Power to examine and test sewers, etc., believed to be defective

(1) Where it appears to the Commissioner that there are reasonable grounds for believing that a private sewer or cesspool is in such condition as to be prejudicial to health or to be a nuisance or that a private sewer communicating directly or indirectly with a corporation sewer is so defective as to admit sub-soil water, he may examine its condition and for that purpose may apply any test, other than a test by water under pressure, and if he deems it necessary, open the ground.

1. (2) If, on examination, the sewer or cesspool is found to be in proper

condition, the Commissioner shall, as soon as possible, reinstate any ground which has been opened by him and make good the damage done by him.
