We use five levels of water restrictions depending on the time of year and any incidents in the community:
Note: levels one and two apply to domestic use, e.g. all residential customers, and all non-commercial use at commercial premises (for instance, a business may not use an irrigation system or sprinklers to water grass or flowers that are not for sale). Normal and typical commercial use of water is permitted. All customers are encouraged to reduce water consumption.
Level one water restrictions are in place from 1 January to 31 March every year unless circumstances require the summer restrictions to start earlier.
The Ministry of Health advises that some plumbing fittings have the potential to allow minute traces of metals to accumulate in water standing in the fittings for several hours.
Although the health risk is small, the Ministry recommends that you flush a mug full of water from your drinking-water tap each morning before use to remove any metals that may have dissolved from the plumbing fittings.
The Ministry is recommending this simple precaution for all households in New Zealand, including those on public and private water supplies.
This advice is provided throughout the country.
