In urban area of Guilin, the totalgreeningarea is1,930ha, thegreeningcoverageratio is35.1%,and thepercapitapublicgreen space is 6.1m2.

Considering the actual operation ability of these four existing water

treatmentplants,Guilinwillhaveawatersupplygapof181,300~206,900m3/dby2020.To address thiswater shortage, Guilin is implementing an expansion of ChengbeiWaterTreatment Plant, increasing its capacity from 100,000m3/d to 300,000m3/d, which isexpected to be in operation in early 2014. The proposed installation of 37km waterdistributionnetwork(transmissionmain)will link thenewlyexpandedChengbeiWTPtoLinguiDistrictandotherclusterareasinthesouthandwestofGuilin.Itisconsistentwiththeoverallurbandevelopmentplanandthewatersupplyplan.RelatedactivityandduediligencereviewAs a water source for the Bank‐funded pipeline, the expansion of Chengbei WTP isconsideredasanassociatedproject to theBank‐fundedproject.Duediligencereviewhasbeen conducted for the expansion of Chengbei WTP. The expansion of Chengbei WTPincludes water intake facility (200,000m3/d) and water treatment plant (200,000m3/d)besidestheexistingintakeandtreatmentplant,aswellasancillarypipelineandfacilities.Environmental impactassessmenthasbeenpreparedfortheexpansionofChengbeiWTPwhich includes adequate assessment of potential environmental impacts and propermitigation measures to avoid, minimize and mitigate the adverse impacts. This EIA hasbeenapprovedbyGuilinEnvironmentalProtectionBureau(EPB)inNovember2012andisfoundsatisfactorybytheWB.Theconstructionofthisprojectisexpectedtobecompletedby January 2018. As a linkage project, its land acquisition and resettlement has beencovered by the Resettlement Action Plan of this Bank funded project. Therefore, it isconcludedthatexpansionofChengbeiWTPwillnotresultinun‐manageableenvironmentalandsocialimpactsanditisfullyincompliancewithnationallaws/regulations,thuswillnotposeapotentialreputationalrisktotheBank‐fundedpipelinenetworkproject.DrainagePlanAt present, there are five WWTPs in Guilin, including Qilidian, Beichong, Shangyao,Shangyao and YanshanWWTPs. By the end of 2012, the total capacity is 415,000m3/d.According to the drainage plan and the Feasibility study for Guilin IntegratedEnvironmentalManagementProject, the total amountof sewagewithin the catchmentofthesewagesystemsin2020ispredictedtobe381,900t/d.Therefore,itconcludedthatthepresentsewagetreatmentcapacityissufficienttomeetthefuturedemandin2020.However, there are problems for the existing WWTPs that can not provide effectivetreatmentofwastewaterandprotectionofwaterqualityofLijiangRiver.Theseinclude:‐ Relatively low standardadopted inoriginaldesign: the existingWWTPs basically

adopt Class IB standard ofDischargeStandardofPollutants forMunicipalWastewaterTreatmentPlant,someolderonesevenadoptClassIIstandard.DuetotheimportanceofLijiangRiver,GuilingovernmentrequiresallWWTPstomeethighest(IA)dischargestandard,whichbasicallyisstricteronSS,TNandTP(seeTable3).

‐ Nuisanceofodorproblem.TheseexistingWWTPsweremostlyconstructedonurbanfringeareasfewdecadesago.However,withrapidurbanizationprocessandexpansionof urban area, these WWTPs are increasingly surrounded by residential areas.


- 12 -

Therefore, it’snecessary toadoptmeasures toreduce theirenvironmental impacts, inparticularcontrolofodornuisance.

‐ Agedequipment.MostWWTPshaveoperatedformorethan10years,someevenmorethan 20 years, many facilities have been severely aged, and have resulted in higherenergyconsumption,lowerefficiencyandpoorreliability.

‐ Poordewateringefficiencyof sludge. The existingWWTPs basically employ directsludgethickening,andtheresultedsludgehashighwatercontent(average82%~85%).Thisbringsdifficultiesforsludgetransportanddisposal.

