The big winner in the bidding war for two water-related projects in American Fork is the city.

Thanks to low-bidding construction and supply firms, American Fork will spend about $395,000 less than expected on construction of a new 5-million-gallon water tank, waterlines and other improvements to the system.Hadco Construction of Lehi was the low bidder on construction of the water tank. Hadco bid $720,027.11, well below the city's estimated cost of $925,000. Hadco also came in low on the waterline projects, bidding $422,646.10. A city engineer had estimated the project would cost $600,000.

Hadco's bid on the waterlines was $105,000 less than the second lowest bid.

W.R. White of Salt Lake City won the supply contract for the projects, bidding $318,034.90. The city estimate was $330,000.

The projects will take 180 days to complete. American Fork residents approved rate hikes last November to pay for the projects. The base water rate increased $2, from $6 to $8. The usage rate, charged for water use over 1,000 gallons, increased 15 cents.
