(b) any public sewer vested in the undertaker may, upon such terms as may be agreed, be used by the authority for conveying surface water from roads repairable by the authority.

(2) Where a sewer or drain with respect to which a relevant authority and a sewerage undertaker propose to make an agreement under this section discharges, whether directly or indirectly, into the sewers or sewage disposal works of another sewerage undertaker, the agreement shall not be made without the consent of that other undertaker.

(3) Subject to subsection (4) below, a consent given by a sewerage undertaker for the purposes of subsection (2) above may be given on such terms as that undertaker thinks fit.
