Mr.. George r Deacon, 70. E:., read q paper
descriptive of the above instruments one OF
which was exhibited In full operation. He
mid that the primary object OF The waste.
water meter Wns stos draw a diagram show
ing in gallons per hour the rate of flow
through It for every instant during the day
and night. Placed under the street upon a
service main forssupplying water toa district
containing 1000 to 1900 persons, 1t affords
information from which the water engineer
may discover the locality Of waste In an easy
and economical manner. 50 The Liverpool
waste water meters were being rapidly in
troduced In Liverpool. There were now
forty.one at work, and eighty-four were
being constructed According to the
last return, made about q month ago,
constant supply had been restored
in thirty-seven waste. water meter dls'
tricts, containing an aggregate population
of $3.50 persons, who took on the average
1873 gallons per head per day for domestic
purposes. The average. consumption IN the
remainder Of the borough, containing 42O,-
824 persons with ten hours supply. and 10
the, out townships, containing 1856 per-
sons, with constant supply, was 1927 gal-,
Ions per head per day for domestic purposes.
The following example of the discovery OF q
leak in private service pipe by means OF the
meter was given: A diagram was taken
from noon on June 10Th to noon on June
18th. At twenty minutes past 3 a. M., on
the 18th, a stop cock between Nos. Z and 8,
,Lanhley Place, being closed, brought down
the consumption from $3.50 gallons per hour.
The consumption again, rose on the turning
on of the stop cock at $50 A. n. The waste
was found to arise from an old
burnt. pipe directly over sewer,
and there were indications that It
had been running for years. The leak had
failed to be discovered during the careful
examinations of inspectors, and If not
proved to exist by the dltterentfating meter
would have remained. After repair another
diagram was taken from noon on the 20th
to noon on the 2lst. The saving due to tie
discovery of this single leak reduced the
consumption over the whole district Of 2,C62
persons by Los gallons per head per day,
and this water, if supplied to manufacturer,
would realize G295 per annun.
"A discussion followed, in which DIR. Bran
well, Sir c. Lanyon, Dir. Rogers Field, the
President, and other gentlemen, took part.
The various speakers were agreed as to the
merits of the meter and consequent improve.
ment which would ensus by it's Introduction
in facilitating the adoption of constant wa
ter-supply in large towns. Sir 9. Lanyon
said be knew OF no place where the: meter
could be introduced with more benefit tnan
In Belfast, and expressed a wish that its use
would be shortly adopted. The President
was of opinion that the introduction into
every house of cheap meter OF some de-
scriptiou, answering the same purpose, would;
be a great advantage. t .s
