1 EMAS Water Systems Author: Wolfgang Eloy Buchner (*) (*) German promoter of improved rural water supply and sanitation, working in Bolivia.

2 EMAS Escuela Móvil de Agua y Saneamiento (Mobile School for Water and Sanitation) Established in Bolivia since 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.

3 EMAS 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 Technology

4 The EMAS pump Components of the pump Glass marble valves Self-construction in Nicaragua

5 Final Products EMAS Handpump, installed in a thin (1.5) manually drilled borehole. Simple washing basin with faucet, shower cell, and their water deposit, filled with the pump, on top.

6 EMAS Rainwater Harvesting Horizontal underground rainwater tank (6,000 litres) Large superficial tank of ferro-cement (8 m3) Fast filter

7 Some other EMAS alternatives Dry letrine Water filter Narural well captation

8 Simple and cheap technology, but ROBUST! (3 persons plus a 120 kg water tank on top of the shower cell without frame)
