Introduction

Dealing with liquid wastes is one of the biggest challenges of urban sanitation. Liquid waste management requires capital investment, skilled personnel, coordination between different government departments and organisations, and awareness of the issues by the public. Failure to manage liquid wastes, especially human excreta, leads to health and environmental problems. Different sanitation technologies require different techniques for managing and disposing of the wastes.

This study session looks at what happens to human excreta and other liquid wastes after they are produced. You will learn about the methods used to remove sludge from pits and septic tanks and about some of the options for managing and treating liquid wastes, including human excreta, sullage and stormwater.
