Q.
What i s your name and where do you live?
A.
3 . Wiley Finney, J r .
Q.
Are you engaged i n a profession and, i f so, what profession?
A.
Yes, I am engaged i n the engineering profession.
9.
What a r e your qualifications, both by education and experience, to practice
I l i v e i n Lexington, Kentucky.
engi neeri ng?
A.
I graduated from the University of Tennessee in 1933 w i t h a Bachelor's
degree i n Engineering, and i n 1948 I received my Master's Degree i n Sanitary Engineering from Harvard University.
The period 1933 to 1954, except
f o r Army duty and study leave, was spent i n the employ of the Tennessee
Department of Public Health where I progressed from Junior Engineer i n the
Sanitary Engineering Division t o Assistant Director of the Division.
I super-
vised from s i x t o eight sanitary engineers in the water supply and sewerage
program.
T h e Division was responsible f o r review and approval o f plans
and specirications f o r proposed water supply, water treatment and water
distribution projects, waste collection and treatment projects, the traini n g of operators and the general public health supervision of water and
waste systems.
During my Army service I was an o f f i c e r i n the S a n i t a r y Corps and served
i n a number of assignments, including those of Chief Sanitary Engineer
for the E i g h t h Air Force and Chief Yanitary Engineer f o r the United States
Strategic Air Forces i n Europe.
Since 1954 I have been eniployed by the firm of Jioward K. Dell, Consulting
Engineers, Inc., of Lexington, Kentucky.
Since being employed by t h i s
firm I have been i n responsible charge of the study of problems i n water
supply and waste treatment, and the design of such f a c i l i t i e s .
I am a registered professional engineer..
Q.
What is the nature of the practice of Howard K. Bell, Consulting Engineers?
A.
The firm has, since 1914, specialized i n the practice o f sanitary engineeri n g as related to water supply, waste collection and treatment, and d u r i n g
recent years we have added municipal gas work and solid waste disposal to
our f i e l d of practice.
We are presently practicing i n the States of
Tennessee, Kentucky and West Virginia, and have members registered i n other
s t a t e s as we1 1 .
Q.
What i s your present position w i t h the firm?
A.
1 am President of the Company.
Q.
As a consultant t o the Public Service Commission have you made a study of
the improvements proposed by the West Virginia Water Company i n this case?
A.

Q.
As a r e s u l t o f these studies, M r . Finney, would you g i v e us your comments
on t h e general concept o f t h e p r o j e c t s covered i n t h e West V i r g i n i a Water

Lo I,hr
wl dt. 1 vu mcri t s o f t h e water pl a n t s i t e s
which have already been discussed i n previous testimony; t h a t i s , the
1
r
Coonskin s i t e and the Triangle s i t e ?
A.
I have visited both s i t e s and from the standpoint of topography, that is,
existing l a n d features, I prefer the Triangle s i t e .
The consulting engineer
f o r the applicant has t e s t i f i e d t h a t the project cost for the Coonskin s i t e
p l a n t would exceed the project cost f o r the T'riangle plant by more than one
million dollars.
This, t o me, i s a very valid reason for selecting the
4
i
I
1
i
Triangle s i t e .
Another reason for the Triangle s i t e i s i t s nearness t o the
4
present water plant and therefore i t s proximity t o distribution mains feedi n g into the system in different directions.
If the Coonskin s i t e is
u t i l i z e d , a single feeder main would have to be constructed from the plant
t o a point near the proposed Triangle s i t e .
This single supply l i n e could
1
be a vulnerable point i n the supply system.
Q.
Would you give us your opinion on the capacity of the proposed f i l t r a t i o n
p l ant?
A.
The water plant i s designed t o provide a f i l t r a t i o n capacity of 40 million
gallons per day a t the conventional f i l t e r r a t e of 2 gallons per minute
per square foot.
I t i s estimated t h a t the peak daily water demand about
the time the p l a n t i s completed will approach 40 million g a l l o n s .
Recent
experience i n water f i l t r a t i o n practice has indicated that dual media
f i l t e r s a r e capable of s a t i s f a c t o r i l y f i l t e r i n g water u p to a rate of
four to five gallons per minute per square foot w i t h minor changes i n pretreatment.
The proposed p l a n t has been designed w i t h dual media f i l t e r s
and the a b i l i t y t o increase f i l t e r rates to four gallons per minute thus
increasing the plant f i l t r a t i o n capacity t o 80 million gallons per day.
T h i s capacity i s estimated t o serve the peak d a i l y demand i n the year 2010.
-5-
The pretreatitlent: f a c i l i t i e s , t h a t
1s
the coagulation and s e t t l i n g basins
a r e planned f o r the i n i t i a l construction t o provide 40 million gallons
per day capacity.
Provisions are made t o add four additional units i n
the future t o increase the pretreatment capacity t o 80 million gallons
per day as needed.
I would normally design the f i l t r a t i o n f a c i l i t i e s w t h a capacity t o
serve the expected demand f o r about 25 years i n the future, which i n
this case would be for 1995, a t which time the pea demand would be
about 60 million gallons per day.
T h i s would result i n the elimination
of four f i l t e r s with associated piping and superstrucutre from the
presently planned contract.
However, i n reducing the f i l t e r capacity
I would a t the same time increase the pretreatment capacity t o 60
million gallons per day by the addition of two coagulation and s e t t l i n g
basins.
I t i s our opinion, however, t h a t the savings accomplished by elimination
of the f i l t e r s will be about equalled by the added cost of two new c l a r i fiers,
I t i s further estimated that the u n i t cost of the addition of
the f i l t e r s will probably exceed the cost per mjllion gallons of adding
additional c l a r i f i e r s .
For these reasons we consider the present balance
between f i 1 ter capacity and c l a r i f i e r capacity to be sound.
Q.
What i s your opinion of the economics of the treatment plant construction
proposed?
A.
The plant is designed for economy of construction as i s consistent w i t h
future maintenance and operation costs.
The contract construction cost
f o r the treatment p l a n t i s approximately $200,000. per million gal ons capac i t y based on the 40 million gallons per day i n i t i a l plant capacity.
The
plant can be expanded t o 80 million gallons per day by the l a t e r addition

