 The town government provides water and water treatment to 534 structures that are connected to a pair of wells.Darrington is one of several small communities in Snohomish County that lack a municipal sewer system, instead relying on septic tanks.The town government has considered installing a sewerage system several times in the 1990s and 2000s, but the $6.5 million cost (as estimated in 2000) and the needed land for a sewage treatment plant have caused plans to stall.
