DARIEN — Town residents are not adhering to Aquarion Water Company’s two-day a week irrigation policy, according to a weekly report issued by Aquarion.

In Monday’s report from Aquarion, the company’s patrols found 374 first-time violators in Darien. Of those, 39 received a second notice of violation, according to First Selectman Jayme Stevenson.

“It’s a significant number of customers who are violating the policy,” said Stevenson at a recent meeting of the Board of Selectmen.

According to rules set by Aquarion to conserve water, there is a twice-weekly sprinkler policy that applies to Darien, New Canaan, Stamford and Greenwich based on the last digit of each resident’s address number.

Addresses ending in even numbers, or those without a numbered address, may use sprinklers Sundays and Wednesdays before 10 a.m. or after 6 p.m. Addresses ending in odd numbers may water their lawns Saturdays and Tuesdays before 10 a.m. or after 6 p.m.

Sprinkler use is actively monitored by Aquarion to ensure compliance.

“If you get to three they actually have the regulatory authority to turn off your water. I will fight against that as First Selectman. Having water is a primary necessity for life,” Stevenson said.

Aquarion’s Director of Public Relations Peter Fazekas said on Tuesday that since the twice-weekly policy was instituted in May, no third warnings have

been issued.

“It’s always been resolved at that second violation point. Either the customer needs to contact their irrigation contractor or they need to apply for a variance,” Fazekas said.

There are two types of variances, both available online, that can be applied for to allow for increased watering: a new planting variance and a large property variance.

“If someone is either reseeding their lawn, planting new shrubs, they can go to their website and apply for a five week variance that allows them to water outside the two days a week to ensure that the new plantings survive,” Fazekas said.

He added that all four communities have been very supportive of the conservation policy, although Darien has had the highest number of offenders.

“It was very surprising to me that Darien’s violations were the highest among the four communities,” Stevenson said.
