Waterworks Utility Annual Report 2020 This report summarizes the City of Vancouver Waterworks Utility activities and program outcomes for 2020. It provides a financial synopsis for the year, and gives detailed information on Waterworks performance in programs for: Water Quality; Water Conservation; Capital Asset Management, and; Asset Operations & Maintenance. In 2020, a new strain of coronavirus called COVID-19 reached the City of Vancouver. This report includes details on related operational challenges and opportunities as Waterworks staff adapted to new health and safety protocols and continued to work diligently to monitor water quality, minimize water waste, maintain Vancouver’s drinking water system, and to ensure the delivery of over 100 billion litres of safe, high quality drinking water to our customers. This report is posted on the City’s website to assure the public of the excellent quality of Vancouver’s drinking water, and to promote the programs and activities supporting continuous delivery of clean, safe drinking water to Vancouver customers. Provincial regulations governing water suppliers in British Columbia require the City of Vancouver to conduct drinking water quality monitoring and publicly post the results within 6 months of year- end. This report satisfies those requirements. 2020 Report Statistics at a Glance • Waterworks delivered 108.5 billion litres of drinking water throughout Vancouver. • The drinking water quality met or exceeded Provincial Regulatory requirements, Health Canada standards and relevant International best practices. • Water conservation policies and projects resulted in a 26% decrease of potable water use from 2006 rates. • 8.6 kilometres of water mains were replaced, and 0.2 kilometres of new water mains were constructed. • 10 temporary handwashing stations, 9 temporary drinking fountains and 13 temporary misting stations were deployed strategically to increase access to water for vulnerable populations.
