If the drainage systems of a private building are found to be defective, inadequate or insanitary, Building Authority may serve an order under section 28 of the Buildings Ordinance (Cap.123) requiring the owners to carry out investigation and/or repairs within a certain period of time. Only in an emergency or in owner's default of an Order, Buildings Department would carry out works on his behalf and recover the cost of the works, plus supervision charge and surcharge from him. Some examples with completion of repair works are shown below.
