Royal Commission on Sewage Disposal
The Royal Commission on Sewage Disposal was established by the British government in 1898 to report on: (1) What method or methods of treating and disposing of sewage (including any liquid from any factory, or manufacturing process) may properly be adopted,consistently with due regard for the requirements of the existing law, for the protection of the public health, and for the economical and efficient discharge of the duties of local, authorities; and (2) If more than one method may be so adopted, by what rules, in relation to the nature or volume of sewage, or the population to be served, or other varying circumstances or requirements, should the particular method of treatment and disposal to be adopted be determined The commission convened and re-convened eight times under three different reigns, Victoria, Edward VII and King George V, and remained active until 1912 and in that period published nine reports.
