The sewers, other than the main sewers, were vested in them, with the contingent duty of maintaining, repairing, and cleansing them, and they were given power to put sewers in every street. Also, they were given power, under certain circumstances, to compel owners of houses, "whether built before or after the commencement of this Act," to construct drains into the common sewer. Furthermore, no house was to be built without drains constructed to the satisfaction of the Vestry, or without sufficient sanitary conveniences, and they were directed to cause open ditches, sewers, and drains of an offensive nature, or likely to be prejudicial to health, to be cleansed, filled up, and covered. And they were required to appoint scavengers to collect the dirt and rubbish, or to contract for its removal. And each of the authorities was to appoint one or more Medical Officers of Health, whose duty it should be to inspect and report periodically upon the sanitary condition of the parish or district, and who would act as medical adviser to the Vestry in all matters relating to the public health, and was also to appoint one or more Inspectors of Nuisances to report as to the existence of nuisances or disease, and perform various other duties in connection with the sanitary condition of the parish. Provision was also made for the prevention of the sale of food unfit for human consumption. The Sanitary Inspector "might at all reasonable times inspect and examine any carcase, meat, poultry, game, flesh, fish, fruit, vegetables, corn, bread, or flour exposed for sale," and in case the same appeared to him to be unfit for such food it might be seized, and the magistrate might order it to be destroyed, and the person to whom it belonged, or in whose custody it was found, should on conviction be liable to a penalty of £10. By "The Nuisances Removal Act for England" the word "nuisances" was so defined as to include any accumulation or deposit which was injurious to health, "any premises in such a state as to be injurious to health, any pool, ditch, water-course, cesspool, drain, or ashpit, &c., so foul as to be a nuisance or injurious to health."
