Proyecto de ingeniería SGWASA
Unidirectional Flushing (UDF) Program
Presupuesto:
$45,000
Hito actual:
SGWASA
SGWASA's Board of Directors recently approved the unidirectional flushing pilot task order for Hazen &
Sawyer, totaling $45,000.00.
A pilot program has been designed to enhance water quality and reliability by reducing stagnation and removing material that can contribute to discoloration complaints and other water-quality concerns. This program will support compliance and operational performance by formalizing a strategic maintenance approach that can be repeated and expanded system-wide.

As SGWASA continues to upgrade and improve its water system, a dedicated flushing program is
needed to improve water quality throughout our service area. The task order that Hazen has provided
is a pilot test for a unidirectional flushing program that focuses in the Golden Pond subdivision, which
has approximately 5.3 miles of distribution mains (water lines).
This task order from Hazen includes updates to the water model, development of a unidirectional
flushing program in this subdivision, 5 days of field support for SGWASA, project administration with
meetings between Hazen and SGWASA, as well as 2 board presentations (one prior to starting this
pilot and one after).
As SGWASA continues to upgrade and improve its water system, a dedicated hydrant flushing
program is needed to enhance water quality across the service area. The task order submitted by Hazen
& Sawyer proposes a pilot unidirectional flushing program focused on the Golden Pond subdivision,
which includes approximately 5.3 miles of water distribution mains.
This project includes updates to the water system model, development of a unidirectional
flushing plan for the subdivision, five days of on-site field support for SGWASA staff, project
administration and coordination meetings, and two Board presentations.
SGWASA staff will make direct use of the newly purchased valve exercise machine for this flushing
program and will turn every valve in this subdivision, as well as flush every hydrant.

Unlike routine flushing, which generally supports day-to-day water freshness, UDF is a controlled, high-velocity flushing method that isolates pipe segments through deliberate valve operations to scour mains. This process is also beneficial in removing accumulated material, like sediment and corrosion byproducts, supporting long-term asset stewardship.
