ARTICLE I. FIRE PROTECTION POLICY
The Fire Protection Design Policy for the City of Hot Springs is as follows:
1. GENERAL
Flow criteria, as stated herein, is intended for the purpose of sizing mains for extensions
from existing facilities where practical (i.e. where the system is capable of delivering the
required pressures and flows) and for the design of large system improvements.
New water line extensions and fire protection facilities, such as mains and hydrants, shall
be in working order and have been accepted by the Utility prior to building permits being
issued to a new development.
The following tables represent the minimum requirements for fire hydrant spacing and fire
flow as outlined in the 2012 Arkansas Fire Prevention Code Volume 1.
§FB105
FIRE-FLOW REQUIREMENTS FOR BUILDINGS

two-family dwellings having a fire area which does not exceed 3,600 square feet (344 m2)
shall be 1,000 gallons per minute (3785 L/min.) for 1 hour. Fire flow and flow duration for
dwellings having a fire area in excess of 3,600 square feet (344 m2) shall not be less than
that specified in Table FB105.1.
EXCEPTION: A reduction in required fire flow of 50 percent, as approved, is allowed
where the building is equipped throughout with an approved automatic sprinkler system
in accordance with Chapter F9 of the International Fire Code.
§B105.2 Buildings other than one-and two-family dwellings. The minimum fire flow and
flow duration for buildings other than one-and two-family dwellings shall be as specified
in Table B105.1.
EXCEPTION: A reduction in required fire flow of up to 75 percent, as approved, is allowed
when the building is provided with an approved automatic sprinkler system installed in
accordance with §903.3.1.1 or §903.3.1.2. The resulting fire flow shall not be less than
4
1,500 gallons per minute (5678 L/min.) for the prescribed duration as specified in Table

ARTICLE II. CONNECTIONS AND EXTENSIONS
1. RELATED ORDINANCES. Ordinances 6264 and 5822 contain the most current
Board Policy related to water and wastewater connections and extensions. The
requirements of those ordinances are included in these water and wastewater
standards by reference. Should those ordinances be revised in the future, then the
replacement ordinances shall govern and shall be used to interpret the affected
sections of these water and wastewater standards.
2. EXISTING CONNECTIONS. Existing water meter boxes, taps, wastewater services,
grinder stations, etc. are not considered new connections. A property owner may
continue to use or re-purpose existing connections if the proposed use meets other
city codes, fire codes, plumbing codes, and Planning Commission and land use or
zoning codes, where applicable.
3. EXISTING SHARED GRINDER STATION USE. Each single family residence shall
provide its own simplex grinder station. In rare occasions when grinder stations are
shared, each connected home shall be built with the electrical services extended to
the grinder station and fully capable of operating the grinder station independently
from the other connected home.
4. EXISTING SEPTIC TANK SYSTEMS. New water connections may be approved for
properties with existing septic tank systems as long as the septic tank systems are
performing properly and the request complies with all other Utility connection
policies. The Utility may require a certification from the local Health Department that
the system is performing properly. If the existing septic tank system is not performing
properly and the Health Department states that repair or replacement of that system
is not practical, then the new water connection must also include a connection to the
Utility’s wastewater system if the wastewater system is available at that location.
5. MAINS MUST BE ACCEPTED. The tapping of a water main or connection to a
wastewater main will be permitted only to those mains that have been officially
accepted by the Utility. The process for acceptance is contained in a later section of
this document.
6. CAPACITY. The location, size, and other details of requested water or wastewater
connections or extensions will be based on service availability, fire protection
requirements, and system capacity. The Utility may require that the applicant
contract with the Utility’s system modeling consultant(s) for an evaluation of the
capacity, pressures, pump station capacity, etc. related to the proposed project.
8
7. MAIN ADJACENT TO PROPERTY. If a water or wastewater main is not adjacent to
the property proposed for service, then if approved by the Utility and if in conformance
with current City extension policy, the property owner (or developer) shall construct,
at their expense, an extension of the water or wastewater main to a point adjacent to
the property proposed for service. Said construction shall be in accordance with Utility
construction standards.
8. CANNOT CROSS PROPERTY LINES. No service lines from one property may
cross other adjacent properties even if in an easement. If property is expected to be
split and sold, then service lines shall be designed and constructed with this in mind
to mitigate potential future conflicts.
