Criterion 9A Water Supply by decree

VIEWS: 10 PAGES: 15

									Category 9: Essential Resources

Essential resources, defined as those mandatory services or systems required for the agency’s
operational programs to function. They may be given the same value of importance as a primary
program. Appropriate adjustments may be necessary in the self analysis to adapt the typical
components listed below to the local situation.

For example, when reviewing a water supply system, the evaluation may not be limited to
conventional resources such as water lines and hydrants, but may include alternative resources, i.e.
tankers, ponds, streams, lakes, etc.
Criterion 9A: Water Supply
The resource is reliable and capable to distribute adequate volumes of water and pressures to all
areas of agency responsibility. All areas should meet fire flow requirements for emergencies.

Description
The City of Wilson has a dual-purpose municipal water system. The system can supply enough
water for fire protection as well as meet the daily consumption demand. The municipal water
system consists of a distribution system designed to deliver water throughout the entire city limits
of Wilson and some areas of the county in the extra-territorial-jurisdiction (ETJ). The system is
composed of two water treatment/pumping facilities located on each side of the City of Wilson.
There are five elevated tanks with a combined capacity of five million gallons of water. The
water system also has 2637 hydrants utilized for fire protection within the city. Hydrants are
located approximately 300 to 800 feet apart.

Appraisal
The water system is capable of pumping 30 million gallons of water daily. At present, the highest
peak demand on the water system has been 14 million gallons. In cases of water distribution
emergencies, Wilson Fire Rescue has contracts with all county departments to deliver water by
water tenders to areas in need. The system is adequate and reliable and due to the recent
expansion of our reservoir, water availability is sufficient to meet fire flow requirements in
emergencies.

Plan
Continue research and development of water distribution throughout the city in an effort to
improve our service deliver to the public and fire protection agencies.

Performance Indicators
9A.1   The fire agency should establish minimum fire-flow requirements and total water
supply needed for existing representative structures and other anticipated fire locations.
This information should also be included in the fire risk evaluation and pre-fire planning
process.

Description
Required verses available fire flow is identified in the planning process through pre-fire planning,
hydrant inspections, and flow testing. Hydrant flow test are conducted annually to evaluate the
performance and capability of the distribution system. Test data is entered in the department’s
Fire Central Records Management System (RMS) . Hydrant flow test results are also entered into
GIS applications to map a global picture of the distribution system performance. Pre-fire surveys
are conducted and include the required fire flow based on 100% involvement of the structure
surveyed. Wilson Fire/Rescue Services utilizes the National Fire Academy fire flow formula to
determine required fire flow for all structures; length x width  three. The department’s risk
analysis software “VISION” also calculates the required fire flow requirements, evaluates the
available water supply based on inputted data and rate the water supply for each survey facility as
sufficient available water or insufficient available water.


Appraisal
In 2004, ISO randomly inspected hydrants within the WF/RS fire district and rated its water
supply system, which received 37.20 points of a possible 40 points. This equates to a 93% rating
conducted by a third party assessment. Tracking fire flow requirements with the utilization of
GIS and through individual pre-fire planning has proven both adequate and beneficial to evaluate
the capabilities of the distribution system. In 2001, this application was used to show areas
within the distribution system that did not meet the needed fire flow for that area. This area
underwent needed upgrades to meet the fire flow demands. This case history shows how this
system has been utilized in the past.

Plan
Wilson Fire/Rescue Services will continue to emphasize the importance of determining fire flows
for structures and continue inspections and testing of hydrants as part of our pre-incident survey
program. WF/RS will continue utilizing GIS applications to monitor data collected from hydrant
test results and address areas needing improved fire flow as surrounding fire flow demands
change or develop.

9A.2 An adequate and reliable fixed or portable water supply is available for firefighting
purposes. The supply is sufficient in volume and pressure to control and extinguish fires.

Description
The City of Wilson maintains an adequate municipal water system for fire protection, along with
industrial and domestic consumption uses, within the city limits and extra-territorial-jurisdiction
(ETJ). Wilson Fire/Rescue Services has three engines and two quints with a portable capacity
that carry 500 to 750 gallons on these apparatus. Wilson Fire/Rescue Services has mutual aid
agreements with the County of Wilson fire departments. These agreements entail county fire
departments to be requested upon dispatch or as needed during emergency incidents. County fire
departments operate water tenders of at least 1000-gallon capacity and engines with a minimum
of 500-gallon capacities. The county departments utilize tanker shuttle quick-dump operations
which enable their units to drop large quantities of water.


Buckhorn Reservoir, Lake Wilson, Wiggins Mill, Finch’s Mill, Silver Lake, and Toisnot
Reservoir supply the City of Wilson water system. The city has two water treatment facilities
located on each side of the city. These facilities together are capable of treating 30 million
gallons of water per day. Each of these facilities holds 4.5 million gallons of water on site. The
municipal water system consists of five elevated water tanks with a combined capacity of five
million gallons. The water distribution currently has 2637 hydrants. The hydrants are flow tested
each year. Any hydrant not yielding a minimum flow of 500 gpm or any hydrant that indicates a
significant reduction from the previous year is reported to the water department for investigation
and/or repair. The City of Wilson also has a contract with the City of Rocky Mount if water is
needed in case of emergency water shortage.


