Another preliminary data product is a spreadsheet that links settlement areas with the wastewater treatment plant that serves it and indicates whether the settlement area is served by municipal wastewater treatment or a private sceptic system.
Updated profile information and other data sets from MOECC and Environment and Climate Change Canada would make creating spreadsheets like this much easier and less time-consuming to prepare. Linking these data to flow data would also allow for a high-level assessment of plant capacity in relation to planned settlement areas. It would also be helpful to include settlements served by large subsurface sewage disposal systems, since these systems may affect groundwater quality.
