"I don't feel we'll be up there repairing the leaks at the top of that hill (for a while)," Grand Haven Public Works Director Bill Hunter said Monday.
City Council on Monday night approved a water main replacement project for Water Tank Hill at a cost of $763,790.
"We got two bids in, and the great thing was the low bid was below the engineers' estimate by $20,000," Hunter said.
The project is part of the city's recent slate of $5 million capital improvement bond issue projects. Half of the funding is coming from the city's general fund and the other half is slated to come from bond issue funding.
The work will come just over a year after a line break caused a side of the hill to wash away, and the city was forced into an emergency repair to fix the water lines and shore up the hillside.
"The project in and of itself is simply replacing all of that old, antiquated piping on the top of that hill," Hunter said.
According to city officials, the project’s scope includes:
• Drilling 20-inch pipe down the side of the hill toward Elizabeth Street, tying into the existing 16-inch cast iron line.
• Drilling 12-inch pipe down the side of the hill toward Lake Avenue, tying into the existing 4-inch cast iron line.
• Replacing pipe within the fenced-in tank area.
• Installing new mixers in the 2-million gallon and half-million gallon tanks atop the hill.
Hunter noted that the new mixers will improve the quality of the drinking water.
"I believe that when that system gets installed, it will help us with (the EPA’s) Stage 2 disinfectant byproduct thresholds," he said.