Q.
.
Have you made an a n a l y s i s o f t h e transmission main c a p a c i t i e s proposed
t o supply water t o t h e B e l l e area and t o t h e western end o f t h e system?
A.
No, we have n o t made a d e t a i l e d d i s t r i b u t i o n system a n a l y s i s such as
would be necessary f o r t h e s i z i n g o f t h e transmission mains f o r design
purposes.
This e n t a i l s a r a t h e r i n v o l v e d study and I do n o t t h i n k t h a t
t h i s t y p e o f d e t a i l e d a n a l y s i s was contemplated i n my assignment.
I have, however, reviewed t h e design f l o w s i n r e l a t i o n t o the main s i z e s
and t h e mains a r e c e r t a i n l y n o t oversized i n r e l a t i o n t o t h e expected
demands f o r which they a r e designed.
The transmission main t o B e l l e i s s i z e d f o r t h e expected demand i n t h e
year 2010 o r about 40 years l’n t h e f u t u r e .
The mains t o supply t h e
west end o f t h e system a r e s i z e d f o r t h e demand expected i n 1990 o r j u s t
over 20 years hence.
i
The useful l i f e o f c a s t i r o n water mains can reach
100 years o r more so t h e design periods and c a p a c i t i e s a r e c e r t a i n l y
not liberal.
I n view of t h e economics o f t h e t o t a l improvement program
i t appears t h a t t h e main c a p a c i t i e s should be considered as adequate.
Q.
Have you g i v e n p a r t i c u l a r study t o t h e f o r e c a s t s f o r f u t u r e water demands,
and i f so, what a r e your opinions and conclusions.
A.
Yes, I have.
I
A t f i r s t glance, t h e demand curves on E x h i b i t No. 8 seemed
t o r i s e a t a rather rapid rate.
A f t e r r e c e i v i n g t h i s e x h i b i t I requested
t h a t we be f u r n i s h e d an e x p l a n a t i o n o f how t h e curves were prepared.
This w r i t t e n e x p l a n a t i o n was submitted as Appendix C Water Demand and was
-I__
l a t e r discussed by M r . Walter M o r r i s i n h i s testimony on cross examination
on A p r i l 2, 1969.
-7-
I
I
The study showed t h a t the population o f Kanawha C o u n t y has increased only
s l i g h t l y i n the l a s t ten years and t h a t the population of the Charleston
D i s t r i c t has actual ly decreased.
Therefore the population projection
used i n the study showed a r a t e of increase which i s less t h a n that experienced i n the l a s t ten years.
The commercial usage i s shown t o increase a l i t t l e under 14 per cent in
the next twenty years and about 39 per cent i n the next forty years.
The most r a p i d r a t e of increase and the greatest increase in water volume
i s reflected by the study of industrial water usage.
The projection of
the industrial demand, however, i s based on actual estimates obtained from
industries f o r t h e i r anticipated water needs in the year 1985 w i t h a small
additional demand estimated for new Tndustries.
This method certainly
gives added validity t o the r e s u l t s .
One might take issue with the f a c t that a t the year 1990 the industrial
curves break s l i g h t l y i n an upward direction rather t h a n continue in a
straight line increase.
However, i f the growth
in
demand increases on a
fixed percentage basis a logarithmic curve would result and the curve
would become steeper w i t h each passing year.
The validity o f the projections can only be proved or disproved by actual
future growth,
The cost o f water distributed t o the consumer m i g h t ad-
versely a f f e c t the industrial water demands b u t only, i n my opinion, i f
the indivl’dual industries can produce a potable water a t less cost t h a n
they can buy i t .
On the basis of the information available I consider the forecasts f o r
future water usage to be reasonable and not overly optimistic.
I also
t h i n k t h a t an extremely thorough study has been made i n a r r i v i n g a t the
projections.

