The surface water bodies around Christchurch are receiving untreated sewerage because of the many broken sewer pipes around the city. This means you need to keep your family (and dogs) away from water until further notice.
Don’t forget that your dogs require their water to be boiled as well. (Even if you have mains water supply, the Council wants you to boil water until further notice.) It is recommended that you boil water for 3 minutes, allow it to settle and cool, and then re-boil for another 3 minutes.
Take care out there.
