A. 
A regrettable and vexatious situation has been brought about by the deliberate introduction of stormwater flows into the Town sanitary sewer system, local sewers and thence into the county system causing the serious overloading of otherwise adequate sanitary sewers. The county publicly owned treatment works are plagued with extreme wet weather flows which unduly handicap the efficiency of plant operation, increase operating costs and necessitate the enlargement of treatment facilities.
B. 
It is one explicit purpose of this chapter by the application and enforcement thereof to deter, prevent and eliminate, as far as possible, the introduction of stormwaters into the Town sanitary sewer system and all public sewers tributary thereto. However, it is recognized that in certain areas the immediate and strict application and enforcement of this chapter against existing and established connections would be infeasible and unreasonable.
C. 
This section shall not be construed to mitigate in any way the application and enforcement of this chapter against the construction of any new combined sewers and against any new connections discharging stormwater to the Town trunk sewer system and public sewers tributary thereto or to the alleviation of unreasonable flows of stormwater nor shall this statement of policy be construed to be used as a defense against any changes which may be ordered by state or federal regulatory agencies.
A. 
No stormwater connection from any building or yard nor any drain from any catch basin, lake, swamp, pond nor any inlet for surface water, stormwater or groundwater of any kind shall be connected to the Town trunk sewer system or any public sewer tributary thereto or to any private sewer connected to any such public sewer. Existing facilities mentioned above which are presently connected directly or indirectly must be corrected.
B. 
Within any area served by a separate sanitary sewer system, no stormwater shall be allowed to enter soil, waste or vent pipes from any building. Within any such area, no down spout or leader, gutter or other pipe, drain or channel which may at any time carry stormwater surface drainage derived from hydraulic pressure or from well points, cooling water or seawater shall be connected with any sanitary sewer. Every joint in the connection to a sanitary sewer shall be made watertight so that no leakage into or from such connection shall occur.
C. 
Subject to the approval of the Superintendent, the provisions, stipulations, requirements and enforcement set forth in Subsections A and B above shall, however, be subject in the first instance to the applicable provisions, stipulations and requirements of any existing or amended rules, regulations, codes or ordinances adopted by a municipality or sewer district having jurisdiction over public sewers tributary to the Town trunk sewer system. Wherever there is a conflict between this chapter and the existing rules and regulations of a governmental authority having jurisdiction, the more stringent rule or regulation shall prevail.