I have made a cursory review of the construction plans for the water
treatment p l a n t proposed for the Triangle s i t e .
I have heard and studied
a l l the applicant’s testjmony presented t o this Comission and I have
visited the water treatment p l a n t a t Slack Street i n Charleston and the
Belle water p l a n t .
Q.
As a r e s u l t of these studies, Mr. Finney, would you give us your comments
I
on the eneral concept of the projects covered i n the West Virginia Water
Company s appl i cat1 on.
A.
We are n agreement with the applicant’s consulting engineers t h a t the
centra 1 treatment plant i n the Charleston area t o serve Charleston, Nitro,
Belle and the intermediate areas i s the plan o f choice from both the
construction cost and the operating cost standpoints!
_ J
A
We d o u b t that the auxiliary intake a t Chelyan and the raw water supply
line between Chelyan and Charleston i s a necessary feature a t this time.
From information obtained i n studies previously mentioned i t does not
appear t h a t the sanitary quality of the Kanawha River water a t Chelyan
i s s u f f i c i e n t l y better t h a n t h a t i n the Kanawha River a t the mouth of
the Elk River t o j u s t i f y the expense o f the intake and raw water l i n e
a t this time.
There i s a s l i g h t risk t h a t chemical s p i l l s i n t o the river
above Charleston may be detrimental t o the Kanawha River quality a t times,
b u t even a t periods of low flow i n the Elk River, the demand o f water
to be taken f r o m the Kanawha for a number o f years t o come will be small
i n proportion t o the mi’nimum flow n the E l k River t o be mainta ned by
the Corps of Engineers.
We reconmend that the Chelyan intake and raw
water line be eliminated w i t h the knowledge t h a t a minor risk i s being
taken t h a t objectionable t a s t e and other quality degradation may be
encountered on rare occasions.

Q*
What a r e your opinions as t o the r e l a t i v e merits of the water plant s i t e s
which have already been discussed i n previous testimony; t h a t i s , the
Coonskin s i t e and the Triangle s i t e ?
A.
I have visited both s i t e s and from the standpoint of topography, t h a t i s ,
existing land features, I prefer the Triangle s i t e .
The consulting engineer
f o r the applicant has t e s t i f i e d t h a t the project cost for the Coonskin s i t e
p l a n t would exceed the project cost f o r the Triangle plant by more than one
million dollars.
This, t o me, i s a very valid reason f o r selecting the
Triangle s i t e . Another reason f o r the Triangle s i t e i s i t s nearness t o the
present water plant and therefore i t s proximity t o distribution mains feedi n g into the system i n different directions.
If the Coonskin s i t e i s
utilized, a single feeder main would have to be constructed from the plant
to a p o i n t near the proposed Triangle s i t e .
T h i s single supply l i n e could
be a vulnerable point i n the supply system.
Q*
Would you g i v e us your opinion on the capacity of the proposed f i l t r a t i o n
p l ant?
A.
The water plant i s designed to provide a f i l t r a t i o n capacity o f 40 million
gallons per day a t the conventional f i l t e r r a t e of 2 gallons per minirte
per square foot.
I t i s estimated that the peak daily water demand about
the time the plant i s completed w i l l approach 40 million gallons.
Recent
experience i n water f i l t r a t i o n practice has indicated t h a t d u a l media
f i l t e r s a r e capable of s a t i s f a c t o r i l y f i l t e r i n g water up t o a rate of
f o u r t o f i v e gallons per minute per square foot w i t h minor changes i n pre-
treatment.
The proposed plant has been designed w i t h dual media f i l t e r s
and the a b i l i t y to increase f i l t e r rates t o four gallons per minute t h u s
increasing the p l a n t f i l t r a t i o n capac,ty to 80 m i l l i o n gallons per day.
T h i s capacity i s estimated t o serve the peak daily demand i n the year 2010.

