As part of a previous project, a series of pico hydro newsletters were produced - in total 9 issues between 1997 and 2001. It is planned to scan these and put them on the web site. We have a few printed copies left which we may be able to send to organizations in developing countries. Please email us if you wish to enquire.
Case Studies : Nepal & Kenya
Nepal Case Study - Details of the design, implementation and lessons learnt from a 4kW pico hydro scheme, in 4 parts:
The Kenyan schemes at Kathamba and Thima were recongized as examples of good practice in sustainable technology by the Ashden Awards in 2004. There is also a paper published about these schemes in the Journal of Renewable Energy.
Kenya Case Study 1 - Design and implementation of a 1.1 kW pico hydro serving 65 households.
Kenya Case Study 2 - Design and implementatoin of a 2.2 kW pico hydro serving 110 households.
Propeller Turbine Design Guide - this describes how to design a pico turbine suitable for 2 - 10 m heads. This design guide is to be used alongside the calculation spreadsheets listed below. It is intended to be used by turbine design engineers and small manufacturers all over the world who want a low head turbine design suitable for rural electrification.
Low Head Design Spreadsheet (overall design spreadsheet)
Coefficients (gives lift and drag coefficients for constant thickness blades)
Water Power for a Village Business - Initial Advice and Ideas to Help You Explore Opportunities for Harnessing Power from Streams and Rivers. This booklet by Adam Harvey and Nigel Smith is in three parts:
Pico Hydro for Village Power - A Practical Design and Installation Manual for Schemes up to 5kW in Hilly and Mountainous Areas. This manual, by Phil Maher and Nigel Smith, is in seven sections so that the files are smaller for downloading. There is also a version in Spanish.
