Latrine Design and Construction Workshop

Published in: 2014


This collection contains the resources for both trainers and participants for the Latrine Design and Construction workshop. This five-day workshop is designed for latrine project implementers and masons. In this workshop, participants will learn how to design and construct latrines for low-income communities not connected to a sewerage system. The focus is on designing latrines that are technically and environmentally appropriate, and that people will actually want and use.

Content - Summary

Upon completion of the workshop, participants will be able to:

• Discuss local and global issues and how sanitation is connected to the poverty cycle
• Identify pathogens related to sanitation and explain how to prevent disease transmission
• Discuss the five components of a sanitation system to properly manage human excreta
• Identify the parts of a latrine and describe their function
• Identify technology options for each latrine part and describe their basic design, advantages, and limitations
• Explain user-focused design and how it can be used to design latrines that people want and will use consistently and sustainably
• Calculate the required size of latrine pit
• Explain how to excavate and line a latrine pit
• Construct some basic latrine components, such as a slab, superstructure or pit lining
• Explain the factors to consider when siting a latrine
• Discuss different options to manage full latrines
• Describe how latrine sludge can be safely treated and used or disposed of
• Discuss the importance of handwashing with soap, describe the critical times and procedure for proper handwashing, and discuss the need for handwashing hardware and software
• Discuss latrine options for challenging environments such as areas with high groundwater, flooding, high population density, cold climates or fragile ecosystems
• Identify the materials required and basic costs to build a latrine
• Discuss the purpose of the project framework and describe the five components needed for a successful and sustainable sanitation project
• Establish a network of contacts with other project implementers

The following is a tentative list of the topics covered in the workshop. A specific agenda will be developed based on consultations with the organizer and participants. In general, one to two practical construction sessions listed below will be selected for each workshop.

• Local and global sanitation issues
• Pathogens and transmission of sanitation-related diseases
• Sanitation systems for managing human excreta

• Selecting latrine technologies
• Designing latrine slabs
• Sizing, excavating and lining pits
• Siting latrines
• Emptying latrines and transporting sludge
• Treating, using and disposing sludge
• Handwashing with soap
• Estimating costs of building a latrine
• Introduction to the project framework

• Constructing latrine slabs
• Constructing a superstructure
• Constructing a toilet seat and pedestal
• Designing and sizing a latrine pit
• Excavating and lining a latrine pit
• Constructing a handwashing station
• Latrine design scenario exercises
• Next steps in project planning
