N.Y. General Municipal Law § 120-a: Contracts for sewerage disposal

§ 120-a. Contracts for sewerage disposal. The respective

municipalities and districts may contract with each other, or they may

jointly or severally contract with a third person, corporation or

municipality, either for the construction, operation, maintenance or

leasing of a complete comprehensive system for the removal and disposal

of sewerage, or of a trunk line system with or without lateral

connections, with or without the sewerage disposal plant or of a

sewerage disposal plant; each of the boards or commissioners, however,

binding only the municipalities or districts which they respectively

represent. Such municipalities jointly acting through such board or

commissioners, if they deem it expedient so to do, may contract with any

other municipality or municipalities through or over whose territory

such trunk sewer or sewers are intended to pass, for the construction of

said outlet, trunk sewer or sewers and appurtenances located within the

territory of such other municipality, in such manner as may be agreed

upon between such other municipality, and the municipality theretofore

jointly contracting as herein authorized, or such jointly contracting

municipalities may contract in writing with any other municipality or

municipalities for the privilege of connecting its or their sewers and

drains with such outlet or trunk sewer or sewers so to be jointly

constructed by the municipalities originally contracting for the public

improvements or works hereby authorized, and it shall be lawful for such

other municipality or municipalities to enter into a contract for such

purpose, upon such terms and for such consideration and length of time

as may be mutually agreed upon between all the contracting

municipalities.
