Water Whys

Why do we have a large number of water supply reservoirs, service basins and other storage basins located throughout our service area?


Reservoirs and supply basins allow sediments to settle out, and contact with wind and sunlight cause pathogens to die off.

They also provide enough storage to meet the summer water needs under normal conditions, filling over the winter and being drawn upon during summer.

Service basins

Our service basins are smaller than the supply basins and are located upstream of our water treatment plants.

They provide balancing storage to meet peak daily demands and allow us to store emergency supplies of water for individual townships.

Clear water basins

These storages, as their name implies, are used to store water that has been filtered.
