1.0 EXECUTIVE SUMMARY

The Rickenbacker Air National Guard Base (RANGB) has contracted with Prime Engineering &

Architecture, Inc. (PRIME) to perform a water and sewer system capacity study for the purposes of analyzing the existing systems and ascertain their capacity to accept increased water consumption and sanitary flows during RANGB’s proposed expansion over the next 20 years. In the process of planning for future growth and expansion, the Base found it necessary to understand the effect that such growth would have on the existing 60-year old water and sanitary sewer systems.

PRIME’s goal in performing this study was to define current system limitations and evaluate it for future expansion. The methodology included a review of previous Rickenbacker International Airport studies and reports, of which RANGB’s systems are part. The studies’ results yielded valuable information concerning current flow and supply capacities; an understanding of problems with system operation; and knowledge of current system structural integrity.

In this report, PRIME studied and analyzed existing populations for water capacity and demand. This information was compared to the population growth forecast to determine if the existing systems could accommodate the growth. PRIME has determined that, with some system improvements and modifications, RANGB’s existing water distribution and sanitary sewer should be adequate to handle the proposed new construction and future population growth.

PRIME recommends the following repairs and improvements to the water and sanitary sewer systems:

• Replace approximately 2,600 feet of asbestos cement (TRANSITE) water pipe;

• Replace two segments of 15-inch sanitary sewer pipe;

• Rehabilitate the remaining sanitary sewer pipes with cured-in-place pipe (CIPP) lining;

• Initiate a study of the iron problem in the water distribution system and investigate methods to eliminate high iron concentrations in the system.

The total estimated construction cost for performing all the recommended improvements and connecting any new facilities to the water distribution and sanitary sewer systems is $625,000. The required water tap and sewer charges imposed by the local regulatory agencies are summarized in Chapter 9.

Ohio Air National Guard Project No. NLZG062005

Construction phasing for both the water distribution system and sanitary sewer system should proceed as follows:

1. Replace the TRANSITE water distribution system piping with ductile iron pipe (DIP).

2. Replace the two 15-inch sanitary sewer system pipe segments that do not meet Columbus standards.

3. Rehabilitate 2,260 linear feet of 15-inch and 1,430 linear feet of 8-inch sanitary sewer with cured-in-place pipe (CIPP) lining.

4. Install the sanitary laterals as part of the site development phase for each new facility/building.

5. Install the water service taps as part of the site development phase for each new facility/building.

2.0 INTRODUCTION

2.1 PURPOSE

The purpose of this study is to present a water and sewer capacity analysis and investigate improvement of the current systems.

The Rickenbacker Air National Guard Base (RANGB) is in the process of implementing the Master Plan, dated September 2005, prepared by Prime Engineering and Architecture, Inc. The Master Plan is a planning document, which allows for planned growth of the RANGB for the next twenty years. The proposed population growth for RANGB will require new facilities to accommodate this growth. As a result of this expansion and population growth, increased demands for domestic and industrial water needs, fire protection, and consequently, the need for modifications to the existing water distribution system or design of a new water distribution system are anticipated. The same anticipations are true for the sanitary sewer system.

2.2 SCOPE OF WORK

By Delivery Order No. 0054 dated May 11, 2006, The Ohio Air National Guard authorized Prime

Engineering and Architecture, Inc. (PRIME) to provide investigative services for the capacity analysis and infrastructure improvement of the water distribution and sanitary sewer system located on the Ohio

Air National Guard (ANG) cantonment area at Rickenbacker International Airport, Columbus, Ohio.

The Design Statement of Work requires PRIME to provide a report on options for upgrading the systems in accordance with base population, facility changes/improvement and mission profile for the following phase time lines:

1. Current: 0-5 years

2. Short Range: 5-10 years

3. Intermediate Range: 10-15 years

4. Long Range: 15-20 years

The study results will be based on the September 2005 Base Master Plan forecast and include the following:

• Population study for the Base and each Facility

• Current and proposed Fixture Unit Count for each Facility

• Domestic and Fire Protection Requirements for each Facility

• Schematic Drawings for main, secondary, and lateral distribution systems

Ohio Air National Guard Project No. NLZG062005

• Construction phasing plan with cost estimates

• Tap fees, capacity and other charges will be only required for Phase I (Current: 0-5 years)

PRIME is responsible for collecting, analyzing, and documenting information gathered from Federal, State, Local (city, county & municipal) authorities, Columbus Regional Airport Authority (CRAA) and other agencies as required to determine future growth in the area.

