Your water usage – restrictions and tips for water conservation
We buy treated water from the Greater Wellington Regional Council and distribute it to you via our network of 685 km of underground pipes, 24 storage reservoirs and 13 pumping stations, making sure it meets the Ministry of Health’s drinking water standards.
We all have a part to play in conserving water, especially in the garden and during the hot summer months.
Visit the Greater Wellington water conservation page for water-saving ideas.
Using water in summer – restrictions and tips
Summer’s temperatures and dry winds increase evaporation, and there’s less rain, which increases water usage and can mean water shortages.
To make sure there’s enough water for everyone, we restrict the use of sprinklers and unattended garden hoses when daylight saving is in place.
When can I use my sprinkler or unattended garden hose?
- You can only use your sprinkler every other day (if you have an even-numbered address you can water on even days of the month, and on odd days if you live at an odd-numbered address)
- On these days you can use your sprinkler between 6-8am and 7-9pm
- You can use a hand-held hose at any time
These restrictions apply to all properties on ‘town’ supply in the Lower Hutt. You can keep an eye on how water use is trending in your area on Wellington Water's website.
Saving water in the garden
As well as following garden watering restrictions during daylight saving, there are a number of steps you can take to save water in your garden.
- Use good mulch – it holds water and protects the soil from drying out
- Remove weeds – they compete for water
- Use your broom for sweeping, not your hose – using your hose to ‘sweep’ uses 1,000 litres of water per hour, while your broom uses none!

What else can I do to save water?
You can help protect the water supply system and our environment by:
- Making sure your plumbing system is compliant and in good condition – this reduces water wastage and health risks
- Observing the publicly notified water supply restrictions on garden watering during daylight saving
- Being careful with any public water supply pipes which pass through your property and making sure we’re able to access the pipes if we need to
- Letting us know about water leakage or waste and any unauthorised use of fire hydrants or storage reservoir roofs
By taking these steps you can help maintain the safety of our water supply system and minimise future costs to ratepayers.
What belongs to the council and what belongs to you?
You are responsible for all water supply plumbing fittings on your property after our ‘point of service’.
What and where is the point of service?
This is the shut-off valve (known as a toby) which is situated on or close to the street boundary of your property. We’re responsible for maintaining the water supply system up to and including the point of service.
