Zimbabwe: The clean and revolutionary VIP latrine explained by its inventor

The odourless and hygienic Ventilated Improved Pit latrine has improved the lives of tens of millions of Africans. In this episode, Dr Peter Morgan – a pioneer in the water, sanitation and hygiene sector for the last four decades – describes how he designed this toilet and how it was rolled out in his adopted country Zimbabwe. He also describes his other innovations, including using human waste as compost at a primary school – the subject of a recent presentation at the Water, Engineering and Development Centre conference at Loughborough University.
