City of Parksville crews will begin the annual winterization of irrigation systems located in the city’s parks and along roadway streetscapes on Oct. 24.
“Winterization is an important maintenance procedure to help ensure the longevity of the city’s irrigation infrastructure,” reads a news release from the city.
The city has approximately 90 irrigation systems, with up to 35 zones per system and the winterization process is expected to take about four weeks, the release said.
Irrigation winterization involves the use of large compressors which force air through the system to remove any residual water, so it will not freeze within the underground pipes.
When the city moved to Stage 4 watering restrictions on Oct. 4, in line with the provincial drought level, it turned off all water supply to its irrigation system, according to the release.
The only water being expelled during the during the winterization process is water already in the irrigation lines and heads.
“We can no longer wait to complete irrigation winterization, now critical before temperatures fall below freezing,” the release read.
When the city winterizes its irrigation system, it shuts off water at the point of connection and a compressor is attached to the irrigation system. Compressed air is run through each zone until the water no longer streams out of the irrigation heads and becomes a fine mist. The compressor is then shut off and moved to the next system.
The city also reminded homeowners with lawn sprinkler and irrigation systems connected to the city’s water and sewer system that it is time to winterize home irrigation systems as well.
Home irrigation systems, including garden hoses, should be cleared by shutting off the water, deactivating the system and draining remaining water to prevent damage from water freezing in the lines, according to the release.
