Re: Army CreeX Feasibility Study

Dea- Ellen:

As a followup to our recent telephone conversation, Ihave enclosed copies of several documents which demonstrate thatany "shortfall" at Artesian Water Company's Llangollen Well Fieldhas been more than satisfied by interconnections and new wellsalready placed into service by Artesian. These documents, whichare formal submissions by Artesian to the Delaware Public ServiceCommission, further support the discussion on pages 2-4 and 2-5 ofthe Army Creek Feasibility Study submitted by New Castle Countyunder cover letter dated March 7, 1986.

Please note that the attached index provides a fullerdescription of the enclosed documents. Do not hesitate to contactme if you have any questions concerning this matter.

Very truly yours,

Wm. Roger Truitt

ORIGINAL.--> TESTIMONY OF BANGALORE T. LAKSHMAN, P,E. (Red)

Q. Please state your name and t.'dress.

A. My name Is Bangalore T, Lakshman. I reside ac 22 Chiming Road, New

Cascle, Delaware,

Q. What is your occupation?

A. I am Chief Engineer of Artesian Water Company.

Q. Please provide a summary of your educational and professional

background.

A. I was awarded a B.S. degree in civil engineering from the Uni-

versity of Mysore, India; a master's degree in water resources

development, leading to specialization in ground water and surface r

water hydrology, from the University of Roorkee, India; and a

master's degree in civil engineering, leading to specialization in

water resources, hydraulics and environmental engineering, from the

University of Delaware, Newark, Delaware1,

Upon graduation from college, I served as a junior engineer

for the Public Works Department, Mysore, India, until 1964. At

that time I Joined the faculty of the University College of En-

gineering, Bangalore, India, and started teaching until 1963, Then

in 1968 I became a research fellow and teaching assistant at the

University of Delaware while obtaining my M.S. degree in civil

engineering. Since October 1971, I have been employed by Artesian

Hater Company—first as its hydraulics and water quality engineer

and in 1973 I was promoted to my present position as chief engineer.

While employed at Artesian, I have completed numerous assign-

ments in th.e area of water resources development, water quality and

) management. I have performed several cost analyses and feasibility

studies for acquiring private water systems, as well as feasibility

Engineers, Delaware Society of Professional Engineers, National

Hater Well Association, and International Hater Supply Association. .

I served as president of the Delaware Society oi Professional

Engineers (New Castle Chapter) as well as ics Secretary, State

Director, President Elect, and Past President during the period

1977-1982.

Q. Have you published any articles or technical papers in the area of

water resources, water quality, supply, operation an: management?

A. Yes. I have several publications to my credit. A list of them can

be found In the attached supplemental Statement of Qualifications

(BTJ. Exhibit 1).

Q. In what areas do you propose to present testimony today?

A. My testimony will focus on Artesian Water Company's water resources

development and management, available supply, customer demand,

operation, water quality management and related aspects.

Q. Please briefly describe Artesian's water system,

A. Artesian Water Company's water system extends over 90 square miles

in the northern part of Hew Castle County. It serves about 36,500

customers covering a population of over 130,000 people. Its primary

source of supply is ground water, and it has 41 operating

wells with a total theoretical capacity of 15.5 million gallons per

day. The Company has 17 storage tanks with a total systen storage of

27 million gallons, of which about IB million gallons is considered to

be a live storage. The water system is divided Into seven service

levels to provide acceptable pressure gradients to Arteslan's

customers who are located at ground elevation ranging fron sea

level to elevation 420. It has 12 booster punping station!. The

water systen consists of about 510 miles of pipe lines fr:r, 2" to

20" in diameter and about 1.5CC hydrants. Artesian has four direct

interconnections wich the other water purveyors in the area which

will help augment its supply up to 3.6 million gallons per day. During 1981

Artesian 'a average daily demand and peak day demand amounted Co

11.3 million gallons and 14,5 million gallons, respectively. In

addition, Artesian is also considering developing new interconnec-

tions with the Chester Water Authority and the City of Hilmingcon

to further augment its source of supply to meet its future customerdemand,

Q. Could you briefly describe the operation of Artesian1 s watet nysten?

A, Artesian derives about 702 of its ground water supplies from itsrwells located in the coastal plain. The remaining 302 of its wells

are in the Piedmont area, The water supplies from the coastal

plains has low pH and high carbon dioxide and is considered to be

soft water, The water supply from the Piedmont area has relatively

high pH, low carbon dioxide, and is considered to be hard water.

Therefore, Artesian has to treat its source of well supplies wit*.-

aeration, pH adjustment, chlorlnation and flouridation to meet

State as well as Federal water quality standards. Three of its

wells have to be treated for iron through an iron removal plant to

meet the regulatory standards. Artesian has a complex water system

since it has to treat its water supply In 16 different places.

Therefore, Artesian's operation is manned around-the-clock in three

6-hour shifts. The operators are guided by the fluctuations in

only up to a maximum of 2 ngd from this wellfield. In this connec-

tion Artesian has filed a suit against the New Castle County govern-

ment seeking substantial aaoagcn.

Q. Since the time of curtailment of pimping from Llangollen, what did

Artesian do in developing additional ground water supplies?

A. Since 1973, the year in which Artesian was asked to curtail the

•mount of pumpage from its Llangollen wellfield, several studies

have been commissioned by Artesian to assess potential veil sites

and to explore for additional and alternate sources of supply, A

list of studies commissioned in this connection Is nosed in BTL

Exhibit 2.

The studies have identified the locations of potential new

well sites. Artesian has generally proceeded in accordance with

the studies' recommendations and drilled a series of exploratory

test wells. Since 1973 Artesian has drilled as many as 140 ex-

ploratory test wells and constructed 16 production wells. The

total capacity of well supplies developed from this intensified

exploration program equals some 9.5 million gallons (6,f''i gallons•

per minute). A schedule showing the yearly well exploration and

development statistics is attached as BTl Exhibit 3,

Q. Has Artesian made a significant financial commitment to explore for

new sources of ground water supplies?

A. Yes, it has. The importance with which Artesian views its well

supply exploration program is evidenced by its financial commitment

in excess of $1.3 million, not including concomitant expenditures

for supply mains, treatment facilities, etc. A statement showing

Artaslan's capital expenditures in this regard is attached as BTL

City of Wllmlngton and one Interconnection with Wilmington Suburban

Water Corporation. The location, date of construction, and capacity

of the existing and proposed interconnections are 11,"..id in BTL

0,. In the absence of interconnections and purchased water, what alter-

natives does Artesian have in meeting future customer demand?

A. In the absence of purchased water through interconnections, to meet

ongoing future customer demands Artesian has to either Halt the

supplies to its customers or develop expensive alternate sources of

supply.

Q, Would you please describe the kind of procedure and practice

Artesian follows in making decisions as to the purchase of water

through Interconnections.

A. Artesian does have a set of procedures and guidelines for making

decisions as to the aspect of periodic purchases of water from its

interconnections. Normally I set those guidelines for the benefit

of operating supervisors and operators, These guidelines are

reflected in my periodic memoranda to concerned operating personnel

concerning use of interconnections, I would like to submit my

latest menorandua in this connection tf~ Exr.lbtt 6,
