The Town's irrigation system is a separate non-potable system, with separate valves and mains than the Town's freshwater system.  The irrigation season is from May 1st to October 1st of each year.  The Town budget-bills monthly year-round, however. Odd numbered addresses may use irrigation water on Sunday, Tuesday and Thursday.  Even numbered addresses may use on Saturday, Monday and Wednesday.  Only the Town of Silt can use irrigation water on Friday, for Town facilities, parks and/or open space, and to help fill the irrigation tanks for the weekend. Stoney Ridge Planned Unit Development is not on the Town's system, and therefore is not subject to the Town's watering restrictions. No cross-connection of potable to a sprinkler system is allowed without special permission by the Town and an annual inspection.  Cross-connection of a potable water source to a sprinkler system can result in contamination of the Town's entire water system and can make people ill.
