Section 53

If it appears to the Director‑General that any sanitary conveniences provided for or in connection with a building or part of the building are in such a state as to be defective or prejudicial to health or a nuisance, but that they can without reconstruction be put into a satisfactory condition, the Director‑General must, by written notice, require the owner or occupier of the building to execute such works or to take such steps by cleansing the sanitary conveniences or otherwise as may be necessary for that purpose.
