Good public information doesn't come easy these days and many utilize it for profit and often find a way to eliminate it from public eye. Quite often this happens with information published with public money funding academic studies for which industry later purchases the rights and patents. For this reason when we find good information we copy it and preserve it before it vanishes.
Sewage systems and clean water access has for centuries been the largest by far source of health improvement to urban populations. Medicine is quite overstated as a significant component of health, not coming even close to clean water and safe sewage systems, food, shelter, and working conditions.
Simplified Sewerage
This web site is aimed at giving support for the publication PC-Based Simplified Sewerage Design and it accompanying Windows based design program. Links are also given to publications on this and other low cost sewerage systems NOW AVAILABLE IN SPANISH AND IN PORTUGUESE AND IN FRENCH (as of 19 Jan 2011) see the download page
Introduction PC-Based Simplified Sewerage Design was published by the School of Civil Engineering, University of Leeds, UK, in January 2001. It is a manual and windows based design program for use in the design of the simplified sewerage system. It was published with the aim of promoting the use of simplified sewerage throughout the developing world. To quote the preface of the manual:
"Simplified sewerage is an important sanitation option in peri-urban areas of developing countries, especially as it is often the only technically feasible solution in these high-density areas. It is a sanitation technology widely known in Latin America, but it is much less well known in Africa and Asia. It is the purpose of this Manual to disseminate this technology more widely in the developing world, so that it can be used in peri-urban sanitation programmes and project to improve the health of poor communities. However, simplified sewerage is not just for peri-urban areas - it can be successfully and appropriately used in middle-and upper-income areas as well. We hope that this Manual serves its purpose of making simplified sewerage better known throughout the developing world, and that the PC-based design program contained herein facilitates the hydraulic design calculations."
How To Get The Manual and Program The manual and program are both available to be downloaded from this site.
- The manual in .pdf format can be viewed or downloaded here and
- Details of how to download the design program can be found here.

Note that there is a limited supply of printed manuals and CDs. Simplified Sewerage Description Simplified sewerage is an off-site sanitation technology that removes all wastewater from the household environment. Conceptually it is the same as conventional sewerage, but with conscious efforts made to eliminate unnecessarily conservative design features and to match design standards to the local situation.
