Urban local initiatives and government responses A case of Dev Nadi in Pune
Posted on 22 Nov, 2014 10:30 AM

Most of the rivers and streams in urban India are dead. With a very few and rare exceptions, these once-beautiful water bodies have been encroached upon, sources dried up or converted into sewage drains all over the country.Water is being sourced or pumped from sites upstream of the city for its needs or from long distances and the city administration has little incentive for cleaning its own muck. The dismal figures of urban sewage treated by sewage treatment plants, their installed capacity and efficiency stand testimony to this.

Successful innovations in solid waste management systems Examples from five local bodies in Tamil Nadu
Posted on 22 Nov, 2014 10:30 AM

Innovations in Solid Waste Management Systems - Tamil NaduThis booklet about the work of Exnora Green Pammal (EGP), produced by UNICEF and published by the Government of Tamil Nadu,  illustrates examples of the implementation and impact of solid waste management innovations in five localities in Tamil Nadu. The solid waste management systems in these localities are widely regarded as successes that deserve replication.This document has been produced to inspire and enable more local body authorities to emulate such successes in other parts of the country.

Improving solid waste management services in India is an urgent challenge for all levels of the government. Littering and the indiscriminate disposal of solid waste are widely practiced, polluting India's air, water, soil and inhabitants. Such pollution impedes India's efforts to achieve the Millennium Development Goals (MDG).The nation's measures to combat malaria and other diseases (MDG 6), reduce child mortality (MDG 4), and ensure environmental sustainability (MDG 7) are all hampered by the unsightly and unhygienic conditions created by the accumulation of waste.{C}

Manual on sewage and sewerage treatment CPHEEO MoUD
Posted on 22 Nov, 2014 10:30 AM

This manual has been prepared by the Central Public Health and Environmental Engineering Organisation (CPHEEO), a department under the Ministry of Urban Development (MoUD) and aims at meeting the professional needs of practising engineers dealing with the sanitation sector in the country, that focuses on achieving the goal of 'sanitation for all' within a reasonable timeframe.

The manual  is a revised version of the earlier one, which was developed in 1977 and was widely used by field engineers engaged in sewerage and sewage treatment. However, a need was felt to revise and update the earlier manual taking into consideration the advancement in technology.
