They might also consider pricing
Globe West recently highlighted the issue that day-of-the-week restrictions on watering lawns may actually lead to increased watering. The restriction can serve as a reminder to water on a regular basis. The article notes that the state may consider stricter restrictions. Perhaps the state and municipalities should also consider using pricing as a policy tool to achieve conservation. I would direct them to Pioneer’s recent paper on the topic by Professors Rob Stavins and Sheila Olmstead at this link.
