uation to the next adjacent lot or building
tract.
Provision for continuation to the next adjacent
properties as set forth above shall always be

is due, applied against the final bill for services
rendered, upon termination of the contract. The
City will not pay interest on such deposit funds.

OR GROUPS OF INDEPENDENT SINGLE CUSTOMERS
A. GENERAL .
This section shall apply only to Single Customers or
groups of Independent Single Customers requiring system
extensions to satisfy the requirements of Point of Ser-
vice for connection to the City's water or sewerage
systems, and it shall specifically exclude extensions
for Subdivisions which are covered in Section VI.
Extensions of the City's water or sewerage systems or
both under the provisions of this section of the poli-
cies which is in addition to the extensions required
for Point of Service, shall be at the discretion of
the Director of Utilities, subject to approval by the
City Manager, but, in any event, the entire costs of
the extensions in excess of Point of Service allowances
shall be paid by the customers whose service lines are
directly connected to the extensions.
B. METHOD OF PROCEDURE.
Where one or more Single Customer desires that the City
extend either its water or sewerage systems, or both,
beyond the amounts specified to satisfy the requirements
for Point of Service for their property, they shall make
their request to the City in writing, stating the lot
and block number, name of subdivision and street address
of the property to be served and the type or types of
service required. Each request shall be signed by all
property owners initially requesting service and their
signatures shall be identified with the property they
desire to be served.
Upon receipt of such request, the City Manager will in-
struct the City's Engineer(s) or Director of Utilities
to prepare an estimate of the cost of the extensions
beyond the Point of Service which shall include actual
construction cost plus an allowance of ten percent (10%)
Page 19
R 0-2<-711
water main extension including all appurtenances,
water service connections, and service sewers,
shall first be determined, to which is added 10%
for the group of participants total extension cost.
2. The participants total extension cost shall be
proportioned to the individual single customers
by a combined relationship of individuals "Front
Footage" as well as distance from prior termi-
nation of system as follows:
a. The distance from prior termination of system
to the proposed service connection location
shall be determined for each participant and
all these distances shall be added together.
b. The Front Footage length of all participants
shall be added together.
c. The combined total of a & b above shall be
divided into the individual totals of distance
from prior system plus front footage, thus
providing the factor which when multiplied by
the group of participants total extension costs
gives the individual's share.
3. In addition to extension costs thus determined,
the customers shall also pay the Connection Charges
and meter deposits as provided in Section IV and
provide their own sewer service line and/or water
connection to the meter.
D. SUBSEQUENT CONNECTIONS TO EXTENSIONS PAID FOR BY SINGLE
CUSTOMERS OR GROUPS OF SINGLE CUSTOMERS.
When intermediate customers between the last previous
Point of Service and the extended Point of Service re-
quest and pay the standard Connection Charges plus
extension charges, the City will refund to the initial
customers who paid for the extension, the pro-rata sum
that the front footage of the intermediate customers
property bears to the total feet of the extension until
the full amount advanced to the City for the extension

acceptance of the facilities for ownership and
operation by the City to the Developer.
C. EVALUATED PRICES.
When the City participates in the cost of facilities for
oversizing or for any other reason, separate bid items
shall be set up to reflect the cost to the City when such
separate items can be feasibly determined. In the absence
of such specific bid prices, the price shall be deter-
mined by using a current bid price or city engineer's
estimated price.
D. DEVELOPER PAYMENTS.
When any extension or improvement to the water and/or
sewerage system is to be installed under Contract be-
tween the City and a contractor, the cost of which is
to be paid wholly or partially by a Developer, the

until after the City has received the full amount due
from the Developer, either in cash to be placed in
escrow or by irrevocable commercial letter of credit

ll. The fOllowing design practices shall be considered
as generally applicable, but they may be modified by
concurrence of City's Engineer(s) and Director in
specific cases where they are impractical.
No sewers other than Service Sewers and House Sewers
shall be less than six (6") inches in diameter.
Service Sewers and House Sewers shall not be less
than four (4") inches in diameter and shall approach
the "Lateral Sewer" on at least a one (1%) percent
grade.
All Lateral and Approach Sewers shall be designed
with hydraulic slopes sufficient to give mean
velocities, when flowing full or half-full of not
less than two (2.0') feet per second based on Kutter's
or Manning's formula using an "nil valve of 0.013.
Grades which will produce velocities in excess of
five (5') feet per second shall be avoided.
Sewers shall be laid in straight alignment wherever
possible. Where horizontal curvature must be used,
the smallest radius shall be one hundred (100') feet.
Manholes shall be constructed at all changes in
alignment, grade or size of sewer intersection of
other sewers except Service Sewers and at the ends
of all sewer lines that will be extended. Inter-
secting sewers shall enter the manholes at the
crown line or top of the intersected or main sewer
and the inverts of all manholes shall be formed
concave to fit the connecting sewer pipes.

ufactured of metal having a tensil strength of 21,000 p.s.i. and modulus of rup-
ture of 45,000 p.s.i..
Thickness of the pipe shall be not less than is required for an
internal working pressure of 150 p.s.i. and for installation with 3~ ft. of cover
in trench condition "A", flat bottom trench with un-tamped backfill, computed in
accordance with A.S.A. A 21.1-1957, "Manual For The Computation of Strength and
