Conn. Gen. Stat. § 8-197: Furnishing of municipal services to other municipalities.

Any municipality by vote of its legislative body may for consideration furnish municipal services to, or have municipal services furnished to it by, one or more other municipalities. The consideration for such services may be based, in whole or in part, upon a formula which takes into account the taxes levied on so much of the real property situated in the municipality to which such services are to be furnished as, in the judgment of the legislative body thereof, will be appreciably benefited by such services.
