GMF loan supports innovative sludge processing plant in Gatineau RCM

KAZABAZUA, QUE-A one-million-dollar loan from the Green Municipal Fund has enabled the Regional County Municipality (RCM) of La Vallée-de-la-Gatineau to build and put into successful operation of an innovative septic tank sludge collection system project. At the RCM's Centre de traitement et de valorisation des boues de fosses septiques, the septic tank sludge is dehydrated using rotary press technology, which separates liquids from solid matter. Liquids are sent to aeration tanks, while the residual sludge is mixed with forest waste to produce compost. "We take water quality seriously," said RCM warden Pierre Rondeau. "That is why we have installed an integrated management system for sludge collection centred at our new processing centre. We estimate that the project will reduce air pollution caused by transportation and reduce greenhouse gas emissions in the order of 200 tonnes a year." The RCM of La Vallée-de-la-Gatineau, about 40 kilometres north of the city of Gatineau (opposite Ottawa), comprises 17 municipalities and covers 13,424 square kilometres, making it one of Quebec's largest RCMs.
