Unidirectional Flushing Programs

Development, Implementation, and Updates to Unidirectional Flushing (UDF) Programs

Weston & Sampson has been working closely with Providence Water in creating custom flushing sequences to develop a system-wide UDF program. Implementation of flushing sequences has helped lower iron and turbidity levels system wide. Implementation of the UDF program included assistance with organizing union forces, development of standard operating procedures for flushing practices, development of customized Apple iPad (iDataCollect) forms, and field training. Through the UDF program, Providence Water continues to lower iron and turbidity levels, while increasing the chlorine residual and improving the water quality throughout the distribution system.

The Boston Water and Sewer Commission selected Weston & Sampson  to update its existing unidirectional flushing (UDF) program sequences and conduct the flushing. The updated UDF program’s objective was to improve the flushing sequences by reducing the number of valve closures required. This task was completed with the goal of achieving effective and efficient UDF program implementation.

We have assisted many municipal water systems with their UDF programs.
