UV Water Filter Service Mangawhai for Safe, E. coli-Free Water
From Mangawhai Heads to Kaiwaka.
Protect your drinking water with UV water filter servicing in Mangawhai
Mangawhai has no council water supply, so almost every home, bach and business relies on rainwater tanks. Your UV system is what stands between the water in your tank and the water your family drinks.
We look after UV systems across Mangawhai Village, Mangawhai Heads, Langs Beach and Te Arai, plus the lifestyle blocks around Kaiwaka and Hakaru. Every 12-month UV water filter service includes a new UV lamp, the quartz sleeve taken out and cleaned, new filters, a check of the controller, and sterilising the water lines into your home. It’s covered by the Aqua Works Guarantee, and we remind you when your next service is due.
UV water treatment is your first line of defence
Coastal roofs collect more than rain. Seagull droppings, salt, sand and leaves all end up in the gutters, and bacteria such as E. coli can wash straight into your tank.
UV light kills those bacteria in seconds, without chemicals. The lamp loses strength over 12 months even though it keeps glowing, so it needs replacing every year to keep your water safe.

Recent UV jobs in Mangawhai
A few of the UV systems we’ve installed and looked after around Mangawhai.
Moirs Point Christian Camp
For the camp’s new bush camp for kids, we fitted a new NSF-validated Viqua Pro UV system with filtration and upgraded the water pumps. We also moved the camp’s existing Viqua Pro system into a new shed, so the whole setup is tidy, compact and meets code.
Marram Place, Mangawhai Heads
A new home on tank water. We installed the water tank, the water pump and suction line, and a whole-house Aqua UV system, and connected the downpipes to the tank and its overflow.
We also designed and installed the water pumps, UV and filtration for Northbase, the new commercial development in Mangawhai.
UV servicing for Mangawhai homes and baches
Safe water at every tap, all year round
Local UV Water Filter Servicing in Mangawhai
Mangawhai is growing fast, and many new homes come with a UV system that nobody has booked in for its first service. If you’ve bought a new build or moved into an existing home, check when the UV lamp was last replaced. If you don’t know, it’s time for a service.
Holiday homes need care too. If your bach sits empty for weeks, leave the UV system switched on. If the power has been off while you were away, run the taps for a few minutes once the UV has warmed up, before you drink the water.
Your 12-month UV service
Every service includes a new UV lamp, the quartz sleeve taken out and cleaned, new filters, a check of the controller and your water pressure, and sterilising the water lines into your home.
Your system is then covered by the Aqua Works Guarantee, and we remind you when the next service is due.
Emergency UV Water Filter Service Mangawhai
If your UV alarm is beeping, the lamp has gone out or the system has stopped working, your tank water is no longer being disinfected. Until it’s fixed, boil your water before drinking it or cooking with it.
Our vans carry UV lamps, quartz sleeves and controllers, so most faults can be fixed on the first visit. We cover Mangawhai, Mangawhai Heads, Langs Beach, Te Arai, Kaiwaka and Waipu.

⭐⭐⭐⭐⭐
“We have an advanced rain water treatment system at our Mangawhai Heads home which includes whole house neutralisation, UV treatment and 3-stage filtration with KDF/GAC, primarily for removal of copper contamination from gutters and down pipes. The system was supplied and installed by Aqua Works and has just had its first annual service by them.
We have been totally satisfied with the expert service throughout and it has been a pleasure dealing with an efficient organisation who have always seemed to our best interests at heart. We are looking forward to a long association with Aqua Works.”

FAQ about UV Water Filter Service in Mangawhai
Mangawhai has no town water supply. Do we need UV on our rainwater tank?
We strongly recommend it. With no council supply, your rainwater tank is your drinking water. Birds, salt spray, leaves and dust on a coastal roof can all carry bacteria into the tank.
A UV system, fitted after a sediment filter, kills bacteria such as E. coli before the water reaches your taps. It’s the final barrier in a whole-house water treatment system.
How often should a UV water filter be serviced in Mangawhai?
Every 12 months. The lamp keeps glowing long after it stops producing enough UV light to protect you. Spring is a good time to book, so your system is ready before summer guests arrive.
We’ll add you to our reminder list, so you never miss a service. Call Raewyn on 0800 278 296 to book.
We've had water delivered by a tanker. Is our water still safe?
Delivered water should come from a registered water carrier, but filling the tank stirs up the sediment on the bottom. Cloudy water shields bacteria from the UV light, so the UV can’t do its job properly.
After a delivery, check your sediment pre-filter and replace it if it’s dirty. If the water stays cloudy or the UV alarm comes on, call us before you drink it.
Our Mangawhai Heads bach sits empty for weeks. Should we turn the UV off?
No, leave it switched on. UV lamps are designed to run all the time, and switching them on and off shortens their life. Water that flows through while the UV is off isn’t treated either.
If the power has been off while you were away, run your taps for a few minutes once the UV has warmed up. If you’d like your service done while you’re not there, talk to us about access.
We've bought a new build in Mangawhai. When does the UV need its first service?
Twelve months after it was installed. Many new homes have a UV system that nobody has booked in for its first service, so check the install date on the unit or ask your builder.
If you’re not sure, book a service. We’ll check the lamp, sleeve and filters, and add you to our annual reminder list.

We service UV systems in Mangawhai Village, Mangawhai Heads, Mangawhai Central, Langs Beach, Te Arai, Kaiwaka, Hakaru and Waipu.

Yes. We offer laboratory testing for E. coli, total coliforms and other contaminants, and we can take the sample during your UV service.
Call Raewyn on 0800 278 296 to order a water test.
