- Phosphorus, Total; or
- Suspended Solids, Total
Extra Strength Surcharge Agreement fees are reviewed and adjusted accordingly as determined by the Town based on projected operating and maintenance costs. These fees are necessary to ensure recovery of operation and maintenance costs.
Discharge Agreements include conditions for payment for wastewater treatment of potable water that has not been supplied by the Town. Conditions include a valid Permit to Take Water and a written discharge agreement approved by the Town.
