1. Manningham's WaterwaysManningham’s WaterwaysYarra River, WarrandyteManningham has an abundance ofnatural assets. These include anextensive waterway network that is avalued part of the local landscape.Identifying the environmental valuesand assessing the overall health ofour waterways is important if we areto effectively establish a long termvision and management strategy toprotect and sustain these livingsystems.Manningham’s waterways provide animportant habitat of natural andmodified bushland, open parkland andsemi-rural open space. Theselandscapes provide a wildlife corridorthat links the urban and peri-urbannatural environments.Manningham’s CatchmentsLocal creeks along with the YarraRiver provide a valuable aquaticecosystem for fish,macroinvertebrates, frogs and otheraquatic animals.Waterwatch 2013 Annual Report

The major water qualitythreats to Andersons Creek includesseptic and greywater discharge andsullage, stormwater pollution, landfilland contaminated sites, agriculturalrunoff, open space runoff andresidential development runoff.Andersons Creek discharges into theYarra River at Everard Drive,Warrandyte.Andersons Creek, Ringwood Warrandyte RoadJumping CreekJumping Creek is situated inManningham's Green Wedge. Muchof the creek’s riparian vegetation isstill intact and provides a significantwildlife corridor for a range of nativefauna and flora including platypus,fish and birds. The headwaters ofJumping Creek is located in the urbansuburbs of Warranwood and CroydonHills where urban constructedwetlands treat stormwater runoff. Themajor water quality threats toJumping Creek include stormwaterpollution, septic and greywaterdischarge and sullage, landfill andcontaminated sites, agricultural/horticultural runoff, open space runoffand residential development runoff.Jumping Creek, Warrandyte State ParkWaterwatch 2013 Annual Report 7

1. Manningham's WaterwaysMullum Mullum CreekMullum Mullum Creek runs through themiddle of the municipality andseparates the two distinct topographicand land use areas of Manningham. Tothe west of Mullum Mullum Creek arethe highly urbanised suburbs ofBulleen, Templestowe, Doncaster Eastand Donvale. To the east are the morePeri-urban suburbs of Park Orchards,Warrandyte and Wonga Park. TheMullum Mullum Creek Linear Park runsthe entire length of the creek andprovides a significant habitat andwildlife corridor. Threats to MullumMullum Creek water quality includestormwater pollution, septic andgreywater discharge and sullage,landfill and contaminated sites, openspace runoff and litter.Koonung CreekKoonung Creek runs along thesouthern border of the municipality.The creek has been significantlymodified or put underground during theconstruction of the Eastern Freeway.Water sensitive urban design wetlandshave been built alongside the freewayto protect the creek’s water quality andprovide a wildlife refuge. Theunderground section of creek runs forfour kilometres between DoncasterRoad and Thompsons Road and is animpenetrable barrier to aquatic wildlifebetween the Yarra River and theheadwaters of the creek. Threats toKoonung Creek water quality includestormwater pollution, open spacerunoff, residential development runoffand litter.Mullum Mullum Creek, Beckett RoadKoonung Creek, DoncasterWaterwatch 2013 Annual Report

2. Waterway EcologyUn-sewered ManninghamApproximately 4,620 properties inManningham are not connected to areticulated sewer. These propertiesutilise septic tanks and greywatersystems to treat domestic wastewater.Normally a septic tank treats anddisposes of all household wastewater,however, many unsewered propertiesin Manningham have a split greywater/septic system. These systemsdischarge untreated householdgreywater from the laundry, kitchen andbathrooms into the local stormwatersystem which then discharges thishighly polluted water directly into ourlocal creeks. Septic tanks that arepoorly maintained (if at all) result in thedischarge of effluent to localstormwater systems and waterways.Mullum Mullum Creek algae bloomUn-sewered Propertiesof ManninghamStormwater discharge, Ruffey CreekManningham SewerBacklog ProgramWater testing Mullum Mullum CreekMap shows locations to be sewered over the next decade.Waterwatch 2013 Annual Report

2. Waterway EcologyHard Surfaces and FloodingHeavy rainfall over a short time framecan cause significant and damagingstormwater surges. Reducing orslowing down these stormwater surgescan be a challenge. Household watertanks that collect rain water for onsiteuse is a great way to reduce this stormsurge. Engineering solutions caninclude raingardens, and waterretaining basins such as Ruffey Lakecan also slow surge events.Andersons Creek discharging turbidwater into the Yarra after heavy rainfallIn peri-urban environment good landmanagement practices and retention ofcatchment vegetation is extremelyimportant to the ecology of streams.Large areas of vegetation promotesseepage of rainfall into the substrateand reduces runoff during heavy rains.Streamside vegetation also plays animportant role by filtering outsuspended sediments and absorbspollutants from runoff water. It alsohelps hold the soil profile together andHarris Gully Tributary in floodreduce creek and river erosion.Andersons Creek flash flood at Everard DriveWaterwatch 2013 Annual Report 134