The pretreatment f a c i l i t i e s , t h a t i s t h e c o a g u l a t i o n and s e t t l i n g basins
a r e planned f o r t h e i n i t i a l c o n s t r u c t i o n t o p r o v i d e 40 m i l l i o n g a l l o n s
per day c a p a c i t y .
P r o v i s i o n s a r e made t o add f o u r a d d i t i o n a l u n i t s i n
t h e f u t u r e t o increase t h e pretreatment c a p a c i t y t o 80 m i l l i o n g a l l o n s
p e r day as needed.
I would n o r m a l l y design t h e f i l t r a t i o n f a c i l i t i e s w i t h a c a p a c i t y t o
serve t h e expected demand f o r about 25 years i n t h e future,
which i n
would be f o r 1995, a t which time t h e peak demand would be
t h i s case
about 60 m i l l i o n g a l l o n s p e r day.
This would r e s u l t i n t h e e l i m i n a t i o n
o f f o u r f i l t e r s w i t h associated p i p i n g and s u p e r s t r u c u t r e from t h e
p r e s e n t l y planned c o n t r a c t .
However, i n reducing t h e f i1t e r c a p a c i t y
I would a t t h e same t i m e increase t h e pretreatment c a p a c i t y t o 60
m l l l i o n g a l l o n s per day by t h e a d d i t i o n o f two c o a g u l a t i o n and s e t t l i n g
basins.
I t i s our o p i n i o n , however, t h a t t h e savings accomplished by e l i m i n a t i o n
o f t h e f i l t e r s w i l l be about e q u a l l e d by t h e added c o s t o f two new c l a r i fiers,
I t i s f u r t h e r estimated t h a t t h e u n i t c o s t of t h e a d d i t i o n o f
t h e f i l t e r s w i l l probably exceed t h e c o s t p e r m i l l i o n g a l l o n s o f adding
additional clarifiers.

For these reasons we consi'der t h e present balance
f i 1t e r c a p a c i t y and c l a r i f i e r c a p a c i t y t o be sound.
What i s y o u r o p i n i o n o f t h e economics o f t h e treatment p l a n t c o n s t r u c t i o n
proposed?
A.
The p l a n t i s designed f o r economy o f c o n s t r u c t i o n as i s c o n s i s t e n t w i t h
f u t u r e maintenance and o p e r a t i o n costs.
The c o n t r a c t c o n s t r u c t i o n c o s t
f o r t h e treatment p l a n t i s approximately $200,000. p e r m i l l i o n g a l l o n s capac i t y based on t h e 40 m i l l i o n g a l l o n s p e r day i n i t i a l p l a n t capacity.
The
p l a n t can be expanded t o 80 m i l l i o n g a l l o n s p e r day by t h e l a t e r a d d i t i o n
-6-
of f o u r c l a r i f i e r u n i t s which will greatly reduce the capital cost per
million gallons of p l a n t capacity.
Q.
Have you made an analysis of the transmission main capacities proposed
to supply water to the Belle area and to the western end of the system?
A.
No, we have not made a detailed distribution system analysis such as
would be necessary for the s i z i n g of the transmission mains for design
purposes.
T h i s e n t a i l s a rather involved study and I do not think t h a t
t h i s type o f detailed analysis was contemplated i n my assignment.
I have, however, reviewed the design flows i n relation t o the main sizes
and the mains a r e certainly n o t oversized i n relation t o the expected
demands f o r which they are designed.
The transmission main t o Belle i s sized f o r the expected demand in the
year 2010 or about 40 years i n the future.
The mains t o supply the
west end of the system are sized f o r the demand expected in 1990 or just
over 20 years hence.
The useful l i f e o f cast i r o n water mains can reach
100 years or more so the design periods and capacities are certainly
not liberal.
In view of the economics of the total improvement program
i t appears t h a t the main capacities should be considered as adequate.
Q.
Have you given particular study t o the forecasts f o r future water demands,
and i f so, what are your opinions and conclusions.
A.
Yes, I have.
A t f i r s t glance, the demand curves on E x h i b i t No. 8 seemed
to r i s e a t a rather rapid rate.
After receiving this exhibit I requested
t h a t we be furnished an explanation of how the curves were prepared.
T h i s written explanation was submitted as Appendix -C Water Demand and was
l a t e r discussed by Mr. Walter Morris i n his testimony on cross examination
on A p r i l 2, 1969.

