Water Hygiene
While rented premises are generally very low risk it is important to implement measures to assure the hygiene of the water supply.
This is because some diseases can be transmitted though inhaling water droplets contaminated by bacteria. Such diseases cannot be passed from one person to another or by drinking. This leaflet aims to give you information on what precautions you can take within your home.
The risk
There is a risk if your property is empty for long periods of time i.e. over two weeks. This can be due to long hospital admissions, extended holiday periods or any other reason. The greatest risk is where stagnant water is present between 20 and 45°C in tanks, infrequently used outlets, shower heads and air conditioning units.
People at risk
Some people are at higher risk than others, including:-
- People over 45 years of age
- Smokers and heavy drinkers
- Those suffering from chronic respiratory or kidney disease
- Anyone with an impaired immune system
Controlling and minimising the risk
There is a risk if your property is empty for long periods of time i.e. over two weeks. This can be due to long hospital admissions, extended holiday periods or any other reason. The greatest risk is where stagnant water is present between 20 and 45°C in tanks, infrequently used outlets, shower heads and air conditioning units.
Below shows what you can do to maintain hygiene at an acceptable level.
Water outlets from mains supply
