Common questions
Who is my water provider in Centennial, Colorado?
Centennial, Colorado is served by 4 community water systems, not one: Southgate Water & Sanitation District, Arapahoe County Water & Wastewater Authority, East Cherry Creek Valley Water & Sanitation District and 1 more. Which one serves a given house depends on the address.
Why does Centennial have more than one water provider?
Service areas follow districts and annexations, not town limits, so a town is often split between several systems, and a wholesaler's area can overlay the retail system that buys from it. The address lookup on this page settles which one covers a given point.
