Power to examine and test sewer etc. believed to be defective

(1) where it appears to the Departrnent that there are reasonable grounds for believing that a private sewer or cess-pool is in such condition to be prejudicial to public health or to be a nuisance or that the private sewer communicating directly or indirectly with a Government sewer main is so defective as to admit sub-soil water or grit or other materials, the Department may examine its condition and for that purpose may apply any test, and if it deems it necessary, open the ground. (2) If on examination the sewer or cess pool is found to be in proper condition, the Department shall, as soon as possible, reinstate any ground which has been opened by it and determine and pay compensation for the damage caused by it.
