This is water of a very high degree of purity as regards
freedom from contamination. This is indicated by the results
of a vigorous bacteriological examination as well as by those
of the chemical analysis.
DISPOSAL OF HOUSE REFUSE.
The House Refuse is collected weekly by the Council's
own staff, and conveyed to the Farm. The provision of a

SEWERAGE AND DRAINAGE.
