Regarding the Aug. 21 letter by Bruce Gibson, “Water district not exactly conserving,” he wrote that he observed Crescenta Valley Water District servicemen flushing the water main at a fire hydrant near his home.
Your first thought may be that we are ignoring our own philosophy of conserving water. However, it is necessary to flush water mains in the system, particularly ones that are not “looped” or connected in such a way that water continually flows through these pipes.
Although it may appear to waste water, fire hydrants flushing is a routine preventive maintenance program required to remove sediments that may have accumulated inside the distribution system.
