Health (Fluoridation) Act 1973

Before adding fluoride to any public water supply under its control, a water supply authority shall—

submit to the Secretary plans and specifications for the proposed scheme for fluoridation;

specify the public water supply and the district or districts in respect of which such scheme is intended to operate; and

furnish to the Secretary such further information as the Secretary may in any case require.

After considering the proposed scheme in relation to the aspects of public health and the ability of the water supply authority to operate the scheme satisfactorily, the Secretary shall—

determine the maximum concentration of fluoride expressed as parts of fluoride ion per million parts of water by weight that may be established in the public water supply by the water supply authority;

specify the compound or compounds of fluoride that may be added to the public water supply concerned; and

advise the water supply authority of its decision in these matters.

The water supply authority adding fluoride to a public water supply—

shall so regulate the concentration of fluoride that such concentration shall not exceed the maximum concentration determined by the Secretary; and

shall not add to the public water supply fluoride in any form other than that specified by the Secretary.

Where a water supply authority was, immediately before the commencement of this Act, using any equipment for the purpose of adding fluoride to any public water supply under its control such water supply authority shall forthwith submit plans and specifications of its scheme to the Secretary for consideration as required by section 6.

Notwithstanding anything in sections 5 or 6 such authority may subject to the other provisions of this Act and the regulations continue the use of such equipment.
