The effect of the new works has been to increase the gathering-ground by 54 per cent., the Reservoir accommodation by 36 per cent., and the effective water- supply by 26 per cent., whilst the population of the City and Hill Districts has increased by about 17 per cent.
The following statement shows the increase of storage and gathering-ground which has been made since 1892:-
