 Cliff’s
Corner
By:
the President of Wachs Utility Services, Cliff Wilson
Hydrant
Unidirectional Flushing is a great idea with measurable benefits;
And yet most utilities that have attempted to execute Unidirectional
Flushing, have failed, usually abandoning the program very
early on. Why Unidirectional Flushing programs fail is the
same reason water systems across the country are failing: lack
of operability.
Using 40% less water while achieving real scouring velocities
makes Unidirectional Flushing irresistible, especially to utilities
suffering from poor water quality or from water shortages.
In today’s quarterly newsletter we hope you’ll
find some relevant information on Unidirectional Flushing.
Yours in Service,

Unidirectional Flushing Optimizes Distribution
Systems
It's midnight in our nation's capital. The faces
on the walls in the National Portrait Gallery stare into the
dark. The crush of tourists is long gone from the city's sidewalks.
But at this midnight hour, underneath the sidewalks and streets,
water mains hum at high velocity as the DC Water and Sewer Authority
(DC WASA) and Wachs Utility Services crews execute this progressive
water agency's hydrant unidirectional flushing program.

GPS Mapping
As water
utilities go digital with information, GPS Mapping of water
assets is proving to be essential to increased efficiency and
productivity. Wachs' unique approach is to combine GPS mapping
with asset rehabilitation services. When executing field services,
such as valve exercising or hydrant flow testing, highly trained
technicians capture sub meter GPS coordinates and up to 50
attributes per asset using drop-down menus and GPS capture
restrictions. Wachs data analysts then postprocess the data
to ensure its accuracy and prepare the data for integration
into the municipality’s
GIS. |
