I. AirportDescriptionPinalAirpark(AirportorMZJ)issituatedapproximatelyfivemilesnorthwestoftheTownofMaranaandapproximately30milesnorthwestoftheCityofTucson,Arizona.TheAirportisapproximatelyonemilewest of Interstate 10, just north of the Pinal/Pima County line. The elevation of the Airport isapproximately1,891feetaboveMeanSeaLevel(MSL). WhilePinalAirpark isownedbyPinalCounty,theAirportiscurrentlyleasedtoMaranaAerospaceSolutions.Pinal Airpark primarily serves as an aircraft storage andmaintenance facility forMarana AerospaceSolutions, but other users such as theDepartment ofDefense,ArizonaArmyNationalGuard, and aflighttrainingschoolutilizethefacilityaswell. TheAirport isheavilysecuredandmonitored24hoursdaily,and isnotcurrentlyconsideredapublicuse facility. The20112015NationalPlanof IntegratedAirportSystems(NPIAS)classifiesMZJasaGeneralAviationAirport.The airfield consistsofone asphalt concretepavement runway (1230) approximately6,850 longby150wide.Therunwayisservedbyoneparalleltaxiway,andfourconnectingtaxiways.AllfacilitiescanbeseenintheAirportLayoutDrawing(assubmittedbySFCEngineeringCompany1991)inAppendixA.Anaerial imageof thesite titled,AirportOverviewDrawing, is includedaspage2of thisreport.ThecurrentAirportReferenceCode(ARC)forMZJisApproachCategory/DesignGroupDV.

III. Water&SewerInfrastructureIndexMapping provided byMarana Aerospace Solutions (MAS)was used to index the existingwater andsewernetworks.The listwassupplementedwith informationgatheredduringasitevisitattendedbyrepresentatives from Dibble Engineering, Pinal County, andMAS on August 30, 2012. ThemappingprovidedisincludedinAppendixA.

A. WaterDistributionNetworkTheexistingwatersystem,asdescribedbythecurrenttenantsoperatingstaffandschematicdrawings,generally consists of two (2) active wells, a storage reservoir, three (3) booster pumps, ahydropneumatic tankandaircompressor,achlorinedisinfection system,approximately23,000 linearfeet of six to twelveinch distributionmains, and approximately 35 fire hydrants. Annual and dailydemands of the water network were not available at the time of this assessment and were notevaluated.

IV. VulnerabilityAssessmentThe water and sewer infrastructure are evaluated based on the criteria discussed below. Thevulnerability of the system components are identified inAppendixB andAppendixC. The items arediscussedbelow.

A. LifeSafety&PublicHealthConcerns

Several itemsobservedraise lifesafetyandpublichealthconcernsregardingfireprotectionandwaterquality. Infrastructure identifiedwiththisvulnerability iscriticaltotheoperationofthewaterandfireprotectionsystemsandcomponentsrelatedtotheprotectionofpublichealth.

1. FireProtection/NonPotableConnectiona. Pressure

It isunknownhowthesystemwillrespondtoasubstantialfireflow.Thecurrentoperatingpressure isset intherangeof30 50psi,whichmaynotbesufficienttomeetfireprotectionrequirementsatalllocationswithinthesystem.TheArizonaDepartmentofEnvironmentalQuality,EngineeringBulletin10,Guidelines for the Construction ofWater Systems, Chapter 7.C.2 requires that public water supplysystemsmaintain20psiatall locationsandunderallconditions, includingfireflow.AppendixBofthe2012InternationalFireCodeasadoptedbyPinalCountysetsforthrequirementsforfireflow.Iftheoperatingpressureneedstobeincreasedtomeetfireprotectionorotherrequirements,thenthesystemmayexperienceanincreasedfrequencyofpipefailuresandleaks.

AWaterMasterPlan is recommended to evaluate the fire flow andpressureneeds and thecapabilityoftheexistinginfrastructuretomeetthepressurerequirements.

b. DurationThe steel tank reservoirmay not have sufficient capacity tomeet fire flow duration requirements.AppendixBofthe2012InternationalFireCodeasadoptedbyPinalCountyestablishesfireflowdurationrequirements. Ifthestoragecapacity is insufficient,thenthesystemcanbesupplementedbythe250gpmpumpingcapacityofpotablewater fromWellNo.3and the750gpmpumpingcapacityonnonpotable fromWellNo.1. Inorderto feedthenetwork fromWellNo.1,agatevalvemustbeopenedmanuallyatthepumphouse.IntroducingnonpotablewaterproducedfromWellNo.1willrenderthe



distribution network nonpotable until the lines are flushed and disinfected and meet ArizonaDepartmentofEnvironmentalQuality(ADEQ)waterqualitystandards.Ifthetankstorageisinsufficientorifwellorboosterpumpsfail,thenadequateflowandpressuremaynotbeachievedatthehydrants.