The Ohio Air National Guard (OHANG) will provide drawings of the current water and sewer distribution systems, buildings, and any proposed future facilities. Current service is provided by Franklin

County Sanitary Engineer through the City of Columbus Department of Public Utilities, Division of

Water, Sewers & Drains.

Ohio Air National Guard Project No. NLZG062005

3.0 EXISTING CONDITIONS

3.1 HISTORICAL BACKGROUND

The Rickenbacker Air National Guard Base (RANGB) was opened in 1942 initially as the Lockbourne

Army Air Base, and later as Rickenbacker Air Force Base. In 1980, the Air Force closed the base, and subsequently the military operations were downsized considerably. Currently, a large portion of the land area of the former air force base is owned by Columbus Regional Airport Authority (CRAA); RANGB owns 162.98 acres of land; and Army National Guard owns 159.84 acres of land.

3.2 EXISTING WATER DISTRIBUTION SYSTEM

3.2.1 DESCRIPTION

The existing water distribution system comprises a network of 8-inch, 10-inch, 12-inch, and 16-inch pipes made of ductile iron and TRANSITE (asbestos cement) materials. Many appurtenances such as valves are not working properly and leak due to age. Based on the information gathered from the Franklin County

Sanitary Engineer and the City of Columbus Water Department, waterline delivery pressure to the

RANGB water system is 72 psi, according to the latest pressure tests.

3.2.2 PRESENT WATER USE AND COST

Present water demand and usage costs were derived from an IEMS-Water Summary Report covering the period 1 January 2004 to 1 January 2006. Total water usage for this period was found to be 5,728,500 gallons, or 7,638 ccf. The total usage cost for this period was $16,606.96, or $2.17 per ccf.

3.2.3 PROBLEMS WITH EXISTING WATER DISTRIBUTION SYSTEM

• TRANSITE pipes. City of Columbus Division of Water discourages the use of asbestos cement pipes due to environmental considerations and other factors.

• Aged appurtenances.

• Temporary/permanent repairs made in the past to the water line system that may not have been properly implemented could be causing pressure reduction in the system.

• Iron concentrations in the existing water system.

3.3 EXISTING SANITARY SEWER SYSTEM

3.3.1 DESCRIPTION

The existing sanitary sewer system consists of 8-inch and 15-inch vitrified clay sewers. Two sections of

15-inch sewer pipe are made of reinforced concrete. Most of the sewers are laid at minimum grade

Ohio Air National Guard Project No. NLZG062005 according to the Detailed Sectional Map Composite Utilities drawings provided by RANGB. The major part of the system was constructed in the 1940’s. The system is beset with infiltration/inflow (I/I) problems. Age of the system is one of the major causes for many entry points for I/I. Approximately 25% of the total sanitary flow is collected at a sanitary lift station located north of the Army National Guard cantonment area. From there, these flows are directed to the 15-inch trunk line along Zistel Street and gravity fed to the CRAA sanitary system. The other 75% of the total sanitary flow gravity feeds to the

CRAA sanitary sewer system. PRIME investigated the option of installing a new 15-inch sewer from the

OHANG area to a new trunk line that was proposed in an MS Consultants Master Plan for Rickenbacker

International Airport. However, from discussions with MS Consultants, it was learned that the OHANG area was not included in the tributary area calculations when this trunk line was sized. Therefore, PRIME did not pursue this investigation further.

3.3.2 PROBLEMS WITH EXISTING SANITARY SEWER SYSTEM

• Improper sewer slopes and height of cover

• Cracked, broken, or aging pipes

• Infiltration and Inflow

3.4 RECENT STUDIES OF SANITARY SEWER SYSTEM

3.4.1 SEWER SYSTEM EVALUATION BY R.D. ZANDE AND ASSOCIATES, INC.

A sewer system evaluation was conducted by R.D. Zande and Associates (Zande) from May 1993 through September 1993 for a study area that included the entire former Rickenbacker Air Force Base and the Village of Lockbourne. The results were documented in a 1994 report to the Franklin County Sanitary

Engineer.

The Zande report indicated that the sanitary sewers in the study area exhibited excessive rain derived I/I amounting to at least twice the average daily dry weather sanitary sewer flow. This was due to numerous system defects identified in previous reports including possible cross connections to the storm sewer system. The Zande report recommended elimination of the existing excessive inflow and infiltration. The report also cited improper sewer slope is causing slow movement of solids. The report recommended modifications to the sewer system to transport only the allowable I/I by the City of Columbus design criteria.

