- 1. Water Treatment &Recycling Solutions Reduce, Reuse & Recycle
- 2. WATER : Whatis the issue? • Economic growth : without corresponding infrastructure • Urbanization – Increasing density of population in cities/towns – apartments/commercial buildings – Expanding peripheral areas : – Chennai: OMR, Oragadam, GST – Gurgaon / NCR – Hyderabad – Gachibowli, Miyapur, Uppal,Patancheru • Huge increase in water consumption Where is the water coming from ? – Rivers, Lakes, Ponds …..and now, mainly Ground water!
- 3. WATER : Nextissue! • Sources of water drying up • A larger issue coming up – – Contamination of Water Sources • The way we dispose off waste water is the biggest issue in water management!
- 4. 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 water and waste in its last chapter “The agenda for water to water”.

- 5. Recognize and manageSewage • Recognize and manage Sewage : 78 % officially not treated and let out 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 - the dangers : Spread of disease, contamination of soil and pollution of ground water • Quote from Report : “Sewage must be our obsession” • Quote : “Mantra is Decentralization”
- 6. What is “Decentralized”sewage treatment? • Current system : sewage is the responsibility of the Government / public authorities • But – how can public authorities manage? : – 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, Local Treatment – “Dencentralized” STP
- 7. Why Decentralized ?Local benefits! • On-site treatment and discharge – Reduces load on existing sewage system – Local treatment and discharge – protects contamination of water sources (rivers, water bodies, ground water) • Domestic Water consumption : Over 30 % for flushing, washing facilities etc – NON CONTACT applications – Suitable for RECYCLED water
