Community Statistics & Population Storm Prairie is located in Buffalo County, Minnesota. Incorporated in 1869, the economy was based on agriculture and light industry. A recent distribution center has added 40 new full time jobs. The company is expecting to double the number of employees in the next five years. Current Population: 1291 Current Households: 515 Projected 2020 Population: 1345 2015 Median Household Income: $41,352 D R I N K I N G W A T E R R E V O L V I N G F U N D System description General The public water system consists of two municipal wells, an iron & manganese filtration plant, one elevated storage tank, and a distribution system that serves all developed properties within the corporate city limits. The average water use in 2017 was 240,050 gpd, and the maximum water use was 552,114 gpd. All service connections are metered. Supply Well #2 is a shallow drift well, approximately 75 feet deep. In the last eight years the production has declined from 180 to 130 gallons per minute. Well #1 was sealed when Well #2 was drilled. Well #4 replaced Well #3 which also was sealed. Well #4 draws water from the Jordan formation. The water is high in iron and manganese.

Well Information Well Constructed Depth Capacity #2 1948 85 Feet 130 GPM #4 1964 208 Feet 260 GPM

Treatment The iron & manganese filtration plant was built in 1966. It consists of aeration followed by filtration in a steel, two-cell filter bed. Each bed has a capacity of 200 gpm. Only water from Well #4 goes through the treatment plant. Water from Well #2 is blended with the discharge from the plant before entering the distribution system. Chemical treatment consists of potassium permanganate, chlorine, and fluoride.

Storage Water is stored in a 300,000 gallon elevated storage tank located on Park Street. It was built in 1992. It is in good condition, with an inspection and possible recoating due in the next five years.

Distribution The community is serviced by cast iron and ductile iron watermain. Most lines are four, six, and eight inches in diameter. The cast iron lines are primarily in the central area of town and were installed in the early 1930’s. There are some two inch lines on the east side. The ductile iron watermain, installed in the 1970’s, is located on the north and south sides of town. Need for Improvements Source Well #2 is nearing the end of its useful service. Capacity has declined 28%. In 1998 the well was rehabilitated and production went up, but it has since declined to its current level of 130 gallons per minute. D R I N K I N G W A T E R R E V O L V I N G F U N D The Minnesota Department of Health recommends a community have pumping capacity equal to the average daily consumption with the largest well out of production. Storm Prairie does not meet this standard if Well #4 is not in operation. The city is planning on completing its well head protection plan in two years, then constructing a new well. They would like to be able to provide a reliable quantity of water that is low in iron and manganese.

Treatment The finished water is not in compliance with the secondary drinking water standards. The treatment plant is old, equipment is crowded, and the plant has never been dehumidified. Pipes are corroded, and the filter equipment has severe pitting. Filter media needs to be replaced, and the gas chlorine room is not in compliance with current safety standards. The city is planning on repairing or replacing the treatment plant in five years.

Watermain The city is planning on repaving Main Street next year. The Main Street watermain was installed in the early 1930’s and is old, brittle, and leaking, and is approaching the end of its useful life. Numerous repairs have been made to the cast iron watermain on Main Street because it is deteriorating. Now would be an advantageous time to replace the line. The city would also like to eliminate several dead end water lines on the south side of town. Numerous complaints associated with stagnant water have been received from residents on Third Avenue and on the south side of town. Alternatives The city has decided to address the distribution system problems at this time. Intentions are to address the supply and treatment problems in the next 2 – 5 years. The following alternatives were evaluated for the watermain distribution system: 1. Loop the dead end watermains to provide better water quality. 2. Replace the old cast iron watermain under Main Street when the street repair is being done. 3. Do nothing and people will continue to complain. Repairs will be ongoing for the Main Street. Replacement costs will increase after Main Street has been repaved. D R I N K I N G W A T E R R E V O L V I N G F U N D Alternative Selected Implement all watermain replacement and looping tasks in one year. The project would consist of (see attached map):

1. Replacing Main Street watermain from Mill Street to Winnebago a. (approx. 2,160 feet of 10” watermain) est. $732,000 2. Watermain Looping: Garden Street, west side a. (approx.. 990 feet of 6” watermain) est. $624,000 b. Garden Street to 10th Ave. S (approx. 180 feet of 6” watermain) est. $53,240 c. 10th Ave. between Washington & Lake (approx. 180 feet of 6” watermain) est. $53,240 d. Lincoln S. to Harrison S. (approx. 390 feet of 6” watermain) est. $102,850 e. 3rd Ave N to Highway 106 (approx. 900 feet of 8” watermain) est. $174,250 Cost Break Down Excavation and Labor $739,580 Pipe, fittings, valves, etc. $1,000,000 $1,739,580

Construction contingency $173,958 Engineering, admin., legal $233,958 $407,916

Total $2,147,496 Project Schedule Engineering Plans and Specifications: February 2018 Bid Project: March 2018 Award Contract: April 2018 Begin Construction: May 2018 End Construction: September 2018 Water Supply Plan A plan was submitted to the Minnesota Department of Natural Resources in June 2016. It is currently under review. Miscellaneous A city map is attached. D R I N K I N G W A T E R R E V O L V I N G F U N D