SludgeManagementPlanAccordingtothestatisticaldataprovidedbyGuilinDrainageCompany,thetotalquantityofsludge generated from existing WWTPs in 2012 is 157m3/d (82.6% water content). Inordertofindawaytodisposeofthesludge,Guilincityhasconstructedahigh‐temperatureaerobiccompositingsludgedisposalplantinsidetheexistingShangyaoWWTPinDecember2009.Thetreatmentcapacityis120m3/d(dewateredsludgewithwatercontentof80%).Aftercomposting, thesludgemeetsthenationalstandardsof landapplicationintermsofdrysludgecontent,healthandheavymetalindicators(theheavymetalcontentsofsludgeis alsowell below that of US federal standards for land application), and is used as soilconditionerinforestlandsandurbanlandscaping.The existing sludge treatment plant has a semi‐open design. Thismakes odor collection,water washing, and ion deodorization system ineffective and caused fairly seriousenvironmental impacts on ambient environment. It also occupies the reserved land ofShangyao WWTP, which prevents the future expansion of the WWTP to accommodateincreaseofsewage.Basedonstatistics,thetotalamountofsludgegeneratedfromexistingWWTPsinGuilinis122.75m3/d(82.6%watercontent). It isestimatedthatby2020,thetotalsludgeamountgenerated from WWTPs will be 175m3/d (80% water content). Therefore, Guilin isplanning to construct a new sludge management plant (with capacity of 130m3/dcomposting and 20m3/d solar drying). The specific location of the proposed sludgemanagementplantistobedeterminedduringtheprojectimplementationstage.Beforetheconstruction and operation the newly proposed sludge management plant, the existingsludgemanagementplantwithinShangyaoWWTPwillremainoperation.4.4 EnvironmentallyandSociallySensitiveReceptorsDuringEApreparation,detailedsurveyofenvironmentallyandsociallysensitivesiteswithinintheareaofinfluencehasbeenconductedthroughfieldinvestigationandconsultationwithlocalagenciesandcommunities.Itisconcludedthatthereisnospecialprotectedarea,ecologicalsensitivearea,naturalhabitatandphysicalcultureresourceswithintheareaofinfluenceoftheproposedproject.

The existingWWTPs are being operatedwith low efficiencyagedfacilities,andtheireffluentscannolongermeetthenewdischargestandardsrequiredby national regulations. The odor nuisance is becoming more and more serious publicconcernswith expansionof newurban residential areas around theWWTPs.The sludgedewatering facilities inexistingWWTPsare inefficient,andcurrentcompostingplanthassimple equipment with inadequate design and has serious impacts on ambientenvironment.Existingsewernetworkhasseriousleakageproblemsduetoagedpipelines,andcannotservethenewareasofurbanexpansion.Therefore,itisabsolutelynecessaryand timely to implement the proposed project, which will secure the water supply tosupport urban development, increase wastewater collection and treatment efficiency toprotectecologicalenvironment,especiallythewaterqualityofLijiangRiver.5.2 WaterSupplyComponentThemainalternativesconsideredforwatersupplycomponentarethechoiceofdisinfectionagent.Thecommonlyuseddisinfectantsincludeliquidchlorine,bleachingpowderandchlorinedioxide.Thecomparisonoftwodisinfectants,i.e.liquidchlorineandchlorinedioxide,isconsideredandshowninTable7.

In terms of the chemical absorption process, because its raw materials are NaOH and H2SO4, the dangerous goods warehouses that have high firefighting and explosion-proof requirements are needed, it is not suitable to be established in the existing WWTPs. The biological filtration process has a big footprint, with difficulties in operation and management and high operating costs. The liquid atomization and reactive oxygen ionization processes are suitable for deodorization of moderate- and low-concentration smelly gases and can overcome


- 17 -

the difficulties of the above processes well. However, the liquid atomization process needs to purchase working liquid regularly from a single procurement source, which is not good for operating management of the plant. In summary, the project intends to adopt the reactive oxygen ionization process for odor removal. 5.4 SludgeManagementComponentDisposalOptionsofTreatedSludgeFivesludgedisposaloptionswerecompared,including:directlandapplication;dewatering+landfill;incineration;useasconstructionmaterial;composting+landapplication.Prosandconsofthesefiveoptionswereconsidered,andatlast,thecomposting+landapplicationisconsideredasamaindisposalapproachgiventhecurrentsituationinGuilin,withconsiderationofincinerationasfutureoptionsandlandfilldisposalasanemergencybackupoption.Sludgecompostinghastheadvantageoflowcost,reducedvolumeandweight,reuseofnutrientsandmatureoperationalexperienceofexistingsludgeplantinGuilin.Thecompostedsludgemeetsvariousstandardsforlandapplication,i.e.theheavymetalcontentsofthetreatedsludgeiswellbelowthenationalstandards,aswellastheUSfederalstandardsforlandapplication.Therefore,itissafetoapplythecompostedsludgeinurbanlandscaping.However,withconcernsoflong‐termaccumulationimpactsofheavymetals,thetreatedsludgewillnotbeallowedforfertilizingfarmingcropsinanycase.Basedonthisconclusion,fourdetailedtechnicalschemeswereconsidered,including:(1) SludgefromWWTP(80%water)–compostinginsludgemanagementplant–land
