plumbing &  hot water systems.  Ignoring the signs may result in an expensive repair bill &/or unnecessary consumption of toxic metals. The good news is that corrosive water can be corrected relatively simply with the installation of an alkaline filter between the tank and the house.

Most often, it is the saltiness of groundwater that will limit the drinkability. See NSW Health website for more information. Other factors to consider when deciding if groundwater is safe is the proximity of the well to septic, stockyards and dip sites. The bore should be capped to prevent surface water from over-topping.

Come see our friendly staff Monday to Friday 8.30am to 4.15pm. E.coli  samples must be received before 4pm Thursday.

Testing can take up to 10 working days, depending on the requirements. We will let you know when to expect results when you deliver the samples.

National Association of Testing Authorities. The core of NATA accreditation is the third party, objective, peer assessment process at a scientific and technical level that provides assurance of the facility’s capability to produce reliable data from particular analyses.

To check if the particles are widespread in your neighbourhood or confined to your tap, ask your neighbours if they are seeing them too. If the particles stick to your fingertips like black marker pen, investigate if the gasket in the tap hardware is degrading.

They could be bloodworms, which are harmless to humans and animals. Make sure the meshes are intact.

Coloured water might be attributed to the degradation of  household plumbing from soft water.

An oily sheen can  originate from natural sources. Test it by stirring with a stick. If the sheen comes back together immediately, it’s likely to be a petroleum product.

Drinking water supplied by Rocky Creek Dam and Emigrant Creek Dam to the Council areas of Lismore, Ballina, Byron and parts of Richmond Valley is relatively soft. Some dishwashers require a hardness value as an indication of the typical water value. In these locations, at this point in time, the value for hardness is less than 4 od.
