of waste waters from mines. The 10th and final report, published in 1915, summarised the findings of the previous reports and made proposals for the establishment of river boards across England and Wales to complement the three (the West Riding of Yorkshire Rivers Board, the Mersey and Irwell Joint Committee, and the Ribble Joint Committee) already in existence. The findings of the commission were to be used to enact legislation to control sewage and manufacturing pollution of water that continued in force up until the enactment of the Water Act 1974. It was the eighth report of the commission that established the 30:20 standard for sewage effluent that remained the most widely used standard in many parts of the world up till the present.