AWaterMasterPlanthataddressesrequiredfireflowdurationandthesystemsabilitytomeetthedurationrequirementisrecommended.

c. HydrantSpacingHydranttypeandspacingmaynotbesufficienttomeetcurrentfireprotectionstandards.AppendixCofthe 2012 International Fire Code as adopted by Pinal County establishes fire hydrant spacingrequirements. The existing hydrants in the network are not of uniformmanufacture, some of thehydrantsat theAirportareoutof service,andmosthave receivedminimalmaintenance.Thismakesspare parts stocking and periodicmaintenancemore difficult and increases the potential for failureduringadverseoperating conditions. Ifexistinghydrants thatare stilloperabledonotmeet requiredhydrantspacing,thenadequatefireflowprotectionmaynotbeavailablewhereneeded.

DevelopingaWaterMasterPlanisrecommendedtoidentifyhydrantspacingrequirementsandthesystemscomplianceornoncompliancewiththatspacing.

ItisrecommendedthattheAirportadoptuniformstandardsforhydrants,suchasAWWAC502.2. WastewaterCollection

Theexistinggravitysewercollectionsystem isoperational.Typicalsewerpipelineconstructionofthe period utilized practices thatmay result in significant system leakage. Leaks can occur atseparatedjoints,missinggasketsatjoints,andatcrackedorbrokenpipes.Leachatefromaleakingsewersystemhasthepotentialtoeventuallycontaminatetheaquiferandgroundwatersupply.

Aconditionassessmentof theexisting sewer system is recommended to identify locationsofleaksandbrokenpipes.

ASewerMasterPlan isrecommendedtobedevelopedtoensurepipesizes,slopes,andcoveraresufficientfortheneedsoftheAirport.

B. SystemRedundancy&ReliabilityThe system was also evaluated for redundancy and its reliability to meet required demands.Infrastructureidentifiedwiththisvulnerabilityisnecessaryforthesystemtocontinueoperationsduringfailureelsewhereinthesystem.

1. WaterSupplyCurrently,thesystem issuppliedbyonewellthatproducespotablewater,WellNo.3.Asecondwell,WellNo.1, isavailable,butproducesnonpotablewaterwhich, if introduced to thenetwork,wouldresultinnoncompliancewithADEQdrinkingwaterqualityregulations.

AWaterMasterPlan is recommended thataddresses redundancyof thenetwork,whichmayincludeasecondpotablewaterwellthatprovidesaredundantwatersupply.



2. WaterStorageThesystemhasonesteeltankreservoir.Withoutdemanddataormetering,theadequacyoftheexistingstoragetanktomeetdiurnalsupplyandfireflowdurationdemandrequirementsisunknown.

A Water Master Plan is recommended that addresses the adequacy of the water storagereservoirtomeetcurrentdomesticandfireflowdemands.3. BoosterPumpingCapacity

Threeboosterpumpsprovideforredundantoperationifpumpfailureoccursorifonepumpisremovedformaintenance.Capacity for thepumps tomeet fire flowpressure requirements isunknownat thistime. As the booster pump system continues to age, obtaining and stocking replacement partswillbecomeincreasinglymoredifficult.Thepumpmotorsareacrossthelinetypewhichcausemorestressonthepumpshaftthansoftstartertypepumpmotorsthatareavailabletoday.

AWaterMasterPlanisrecommendedtodetermineboosterpumpingcapacityneeds. Anewboosterpumpstationwithcomponentsthatmeetcurrentstandardsisrecommended.

4. WaterDistributionSystemIntegrity

Sufficientloopingandisolationabilitymaybepresenttoallowisolationintheeventofmainbreaks. AWaterMasterPlan is recommended todetermine the capabilityof theexistingnetwork to

deliver required domestic and fire flow demands. Frequency of pipe failures in the existingsystemmayincreaseastheoperatingpressureofthesystemisincreased.5. SewerSystem
