Power to stop water supply

The supply of water to any water-course or to any person who is entitled to such supply not be stopped except— (a) whenever and so long as it is necessary to stop such supply for the purpose of executing any work ordered by the competent authority competent to accord administrative approval under the C.P.W.D. Manual. (b) whenever and so long as any water-course by which such supply is received is not maintained in such repair as to prevent the wasteful escape of water therefrom; (c) whenever and so long as it is necessary to do so in order to supply in rotation the legitimate demands of other persons entitled to water; (d) whenever and so long as it may be necessary to do so in order to prevent the wastage or misuse of water; (e) within the periods fixed from time to time by a Canal-Officer duly empowered by the Government in this behalf, of which due notice shall be given; (f) whenever there is diminution in the supply of water in the canal work due to any natural or seasonal causes and so long as it is necessary to do so. If a portion of any land for the irrigation of which supply of canal water has been sanctioned is irrigated by well water for a part of the season owing to a deficiency in the supply of canal water and the applicant notifies the fact in writing to the Canal-Officer within eight days from the date on which he began taking well water, enquiry shall be made by the Canal-Officer as to whether the use of well water was necessary and if it be shown to the satisfaction of the Canal-Officer that the use of well water was necessary the rate chargeable on the portion irrigated by well water may, at the discretion of the Canal-Officer, be reduced to an amount which shall not be less than half the rate otherwise payable.