3. Sewer Backlog ProgramManningham Sewer Backlog Program—TemplestoweOver the coming years Yarra ValleyWater will be constructing a newsewerage system to previouslyunsewered parts of Manningham aspart of the Manningham SewerageBacklog Program.in Templestowe is now complete andhas been made available forhouseholders to connect. It is hopedthat most if not all properties in thisarea will be connected to the newsewer in 2012/13.Kestrel Creek is rated as highlydegraded and receives householdwastewater from the northern andcentral Templestowe areas.The program will provide a sewerageservice to properties with wastewatertreatment systems including septictanks, small treatment plants, andbiological or trickling filters.As discussed in this report the maincause of waterway pollution inManningham is the discharge ofhousehold wastewater into the localcreeks via the stormwater system.Construction of the new sewer systemHousehold wastewater fromunsewered properties in Templestowecan impact either Ruffey or Kestrelcreeks.Highly polluted stormwater dischargesare found in Ruffey Creek betweenKing Street and Dellfield Drive. Thedramatic deterioration in the waterquality of this section of creek is mostlikely from household wastewater fromunsewered properties in Templestowe.Waterwatch 2013 Annual Report

3. Sewer Backlog ProgramManningham Sewer Backlog Program—DonvaleThe majority of properties in Donvaleare currently unsewered, and arescheduled to be sewered under theBacklog Sewerage Program between2014—2016.The Donvale area is bound byGlenvale Road to the east, Mullumcreek and Smedley Road to the North,the East Link Tunnel to the south andOld Warrandyte Road to the west.The Donvale Sewer Backlog area islocated in the Mullum Mullum Creekcatchment. Waterwatch monitoringhas establish that the water quality ofMullum Mullum Creek in this areadeteriorates rapidly between Beckettand Tindals roads.This rapid deterioration in creek waterquality is caused by highly pollutedstormwater drain discharge atTandarook Crescent, Heads Road,Park Road and Conos Court.Stormwater discharges from thesedrains are observed to be of unusualcolour, odour and can have a foamy,soapy and/or oily consistency. Dryweather discharges, where the drainflows even if it has not rained for atleast 72 hours of rainfall, are alsoobserved.Water monitoring results indicate thathousehold wastewater is the likelysource of the stormwater pollutiondischarge.74Waterwatch 2013 Annual Report 2 15

3. Sewer Backlog ProgramManningham Sewer Backlog Program—Park OrchardsThe Park Orchards sewerage backlogarea contains properties that vary insize and wastewater treatmentsystems. There are approximately1,312 properties in this study area.The use of spilt systems in ParkOrchards that only treat toilet waste,with all other household wastewater(greywater) discharged off-site to thestormwater system without priortreatment, is prevalent.Systems designed to contain allwastewater on-site also exist, althoughmany have been found to notfunctioning properly. This is oftenbecause absorption trenches are notoperating effectively.Yarra Valley Water is currentlyassessing options to determine thebest method to service the ParkOrchards area.A piped sewerage network is usuallythe most common type of seweragesystem provided, however in ParkOrchards there is an innovative optionthat is being investigated that mayinvolve upgrading existing onsite septicsystems to a more modern standards.Waterwatch monitoring of the ParkOrchards area indicates that highlypolluted stormwater is impacting boththe Mullum Mullum and Andersonscreeks.Stormwater discharges are observedto have a distinct sewerage odour,have visible evidence of sanitary wasteand are soapy and oily in consistency.There is also stormwater dischargewhen no rainfall has occurred for 72hours or more when the stormwaterdrainage system should be dry.Park Orchards Sewer Backlog ProgramWaterwatch 2013 Annual Report

5. Waterwatch ResultsInterpretation GuideThis report gives a summary of thewater quality condition ofManningham’s municipal waterways.The report rates current waterway andcatchment condition from datacollected over a six year period (May2007—December 2012) using an A-to-F scale from the well establishedAustralian and New ZealandEnvironment and Conservation Council(ANZECC) fresh water guidelines.These guidelines provide anauthoritative guide for setting waterquality objectives required to sustaincurrent, and future, environmentalvalues.These guidelines provide governmentand the general community with asound set of tools for assessing andmanaging ambient water quality innatural and semi-natural waterresources. The strategy is based onthe philosophy of EcologicallyDamselfly from Koonung CreekSustainable Development (ESD). Theguidelines are used as a resource inorder to guide the ecologicalprocesses, on which life depends andis maintained.The 2013 Waterwatch Annual Reportuses the ANZECC guidelines to rateturbidity, electrical conductivity, pH andortho phosphorus at a site and subcatchmentscale using a score systemrated from ‘A’ (best quality) down to‘F’ (most degraded). The reportcompares the yearly results in order toassess water quality trends at both asite and catchment scale.Platypus in Mullum Mullum CreekMullum Mullum Creek at Beckett RoadWaterwatch 2013 Annual Report
