Latest information about essential services following today's earthquakes in Christchurch.
The Canterbury District Health Board is advising residents to boil or treat all water from taps and tankers before drinking, brushing teeth or using in food preparation.
- Bringing water to the boil is sufficient to kill bugs. Water needs to be boiled even if the smell or taste of chlorine is present. If you cannot boil water, treat it by adding 1 teaspoon of household bleach per 10 litres of water and leave for 30 minutes.
- The City Council and Public Health are working together to test water supplies in Christchurch and will update this advice as soon as we have a clear idea of how the water supply has been impacted by the aftershocks.
- Employers should also make sure their staff are only consuming boiled or bottled water at work. This applies even for workplaces with self-supplied water, until testing can be completed and the supply can be cleared of risk.
- People should avoid sewage even if it is on their properties. They should also avoid contact with silt and waterways that may have been contaminated with sewage.
- Wash your hands or use hand sanitiser often, particularly after toileting, and before and after eating or preparing food.
- Most General Practice and pharmacies in the city are open. If you need medical assistance contact your usual General Practice in the first instance. If you telephone your usual General Practice team day or night a registered nurse will answer and provide health advice about where to go for treatment if required.
The CDHB also advises residents to keep warm above all else - particularly if there are elderly, chronically ill or young people in your household. If residents do not have electricity at this stage, make plans to stay warm tonight by using heating units that do not rely on electricity (such as flue gas heaters) or arrange to stay with friends or family with power.
Do not stay in your home if it is not weather tight, and make sure your family dress warmly even when inside.
