During emergencies in urban settings when space is limited for sanitation and the use of facilities is high, latrines fill-up quickly. WASTE, LSHTM and their partners aim to improve access to a safe sanitation system by:
Emergencies vary widely from the urban to refugee camp settings. During emergencies in urban areas when the sewer system is damaged the typical solutions may be household level containers (bags, buckets), however once the containers are full usually they are collected and disposed of in the environment without an appropriate treatment, causing pollution and transmitting diseases to the population.
The proposed innovations would identify products (bio/chemical-additives) to facilitate quick and safe disposal of faecal matter and/or reduce the fill-up rate of the container, therefore extending its life.
The project involves two innovative solutions to guarantee the access to a sanitation system during emergencies:
The first innovation aims to sanitise and stabilise faecal matter by: defining the product (bio-additive) requirements in emergency situations; inventorying and short-listing existing bio-additives, and proofing the most promising solutions on real faecal matter.
The second innovation aims to develop a bio-additive that can promote rapid decomposition of faecal matter by: identifying pit’s characteristics to quick decomposition, identifying 100 latrines that never fill-up and sampling and analysing the contents of selected latrines.
