Manganese in Drinking Water – Budgeting for Treatment

Many water suppliers in New England have one or more wells with high manganese levels that create a lot of operational and customer problems. However, it can be hard to get approval for treatment where it isn’t mandated and is not considered a health threat. Recent studies have suggested a health risk in children that was previously unrecognized and this is pushing some water suppliers to consider manganese treatment more seriously.

If you are thinking about constructing a treatment facility to remove manganese, the biggest question on your mind may be “How much will it cost?” The total cost will depend on many factors including:

  • Volume and flow rate of water to be treated
  • Amount of manganese in the source water
  • Type of treatment selected
  • Treatment complexities introduced by other contaminants in the water and treatment goals
  • Operational considerations
  • Style of building selected to house the new equipment
  • Borrowing interest rates

 

There is no set cost per gallon for manganese treatment. A small facility will generally cost more per gallon than a larger facility with the same type of equipment. A very small system, such as a school, may be able to implement treatment in the tens or hundreds of thousands of dollars range. However, the cost for most municipal systems to implement manganese treatment may exceed $1 million depending on many factors.  Keep in mind the cost to implement treatment should be balanced against any savings in sequestering chemicals, reduction in customer complaints and benefits to public health and customer satisfaction.
