1. INTRODUCTION

Water is considered very precious and needs to be used wisely, especially as its availability is becoming limited. A major source of water loss in household chores is the washbasin,alsoknownasgreywater.Therearesignificant prospects for sustainable reuse on academic campuses, wherewaterisusedextensivelyforhandwashingandother water-intensive tasks. This project focuses on conserving water, creating an eco-friendly campus environment, and recyclingwashbasinwastewaterforgardening.Theproject involvescollectingwastewater,purifyingit,andusingitto irrigate campus gardens.

3.1 Study Area:

Forthisstudy,theresearchiscurrentlyexamininggreywater atJSPM'sRajarshiShahuCollegeofEngineering,locatedin Tathawade,withintheurbanizingPimpri-Chinchwadareaof the Pune district, Maharashtra, India. The college is approximately located at 18°37'14.2"N 73°44'54.9"E. The collegecampusiscurrentlyprovidingamicrocosmoftypical water consumption patterns found in residential and institutional settings.

3.2 Sampling technique:

Sampling is currently considered a critical process in research,especiallywhenresearchersaredealingwithlarge populations or continuous flows like wastewater. This processinvolvestheselectionofarepresentativesubsetof the whole for analysis, ensuring that the results are being indicativeoftheoverallcharacteristics.Thegoaliscurrently beingfocusedonobtainingsamplesthatminimizebiasand areaccuratelyreflectingthepropertiesofthesource.

Inthisresearch,the'BucketMethod'isbeingemployedasa formofdirect,orgrabsampling,specificallybeingadapted for collecting greywater from washbasins in college washrooms. Direct collection is occurring by directly capturing greywater as it is flowing from the washbasin outlet, which is considered a simple and cost-effective approachthatisparticularlysuitableforsmall-scalestudies and situations where sophisticated sampling equipment is not being made available. A 20–30-liter capacity bucket is beingusedastheprimarycollectionvessel,whichprovidesa practicalsizeforcapturingasufficientvolumeofgreywater withinareasonabletimeframe.Ascreenisbeingplacedatthe pipe inlet to filter out larger solid particles from the greywater,whichpreventscloggingandremovingdebristhat isinterferingwithsubsequentanalyses.Thismethodisbeing tailoredtothespecificcontextofcollectinggreywaterfrom college washbasins, which offers a practical solution for capturinggreywaterfromaknownandrelativelyconsistent source.

4.4 Methods for Evaluation:

The present study utilized three methods, which are discussedindetailbelow:

1) General Water Requirements (Typical Values): [12]

Lawns: Lawns require about 25-30 mm of water per day (this can vary based on climate, plant type, and soil conditions).

ShrubsandOrnamentalPlants:Waterrequirementsvarybut canrangefrom5-10mmperday.

Trees:Trees,dependingontheirsize,mayrequireanywhere between25-50mmperday.

Assumingawaterdemandof50mmperday,

Totalwaterdemandbytrees =area×depthofwaterrequired×nooftress =225×50/1000×27 =305litres/day

Totalwaterdemandbyshrubsandornamentalplants=area ×depthofwaterrequired×noofplants =225×10/1000×320 =720litres/day

Totalwaterdemandbytreesandplantsinthestudyarea= 1025litres/day.

Assumingtotalloss(evaporation,runoff,deeppercolation) of50%,thentotaldemand=1025×1.5=1540litres/day.

2) Estimation Formula (Based on Evapotranspiration: [13]

Water Requirement (L/day) =Area (m²) ×ET (mm/day) ×1/1000×noofplants

Totalrequirementofwaterforgardening225m2

Water requirement for trees = 225×9×1/1000 ×27 =55 liters/day

Waterrequirementforshrubs=225×3×1/1000×320=220 liters/day

Totalwaterdemand=275liters/day

Assumingtotalloss(evaporation,runoff,deeppercolation) of50%,thentotaldemand=275×1.5=415liters/day

3) Using volume and area relation, assuming 5-10 liters/m2

Totalwaterdemand=area×waterrequirement =225×6 =1125liters/day

Assumingtotalloss(evaporation,runoff,deeppercolation) of50%,thentotaldemand=1125×1.5=1690liters/day

• Applications and reuse:

Treatedgreywater, while notsuitable forpotable use,can fulfil various non-potable water demands, including gardening,fountains,firefighting,andcarwashing,thereby significantly reducing freshwater consumption. This will leadtoamorebalancedsituation.Afterutilising1,690litres ofwaterforgardening,anadditional310litresofwatercan beusedtoirrigateanextra41m²ofgardeningorgreenarea.

• Water and Wastewater Implications of Greywater Reuse:

Implementing a wash basin wastewater reuse system on campuscansignificantlydecreasetheuniversity'sreliance on potable water for irrigation, potentially offsetting a substantial portion of current usage. Simultaneously, by treatingandreusingthiswastewateron-site,thevolumeof effluentdischargedtothe municipal sewersystem will be reduced,leadingtopotentialsavingsinsewagechargesand easing the load on Pune's wastewater treatment infrastructure.

5. RESULTS AND DISCUSSION

Thestudy'sfindingsareindicatingasubstantialvolumeof greywatergeneration,estimatedattwothousandlitresdaily, from wash basins at JSPM’s Rajarshi Shahu College of Engineering. This is representing a significant potential source of water being diverted for non-potable reuse, specifically for campus gardening.

Comparing daily greywater generation (2000 litres) with peak water demand (1690 litres) is indicating sufficient greywater availability for gardening. This finding is supportinggreywaterreuseasaviablestrategyforreducing freshwater consumption on campus. Yet, the pumping's operational cost is underscoring the need for system optimization to balance water conservation and costeffectiveness.

6. CONCLUSIONS

The analysis of washing basin wastewater reuse for gardeningatJSPM’sRajarshiShahuCollegeofEngineeringis confirmingits feasibilityandpotential benefits. The study findsthatwashbasinsaregeneratingasubstantialamount of water, approximately 2000 liters daily. This volume is proving sufficient to meet the highest estimated water demand for the 225 m² gardening area, which is being calculated to be 1690 liters per day using Method 3. By substituting freshwater with greywater, the system is significantly reducing potable water consumption, promotingsustainablewatermanagementoncampus. However, the results and discussion highlight a key challenge:theoperationalcostassociatedwithrunningthe waterpump,estimatedat₹7350permonth.Toaddressthis, thestudyisrecommendingimplementinganenergy-efficient pumping system and exploring improved filtration techniquestoenhancethelong-termeconomicfeasibilityof greywaterreuse.

Additionally, research could also involve investigatingthelong-termeffectsofgreywaterirrigationon soil properties and plant health, which would provide valuable insights.
