The urban affordable clean Toilets (U-ACT) project, headed by the Centre for Development and Cooperation (NADEL) of the Swiss Federal Institute of Technology (ETHZ), aims at overcoming the constraints to private sanitation investment in poor urban areas. Field research was conducted in 40 randomly selected low-income areas of Ugandas capital Kampala where people rely on on-site sanitation. The sanitation situation in these urban slum zones is characterised by a high number of users per toilet, and full or overflowing latrines that are not regularly emptied. The U-ACT project activities include the construction of ventilated improved pit (VIP) latrines. This factsheet provides information on the construction and cost details.

The addition of a vent pipe to a simple pit latrine is one way of reducing the nuisance of flies in the cubicle if the cubicle is kept clean and dark. This type of latrine is called a ventilated improved pit (VIP) latrine. VIP latrines effectively control odour and flies while still allowing users to clean themselves with hard materials such as newspaper and leaves which may not suitable for use with a pour-flush latrine. A squatting plate or a pedestal can be installed. There are a number of designs to suit different situations but they all work in much the same way. This guide describes how they work and presents various designs and design details.
