From a consideration of these results, I am of opinion that
the water is imperfectly purified.

Polluted Wells.
Enquiries into a case of Enteric Fever at Top Locks,
aroused suspicion as to the quality of the well water. The
Public Analyst reported it to be a very polluted water indeed.
I advised that samples should be taken from all the wells
supplying houses at Top Locks. This was done and the
Analyst reported that all were bad. I should here say that Top
Locks is quite off the route of the Water Company's Main, and
the owners have difficulty in complying with the notices which
were served on them to provide a supply of pure water, as the
Company are reluctant to carry their main so far.
The worst wells have been closed, and others have been
cleaned out. I am quite satisfied that the owners are doing all
they can in the matter, and I fully anticipate that within a very
short time the Company's Main will be carried to Top Locks.
When this is done there will be no part of the district supplied
from wells.
Disposal of Refuse.
I am indebted to our Engineer, Mr. Reginald Brown,
A.M.I.C.E., M.R.S.I., &c., for the following particulars.
(a). Sewage Disposal.
The Sewage enters the Disposal Works at two different
points. What may be termed the high level outfall sewer takes
the Sewage from the District proper. This enters the works by
passing through a small chamber controlled by valves, and thence
into and through a receptacle in which is fixed one of Smith's
Patent Revolving Wire Screens.
This screen consists of a water wheel—driven by the
momentum of the Sewage—which causes an endless band of
wire net to revolve slowly, thus catching and lifting out all
