ENSURING WATER IS SAFE
When turning on a tap, most people do not question the quality of the water they’re pouring into a glass. Even more remote is the thought that the water they’re about to drink could lead to serious illness or possibly death. People who have engaged a registered certifying plumber should have every confidence that the water supply delivered to them is safe.
However. A recent disciplinary case heard by the Board, underpins the need to remind certifying plumbers to review their approach to the delivery of water to consumers by ensuring that:
• Every effort is taken to verify the source of the water supply;
• The method of installation meets or exceeds minimum compliance standards;
• Appropriate testing and commissioning of installations is undertaken.
In the recent case heard by the Board, a senior certifying plumber failed to verify that the tank that he was installing which was to supply water to a rural café, was fit and safe for the storage of potable water. In fact the tank had previously been used to hold human waste and caused a significant public health issue.
In urbanized areas throughout New Zealand, water is collected by councils and supplied to homes and businesses through reticulated water mains. Councils are responsible for ensuring reticulated water is safe for use. However, in rural areas, without access to reticulated three
In any design, remember the three steps
to safety:
1. Verify the source of the water (e.g. river, roof catchment or bore)
2. Test the water to determine the appropriate treatment requirements for the intended use of the water e.g. for potable water send a sample to an accredited testing facility - their report will indicate if it’s necessary to incorporate a water treatment device (e.g. filtration, ultraviolet, water dosing) in the
design
3. At a minimum install, test and commission the system according to the requirements outlined in the NZ Building Code G12 (3rd
edition)
