The three long, deep-water intake pipes were built as part of the original DWLC project, commissioned in 2004. Access to deep cold water is an important benefit of the system, but you're correct that they have a dual purpose, and access to cleaner water for the municipal supply was presumably a side benefit. As part of a system expansion, they are currently building a 4th intake which would re-use one of the original, shallower municipal water intakes which was obsoleted by the 2004 system. This would be extended to reach colder water and would bypass the city water treatment plant to deliver raw water directly to the DLWC: https://www.toronto.ca/community-people/get-involved/public-consultations/infrastructure-projects/deep-lake-water-cooling-expansion-study/ https://www.toronto.ca/community-people/get-involved/public-...