9. STREET FRONTAGE. Water and wastewater mains and fire hydrants for public
ownership and maintenance shall be located along public streets and on public
property or public rights of way. Water meters shall be located along city streets, in
public rights of way. Water meters will be placed for a property only if there is a
water or sewer main at that property. Service lines shall extend from the meter or tap
onto the property of the user. Service lines may not be extended along or within the
public right of way to reach the user’s property line.
10. AUXILIARY BUILDINGS. Only one water meter or wastewater connection is
permitted for single family residential lots. However, auxiliary buildings on the same
lot may be connected to the water and wastewater lines that serve the main building
or residence on a lot. Said auxiliary buildings include, but are limited to, a cottage,
garage apartment, shop, garage, or pool building. This exception does not include
two primary homes or construction of a duplex or multi-family building or buildings on
property not zoned or otherwise established for that use. Multiple meters on one lot
shall be approved only for lots approved for said use, see Approved Developments
below.
11. APPROVED DEVELOPMENTS. Only one meter or wastewater connection is
allowed for each lot of record except for projects approved for that use by the Utility.
Approved projects may include duplex, multi-family residential, commercial,
manufacture, storage, mobile home, or industrial developments or educational or
governmental campuses, industrial parks, sports and recreation complexes. The
above uses shall comply with fire protection, wastewater disposal, plumbing
requirements, and with land use, zoning, Planning Commission, and Arkansas
Department of Health approval where applicable. Where multiple connection
developments are approved, they must comply with the development requirements
stipulated in the Design Criteria Section of these standards and the requirements of
the Hot Springs Planning Commission, where applicable.
9
12. MASTER METERS. Unless a master meter is approved by the Utility, each living
unit of a duplex or larger multi-family structure or each commercial unit or space, or
each building in a campus or development, even if leased or rented, shall have
individual meters and wastewater services and taps.
13. LARGE METER CONNECTIONS. Taps larger than 2 inches shall be made by the
developer. The City will inspect the installation. The Developer shall buy all materials
for the tap. Meters shall be provided by the City based on the current price schedule.
14. TRANSMISSION MAINS. No individual services or main extensions may be
connected to a water or wastewater transmission main. If an existing main or service
is connected to a transmission main, no additional services or extensions may be
added to the main or service and the size of that service may not be increased.
15. OTHER WATER AND WASTEWATER SYSTEMS. Water service in developments
shall be solely served by the Hot Springs Water System. No splitting/sharing of
service with other water system(s) in the same development will be permitted.
If customer(s) or developer(s) are not served by the Hot Springs Water System, but is
served by or desires to be served by the Hot Springs Wastewater system, the
customer shall obtain an agreement from the water system they are served by to
provide water usage data to Hot Springs to use to calculate monthly wastewater fees.
Said agreement shall be in a form acceptable to the Utility.
16. ROYAL WATER AGREEMENT. The City of Hot Springs is party to an Operations
and Maintenance Agreement with the Royal Water Public Facilities Board. Nothing
in these water and wastewater connection and extension policies shall supersede
the terms of that agreement. The extension of water mains in the Royal Water
District will be considered by the Utility only when requested in writing by the Royal
Water District Board.
17. EXTENSIONS IN COUNTY OR STATE RIGHT OF WAY. If a water or wastewater
extension is to be placed in a county or state right of way, the developer shall
provide written permission from that agency for the extension including the City’s
perpetual ownership and maintenance.
18. EASEMENTS AND RIGHT OF WAY. All new water or wastewater extensions must
be located in approved, recorded easements granted to the Utility. Standard
easement forms are provided by the Utility.
19. FILL OVER UTILITIES. If a property owner causes or allows fill, pavement, concrete,
a structure, or obstruction to be placed over a utility line or appurtenances without
prior written permission from the Utility, that property Owner shall be responsible for
10
restoring or relocating the damaged utility line as directed by the Utility. If, after
written notice and a 60-day period for the repair or relocation and if, the property
owner has not made the repair or relocation, or has not entered into an agreement
with the Utility regarding the repair or relocation, then the Utility may complete the
repair or relocation and invoice the property owner for said cost. Should the property
owner fail to repay the Utility within 120 days from the date of the invoice for the
work, then Utility shall seek legal remedies for the damages and place a lien on the
property.
