Subject to sections 130 and 133 below, a sewerage undertaker may enter into and carry into effect—
an agreement with the owner or occupier of any trade premises within its area for the reception and disposal by the undertaker of any trade effluent produced on those premises;
an agreement with the owner or occupier of any such premises under which it undertakes, on such terms as may be specified in the agreement, to remove and dispose of substances produced in the course of treating any trade effluent on or in connection with those premises.
Without prejudice to the generality of subsection (1) above, an agreement such as is mentioned in paragraph (a) of that subsection may, in particular, provide—
for the construction or extension by the sewerage undertaker of such works as may be required for the reception or disposal of the trade effluent; and
for the repayment by the owner or occupier, as the case may be, of the whole or part of the expenses incurred by the undertaker in carrying out its obligations under the agreement.
It is hereby declared that the power of a sewerage undertaker to enter into an agreement under this section includes a power, by that agreement, to authorise such a discharge as apart from the agreement would require a consent under this Chapter.
