(1) No site which shall admit storm-water draining into it owing to its level or location shall be used for the construction of a building, unless arrangements are made to prevent effectually the flooding of the site either by draining into a storm-water course, if such a course is available, or by raising the level of the site to an adequate height by the deposit of layers of sand and non putrescible materials.
(2) No site wherein the soil and sub-soil shall be so saturated with water that dampness of the floor and walls of the building is inevitable, shall be used for the construction of a building, unless a damp-proof course is provided in the basement of the building not higher than the level of the lowest floor and unless the flooring is made with a material approved by the Licensing Authority which shall effectively prevent the dampness rising in the floor of the building.
(3) Every person who constructs, reconstructs or alters or adds to, a building shall, wherever the site is within fifteen meters of any tank, reservoir, water-course, river, fresh-water channel or well, carry out such measures as may be necessary or as the Licensing Authority may direct, for the purpose of preventing any contamination of, or any risk of the drainage of the building passing into, such tank, reservoir, water course, river, fresh water, channel or well.
