From The Crested Butte News (Mark Reaman):
The Crested Butte Town Council and staff batted about different views at the Tuesday, August 3 meeting. Town public works director Rodney Due took the position of trying to keep out a proliferation of ISDSs (individual sewage disposal systems) around the town and nearby wetlands. “I think it is necessary from an environmental impact standpoint to try and not have ISDSs near town,” Due said.
Under an ordinance to be considered by the council, water lines would be extended outside of town only to utilities, governmental or quasi-governmental entities. Tap fees would be one and a half times the in-town rate and monthly fees would be twice the rate. The ordinance would allow residences and accessory dwellings to tap into the sewer system of Crested Butte. The sewage tap fees would be one and a half times the in-town rate and the monthly fee would be twice the in-town rate.
