New concepts for on-site sanitation based on bio-additives and pit design

2011 - 2016 • London School of Hygiene and Tropical Medicine (LSHTM)

Purpose

The project assesses the potential of modern biotechnology to deliver effective bio-additives which can accelerate decomposition processes and extend the lifetime of pit latrines.

Activities

The project assesses the potential of modern biotechnology to deliver effective bio-additives which can accelerate decomposition processes and extend the lifetime of pit latrines. It will also build a sound scientific understanding of the key factors influencing decomposition processes, including the potential of pit design to improve fill rates and longevity. At the same time, research will be undertaken to build a deeper understanding of the current user experience, needs and aspirations of on-site sanitation that can be used to inspire improved, lower cost on-site sanitation options for the poor.

Detailed location of main activity  Countries of activity

Objectives

To identify scientific advances from a variety of fields that could improve pit latrine performance, for example by accelerating faeces decomposition, or decontaminating faeces

To understand decomposition processes and the influence of on-site sanitation design factors on performance to support bio-additive and/or pit latrine product development.

To assess the current/potential market and understand consumer needs/aspirations for on-site sanitation, so any new products/designs will be adopted and used

To generate new on-site sanitation concepts for further development and commercialization, that may lead to a step change in performance, cost-effectiveness, and user adoption, use and maintenance of on-site sanitation (workstreams 5 and 6)

To create a platform for future research and development based on key insights and potential partnerships to further accelerate improved on-site sanitation for the poor.

Stockholm World Water Week 2018!

World Water Week is organised by the Stockholm International Water Institute (SIWI) and takes place in Stockholm, Sweden. It has been the annual focal point for the globe’s water issues since 1991. Individuals from around the globe also present their findings at the scientific workshops.

Projects

The project database contains nearly 400 sanitation projects of many different organizations dealing with research, implementation, advocacy, capacity development etc. Advanced filtering functions and a global map are also available. Information on how and why this database was created is here.

People working for SuSanA partners can add their own projects through their partner profile page. You might need your SuSanA login upgraded for this purpose. Please contact us if you would like to add a project.
