Water supply studies require bringing together a water model of a basin, a sub-basin or a property to know the client needs and the water resources available.  Clearwater builds a water balance spreadsheet including the estimated volumes of surface inflow (rain, streams, springs) and underground resources (groundwater) and the surface and subsurface outflow.  The result is  a sustainable water model for the project site.

Geology maps and cross-sections, precipitation maps and fault maps, as well as field inspections and a review of published well and geologic data are used to develop sustainable water supply programs.
