ASSESSING Urban DENSIFICATION IMPACTS ON WATER DEMANDS in metro Vancouver

transect.jpg

This project used GIS and data analysis methods combined with residential water use modelling to define the projected impact of urban densification on residential water demands in Metro Vancouver.

The project included:

  • detailed analysis of current demands from meter data, census data, lot areas and irrigable areas to develop current unit rates

  • developing GIS-based residential land use and population forecasts

  • Examining case studies to confirm lot-level water demands

  • Combining the unit rates and residential forecasts to estimate yr-2041 demand

  • Identifying the potential effects of five water conservation initiatives: high-efficiency toilet rebates, clothes washer rebates, grey water re-use, native plants landscaping, and increasing topsoil depths