Appraisal
The average daily water demand for 2004 was 9.7 million gallons with the peak demand day of
the year being 14 million gallons. With a production capability of 30 million gallons per day
adequate water supply is available for firefighting. The recent ISO rating process showed for the
water distribution system for our department was 37.20 points, out of a possible 40 points giving
a 93% rating of the water system by a third party survey.
Plan
The department will continue to conduct annual hydrant test to ensure adequate fire flow is
available. It will also maintain a close working relationship with the water department and make
recommendations as needed. The department will continue to participate in mutual aid training
with surrounding departments to conduct water shuttle operations to ensure proficiency.

9A.3 The fire agency should calculate fire flow requirements for proposed projects involving
structures or complexes of structures within their jurisdiction. Significant reductions in required
fire flow granted by the installation of an approved sprinkler system in buildings should be
documented.

Description
Wilson Fire/Rescue Services’ Fire Marshal performs plan review for fire protection features. The
Fire Marshal serves as an integral part of the cities Technical Review Committee (TRC). The
TRC meets once per week to review various site/complex plans to ensure code requirements are
met including adequate water supply for fire protection. The WFRS Inspection/Prevention
Division, under the direction of the Fire Marshal, conducts plan review to calculate fire flow
requirements for future structures and complexes of structures. This plan review process includes
a review of sprinkler installation plans.

Appraisal
The Fire Marshal is responsible for working with engineers and architects to ensure that all fire
flow requirements are met for all building construction. This action is accomplished during the
plan review process. This review process has proven adequate to review future plans for
structures and complexes of structures.

Plan
Wilson Fire/Rescue Services will continue to play an active part in the TRC to ensure fire
protection codes are followed and adequate water supply is present for both consumer and fire
flow needs.

9A.4 There is regular contact with the managers of public and private water systems to keep the
fire agency informed about all sources of water available for fighting fires.

Description
Wilson Fire/Rescue Services maintains ongoing communications with the water department in
reference to status of hydrants, flow problems and areas of testing, etc. Out-of-service hydrant
information is relayed to Wilson Communication Center by the agency (fire or water dept.)
identifying the problem. The communication center in turn announces same over radio to all
stations identifying the problem and placing the hydrant in “out-of-service” status.   After
repairs, the information is relayed by the above stated method that the hydrant is back-in-service.
There are no private water systems in the city of Wilson with the exception of on site storage
tanks to support the sprinkler systems.


Appraisal
Interactions between Wilson Fire/Rescue Services and Water Resources are effective in
communicating needs and/or repairs. The water department has an Emergency Operations Plan
that is implemented pending water supply emergencies.


Plan
Wilson Fire/Rescue Services will continue to evaluate communication between water
departments and communications center and any private facility that may have a system and
make necessary recommendations as needed.

9A.5 The fire agency should maintain current water supply and hydrant maps for its respective
response areas.

Description
All Wilson Fire/Rescue Services stations have access to maps of water mains and hydrants for
their respective response district as well as the entire city. This information is located on the GIS
and Fireview applications located on computers in the station and on first run engines/quints.
This information is utilized for training purposes and fire ground applications as needed. Hard
copies of hydrant maps are located in all stations that identify all district hydrant locations.
Wilson Fire/Rescue Services utilizes hydrant maps for classroom study and in the hydrant-testing
program.

Appraisal
The system works well and allows individual districts to assure that all hydrants in their assigned
district have been tested and maintenance performed. The maps of water main distribution
system located on the GIS is beneficial in the fact that total areas can be viewed to determine
problems in volume and pressure available to suppression personnel. During the summer of
2001, an area of East Wilson was determined to have inadequate water flow in the area of a
school and residential area. Review of the hydrant flow data alerted the water department to
investigate the problem. Investigation findings proved that the distribution system was outdated
and the water department replaced the distribution system in that area within three weeks of data
review.

Plan
Wilson Fire/Rescue Services along with the GIS staff will continue to update hydrant and water
maps as necessary.

9A.6 Hydrant adequacy and placement should reflect the hazards of the locality and the needs
of the fire agency in dealing with those hazards.

Description
The City of Wilson’s ordinance call for hydrant spacing along public streets to be a maximum of
800 feet for residential areas and 300 feet for commercial developments as measured along public
roadways. Fire hydrants on private property shall be spaced utilizing the same distance standards
as public hydrants. All plans for new construction are submitted to the Fire Marshal for approval.
Additional hydrants may be required based upon the use of the facility and its location.

Appraisal
Hydrant spacing is adequate due to 100% of our engines stowing a minimum of 800 feet of five
inch supply hose with the truck company carrying 900 feet. The Fire Marshal assures adequate
hydrant placement for all new construction. Hydrants are located per local and state codes.

Plan
Wilson Fire Rescue will continue to monitor and evaluate hydrant placement during annual
testing and make recommendations accordingly.

