Water Treatment & RecyclingSolutionsReduce, Reuse & Recycle
WATER : What is the issue?• Economic growth : withoutcorresponding infrastructure• Urbanization– Increasing density of population incities/towns –apartments/commercial buildings– Expanding peripheral areas :– Chennai: OMR, Oragadam, GST– Gurgaon / NCR– Hyderabad – Gachibowli, Miyapur,Uppal,Patancheru• Huge increase in water consumptionWhere is the water coming from ?– Rivers, Lakes, Ponds …..and now,mainly Ground water!
WATER : Next issue!• Sources of water drying up• A larger issue coming up –– Contamination of Water Sources• The way we dispose offwaste water is thebiggest issue in watermanagement!
Report Summary• Citizens’ Seventh Report on the State of India’s Environment,“Excreta Matters: How urban India is soaking up water,polluting rivers and drowning in its own excreta”– by Centre for Science and Environment, New Delhi• Report released in May 2012 – covering 71 cities of India,research over 3 ½ years• The report spells out a six-fold strategy for managing waterand waste in its last chapter“The agenda for water to water”.Source : http://www.indiawaterportal.org/post/26422and http://cseindia.org/userfiles/excreta-matter.pdf
Recognize and manage Sewage• Recognize and manage Sewage :78 % officially not treated and letout into rivers, lakes, ground– Sewage generated = 38,255 mld– Capacity to treat = 11,788 mld (30%)– Sewage actually treated = 8,251 mld(22%)• Improper Sewage disposal - thedangers : Spread of disease,contamination of soil and pollutionof ground water• Quote from Report :“Sewage must be our obsession”• Quote :“Mantra is Decentralization”
What is “Decentralized” sewage treatment?• Current system : sewage is theresponsibility of theGovernment / public authorities• But – how can public authoritiesmanage? :– Cost and challenge of connecting :widely spread out “development”,apart from untenable logistics –expensive to connect– Land availability – for “centralized”treatment plants?!• Hence -> On-site, LocalTreatment – “Dencentralized” STP
Why Decentralized ? Local benefits!• On-site treatment anddischarge– Reduces load on existingsewage system– Local treatment and discharge –protects contamination ofwater sources (rivers, waterbodies, ground water)• Domestic Water consumption: Over 30 % for flushing,washing facilities etc – NONCONTACT applications– Suitable for RECYCLED water
