LA TÉCNICA

EMAS se ha forjado a lo largo de los años, paso a paso, aprendiendo y adaptandose al lugar donde colabora, a su gente, a su cultura, a su forma de vivir y entender la vida.

Esta parte social sin la cual la técnica no podría desarrollarse  es la que ha permite a EMAS materializar el concepto de SOSTENIBILIDAD.

This movie gives a short impression of the EMAS training center in Puerto Perez, Bolivia.

BOMBAS EMAS do it your self a partir de trozos de tubería

Pueden ser hechas de diferentes maneras. Las válvulas pueden ser hecha de conectores o de pedazos de tubería. Aquí se muestra la versión hecha con trozos de tubería

EMAS standard drilling system

This hand-drilling system was developed by EMAS in Bolivia. It can reach 100 meters depth. 30 meters are normal for the first day. The cost of a 30-meters well is around 200 Euro including hand pump. Local drillers offer their services and do the drilling together with the families. The EMAS pumps were designed especially for these boreholes with reduced diameter.

Odourless and inexpensive EMAS latrines

There exist two types of EMAS latrines, the permanent one has a fecal chamber which can be emptied and a temporary type. Here the whole cubicle is changed to another pit. The cubicle itself is made in a nice, stable, cheap and durable way.

EMAS solar water heater using glass bottles and PVC pipes

This simple type of solar heater is easy to build and very efficient. Because of its water volume it is night frost resistant and (using polypropylene fittings) also corrosions free. This type does not need a warm water tank if warm water is used during day. How to make the warm water storage tank is shown on a separate movie

Solar heating – hot shower using bottles

This movie shows a bottle heater, where the hot water is used for a shower.

EMAS underground cisterns for rain water harvesting

An EMAS cistern with 7000 liters needs about 5 bags of cement (50 Kg). It can be washed within a few minutes without entering, it is low cost and long lasting. Several tanks can solve the need of water during the whole year. To make rain water drinkable is shown in another

how to make a small ferrocement tank

Small ferro cement tanks are useful for household water storage, for grain storage, spring catchments, improved hand dug wells and many more…..

Ferrocement tank using a temporary inner form

This ferro cement tank needs only binding wire instead an iron cache. It is cheaper and easier to build in case there is a demand for more pieces.

EMAS underground cistern made in pure sand

Often it is said, that making an EMAS underground cistern in pure sand (just plastering the earth wall with cement mix)is not possible because of collapsing the digging. Here is shown a technique where this is possble. By the way, a cistern in pure sand very seldom cracks and is more stable than in hard clay soil.
