As kiwi families head for holiday homes and camping grounds this summer, Water New Zealand is urging people to make sure there are no hidden health risks lurking in the pipes.

Technical lead, drinking water and education, Belinda Cridge said many holiday spots rely on tank water so it’s important to ensure that drinking water is boiled to kill bugs that may have got into the tank through bird droppings or vermin.

She said it’s also important to remember that water that has been sitting in pipes for weeks or months can become stagnant and harbour other risks such as legionella pnuemophila and other bacteria.

“Bacteria like legionella can multiply in pipes left unused for just a week or two, making holiday homes and caravans particularly vulnerable.” 
  
She said these conditions carry risks, especially for children, older adults or people with immune deficiencies or underlying health issues.

“So before you pull out the barbeque, take a few minutes to ensure that you run all taps, showers and outdoor hoses to clear out any stagnant water.

“Flushing taps, ensuring hot water systems are set above 60 degrees to prevent bacterial growth and removing and cleaning shower heads to prevent bacteria or sediment build-up will help keep your family and friends safe.

“For drinking water safety, it’s important to run at least a cup full of water each morning to remove any lead from water that may have been sitting in pipes overnight, even if your holiday home is on a reticulated supply.

“As well, keep an eye out for any boil water notices from your council.  Many suppliers in small communities struggle to ensure safe drinking water. Boil water notices often indicate an e-coli contamination.”

Septic tanks can also pose a health risk.

“If your holiday spot relies on a septic tank, take a look at the area around the tank to check for any soggy ground, pooling water or bad odours.  This could indicate a leak or blockage.

“And remember the three p’s - only flush pee, poo and toilet paper and try to stagger water use, such as showers and laundry, to prevent overloading the septic tank system.

"We want people to enjoy their summer break without worrying about their water.  Taking a few minutes to check the water when you arrive can help ensure everyone has a happy holiday.”
