| The City of
Grand Junction, Persigo WWTP collection crew's are responsible
for cleaning and maintaining the City's portion of the collection
system. This consists of 346 miles of sewer line, 32 lift stations,
numerous catch basins and manholes . They are on-call 24 hours
a day, 365 days a year, to respond to any emergency that should
arise in the City's or if needed, the Sanitation District's
systems. |
| The 32 lift
stations contain 64 pumps, totaling 602 horsepower, with a combined
pumping capacity of 11.5 million gallons a day. |
Lift Station
Service Truck |
Two high-pressure jetting
trucks and one combination jetter/vactor truck , each with
a crew of two, clean the City's entire sanitary sewer system
approximately once every 2.5 years. This does not include
the additional cleaning of storm or irrigation pipelines.
You might see the City’s
sewer jetting trucks hooking-up to fire hydrants to replenish
their water storage tanks. The City’s trucks are identifiable
by the City logo and unit number on the side. The water is
used to high pressure spray (jet) the inside of the sewer
lines to clean and break-up any debris. This is perfectly
normal and safe. Only potable water is stored in the
tanks and all the trucks have a back-flow prevention device.
This will stop any water in the tanks from being pulled back
into the water system.
An added benefit is this will exercise the fire hydrants and
make sure they work during an emergency.
