Section 189(1) in The City of Nagpur Corporation Act, 1948
(1)If, in the opinion of the Commissioner any part of a group or block of premises is situated conveniently near a municipal drain already existing or about to be constructed or a place set apart by the [Commissioner] [This word was substituted for the words 'Chief Executive Officer' by Bombay 79 of 1958, Section 3, Schedule.] for the discharge of drainage, and if the [Commissioner] [This word was substituted for the words 'Chief Executive Officer' by Bombay 79 of 1958, Section 3, Schedule.] is of opinion that such group or block can be drained more economically or advantageously in common than separately, he may give the owners of all the premises a reasonable opportunity of stating any objection, and, if no objection is raised or if any objection which is raised appears to him invalid or insufficient, may cause such group or block to be drained by such method as appears to him to be most suitable therefor, and the expenses incurred by him in so doing shall be paid by the owners of such premises in such proportions as the [Standing Committee] [These words were substituted for the words 'Member-in-charge' by Maharashtra 26 of 1999, Section 56.] may think fit.