Ohio Air National Guard Project No. NLZG062005

3.4.2 CCTV WORK PERFORMED BY AETC ENVIRONMENTAL, INC.

AETC Environmental, Inc. performed closed-circuit televising (CCTV) of the existing sanitary sewer system throughout the RANGB area in 1997. The CCTV results indicate deteriorated segments, broken pipes, and I/I in the sanitary sewer system.

3.4.3 I/I STUDY BY URS CORPORATION

In March, 2002, URS Corporation performed an I/I analysis of sanitary sewer CCTV tapes from the

Rickenbacker Airport area for the Franklin County Sanitary Engineer. The OHANG cantonment was included in this analysis. The analysis results showed deteriorated pipe joints, numerous areas of probable infiltration, offset joints, and medium to heavy deposits in the pipe segments.

3.4.4 STUDIES BY MS CONSULTANTS, INC.

A Water and Sanitary Sewer System Development Master Plan is being currently developed by MS

Consultants, Inc. This Plan addresses the future development of the Rickenbacker International Airport area (RIAA), of which the RANGB is a part. The study addresses future development for commercial, industrial, and warehouse type facilities.

The study recommends eliminating as many of the lift stations and sanitary force mains as possible in the

RIAA and replacing them with new gravity flow sewers. The study also recommends installing new water distribution pipes.

3.4.5 PRIME BASE MASTER PLAN

A Base Master Plan was prepared by Prime Engineering & Architecture, Inc. (PRIME) in March 2005.

The Short Range and Long Range Development plan recommends the following items:

• Land acquisition;

• Facilities demolition and construction.

• Auto and pedestrian circulation improvements

• Addition of new parking lots.

Table 3.1 presents the proposed projects to be constructed in the Short Range Plan, Intermediate Range plans, and the Long Range Plan. Figure 3.1 presents the facilities to be constructed in the Short Range, Intermediate Range, and the Long Range Plan.

Ohio Air National Guard Project No. NLZG062005

3.5 PREVIOUS SANITARY SEWER PROJECTS

The 121st Air Refueling Wing/Base Civil Engineering completed rehabilitation work on the existing sanitary system as detailed in a report dated March, 2003. This work included cured-in-place pipe (CIPP) lining of approximately 1,040 linear feet of sanitary sewer and rehabilitating 17 manholes with cementitious lining.

3.6 JURISDICTION FOR WATER SUPPLY AND SEWERAGE

Currently, the Franklin County Engineer’s Office is responsible for maintenance of the respective sewers and water lines. The City of Columbus is likely to assume the responsibility for maintenance of both the sewers and water lines of the cantonment in the future.

5.0 FIXTURE UNIT COUNT

5.1 FLOW DETERMINATION

Building fixture unit counts in the various buildings were taken from the plans of the existing facilities provided by the Base Civil Engineer. Fixture counts are the number of plumbing fixtures, i.e., sinks, showers, toilets, etc., from which domestic water is used. A summary of these fixture counts by building is presented in Table 5.1.

Estimation of water demand and wastewater flows based on fixture counts is not in the scope of work of this report and should be accomplished by a more comprehensive Water Management Plan for the Base.

Instead, the calculation of domestic wastewater flows in this report will be based on the methodology recommended by the City of Columbus, Division of Sewerage and Drainage (DOSD).

6.0. WATER SYSTEM

6.1 DOMESTIC WATER USE

6.1.1 DESIGN CRITERIA

For evaluation of the capacity of the water system, PRIME used the design criteria specified in “Joint

Departments of the Army and Air Force USA, Technical Manual TM 5-813-1/AFM 88-10, Volume 1, Water Supply, Sources and General Considerations, 4 June 1987”. These criteria require consideration of the following water system parameters for water systems at Army and Air Force installations:

• Effective Population

• Capacity Factor

• Design Population

• Required Daily Demand

• Fire Flow

• Peak Domestic Demand

• Total Water Demand

6.1.2 EFFECTIVE POPULATION

Normally, the effective design population is calculated by taking the resident population at the Base and adding to it an allowance for the nonresident population. However, at RANGB, there is no resident population. For a normal work week, personnel assigned to RANGB work an eight-hour shift and are, therefore, nonresident.

As shown in Table 4.1, the present daily population at RANGB consists of 386 people. Once a month, during UTA weekend event, this population increases to 1350. For this study, we will assume the UTA weekend event population as the effective design population.

Effective Population = Nonresident Population + Resident Population

Effective Population = 1,350 + 0 = 1,350 people

The resulting effective populations for the present, current, short range, intermediate range and long range periods are summarized in the Tables 4.1 through 4.5. The UTA maximum populations are presented in Table 4.6.

