SUPERVISION OF ACCESS• Depending on how situation evolves, access to flood

DRINKING WATER

Rising water levels do not affect drinking water supply or quality ofwater distributed through supply network.


Residents with access to well water are responsible for setting aside a supplyof drinking water and for following up with the water treatment serviceduring recovery phase to ensure water is drinkable.

SEPTIC TANKSIn order to limit pollution and septic tank backflow following flooding, municipal authorities will mandate a specialized company to carry out selective emptying of sludge. This method removes sludge from tank, but does not empty tank completely, thus preventing a violent expulsion of contents when water table recedes.

Work will be carried out as soon as possible after water recedes.
