EMAS Water Systems Author: Wolfgang Eloy Buchner (*) (*) German promoter of improved rural water supply and sanitation, working in Bolivia.
EMAS “Escuela Móvil de Agua y Saneamiento” (Mobile School for Water and Sanitation) • Established in Bolivia since 1990. • Promoted drilling of > 20,000 wells and > 50,000 water systems within the reach of the most disadvantaged rural populations in the developing world. • Construction by the users themselves. • EMAS handpump technology patented for the benefit of Humanity. • Provides water supply solutions for any place inhabited by humans.
EMAS The Technology • Manual drilling of wells up to 100 m deep at a cost of 6-8 US$/m. • Construction of handpumps by the users themselves with cheap materials (aprox. US$ 6 plus US$ 1 /meter water depth) and available from any hardware store. • Self-construction of small water storage tanks and distribution systems, complete with wash basins and simple showers. • Self-construction of rainwater harvesting systems, with storage tanks up to 8,000 liters each, featuring different models in accordance with local conditions (one bag of cement per 1,000 litres capacity). • Self-construction of small irrigation systems for household gardens. • Water filters, solar water heaters, dry letrines etc.
The EMAS pump Components of the pump Glass marble valves Self-construction in Nicaragua
Final Products Simple washing basin with faucet, shower cell, and their water deposit, filled with the pump, on top. EMAS Handpump, installed in a thin (1.5”) manually drilled borehole.
EMAS Rainwater Harvesting Horizontal underground rainwater tank (6,000 litres) Fast filter Large superficial tank of ferro-cement (8 m3)
Some other EMAS alternatives Water filter Narural well captation Dry letrine
Simple and cheap technology, butROBUST! (3 persons plus a 120 kg water tank on top of the shower cell without frame)
