City of Calgary - Request for Proposal - 26-1602 City of Calgary Potable Water Quality Improvement Initiative and Chlorine Boosting Strategy

The City of Calgary is soliciting proposals from qualified consulting firms to support its Water Quality Improvement Initiative, specifically focused on enhancing chlorine residual management and overall potable water quality across the municipal water system. This planning-level engagement will not involve design, construction, or implementation but will center on assessment, modeling, and decision support to provide a robust, evidence-based foundation for future operational and capital planning. Proposals must address one or both of two distinct work packages: Work Package A includes a jurisdictional review of industry best practices, development of a standardized monitoring and management framework for chlorine residuals, and an assessment of the City’s current performance to identify improvement alternatives; Work Package B involves the development of a system-wide water quality model to simulate chlorine residual behavior. Each work package will be evaluated independently using criteria outlined in the solicitation, and awards will be issued separately, allowing a single firm to win both packages or different firms to be selected for each. Proposals must be submitted by July 8, 2026, and must clearly label which work package(s) are being addressed to ensure proper evaluation. The solicitation, identified as AB-2026-04231 under NAICS code 541620, is open to firms with demonstrated capability in multi-disciplinary consulting services related to water quality modeling, regulatory compliance, and system performance analysis. The contracting authority is Khalil Choudhry, and all submissions must be directed through the designated channels on CanadaBuys. While the place of performance is in Alberta, the solicitation is issued by the City of Calgary, not a federal agency, despite the organizational classification listed. Responses will be assessed on technical merit, experience, methodology, and proposed approach, with the goal of selecting partners who can deliver actionable, scientifically grounded recommendations to strengthen the integrity and reliability of the City’s drinking water system.
