got good supply into the city it is delivered at
the northwest corner of it and furthest away
from those locations which are developing most
rapidly in population.
II, The d system 9o,,} Of supply pipes from
mum length and consequently of the
maximum cost, and the cost Of operating the
work would be greater arising from work done
TO overcome the friction in the greater length
of pipe. The total cost of all this work would
probably exceed $500. 000 and as a result we
would have pretty good water works, capable
of supplying 100000 gallons per day.
II We estimate the present rate of supply to
be maintained $50 gallons per head then this
water works would supply $500 persons,
which, at the estimated growth OF population,
would meet the requirements of the city for the
next four or five years. If, however. the con
sumption of water could be reduced to 125 gal
Ions per head it would supply $4,000 persons,
which would probably meet the requirements
of the population for the next eight or ten
years. The water works authorities do not
think 1t practicable to bring down the con
sumption TO any such figures and point to the
continually growing demand per head of other
cities as their justification.
Instead, therefore. of proceeding with ex-
pensve alterations at the present site which.
according TO their views, will be OF only tempo
rary value, they have decided upon new water
works upon new site, which they claim, while
costing more III the beginning, Will be OF more
permanent value, and be a better and more
economical expenditure of the city's funds.
For the purpose of thoroughly explain
AilS JuO pOSillOu VI Iub pTOpOSeu new WdbeT
works site, it will be more convenient to refer to
the map of the city.
Springfield plantation was at first intended
to be the site OF the new water works and
well was sunk on it Following the theory first
propounded by DR.. Stone lone of the members
of this council and now generally accepted as
correct, that the flow of water in The water
bearing stratum is from west to east; then it
became evident that any extension of a con
duIt from the Springfield plantation site north
ward would call for the condemnation of pri
vate property for right Of way at considerable
expense to the city, and that any extension
southwark would skirt the edge of Laurel Grove
cemetery, the drainage from which might filter
into the conduit and thus cause contamination
OF the water; it was. therefore, determined to
abandon this site, and new location on the cor
ner of Styles avenue aud Gwinnett street was
recommended and has been purchased by the
| city
The pumps boilers and wet well or rank, from
| which the water will be pumped, are to be
| placed upon this lot. Starting from the wet
we'll the main conduit intended TO collect the
water from the proposed new wells will COM
merce with an internal diameter of 8 feet and
| be continued both northward along Styles ave
| nue. TO the present water works and southwark
| to any distance which may be required to give
/ the desired quantity of water from wells to be
located along its line, the internal diameter of
| both branches being feet. The wells will be
| placed 900 feet or 1000 feet apart. Each well
| is to be ~ inches diameter, and is estimated to
yield at least 100000 gallons of water
| per day. The section of conduit
| running from the new site to the
| present water works is 5000 feet in length anil
at least ten wells can be sunk and connected
| with (which with the supply from the present
| existing wells should readily yield 100000
| gallons of water per day-but if the supply
| from these should prove insufficient an exten-
| sion OF the conduit southwark could be con
| tlnued indefinitely and could be made to yield
| an ample supply estimated at from Il, 900 600 to
| 20OOJ,OOO gallons per day If it should by any
| chance occur that the water bearing stratum
should fail to give sufficient water (and
| 1t is to the credit Of the engineer that
| he has venuured to look forward
! to a contingency which is not probable accord
| ing TO present lndlcations) river water can be
| obtained by natural flow along the conduit to
| the present water works, and sure supply OBJ
| tanned. as the bottom Of the conduit is to be 3
feet below the low water level of the river. The
whole scheme seems to be well considered and
| very practical in its details. 1t provides for a
supply Of Is 100000 to 20, 900 009 gallons per day
| and the arguments from the data now on hand
| are irreproachable 1t contemplate new
| 42lnch main from the water works
through central line of tht.
| city, intersecting the presar
| principal supply mains on the line of Gwinn &
street. The northern part of the city y
| thus be assured of an ample main capacity, )
| the mains which at present supply all of Il c
city will be devoted to its exclusive use II g
| newer districts and those just building uD, will
| be within easy reach by the proposed new
| principal main. The friction in the mains WI
be much reduced and the annual cost of oper-
alton lessened in consequence.
! In conclusion / would like 10
| confess that while making this investigation
/ have been deeply impressed with the ad -
vantages and value of the proposed new
scheme Along with many others | had doubted
| the wisdom Of spending 50 much of the tax
payers money in this direction when there are
| so many other urgent calls for it. My views
have been modified considerably by examina-
| ton of its merits.
Mr.. Johnson, the engineer is almost unknown
| in this city My impressions are that he is a
| thoroughly capable engineer, we'll qualified to
cope with every phase Of this difficult problem,
| and one who will take deep interest and per
sonal pride in the satisfactory completion of
this work. All of which is respectfully sub
mitted. am yours obediently,
