Ventilated Improved Pit (VIP) toilet systems installed in South Africa are constructedaccording to a wide variety of designs and with many different types of materials, with a correspondingdiversity of pertormance level and user acceptability. Some designs are of a good standard, but manytoilets have been installed which do not function properly and are therefore unpleasant to use. Flycontrol is often inadequate and factors such as poor construction , high temperatures and bad odourscan contribute to negative user experience and subsequent perceptions of the systems as second-rateor is generally accepted that the government cannot afford to provide conventional waterborne sanitationto all communities lacking this facility, at least for the foreseeable future.
