Sewer authority marks 40 years in Silverthorne, Dillon area

Daily News staff report

July 6 marked the 40th anniversary of the agreement that created the Silverthorne/Dillon Joint Sewer Authority.

On that date in 1971, Silverthorne and Dillon entered into a joint venture to construct and mutually use the Blue River Wastewater Treatment Plant and sewer interceptor system. Soon after, Dillon Valley and Buffalo Mountain signed agreements to participate in the JSA, and in 1980 Mesa Cortina signed a similar agreement.

The five entities that participate in the JSA share the cost of operating the joint facilities according to their share of the capacity that they have the right to use. Silverthorne has a 42 percent share, Dillon 21 percent, Buffalo Mountain 23 percent, Dillon Valley 11 percent and Mesa Cortina 3 percent. Before the creation of the JSA, each community operated its own wastewater treatment facilities. Dillon discharged sewage to a lagoon in Silverthorne at the current site of Rainbow Park. Silverthorne discharged to a lagoon still used today at the treatment plant as a flow equalization pond.

Engineer Ron McLaughlin and attorney Gordon Garrett were the architects of the original JSA agreements, and they both still serve the JSA today. The joint facilities have been expanded, pursuant to the 1971 agreement, to meet the needs of the communities it serves. The original treatment plant was designed to treat 1 million gallons of wastewater per day. Today, the treatment plant has the capacity to treat 4 million gallons per day.

Collectively, Silverthorne and Dillon are the governing body of the JSA. Silverthorne is designated as the lead agency and directs the day-to-day operations of the joint facilities.
