A series of analyses of samples of the sewage show it tobe comparatively fresh at the point of discharge, the grad-ients being excellent and the distance of flow short. Theaverage strength of the sewage is comparable with the class .*ijj/r/i,r >ra,i Ouf > f;a^ Ot4f/ef.

The city is sewered on the separate system, but aproportion of the rain fall enters the sewers from roofs anda small amount of subsoil water also enters the sewers. There is one main outfall siewer for the whole system,which up to the present has discharged raw sewage into theBelly River about a quarter of a mile below the city intake. The demand for sewage purification is caused by thelarge number of typhoid cases in the mining centres depend-ing upon the river as a source of water supply below thepoint of sewage discharge. as described as weak in the fifth report of the Royal Com-mission on Sewage Disposal (Great Britain.)
