Information about water systems that require no pumps to make them work, using only the contours in the terrain to deliver clean drinking water.
Water will be in the twenty-first century what oil was in the twentieth century. Global fresh water shortages and drought conditions are spreading in both the developed and developing World.
This page is aimed at those who are working to confront this growing problem, providing low-fat manuals, high-fibre modelling software, easy-to-use spreadsheets and accessible technical data to assist in the design, construction, and maintenance of water supply systems. The page is divided into sections for quick access to the information required. All material is copy-left and can be freely reproduced and distributed, unless otherwise stated.

Water Filtration
Documents about slow sand filtration and multi-stage filtration. Slow sand filtration can be use from a very small household scale right up to filtering the water supplies for whole cities. It allows water to pass slowly through a sand bed where the majority of the purifying process happens in a naturally occurring bio-layer in the first few millimetres of [...]
