|Why does Lacey need to clean the water lines? |
Over time, minerals from our deep well water can accumulate
inside water pipes. While these minerals are generally harmless, changes in
flow can sometimes result in cloudy, discolored water. In order to maintain
high water quality, these materials need to be removed regularly.
How are the water lines cleaned?
Lacey field crews open fire hydrants and blow-off valves to flow large amounts of water in a planned route. The water travels so fast that it is strong enough to remove the build-up of minerals from inside the pipes. We refer to this activity as "flushing”.
|What should I expect to see when Lacey performs waterline flushing? |
You may notice a slight discoloration of your water when
flushing takes place. This is temporary and is not harmful to your health. If
you experience coloring or sediment in your water, let your tap flow for a
short time (5-20 minutes) until it runs clear before using it for drinking,
cooking, or clothes washing.
When flushing does occur, you may see water flowing along
the gutter line of the street and entering storm drains. At times, this water
may be very cloudy or brownish in color.
Signs are posted before flushing takes place in a
neighborhood and in the immediate area where Lacey crews will be working.
|When does waterline flushing take place? |
Flushing activities begin each fall and continue until late
spring (October through May). Because waterline cleaning uses large amounts of
water, flushing does not take place in the summer when customer demand for
water is at its highest.
It takes nearly five years to complete one cleaning cycle of
the entire city’s water distribution lines. Some parts of the water system
require flushing more frequently and may need cleaning every year. Water
quality sampling throughout the distribution system, helps staff determine
which parts of the system need greater attention.
