The Bethel Planning and Zoning Commission has approved a water tank Long Meadow Lane and Briar Cliff Manor. The tank located in the woods of a residential area would be able to hold 500,000 gallons. The approximately $1.8 million project is expected to be paid for with a state Department of Public Health loan, paid back by water customers. The tank would provide water in the Chestnut Ridge area on peak days and during emergencies, such as a fire or water main break. Some state and local approvals are still needed.
