The Orange Water and Sewer Authority's public hearing tonight will be the last opportunity for public input on a new water conservation ordinance before it is sent to county and town governments for approval.
OWASA Planning Director Ed Holland said the revised ordinance includes better ways of determining when water is in short supply as well as stricter conservation guidelines year-round to ease the effect of drier seasons.
Holland said the new system for measuring water supply will give OWASA a more accurate trigger to alert the community to a shortage.
"The trigger in the existing ordinance is based on days of remaining storage left in reservoirs," he said. "We found this summer that this was not a particularly responsive way to determine a shortage."
The new ordinance will incorporate a system that takes into account time of year and stream flow.
"OWASA's staff and board would be able to make a better determination of when to go to other (restriction) levels."
Holland said the stricter water-usage restrictions will help the community stave off a shortage and cope with any shortage that does occur.
Citizens would be limited to watering their lawns three days per week year-round and prohibited from watering during the day, when more water is lost due to evaporation.
During stage one water restrictions, only one day of watering will be allowed, Holland said.
