1. CONTRACTOR SHALL HAVE A SUMP PUMP AND A MINIMUM OF 100' OF APPROPRIATELY SIZED HOSE WITH FLOW
DISSIPATER FOR DEWATERING LIFT STATION FOUNDATION.

REDUCE THE POTENTIAL FOR EROSION AT THE DISCHARGE LOCATION. THE PERIMETER OF THE DISCHARGE PROPERTY
SHALL BE MONITORED FOR SURFACE WATER RUNOFF DURING DEWATERING OF THE FOUNDATION. SURFACE WATER RUNOFF
FROM THE PROPERTY IS ACCEPTABLE IF IT IS MEASURED AT LESS THAN 10ONTU TURBIDITY AND IS NOT CAUSING
EROSION.
