Wastewater rates are based on water usage during any given month. The water Department reads water meters starting on the 27th of each month. The bill will be received by the 1st of the following month with a due date of the 10th before a late fee of 10% is applied.
Shut off date is usually on the 16th of each month for non-payment of the bill.
Mountain Grove residents enjoy lower than normal wastewater rates compared to others in our area. We do this by maintaining all equipment in the best condition possible and keeping current with all regulatory rules. WE are doing a rate study currently and developing a Capital Improvement Plan so that we can insure for generations to come that we have the capability to handle all current wastewater and a plan for growth.
Our Current Rate Structure is:
$6.00 – Minimum Charge
$2.01 – Per 1,000 gallons of water used
