Where a unit of local government or the community public water supply does not require separate water service lines for irrigation or similar systems that are likely to impose continuous demands (e.g., lawn sprinkler or air conditioning systems), the following rule applies: estimate the continuous demand (in gallons per minute) for outlets/systems separately from the intermittent demand from the fixtures listed in this table, and add this amount to the demand of the fixtures (in gallons per minute). Fire sprinkler systems are exempt from this table.
