Plant History

Water production for the City has been in its present location since 1905. Treatment in 1905 only amounted to pumping water directly from the lake to the city while only adding a small amount of chlorine. Pumping was done by using steam-driven pumps, There were no elevated storage tanks. Since that time additions to the treatment plant have expanded not only the capacity but also the quality of the water produced.           

Additions to the treatment:

·     In 1922 a filtration plant was added with a capacity of 3 million gallons per day. Pumping was still accomplished with steam-driven pumps. With this expansion, the tap water was now being filtered for the first time.

·     1935 brought increased finished water storage. Expansion increased the storage from 500,000 gallons to 1 million gallons.

·     In 1953 steam pumping became a part of the past. An electrified high-service pumping station was added to the plant and the steam pumping station was shut down, soon
to be demolished. At this time the Ninth Avenue elevated storage tank was constructed. This tower has a capacity of 750,000 gallons.

 ·     1965 a filter plant expansion was completed, and this increased plant production from 3 million gallons per day to 5.25 million gallons per day. Three filter bays were added bringing the total filters to seven. 

·     1999 treatment changes brought about construction of
a combination building. This building houses bulk storage of bleach, carbon feed, distribution storage and a new back-up generator. 

At present the plant capacity is six million gallons per day. Plans to increase capacity to eight million gallons per day
are in the near future.

Treatment

The water plant is a conventional surface water plant. That means that we use coagulation, flocculation, and filtration to clean our water. Once the water enters the treatment, it will take 12 hours to complete the treatment cycle. Along the way at least 50,000 samples are collected and analyzed per year and fluoride, phosphate, and flocculant aides are added.

Average Daily Production

Over the year, the average daily production is 2.3 million gallons per day.  On a hot, dry, summer day we can produce 5 million gallons a day to meet the City and Township water needs. Our lowest production usually occurs on Christmas day with approximately 1.8 million gallons produced.

Water Source

Thunder Bay, Lake Huron is our source of water. The intake line is 40-inch diameter pipe with a 30-inch polyethylene liner and two rock and timber intake structures at 1,000 feet and 2,000 feet. The rated capacity of the intake pipe is 8 million gallons per day at 2.52ft/sec. Control of zebra mussel colonization within the intake pipe is accomplished via chemical addition.

Low Service Pump Station

Four low-service pumps deliver lake water from a shore well structure to the treatment plant. Total low-service capacity is 13.5 million gallons per day.

Laboratory

Our laboratory is certified by the State of Michigan to test for Total and Fecal Coliform bacteria. These are the primary indicator organisms for water quality, both for drinking and swimming/recreation. We also test for chlorine (disinfectant), pH, hardness, alkalinity, turbidity, and fluoride. The State Drinking Water Laboratory tests our water samples for other possible contaminants as required.

Auxiliary Power

One 750 KVA diesel powered (1034 HP) generator is available to operate the entire water treatment plant. This generator will produce all of the necessary electricity to meet City needs during any power failure. The auxiliary generator is exercised quarterly.
