Process of an EMAS project
Overview
The first step is getting an overview, the assessment of the water shortage in a (mostly rural) region of a developing country.
Strategy
A decision is made as to which components of the EMAS technology can be used: is it sufficient to collect the water in the rainy season, store it in cisterns and filter it? Are there water sources from which clean water can be obtained permanently by taking appropriate measures?
Training
Finally, in the spirit of helping people to help themselves, local people are trained in compact courses lasting several weeks to become self-employed well builders and simple drinking water suppliers.
Training
Usually ten to fifteen interested and committed men and women are selected at the planned location of the project – often in cooperation with a local person responsible/a local NGO.
The course then takes place on site as a compact course, usually over a period of three to four weeks.
The training of the participants, including their accommodation and food, as well as the initial equipment, which is produced by the participants themselves, must be financed from donations. These costs currently amount to around 2,000 – 3,000 euros per participant.
In the courses, all relevant technical components are taught according to the EMAS concept. In addition, the participants are also instructed in the basics of geography/soil science, hygiene, accounting, etc.
After the course, the participants are basically able to use what they have learned as independent small entrepreneurs in their area and to sell the EMAS products at reasonable prices. They have a regular financial income, and the people in the region have access to drinking water and simple sanitary facilities.
It has been shown that the financial contribution of the local population as clients means that they pay particular attention to the wells they have bought themselves, which means that the installations are less susceptible to repairs and therefore more durable.
For this reason donated wells are only installed where the population is so poor that paying for a well is out of the question.
Repairs are usually easy to do. As a rule, these can be carried out by the well owners themselves or by the well builders.
If necessary, the well builders can also contact the trainer with technical questions later on. Advanced courses can be held on request.

EMAS Tube well
Flush drilling is mainly possible in sandy, clayey soils. Thinner rock layers can also be drilled through. Drinking water layers are often found at a depth of 15 - 30 m, and wells up to 90 m deep have been drilled to date. In contrast to a dug shaft well, a tube well is closed and thus protected from contamination. The misdrilling rate is about 10%, which is about the same as the rate of commercial wells. Per day, about 10 - 30 m deep can be drilled by hand. The water is pumped through the plastic pipe, which is sunk into the ground, with the help of the EMAS pump.
EMAS pump
The patented EMAS pump is created from plastic pipes, a glass shot as a valve, and pieces of metal welded together (despite the patent, it should and may of course be used freely by all interested parties). The pump is used for the EMAS tube wells, but also to pump water from cisterns, old dug wells (which are sealed at the surface for hygienic reasons), etc.
Cisterns, tanks, sinks
They are made with reinforcement of iron wire and strong ferrocement. They can be placed inside the house, that is, where the water is needed.
Dry toilets
They are also made of ferrocement, they contain a simple exhaust device.
The water is pumped into a tank on the roof of the shower enclosure. Solar radiation, possibly with the help of solar collectors, makes it possible to obtain hot water.
Showers
The EMAS-technology offers a solution to these problems
Improved access to clean drinking water for the rural population worldwide, combined with simple sanitary facilities, thereby avoiding infectious diseases and reducing mortality.
Increased quality of life, among other things, by eliminating the tedious task of carrying water, thereby saving time, especially for women and children, enabling small-scale farming.
Better chances for people to be able to live permanently in their accustomed place.
Help to self-help: the trained well builders are independent and self-sufficient, but can be advised and trained again if necessary.
Sustainability: The wells and water facilities are very inexpensive, experience has shown that the owners take good care of the systems, which means that they have a long service life. Any necessary repairs can usually be carried out very easily.
The water problem
The problem is not new, but it has increasingly come into focus in recent years, also due to the current discussion about climate change. In large areas of the world, people have little or no access to clean drinking water.
The consequences are known:

The consequences are known:
Increased infant mortality
Many people fall ill with preventable infections, and child mortality in particular is increased.
Difficulties in schooling
When access to – distant – water sources is difficult, it is usually women and children who have to fetch water. They lack this time for other work and school attendance.
Rural exodus
Without sufficient water, it is hardly possible for the rural population to live decently in one place, to make an adequate living and to settle down. Consequences among other things are slash and burn, as well as rural exodus
Students will learn how to make a complete drill rig.

At the end of the course, participants are allowed to take their self-built drilling equipment with them.
