FLOODS AT THE MANCHESTER WATEB WOnKS, ETC. 



their capacity is equal to 32,400 cubic feet for every acre of 

 collecting ground. 



No damage of any consequence was sustained by any 

 portion of the works from the effect of the floods. Their 

 efficiency was well tested and satisfactorily proved ; but the 

 heavy rain penetrating into some ancient land slips on the 

 north side of the valley near the Rhodes Wood embankment, 

 but above its level, set a mass of about 40 acres in extent in 

 motion, which disturbed a quantity of masonry and otherwise 

 deranged the scheme at the spot at which it occurred. The 

 security of the reservoir is not affected; but it will be a 

 work of time and skill to arrest or obviate the effects of this 

 sliding mass.
