Memorandum
This memorandum and resolution requests approval to award a construction contract to Monroe Plumbing and Heating Company for the Sodium Hypochlorite Storage Tank Replacement ($640,980.00).
The City of Ann Arbor (City) Water Treatment Plant (WTP) uses combined chlorine, of mixture of sodium hypochlorite and ammonia, for the purpose of maintaining a disinfectant residual throughout the water distribution system.
