*Residents are asked to ensure their sump pumps do not discharge into the sewer system, which is a contributing factor in sewage bypassing.  As an incentive to install sewer backflow prevention valves in residential buildings, the Municipality offers a Sewage Water Alleviation Grant to offset material and labour costs. For applications, contact the Public Services Department at 854-1100 ext. 2029.

Public Notification for Sewage By-Pass Events in the Geraldton and Longlac Wards is carried out as per procedure approved by the Thunder Bay District Health Unit and the Ministry of the Environment.   The procedure for beach sampling is recommended in case of by-pass event(s) into the waterways - Kenogamisis Lake and Hard Rock Creek in the Geraldton Ward and Making Ground River and Long Lake in the Longlac Ward; as coordinated by the Public Works division of The Corporation of the Municipality of Greenstone and the Ontario Clean Water Agency.  Public notice of extended by-pass events will be communicated via radio announcements and posting on the municipal website, in addition to the regular notification procedures.
