The Warm Springs Water District is about 2 miles west of Dubois, and has 42 taps. The area is experiencing substantial growth. There are 99 lots in the district and another hundred in the plat. The existing system has had occasional bacteria problems in the past, and has had freezing problems in main lines. The system was unable to supply existing demands in the winters of 92-93 and 93-94. A new source is needed to meet both existing and future demands, and to resolve water quality problems. The existing storage system is inefficient and inhibits disinfection. The distribution system is in good shape with only minor losses.

A Level II study inventoried the existing water supply system and identified needed improvements. The study also considered several supply alternatives including rehabilitation of the existing infiltration gallery, other springs in the area, a deep well and pumping from the Dubois area. The existing source cannot be improved to increase the supply and no other usable spring sources were identified.

The 1994 project constructed a 700 foot-deep Madison well on district property. The well is projected to yield in excess of 500 gpm. The water is somewhat warm (80 degrees) and very hard (700 ppm TDS). The 1995 appropriation was used to convert the test well to a production well and perform additional water quantity and quality tests.

The 1996 Level III recommended project will convert the test well to production status, construct a new storage tank, loop the system and provide the pipelines necessary to incorporate the new well into the existing system. Construction should be complete in December 1997, except for seeding and reclamation which can be done in the spring of 1998.

No legislative action is required.
