Abstract

Access to proper sanitation is a basic step towards sustainable development, and crucial to the health of any community. 2.6 billion people in the world lack access to any excreta disposal facility (UNICEF, 2005), with only 29% of the rural population of South Asia having sanitation coverage (WHO/UNICEF, 2000). As people living in the rural Devikulam the state of Tamil Nady need assistance in the implementation of several compost toilet projects. Due to the high water table and copious amount of rainfall found in many coastal areas, standard pit latrines may not be a feasible technology for sanitation problems in the developing world. Because the compost latrine described in this report is constructed above ground with a concrete base, it is feasible for any waterlogged or high-water-table area. This report provides the development worker, who believes compost latrines can be a solution to sanitation problems, with knowledge to successfully implement a compost latrine project.

Introduction

The team, since its formation, has been introducing different approaches to find better solutions for the problems exist in Devikulam Village. Every approach has been documented and introduce in this report. The report aims to give you an overview of what you need to know about Devikulam, from different aspects. In addition, addressing the problems that the village having, takes a lot of attention in this report. The way the team has thought of these problems, also explained in details.

The first part of this report will be concerned about the general information of Devikhulam village, background, past projects, team ethics, concepts and causes of problems all these topics will be included in this report to give the reader a comprehensive knowledge of the village. The Second part of this report will introduce variety of concepts that the team has thought of, before finalizing its concept.

A composting toilet is a predominantly aerobic processing system that treats excreta, typically with no water or small volumes of flush water, via composting or managed aerobic decomposition. This is usually a faster process than the anaerobic decomposition at work in most wastewater systems, such as septic systems. Composting toilets are often used as an alternative to central wastewater treatment plants (sewers) or septic systems. Typically they are chosen (1) to alleviate the need for water to flush toilets, (2) to avoid discharging nutrients and/or potential pathogens into environmentally sensitive areas, or (3) to capture nutrients in human excreta. Several manufactured composting toilet models are on the market, and construct-it-yourself systems are also popular.

These should not be confused with pit latrines (see latrine, pit latrine, and arborloo or tree bog), all of which are forms of less controlled decomposition, and may not protect ground water from nutrient or pathogen contamination or provide optimal nutrient recycling.
