Design of a Low-Cost Bamboo Well

Bamboo wells are an economical alternative for water supply wells in developing countries. The design of the bamboo well described in this article was developed based on field tests. Following field experiments, the screen in the bamboo well was fabricated with seven 3-m-long bamboo strips, each 2 cm wide and 1 cm thick. The strips were bolted on 1-cm-wide mild steel rings spaced 30 cm along the length of the bamboo strips, with 9-cm-long galvanized iron pipe end pieces. Pipes used in the bamboo well were fabricated by wrapping polythene sheets on the bamboo screens. Excellent performance, low cost, and good service life justify the use of a bamboo well for ground water withdrawal in developing countries.
