When you enter the
subterranean maze of the water distribution and sewer collection systems,
you are dealing with a hidden system of pipes and tiles that carry finished
water to the customer and used water away. This system
intertwines with other underground utility systems -- electric, gas,
telephone, cable TV and fiber optic cables.
A few parts of the system are
visible. Water towers and fire hydrants are easily noticed. Manhole lids
and water valves are there for those that pay attention, but, most of the
system is buried.
If your grandfather or
great-grandfather installed water or sewer lines, he may have installed some
of Galion's lines. Many of our water lines are 50 to 60 years old. Many
of our sewer lines are older.
Combining the water system and the
storm and sanitary sewer system, the 12 man maintenance crew maintains more
than 250 miles of underground pipes -- about 1,320,000 feet of pipe. If you
add 2600 catch basins (each one is cleaned each year), 500 plus fire
hydrants (each of which is flushed each year) and another 500 manholes,
drinking fountains in the parks, 500 plus utility locates a year, assisting
with the swimming pool operation and reservoir maintenance, and the almost
700 logged work orders a year generated by customer requests or complaints,
these guys are busy.
Our maintenance crews replace small, old lines on an annual basis. Most of
these replacements are driven by complaints received by the customers.
When prioritizing line replacements we look at customer complaints but also
consider the benefit to the system as a whole. If there is a fire flow
benefit or an increase in circulation throughout a portion of the
distribution system, that replacement receives a higher priority.
Our
line replacement dollars are few and our crew's time very valuable -- we do
what we can schedule and what we can afford.
On the sanitary sewer
side, our main concerns are system backups and inflow.
Perhaps our biggest challenge is the removal of inflow to our system.
Inflow is the
introduction of clean water to the sanitary sewer system through a direct
connection. Most often these connection are footer tiles that either
directly connect to the sanitary, or are pumped to the sanitary.
