2017 Edition
RECOMMENDATION:
Fayetteville City Staff recommends an Ordinance amending the city code and adopting the
Standard Specifications for Design and Construction of Water Lines and Sewer Lines, 2017
Edition.
BACKGROUND:
The most recent version of the Standard Specifications for Design and Construction of Water
Lines and Sewer Lines was adopted in 2012. Several changes are recommended by City staff
and the Arkansas Department of Health (ADH) since 2012, and a new 2017 version has been
developed to include these changes.
DISCUSSION:
Revisions and addendums to the Standard Specifications for Design and Construction of Water
Lines and Sewer Lines, 2012 Edition are proposed to increase flexibility in minimum water main
sizing, increased acknowledgement of cost -share opportunities, reduce costs, and unless
specified otherwise, all materials will be 100% USA Domestic.
Based upon meetings with City staff and input from the public, a list of proposed changes has
been formulated. Due to the volume of changes proposed, the ADH has required that the 2012
edition be replaced with a new 2017 edition, in lieu of revising the 2012 edition. The ADH has
further required that the 2017 edition be sealed by the Utilities Engineer. The ADH has reviewed
the proposed 2017 edition and has stated that ADH will approve upon receipt of the final
document.
The Water, Sewer & Solid Waste Committee reviewed a draft in July 2017. Such draft has been
updated in July 2017, please see the attached spreadsheet of proposed changes.
The revised document was discussed at the August 8, 2017 Water, Sewer & Solid Waste
Committee Meeting. The committee voted 3-1 to forward the document to the full council with a
recommendation for approval.

Improvement" shall be eight (8) inch diameter as defined in Chapter 151 of the City of
Fayetteville Unified Development Code. Unless documented and approved otherwise by the
City, the minimum size water main installed by development shall be eight (8) inch diameter.
Minimum water line sizes less than eight (8) inch diameter will receive special consideration
in situations such as existing areas of six (6) inch water lines. Such special consideration will
be based upon engineering calculations for domestic and fire flow demands, existing
infrastructure, water modeling, water age and water quality and as follows.
Four (4) inch diameter lines shall be the minimum water line size that may be approved for
special conditions such as "short" cul-de-sacs as determined by the City or rural water
extensions, provided such lines could not be reasonably extended in the future to provide
service to adjacent property and where a larger line is not needed to provide either fire
protection or adequate domestic flows.
Two (2) inch domestic water service extensions may be granted by the Utilities Director.
All water lines less than eight (8) inches in diameter require approval from the Utilities Director
and subsequently the ADH.
B. The minimum line size requirement for the provision of fire protection shall be based upon fire
flow calculations including the flow for the private fire line/sprinklers in addition to the flow
required at fire hydrants, water modeling calculations and as follows. The minimum line size
requirement for the provision of fire protection shall a looped six (6) inch line or, in the event
of a dead end line, an eight (8) inch. This minimum requirement shall apply regardless of the
theoretical flow capacities existing in the system. Lines larger than six (6) inch looped and
eight (8) inch dead end may be required if larger lines are needed to provide domestic and/or
fire flow demands based upon engineering calculations and/or water modeling.

applicability of the estimated flow volumes provided.
The following shall be used as a guide:
a. Average Design Flows:
1) Single Family Residential: The average design flow for single family dwellings
shall be one hundred (100) gallons per person per day.
2) Multifamily/Commercial/Industrial/Institutional: Based upon Table 1 Section
2002-1.10 within these specifications unless modified by technical information
either submitted by the Owner and approved by the City, or developed by the
City. These flow volume guidelines may be modified at the City's discretion
as project location specific.
b. Peak Design Flow
1) Single Family and Multifamily Residential: The peak design
flow for a single family development shall be calculated as
follows:
Peak Flow = (Avg. Flow)18 +
P]
4+-�
Where P is equal to the total Design Population in thousands.
2) Commercial/Industrial/Institutional: The peak design flow from
commercial, industrial or institutional developments shall be the
average daily flow determined multiplied by 2.5. The peak
design flow shall not be less than 90% of the peak water demand
or exceed the flow limits of the water meter supplying the
facility.
