In the course of the discussion which took place after the 
reading of the above papers several of the members stated 
that the town’s water as received at their houses was some- 
times very turbid, and the President said it ought never to 
be used for drinking purposes without being filtered. 
J. G. Lynde, M. Inst. C.E., F.G.S., said that at his house 
he had always found the water quite clear and pure, and 
that although he had a filter it was now never used. 
T. H. G. Berrey, Ass. Inst. O.E., superintendent of 
the Manchester Corporation Water W T orks, stated, in reply, 
that there was no reason why the water should be dis- 
coloured at the points named, except that it must have 
been caused by the neglect of the turncock to cleanse the 
hydrants according to instructions. The general supply 
throughout the 86 townships supplied by the Manchester 
Corporation was quite satisfactory, and the water was 
never rendered turbid except in the case of a very heavy 
thunderstorm, when the turbid water would sometimes, 
during the night, get into the service reservoirs from the 
adjoining brooks before it could be sent down the flood 
watercourse.