6.1.3 CAPACITY FACTOR

Capacity factor is the multiplier applied to the effective population figure to allow for unforeseen factors such as population increases and variations in water demand, uncertainties as to actual water

Ohio Air National Guard Project No. NLZG062005 requirements, and unusual peak demands whose magnitude cannot be accurately estimated in advance.

The capacity factor varies inversely with the magnitude of the population in the water service area.

Capacity factors will not be applied when calculating fire flows, irrigation requirements, or industrial demands. Capacity factors, as a function of “effective population”, are shown in Table 3-1 of the

Technical Manual TM 5-813-1/AFM 88-10, Vol. 1, “Water Supply, Sources and General Considerations, 4 June 1987”. Since our effective population falls under the category “5000 or less”, a capacity factor of

1.5 will be utilized to determine the design population for estimating the domestic water demand.

6.1.4 DESIGN POPULATION

Design population is the population figure obtained by multiplying the effective population figure by the appropriate capacity factor.

Design Population = Effective Population x Capacity Factor

Design Population = 1,350 x 1.5 = 2,025 people

The resulting design population for the present, current, short range, intermediate range and long range periods are summarized in Tables 6.1 through 6.5.

6.1.5 DAILY DEMAND

Daily demand is the total daily water requirement. It is obtained by multiplying the design population by the appropriate per capita domestic water allowance and plus any special industrial, aircraft wash, irrigation, air-conditioning, or other demands. There are no water demands for special industrial, irrigation, or air-conditioning at RANGB. Water is needed for aircraft washing. Per information obtained from the Base Civil Engineer, RANGB, one aircraft wash is performed during a week, utilizing approximately 300 gallons of water per wash cycle. Other demands to the water system are from the deluge pumps and deluge tanks, with a demand of 1,498 gallons per day.

Required Daily Demand = (Design Population x per capita domestic water allowance) +(other demands + aircraft wash needs);

Required Daily Demand= (2025 people x 50 gal/person/day) +(1,498 gal+ 300 gal) = 103,048 gpd

The resulting daily domestic water demand for the present, current, short range, intermediate range and long range periods are summarized are Tables 6.1 through 6.5.

6.2 FIRE FLOW PROTECTION REQUIREMENTS

The fire flow requirement is the quantity of water in gallons per minute (gpm) needed to control an anticipated fire in a building or group of buildings. Fire area is the total floor area in square feet for all floor levels within the exterior walls, or under the horizontal projection of the roof of a building.

Ohio Air National Guard Project No. NLZG062005

The water supply system at RANGB must be capable of supplying the fire flow demand plus normal consumption at residual pressure and for a normal fire fighting duration of 60 minutes. The requirements must be analyzed to determine whether the capacity of the system is fixed by the domestic requirements, the fire demand, or by a combination of both. Normally, where fire flows are relatively high, or required for long duration, and population and/or industrial use is relatively low, the total required water supply capacity will be determined by the prevailing fire flow demand.

6.2.1 FIRE FLOW REQUIREMENTS FOR BUILDINGS

Fire flow requirements in this study are based on “Water Supplies for Fire Protection”, Fourth Edition, published by Fire Protection Publications, Oklahoma State University and “Fire Protection Design

Manual”, Fourth Edition, published by Department of Veteran Affairs. Fire flow was calculated using the information provided in Table 4-A, Appendix A of “Water Supplies for Fire Protection”.

The calculated fire flow may be reduced up to 75 percent when the building is provided with an approved automatic sprinkler system. However, in no case should this be less than 1500 gallons per minute. Tables

6.6 through 6.10 present fire-flow demand for the Base for the different phases covered by this study.

6.2.2 FIRE FIGHTING DURATION

“Fire Protection Design Manual” requires that the fire flow for non-sprinklered buildings must be available for a minimum duration of 60 minutes for buildings exhibiting “favorable conditions”.

Favorable conditions are:

• Non-combustible construction

• Limited exposures

• Ready access to entire building site by fire department apparatus

• Quick response by adequately staffed fire department

Based on the above, this study assumes all buildings at the RANGB exhibit favorable conditions.

Fire-flows for sprinklered buildings were calculated as required by NFPA 13, “Automated Sprinkler

Systems Handbook”, in accordance with the occupancy classification.

6.2.3 FIRE FLOW DEMAND

Fire flow demand is the required flow in gpm at a specific pressure at the site of the fire for a specific period of time. The requirements for the present RANGB installation are tabulated in Table 6.6.

Therefore, the total present fire flows for the buildings is 28,500 gpm for the duration of 60 minutes for each building.

Fire flow = 28,500 gpm x 60 minutes/ 1 hour =1,710,000 gallons/hour
