The main purpose of this Act is to ensure you get safe drinking water. This Act wants drinking water suppliers to have a plan to keep water safe. They must also follow rules about drinking water standards. This Act also wants to work with the Resource Management Act 1991 to manage risks to the water you drink. It aims to make sure the rules for drinking water are fair for each supplier. This means the rules will be based on the size and complexity of each water supply. This Act has other purposes too. It wants to make sure you know how well your drinking water, wastewater, and stormwater networks are performing. It also wants to help drinking water suppliers improve their skills and work together. You get enough drinking water to meet your needs. The Act aims to keep improving the quality of water services in New Zealand over time.