The study showed t h a t the p o p u l a t i o n of Kanawha County has increased o n l y
s l i g h t l y i n t h e l a s t t e n years and t h a t the p o p u l a t i o n o f the Charleston
D i s t r i c t has a c t u a l l y decreased.
Therefore t h e p o p u l a t i o n p r o j e c t i o n
used i n t h e study showed a r a t e o f increase which i s l e s s than t h a t experienced i n t h e l a s t t e n years.
The comniercial usage i s shown t o increase a l i t t l e under 14 per cent i n
t h e n e x t twenty years and about 39 per c e n t i n t h e n e x t f o r t y years.
The most r a p i d r a t e of increase and t h e g r e a t e s t increase i n water volume
i s r e f l e c t e d by t h e study o f i n d u s t r i a l water usage.
The p r o j e c t i o n of
t h e i n d u s t r i a l demand, however, i s based on a c t u a l estimates obtained from
i n d u s t r i e s f o r t h e i r a n t i c i p a t e d water needs i n t h e year 1985 w i t h a small
a d d i t i o n a l demand estimated f o r new i n d u s t r i e s .
This method c e r t a i n l y
gives added v a l i d i t y t o t h e r e s u l t s .
One m i g h t take i s s u e w i t h t h e f a c t t h a t a t t h e year 1990 t h e i n d u s t r i a l
curves break s l i g h t l y i n an upward d i r e c t i o n r a t h e r than continue i n a
s t r a i g h t l i n e increase.
However, i f t h e growth i n demand increases on a
f i x e d percentage b a s i s a l o g a r i t h m i c curve would r e s u l t and t h e curve
would become steeper w i t h each passing year.
The v a l i d i t y o f t h e p r o j e c t i o n s can o n l y be proved o r disproved by a c t u a l
f u t u r e growth,
The c o s t o f water d i s t r i b u t e d t o t h e consumer might ad-
v e r s e l y a f f e c t t h e i n d u s t r i a l water demands b u t o n l y , i n my opinion, i f
t h e i n d i v i d u a l i n d u s t r i e s can produce a p o t a b l e water a t l e s s c o s t than
they can buy i t .
On t h e b a s i s o f t h e i n f o r m a t i o n a v a i l a b l e I consider the f o r e c a s t s f o r
f u t u r e water usage t o be reasonable and n o t o v e r l y o p t i m i s t i c .
I also
t h i n k t h a t an extremely thorough study ,ias been made i n a r r i v i n g a t t h e
projections.

A Report on Recommended Water Quality C r i t e r i a -and Uses
Relative t o I n t e r s t a t e Waters in the Kanawha River, by the
Division o f Water Resources, Department o f Natural Resources,
Charleston, West Virginia. T h i s r e p o r t was s t u d i e d only
w i t h r e l a t i o n t o the data on q u a l i t y of water i n the Kanawha
River a t Chelyan and Kanawha City.
-3-
I have made a cursory review of t h e construction plans f o r the water
treatment p l a n t proposed for the Triangle s i t e .
I have heard and studied
a l l the applicant's testimony presented t o this Commission and I have
visited the water treatment p l a n t a t Slack Street i n Charleston and the
Bel 1 e water p 1 a n t ,
Q.
As a result of these studies, Mr. Finney, would you give us your comments
on the general concept of the projects covered i n the West Virginia Water
Company's appl i cation.
A.
W
e are i n agreement w i t h the applicant's consulting engineers that the
central treatment p l a n t i n the Charleston area t o serve Charleston, Nitro,
Belle and the intermediate areas i s the p l a n of choice from b o t h the
construction cost and the operating cost standpoints.
W
e doubt t h a t the auxiliary intake a t Chelyan and the raw water supply
line between Chelyan and Charleston i s a necessary feature a t this time.
From information obtained i n studies previously mentioned i t does not
appear t h a t the sanitary quality of the Kanawha River water a t Chelyan
i s sufficiently better than t h a t i n the Kanawha River a t the mouth o f
the E l k River t o justify the expense o f the intake and raw water line
a t this time.
There i s a slight risk t h a t chemical sp2lls i n t o the river
above Charleston may be detrimental t o the Kanawha River q u a l i t y a t times,
b u t even a t periods of low flow i n the Elk River, the demand of water

