Storm sewers are identified as the large grates in streets and near curbs. This is a common question we hear. The city adds chemicals to the water for many reasons, first to help soften the water, and second, to provide a safe and helpful water. Third, the chemicals help protect the homeowner and mains. Lime and soda ash are added to help soften the water.
Chlorine is added for destruction of harmful bacteria in the water.
Fluoride is required by the state to promote sound teeth with high resistance to decay. Fluoridation is only a supplement to the natural fluoride already found in the water. Phosphate is added to help keep minerals in suspension, so they won't drop out and cause deposit on the mains and in your pipes at home. The choice to buy a home softner is a personal choice. The water plant produces a balanced water that is moderate hard.
