The first full‐size three‐stage water treatment works was built at Blackmoorfoot (near Huddersfield) just over six years ago. The three‐stage treatment process involves flotation, first‐stage filtration and subsequent manganese removal in three distinct stages. The works at Blackmoorfoot has been followed by several others in Yorkshire Water. This paper (a) describes the three‐stage treatment process and its developments, (b) relates the operating experiences of the new works to date, and (c) gives some of the operating costs. The treatment process has been successful in treating upland Pennine waters and, as a result, water quality throughout the area has improved. The paper also shows that the process can be modified where water quality allows. The operating costs of the new process are affected by the economies of scale, but need not be greater than those of the older works which have been replaced.
