A custom bulk dewatering system for 100% compliance

An advanced integrated solution to control both cost and risk

Challenge
A major North American power utility needed to dewater ash ponds at old sites without permanent power. To ensure compliance with state permits as well as company ash pond procedures, several variables had to be monitored including TSS and PH limits. Water levels could not drop more than 12” a week and had to stop before 3.5’ of remaining water was left in the basin. Before a limit was exceed, alarms needed to be sent out and the system had to be shut down automatically. All of this needed to be monitored continuously during operation and data recorded automatically and retained for record keeping requirements. The system also needed to run for a 12-18 month minimum period in all kinds of weather.
