Commercial Water Treatment
Safe, compliant water for your business.
Water treatment and filtration built for business
We design, install and service water treatment for businesses across Rodney and North Auckland: cafés, schools, farms, campgrounds, workplaces, accommodation and more.
We take care of the whole job: onsite appraisal, accredited lab testing, system design, installation, registration and ongoing servicing. Owners get one point of contact. Architects, specifiers and project managers get a system designed to the rules, with the documentation to match. See commercial water supply systems.
Key dates: if your business supplies drinking water from its own tank, bore, spring or stream, it’s a drinking water supplier. Existing supplies must register with Taumata Arowai by November 2028 and fully comply by 2030. New supplies must register before they start.

Is your business a drinking water supplier?
If your business gives drinking water to staff, customers or the public from its own source, the answer is usually yes. That includes small businesses.
- Supplies that are only for household use, for 25 people or fewer, don’t need to register
- Business, community and public supplies do, whatever their size
- Existing supplies: register by November 2028 and fully comply by 2030
- New supplies: register before you start supplying water
Most small business supplies can comply with an Acceptable Solution. Others follow the Quality Assurance Rules and need a Drinking Water Safety Plan. Find out more about drinking water suppliers.

“Have used Steve and the Aqua works team for many years for our water filtration needs. Great service, great product, and exceptional after sales service also. They come highly recommended.”
Andrew, HomeSolutions Real Estate, 2024
⭐⭐⭐⭐⭐
“We have had Aqua Works at our property to install a new water tank with a new pump and water filters. That went so well that we have also been calling on them for all the plumbing work needed during our renovations. Troy has been our plumber and he is professional, reliable, clever and so personable to have around, which makes a real difference when you have a lot of work to do. We would highly recommend Aqua Works, they will be our go-to for all plumbing work from now on.”

Commercial water treatment FAQs
Is my business a drinking water supplier?
Usually yes, if your business gives drinking water to staff, customers or the public from its own tank, bore, spring or stream. Find out more about drinking water suppliers.
Do small businesses need to register their drinking water supply?
Yes. Only supplies that are just for household use, for 25 people or fewer, are exempt. A business, community or public supply needs to register, whatever its size.
When does a business need to register its drinking water supply?
Supplies operating before 15 November 2021 have until November 2028 to register and until 2030 to fully comply. New supplies must register before they start operating.
Does our business need a validated UV system?
Under the Self-supplied Buildings Acceptable Solution, yes if more than 25 people use the water, or it’s available to the public or has a community purpose. UV installed before 17 October 2022 is exempt if you have written proof it delivers 40 mJ/cm².
What’s the difference between an Acceptable Solution and a Drinking Water Safety Plan?
An Acceptable Solution is a ready-made way to comply: you follow its set design and don’t need your own plan. If your supply doesn’t fit one, you follow the Quality Assurance Rules and need a Drinking Water Safety Plan.
What water treatment does a business usually need?
Most supplies need filtration and UV. Some also need reverse osmosis, a softener or iron removal. We test your water first, so we only install what it needs. See commercial water softeners and filters.
Can Aqua Works work with our architect or project manager on a commercial water system?
Yes. We can provide a system design, product data sheets, UV validation certificates and a service plan, and coordinate installation with the other trades on site. See commercial water supply.
Can Aqua Works install and service water treatment around our trading hours?
Yes. We plan installations and servicing for quieter times to keep downtime to a minimum, and our 24/7 emergency team is on call if something goes wrong.
How often does a commercial water treatment system need servicing?
Change UV lamps as the manufacturer recommends, usually once a year, and replace filters regularly. We can set up a service plan and keep the records you need.
Where does Aqua Works install commercial water treatment?
Across Rodney and North Auckland, from Mangawhai to Albany, including Warkworth, Matakana, the Hibiscus Coast and Dairy Flat.
Safe water, and compliant by 2030
Businesses on their own water must register by November 2028 and fully comply by 2030. Book an onsite appraisal and we’ll get your supply ready, then look after it for you.
