Grey iWater iManagement ifor iWater iManagement
Introduction i
All ihousehold iwastewater, iexcept itoilet iwaste, iis icalled igreywater. iThis iincludes iwater ifrom ishowering, ibathing, iand iwashing idishes iand iclothes. iThe iamount iof igreywater ivaries ienormously ibetween ihouseholds. i
Consumption iin ipoor iareas ican ibe ias ilow ias i15-20 ilitres iper iperson iper iday, iand iin irich iareas ipeople imay igenerate imore ithan iten itimes ias imuch. iIn iecological isanitation, igreywater iis isource iseparated ifrom itoilet isystems, iallowing ifor isimpler itreatment isystems ithan iconventional isewage itreatment iplants. i
Successful imanagement iof igreywater iincludes iboth itechnical imethods iand iuser iparticipation iin irunning iand imaintaining ithe isystem. iAll iparts iof ithe isystem, ifrom ithe ipoint iof iorigin ito ithe ifinal idischarge, ishould ibe iconsidered iwhen iplanning.
Composition iof igreywater i
The icomposition iof igreywater ivaries igreatly, ireflecting ithe ilifestyle iof ithe iresidents iand ithe ichoice iof ihousehold ichemicals ifor ilaundry, ibathing, ietc. iGreywater itypically icontains ihigh iconcentrations iof ieasily idegradable iorganic imaterial, isuch ias ifat iand ioil ifrom icooking, iand itensides iand iother iresidues ifrom isoap iand iother idetergents.
Pathogens iessentially ionly iexist iin ithe igreywater ifraction iif icontaminated iby ifaeces. iStill, ithe igreywater ienvironment iis ifavourable ifor ibacterial igrowth iwhich imeans ithat iit ineeds ito ibe itreated ibefore ireuse. iFurthermore, iuntreated igreywater ieasily iturns ianaerobic i(its ioxygen iis idepleted) iand ithus icreates ifoul iodours.
iNutrients iin igreywater i
The inutrient icontent iin igreywater iis igenerally ilow icompared ito inormal imixed iwastewater i(sewage). iIn isome icases, ithere ican ibe ihigh iconcentrations iof iphosphorus i(P), ibut ithe ilevels iof initrogen iare ialways ilow. iThe iP-content icould ibe ireduced ito ilevels ilower ithan inormally ifound iin iadvanced itreated iwaste iwater iif ipeople iused ionly iP-free idetergents, ithus iminimizing ithis istep iin ithe iprocessing ibefore ireuse.
Source icontrol i
Preventing ithe ineed ifor itreatment ishould ibe iseen ias ia ivital ipart iin iall igreywater imanagement. iThis ican ibe idone iby icontrolling ithe ipollution iload iand ithe iamount iof iwater iused. iTherefore, iit iis iessential ithat iall igreywater isystems iinclude iinformation ifor ithe iusers iregarding ienvironment-friendly ihousehold ichemicals iand iwater-conserving itechniques. iBy icombining iwater-saving iequipment iwith ieconomical iincentives, isuch ias ia ifee isystem ifor iwater iconsumed, igreywater iproduction ican ibe ireduced isignificantly.
When iplanning ifor iu
an isanitation, ithe iaim ishould ibe ifor ievery iperson ito iproduce iless ithan i80 ilitres iof igreywater iper iday.
Fig i. i1 iGrey iWater iTreatment
Objectives iof iGreywater iManagement
• iTo iavoid idamage ito ibuildings iand isu
ounding iareas ifrom iinundation, iwaterlogging iand ifreezing.
• iTo iavoid ithe icreation iof ibad iodours, istagnant iwater iand i
eeding isites ifor imosquitoes. i
• iTo iprevent ieutrophication iof isurface iwaters. i
• iTo iprevent icontamination iof igroundwater iand idrinking iwater ireservoirs. i
• iTo iuse igreywater ias ia iresource ifor ilandscaping, iplant igrowth, iand igroundwater ireclamation.
Setting iup ia isystem
A ipipe isystem iis ineeded ifor icollection iand itransportation iof ithe igreywater. iThe idifference ifrom ia itraditional imixed iwastewater isystem iis ithat ithinner ipipes ican ibe iused isince ithere iis ino ineed ito itransport itoilet iwaste. iTo iprevent iclogging ifrom igrease, ithe ipipes ishould ibe iinstalled istraight i(no inecks ior idepressions) iwith ia igradient iof iat ileast i0.5%. iIn ismaller isystems, igreywater ican ioften ibe iled idirectly ito ia imulch ibed iwhere ithe iwater iis iused ifor igrowing iplants ior itrees. iThe idesign iand idimensions iof ithe isystems ineeds ito iallow ifor ithe iwater ito ibe iassimilated iby ithe isoil-ecosystem.
For ilarger isystems iwhere ithe iwater imay ibe istored ifor ilong iperiods, ia ineed ifor ipre-treatment iarises. iSuspended isolids i(SS) ineed ito ibe iremoved ibecause ithey imay iclog ithe isystem ior icreate ibad iodours. iThe iSS-particles ican ibe iremoved imechanically iby igravity, ias iin ia iseptic itank isystem, iby iscreens ior ifilters ion iprefa
icated iequipment ior ias icheaper igravel ifilters ifor ithe ismaller iscale.
Greywater iapplication
It iis iimportant ithat ithe iwater iis ispread ievenly ion ithe isurface iof ithe ifilter. iUneven idistribution icauses ideep iclogging izones iwhere ilittle ior ino itreatment ican ioccur, iwhile ithe imain ipart iof ithe ifilter iis ileft iunused. iIn ithe iworst icase, ithe iwater iwill iflow ithrough ithe ideep ipores idirectly ito ithe igroundwater iwith ilittle ior ino ipollutant iremoval. iThe iuse iof i‘controlled iclogging’ iin igravity isystems ican ihelp iovercome ithe iproblem. iThis ican ibe iachieved iif iwater iis iapplied iin ia ina
ow itrench iwhere ithe ibottom iis iallowed ito ibe iclogged iwith ibiofilm. iWater iwill iimpound, ispread ihorizontally iand iinfiltrate ithrough ithe iwalls iof ithe itrench. iBacteria icommunities iin ithe iinterface ibetween iwater iand isoil iwill ihelp idecompose iorganic ipollutants.
Other idistribution ioptions ifor isoil ifilters iinclude:
Surface iflooding. iHigh iamount iof iwater iis iapplied iin ia ishort itime i(5 icm icolumn iin i5 iminutes), ito iallow ifor ieven iinfiltration. i
Perforated ihorizontal ipipes. iPlastic ipipes iwith idrilled iholes. iWater ican ibe iadded iin ismall idoses. iThis isystem iis isimple ito iconstruct iand imaintain. i
Drip ii
