A Review of the Impacts of Municipal Wastewater Effluents on Canadian Waters and Human Health was published in 1997. The report identified the status of municipal wastewater effluents in Canada and identified the main concerns in terms of human health and environmental effects. A full report of this review is available in the following publication: Chambers et al., 1997, "Impacts of municipal wastewater effluents in Canadian waters: A review", Water Quality Research Journal of Canada, 32(4):659-713. (English only)
For the following documents only executive summaries are currently available through this website. Please contact the Municipal Wastewater Effluent Division to receive a CD with Word or PDF versions of the complete documents. Links to obtain complete electronic versions and hard copies are projected to be available in winter 2005 and will be provided on this page.
Environment Canada's Review of Municipal Effluent Chlorination/ Dechlorination Principles, Technologies and Practices was published in March 2003. The report includes a comprehensive review of the current state-of-the-art methods for chlorine-based disinfection, residual chlorine control, dechlorination chemicals and procedures, and the related chlorination and dechlorination equipment used in the wastewater treatment.
The Ultraviolet Disinfection Guidance Manual for Municipal Wastewater Treatment Plants in Canada was published in October 2003. The manual reviews ultraviolet disinfection technology and advancements for application in disinfecting effluents from municipal wastewater treatment plants (WWTPs). This manual's purpose is to provide information and guidance to communities investigating UV technology for application at their wastewater plants.
The Treatment Processes for the Removal of Ammonia from Municipal Wastewater document was published in 2003. The manual describes techniques to identify and evaluate technological options for application at municipal wastewater treatment plants (MWWTPs) for the removal of total ammonia-nitrogen (the sum of un-ionized ammonia-nitrogen and ammonium nitrogen) from wastewaters. The report is intended to serve as a reference and decision-support tool to assist municipal engineers, managers and senior process staff at MWWTPs.
The Guidance Manual for Sewage Treatment Plant Process Audits is a reference document for agencies, municipalities, consultants, planners, organizations, and individuals responsible for the assessment, optimization, and upgrading of municipal sewage treatment plants. It focuses on technical methodologies that have been used to examine and assess full scale plants. In particular, conventional and modified activated sludge facilities are covered in detail.