20. DAMAGE TO UTILITIES. If a property owner causes, either directly or through
contractors employed by the property owner, damage to utility line(s) or
appurtenances, that property Owner shall be responsible for repairing or replacing
the damaged utility line as directed by the Utility. If, after written notice and a 60-day
period for the repair or relocation and if, the property owner has not made the repair
or relocation, or has not entered into an agreement with the Utility regarding the
repair or relocation, then the Utility may complete the repair or relocation and invoice
the property owner for said cost. However, if the damage results in a wastewater
system overflow, or a water system break or leak, then the Utility may immediately
take action to repair the damage or employ a contractor to repair the damage and
invoice the property owner for the cost of the repair. Should the property owner fail
to repay the Utility within 120 days from the date of the invoice for the work, then
Utility shall seek legal remedies for the damages and place a lien on the property.

6. Location & Protection of Surface & Subsurface Structures.
The approximate location of subsurface structures should be shown on the plans. The
information is shown to provide “guidance” for the Contractor and the Engineer. It does
not guarantee the accuracy or correctness of the locations shown. Furthermore, there
may be structures that are not shown. It shall be the responsibility of the Contractor to
satisfy themselves as to the actual location and nature of subsurface structures.
The Contractor shall make necessary exploratory excavations to determine the location
of underground structures such as pipes, drains, conduits and other structures. The
contractor shall be responsible for contacting the owners of such structures prior to
excavating in the vicinity of these facilities. The contractor will comply with the instructions
provided.
The Contractor shall provide adequate protection and support for all surface and
subsurface structures or other facilities encountered during the progress of the work.
Whenever such structures or facilities are in the same location as the proposed pipe line
or appurtenances, the Contractor shall relocate or reconstruct, the structure or facility to
the satisfaction of the Engineer and Utility. Whenever requested by the Engineer or Utility,
the Contractor shall provide drawings and other plans for supporting or otherwise
safeguarding surface and subsurface structures or other facilities which, in the opinion of
the Engineer, or Utility, may be damaged as a result of the Contractor's work.
The Contractor shall not stop or impede the flow in any pipe, wastewater, surface or
subsurface drain without first making provisions for diverting the flow to the satisfaction
of the Engineer.
If any Utility facility or structure is damaged during the progress of the work, the Contractor
shall immediately notify the appropriate owner. Repairs shall not be made by the
Contractor without the prior approval of the Utility facility or structure owner. All repairs
to wastewater facilities or the construction of wastewater facilities shall conform to the

47
7. Protection of Vegetation.
The Contractor shall not remove or disturb any vegetation except that required for the
execution of the work.
Unless otherwise specified in these specification(s) or in the Plans, the Contractor shall
replace all sod, shrubs, bushes, trees, and flowers disturbed or removed, that are located
upon improved or landscaped public and private property. The Contractor shall replant
vegetation and re-landscape affected areas either by self performing them or employing
someone else to do so. This is to be accomplished throughout the work area as soon as
possible following installation of the pipe lines and appurtenances. All vegetation
damaged during or after removal shall be replaced with healthy vegetation of the same
kind or type. All plants shall be replanted in the original location. The Contractor shall
maintain all such replanted vegetation by the application of water, fertilizers and top soil.
The vegetation
shall be cultivated to prohibit the growth of foreign vegetation until a well developed root
system has been established and transplanted vegetation has overcome the "shock"
resulting from transplanting. All vegetation which dies or becomes unhealthy shall be
replaced by the Contractor. The contour of the ground shall be left as near the original
contour as possible.
8. Excavation & Preparation of Trench.
The trench shall be excavated to the alignment, depth and width specified or shown on
the plans and shall be in compliance with all Federal, State and local regulations to ensure
the safety of the workers.
Open trenches along public streets or roads shall be backfilled as soon as possible and
shall be kept to a minimum length as allowed by the governmental authority having
jurisdiction. This limit may be reduced by the Utility in congested areas.
Discharge from any trench-dewatering pumps shall be routed to natural drainage
channels, storm sewers or as directed by applicable regulatory agencies.
Excavated material(s) shall be placed in a manner that will not obstruct the work,
endanger the workers or the public, and obstruct sidewalks, driveways, roadways or other
structures. Placement of excavated material(s) shall be done in compliance with Federal,
State, and local regulations.
Removal of pavement and road surfaces shall be considered a part of the trench
excavation. The amount of pavement removed shall depend on the width of trench
required for installation of the pipe and the dimensions of the area into which valves,
hydrants, specials, manholes or other structures will be installed. Methods such as
48
sawing, drilling or chipping shall be used to ensure straight lines along removal area(s).