9A.7 Fire hydrants should be easily located, maintained and tested so that each hydrant location
is visible and accessible at all times.

Description
All fire hydrants are painted green with the exception of the bonnet, which is painted white and
private hydrants are painted red to distinguish between the two. Hydrants are inspected for
efficiency a minimum of once per year and/or after repairs is made. This includes water-flow
test, operation, and lubrication of caps, maintaining a three-foot distance on all sides and painting.
During the hydrant test process weed abatement is performed to ensure hydrants are accessible
for firefighting operations. The departments budgets a part-time employment position for
assistance with hydrant maintenance.


Hydrants are located per local and state codes. Blue reflective markers are located in roadway in
many areas. These were placed in an effort to assist the driver in locating a hydrant. This
program has been discontinued because of being unable to adequately retain the reflectors in the
roadway due to construction and trucks scraping the roads during snow and ice. Repair orders for
hydrants are forwarded to the water department. The water department assesses the hydrants
needs and repairs are made immediately or the hydrant is taken out-of-service. Once the hydrant
is deemed out-of-service a large red ring is placed over the steamer connection which reads “Out-
of-Service”. All stations are notified of the hydrant status and also advised when the hydrant has
been replaced or repaired.

Appraisal
Our annual hydrant test program has proven adequate to keep personnel in-touch with hydrant
locations and ensuring hydrants are maintained and accessible for firefighting operations.

Plan
Wilson Fire/Rescue will continue to test hydrants on an annual basis. We will evaluate our
testing and maintenance schedule on a regular basis and make necessary adjustments as needed.

9A.8 The fire agency should periodically evaluate the maintenance, inspection and testing to
ensure the adequacy and availability of public or private water for fire protection

Description
Wilson Fire Rescue utilizes suppression personnel to inspect and test new and existing fire
hydrants. New hydrants are inspected by the water department before being released to the fire
department. The hydrant officer installs a number for identification on new hydrants and assures
adequate flow pressures. Once new hydrants have passed preliminary inspection the information
is entered into the data-base to establish a history record which includes maintenance performed
and annual flow tests.

Appraisal
The City of Wilson Water Department along with Wilson Fire/Rescue maintains records of
maintenance performed on all hydrants within the distribution system. Wilson Fire / Rescue
personnel inspect and test hydrants once a year. The water department services and makes repairs
to all City of Wilson hydrants. This coordinated approach to maintaining water supply for both
consumer use and fire protection meets the needs and expectations of both the consumer and
WF/RS.


Plan
Maintenance, inspecting and testing of hydrants will remain a joint effort of the Wilson
Fire/Rescue and the City of Wilson water department. The fire department will continue
evaluating our testing methods and modify as needed.

9A.9 The fire department should develop plans for alternate sources of water supply for those
areas without hydrants, where hydrant flows are insufficient, or in the event of a major disruption
in the water supply capabilities.

Description
Wilson Fire/Rescue Services has mutual aid agreements with the surrounding fire departments.
County fire departments operate water tenders of at least 1000-gallon capacity and engines with a
minimum of 500-gallon capacities. The county departments utilize tanker shuttle quick-dump
operations which enable their units to drop large quantities of water. County tenders utilize
closest accessible water point to shuttle water for a continuous water supply for the dump tank.

In the event of a disruption in the water supply system, the department will conduct relay-
pumping operations. This consists of one engine located at the nearest available water source and
relaying water by five inch supply hose to the engine located at the incident scene. In the event of
a major water disruption in water distribution system, Wilson Fire Rescue has established mutual
aid agreements with County of Wilson departments which will utilize water tenders for water
supply operations.


Appraisal
The resources from county departments, through mutual aid training, have proven effective. In
the past, Wilson Fire Rescue has contracted with county departments in areas that have been
newly annexed until adequate water supply was established and station location provided required
level of service.


Plan
The mutual aid agreements are reviewed regularly and are modified accordingly. We plan to
continue mutual aid training with county departments on a quarterly basis to ensure a state of
readiness in the event our department would have to rely on mutual aid for water delivery.

9A.10 The fire department should have standard operating procedures outlining the utilization
of available water supply.

Description
The department does not have a formally titled water supply standard operating procedure. The
department’s only policy reference to water supply is identified in our Truck Company
Operational Policy. Water supply operations are addressed through applicable training standards
and departmental hose load operations. All suppression personnel are trained in making hydrant
connections as well as connections to standpipe and sprinkler connections. The department
utilizes different procedures for connections to different appliances and for apparatus connecting
to water supply. Hydrant connection operations are benchmarked and every company will be
evaluated annually on these operations.

Appraisal
The City of Wilson Fire/Rescue Services trains on the use of hydrants throughout the year. The
department has not found deficiencies in fire ground operations as a result of not having a formal
water supply standard operating procedure. Training to applicable departmental hose load
configurations and connections have proven adequate to ensure all personnel are well versed in
the utilization of available water supply.

Plan
Wilson Fire/Rescue Services will review our current SOP outlining the utilization of available
water supply for truck company operations.    We also plan to develop an all-inclusive water
supply policy with a completion date of December 2007.
