Water Restriction Level 1 is now in effect across Wellington City, Lower Hutt and Porirua, joining Upper Hutt and South Wairarapa who are in Level 1 year-round.

Water Restriction Level 1 asks people to use sprinklers every second day.

If you live in an even numbered house, you can use sprinklers or irrigation systems on even numbered days between 6-8am and 7-9pm. If you live in an odd numbered house, the same rules apply for odd numbered days.
Faq / The Treatment Process

The treatment process

All treatment plants are slightly different, but the process is generally similar.

Entering the treatment plant.

As wastewater enters a treatment plant it is passed through milliscreens. These are made of fine mesh (about two millimetre wide openings) and act as a sieve to stop any large solids in the wastewater getting through, such as wet-wipes, sanitary products, shampoo bottles, toys, plastic bags, etc (link to "Looking after your wastewater" page). Everything that doesn’t make it through the screens is collected, pressed to squeeze out the excess water, and then transported to a landfill. The liquid that does make it through the milliscreens then flows through a pipeline into an aeration basin.