The width of the trench at the top of the pipe shall be the same as that afforded by the
single-pass capabilities of normally available excavating equipment and shall be ample
to permit the pipe to be laid and joined properly and to allow the backfill placement as
specified. Trench widths shall be in accordance with AWWA Standards and/or pipe
manufacturer(s) recommendations (whichever is more stringent). Trenches shall be of
such extra width, when required, to permit the placement of timber supports, sheeting,
bracing and appurtenances in accordance with the safety requirements of the agency
having jurisdiction.
When excavation of rock is encountered, all rock shall be removed to provide a clearance
below and on each side of all pipe, valves and fittings of at least 6”. Once excavation is
completed, a layer of appropriate backfill material(s) shall be placed on the bottom of the
trench, it will then be leveled and tamped.
Should the trench pass over a wastewater line or previous excavation, the trench bottom
shall be sufficiently compacted to provide support equal to that of the native soil or to
conform to other regulatory requirements to prevent damage to the existing installation.
Blasting for excavation shall be permitted only after securing the approval of the Engineer
who will establish the hours of blasting. The blasting procedure, including protection of
persons and property, shall be in strict accordance with Federal, State and local
regulations.
When the subgrade is found to include ashes, cinders, refuse, organic material or other
unsuitable material(s), such material shall be removed to a minimum of at least 6” below
the bottom of the pipe or to the depth determined by the Engineer. The removed
material(s) shall be replaced with clean, stable backfill material(s).
Appropriate traffic control devices shall be provided in accordance with Federal, State
and local regulations to regulate, warn and guide traffic at the work site.
The Contractor shall comply with all Federal, State and local laws and ordinances with
respect to obtaining permits, the deposit of bonds and all other provisions of such laws
and ordinances.
Whenever necessary to prevent caving, excavation in sand, gravel, sandy soil or other
unstable material(s) shall be adequately sheeted and braced. Where sheeting and
bracing are used, the trench width may be increased accordingly. Trench sheeting shall
remain in place until the pipe has been laid and bedded. Where slides or cave-ins occur,
the Contractor shall, at his expense, uncover the line and provide proper bedding and
support for the pipe.
49
9. Pipe Installation.
General. Proper implements, tools and facilities shall be provided and used to ensure the
safe and convenient performance of the work. All pipe, fittings, valves and hydrants shall
be lowered carefully into the trench to prevent damage to water main material(s) and
protective coatings and linings. Under no circumstances shall water main material(s) be
dropped or dumped into the trench. The trench should be dewatered prior to installation
of the pipe. Final site grade should be established prior to installation of underground
utility line(s). This will mitigate the potential to inadvertently reduce the required cover for
buried line(s).
All pipe, fittings, valves, hydrants and other appurtenances shall be examined carefully
for damage and other defects immediately prior to installation. Defective material(s) shall
be identified and removed from the job site.
All lumps, blisters and excess coating(s) shall be removed from the socket and plain ends
of each pipe, the outside of the plain end and the inside of the bell shall be wiped clean
and dry and be free from dirt, sand, grit or any foreign material(s) before the pipe is placed.
Foreign material(s) shall be prevented from entering the pipe while it is being placed in
the trench. No debris, tools, clothing or other material(s) shall be placed in the pipe at any
time.
As a length of pipe is placed in the trench, the joint shall be assembled and the pipe
brought to correct line and grade. The pipe shall be secured in place with approved backfill
material(s).
It is common practice to lay pipe with the bells facing the direction in which work is
progressing, however, it is not mandatory.
At times when pipe laying is not in progress, open ends of pipe shall be closed by use of
a watertight plug.
Before installation of pipe and appurtenances, the trench bottom shall be graded to
provide uniform support of the pipe and appurtenances. In addition the locate wire must
be installed prior to placing the bedding. Shallow depressions shall be made in the trench
bottom to accommodate bell ends.
Cutting of the pipe for inserting valves, fittings or closure pieces shall be done in a neat
and craftsman like manner without damage to the pipe or pipe lining. Torch cutting is not
permitted. All pipe shall be cut at an angle of 90o to the pipe centerline. Cutting at other
angles to provide greater deflections at the joints will not be permitted. Field welding or
welding shall not be permitted except by pipe manufacturer(s).
