Holidaymakers are being urged to check the safety of their drinking water this summer.

Many small and rural communities, including some council-supplied water schemes, don’t have the same level of safety and treatment as large urban systems, Water New Zealand chief executive Gillian Blythe said.

“There has been some improvement in publicly supplied water. More councils now have sufficient treatment in place to protect against protozoa and bacterial infection.

“However, almost 400,000 New Zealanders are still receiving water from council supplies that lack one or more critical barriers to safety.“

With many small communities relying on tank and ground water, Blythe said it’s important water from these sources was treated or boiled before use.

“Tank water at holiday homes and campsites can easily be contaminated by vermin or bird droppings,” she said.

“If your water is from a public or council supply, keep an eye out for boil water notices.”

When a boil water notice was issued, it means E. coli had been found, usually from faecal contamination.

“No one wants their holiday spoiled by illness and a few simple measures can prevent unnecessary grief.”

Blythe said there’s also a risk when swimming in rivers, lakes, or at the beach, especially in the two to three days following heavy rainfall, when runoff and sewage overflows can cause E. coli contamination.“

It’s a good idea to check the LAWA (Land Air Water Aotearoa) website for information on the quality of water in your region and at your swimming spot.

The Water Services Authority Taumata Arowai recently launched an information campaign aimed at ensuring that camping ground and campsite operators understand risks and can meet their responsibilities when supplying drinking water.

“We welcome this initiative because everyone providing water has a duty to ensure it is safe.

“Ultimately, a few simple precautions can help ensure a safe and enjoyable summer holiday for everyone.”
