手工鑽井中的EMAS方法是融合了[[Jetting - general|水力噴射]]、[[Percussion - general|衝擊鑽法]]以及[[Sludging - Rota sludge|迴旋式]]之鑽井技術。此方法需使用手動泥泵，每個行程末端鑽桿皆轉90度；這可鑽鑿到各種鬆土、綜合材料及輕石。但鑽桿無法穿過硬原岩及卵礫石（如：地下的古老河床）。管井直徑一般為37毫米。
The EMAS drilling method was developed by the Escuela EMAS鑽井法是由玻利維亞的Escuela Móvil de Agua y Saneamiento (Mobile School for Water and Sanitation, EMAS) in Bolivia. Project leader of EMAS in Bolivia is Wolfgang Eligius Buchner, born 1957 in Holzkirchen bei München. Saneamiento（水與衛生流動學校）所開發。EMAS在玻利維亞的計畫領袖沃夫岡・埃里吉斯・布赫納，於1957年出生在慕尼黑的霍爾茨基興鎮。EMAS建立於1993年，已在聖胡利安（1994年）及裴瑞玆（1997年）的部門培訓了約130位獨立造井師，其中有20位學生從認證過的工藝課程中畢業。玻利維亞的造井師們創立了一個造井師組織。
EMAS was established in 1993, and has provided training for about 130 independent well builders in its branches in San Julian (1994) and in Puerto Pérez (1997). 20 students have been able to graduate from the licensed craftsman course. The well builders in Bolivia have founded a well builder organization. EMAS建立於1993年，已在聖胡利安（1994年）及裴瑞玆（1997年）的部門培訓了約130位獨立造井師，其中有20位學生從認證過的工藝課程中畢業。玻利維亞的造井師們創立了一個造井師組織。
During a three-month education, agricultural workers are trained to independently drill wells, build sanitary installations and market their skills in their local area depending on demand. The need for large financial investments for well drilling and the building of line systems has traditionally prohibited the construction of large scale potable water systems in rural areas. Wolfgang Buchner adapted already accepted suction - and rinsing drilling methods to local conditions. 三個月的訓練過程中，農業工人受訓如何獨立鑽井、建造衛生設施、及在當地社區視需求推廣自己的技術。因鑽井及建造線路系統需要大量投資，所以一直以來難以實現在郊區建造大規模的飲水系統。沃夫岡・布赫納依照當地情況，改建了原本受到大眾接受的吸式及沖洗式鑽井系統。
EMAS is not only the name of the mobile school for water and sanitation, but also a whole technical and social concept of water and sanitation which includes rain water harvesting, solar water heaters, windpower, hydraulic rams, water treatment, small tanks and sinks, a variety of hand and foot pumps, and ferrocement tanks.EMAS不只是水與衛生流動學校的名字，也是整個技術及社會對水和衛生的概念；包含收集雨水、太陽能熱水器、風力發電、液壓頂桿、水處理、小型貯水池與水槽、各式各樣的手泵與腳泵，及鋼筋混凝土貯水池。