Coonskin s i t e and the Triangle s i t e ?
A.
I have visited b o t h s i t e s and from the s t a n d p o i n t of topography, t h a t i s ,
existing l a n d features, I prefer the Triangle s i t e .
The consulting engineer
for the applicant has testified t h a t the project cost for the Coonskin s i t e
p l a n t would exceed the project cost for the Triangle p l a n t by more t h a n one
million dollars.
Triangle s i t e .
This, t o me, i s a very v a l i d reason for selecting the
Another reason for the Triangle s i t e i s i t s nearness t o the
present water plant and therefore i t s proximity t o d i s t r i b u t i o n mains feedi n g into the system i n different directions.
If the Coonskin s i t e i s
utilized, a single feeder main would have t o be constructed from the p l a n t
t o a point near the proposed Triangle s i t e . This single supply line could
be a vulnerable p o i n t i n the supply system.
Q.
Would you give us your opinion on the capacity of the proposed f i l t r a t i o n
plant?
A.
The water p l a n t i s designed t o provide a f i l t r a t i o n capacity o f 40 million
gallons per day a t the conventional f i l t e r rate of 2 gallons per minute
per square f o o t .
I t i s estimated t h a t the peak d a i l y water demand about
the time the p l a n t i s completed will approach 40 m i l l i o n gallons.
Recent
experience i n water f i l t r a t i o n practice has indicated t h a t dual media
f i l t e r s are capable of satisfactorily filtering water up t o a rate of
tour t o five gallons per minute per square f o o t w i t h minor changes i n pretreatment.
The proposed plant has been designed w i t h d u a l media f i l t e r s
and the a b i l i t y t o increase f i l t e r rates t o four gallons per minute thus
increasing the p l a n t f i l t r a t i o n capacity t o 80 m i l l i o n gallons per day,
This capacity i s estimated t o serve the peak d a i l y demand i n the year 2010.

I would normally design the f i l t r a t i o n f a c i l i t i e s w i t h a c a p a c i t y t o
serve the expected demand f o r about 25 y e a r s i n the future, which i n
this c a s e would be f o r 1995, a t which time the peak demand would be
about 60 m i l l i o n g a l l o n s per day.
This would result i n the elimination
o f f o u r f i l t e r s w i t h a s s o c i a t e d piping and s u p e r s t r u c u t r e from the
p r e s e n t l y planned c o n t r a c t .
However, i n reducing the f i l t e r capacity
I would a t the same time i n c r e a s e the pretreatment c a p a c i t y t o 60

I t i s our opinion, however, t h a t the savings accomplished by e l i m i n a t i o n
o f the f i l t e r s will be about equalled by the added c o s t o f two new c l a r i -
fiers.

The study showed t h a t thc p o p u l a t i o n of K a n a w h Courity has increased only
slightly i n the l a s t ten years and t h a t the population o f the Charleston
District has a c t u a l l y decreased.
Therefore the: p o p u l a t i o n projection
used i n the study showed a rate of increase w h i c h i s less t h a n t h a t experienced i n the l a s t ten years.
The commercial usage i s shown t o increase a l i t t l e under 14 per cent i n
the next twenty years and about 39 per cent i n the next f o r t y years.
The most r a p i d rate of increase and the greatest increase i n water volume
i s reflected by the study of industrial water usage.
The projection o f
the industrial demand, however, i s based on actual estimates obtained from
industries for their anticipated water needs in the year 1985 w i t h a small
additional demand estimated f o r new industries,
This method certainly
gives added v a l i d i t y t o the results.
One might take issue w i t h the f a c t t h a t a t the year 1990 the industrial
curves break s l i g h t l y i n an upward direction rather t h a n continue i n a
s t r a i g h t line increase.
However, i f the growth
in
demand increases on a
fixed percentage basis a logarithmic curve would result and the curve
would become steeper w i t h each passing year.
The v a l i d i t y of the projections can only be proved or disproved by actual
future growth, The cost o f water distributed t o the consumer m i g h t adversely affect the industrial water demands b u t only, i n my o p i n i o n , i f
the i n d i v i d u a l industries can produce a p o t a b l e water a t less cost t h a n
they can buy i t .
On the basis of the information available I consider the forecasts f o r
future water usage t o be reasonable and not overly optimistic.
I also
t h i n k t h a t an extremely thorough study has been made i n arriving a t the
projections.
