System permit conditions, sludge use and disposal requirements, and
any other federal or state laws to which the sewerage system is subject.

of areas to be served by the Town's sewerage systems and areas
where sewers are to be avoided, sets priorities for the allocation
of sewerage system capacities, and describes the policies and programs
to control surface water and groundwater pollution problems. The plan
was first adopted March 8, 1995, by the WSA and approved by the First
Selectman and may be amended from time to time by these parties.
Maps of the sewer service areas approved by the WSA shall be
filed with the Town Clerk.
A. The Central SSA generally serves the Borough, an area north of Taunton
Pond, and a portion of Sandy Hook.
B. The State SSA serves the state properties in accordance with the
Town and State Intergovernmental Sewerage Agreement dated November
17, 1993.

between the Town of Bethel and the Town of Newtown dated March 6,
1991; and the modification (to Bethel-Newtown Agreement) dated August
11, 1991.

The WSA intends to control surface water and groundwater pollution
problems in these areas by supporting strict administration of on-site
wastewater management policies in cooperation with the Newtown Health
District.
