EPA Regulated Water Systems 4Wastewater/Sewer City of Shoshone City of Shoshone Wastewater Treatment Facility Lagoon Drive Shoshone, ID 83352 The collection system and treatment works were constructed in the early 1970s. The facility was rst permitted in March of 1991 as a lagoon treatment facility with a design ow of 0.2 million gallons per day (mgd). The reissued permit (April 1, 2005) contained a compliance schedule for chlorine addition. The design ow was increased to 0.53 mgd.5 The collection system is comprised of ve lift stations. Four of the ve stations (#1, #2, #3, and #5) are duplex submersible stations with lead pump cycling. These four stations discharge to a cast iron force main with a 4-inch diameter discharge. Lift Station #4 is a wetwell station. This station discharges to an 8-inch diameter force main that transports euent to the WWTF. Two dual-pipe inverted siphons transport sewage under the Little Wood River. The Grape Street siphon carries sewage from a 15-inch gravity collector to the 6-inch and 10-inch siphons. The Birch Street siphon carries sewage from a 12-inch gravity sewer to 6-inch and 10-inch siphons. A replacement for the Grape Street sewer main was proposed in September 2008 and completed in spring of 2009.4500 I D A H O I N F R A S T R U C T U R E G U I D E B O O K'
