Peter Hoogendoorn has worked for the City of Langley for more than 15 years. This week, he was tasked with flushing the water mains around the City. He was near Sendall Gardens on March 18, flushing the system, a job that can take an average of 20 to 30 minutes. The water is let run down the streets and into the drains each spring, until much of the sediment built up in the pipes during the winter is cleared out.
