EXECUTIVE SUMMARY
This 2003 Drainage Master Plan outlines the strategic direction for Drainage Services foplan is a continuation of the direction established with the 1991 City Council approvedthe 1991 plan, key areas identified were: protection of existing homes from basement environmental protection, and accommodation of new development. Since that time,developed a number of strategies to address these issues, including the Sanitary ServicCity Council in July 1998, and the Combined Sewer Overflow Strategy approved by City
The 2003 Drainage Master Plan identifies current issues and describes strategies to addissues identified include: Total Loadings to the North Saskatchewan River, New Water Regional Servicing, Membrane Filtration, Industrial Land Development, CommunicationInfrastructure Rehabilitation/Maintenance. These issues were identified through a sermeetings with the following groups and stakeholders: Drainage Master Plan Working CoServices management, an outside expert advisory group, and the representatives from Technical Advisory Committee.
In the near term, it is not anticipated that the issues identified will have a significant Services 20-year financial Capital Priorities Plan. However, a few of the issues have thfunding gaps should conditions change from what is known today. These issues includeMembrane Filtration, and stormwater management facilities for industrial land develo
In July 2002, City Council approved the Land Drainage Utility, a significant step for Drautility, implemented January 1, 2003, will allow Drainage Services to develop long-terfor stormwater management projects. However, funding gaps remain as demands excopportunity exists to further improve water quality in the North Saskatchewan River, wdevelopment of a water recycling distribution network driven by industrial and irrigati
Guided by this Drainage Master Plan, Drainage Services looks forward to taking on the decade and beyond.
