Building compact decentralised wastewater treatment plants - MBR (membrane bioreactor)

Project ongoing since: 2011 • Triple E s.a.r.l


An opportunity for a decentralized organization, a highly evolutionary and sustainable solution for the sewage system


Centralized solutions for wastewater treatment have not worked in Lebanon and the countries of the third world. These countries and especially Lebanon lack functional wastewater treatment plants. Sewage networks are poorly maintained and not all households are connected. In many rural areas, septic tanks are dug into the ground to collect sewage which seep into groundwater.

The septic tanks are emptied by trucks where the sewage is dumped in other areas causing further pollution. Compounding the problem, third world countries face frequent water shortages which leads to water rationing by the government. As a result, citizens are forced to purchase water for drinking and even domestic uses.
The extremely dangerous human wastes cause environmental and social problems especially with, regard to people’s health and wellbeing.

Triple E (Environment Evolution Engineering) offers a solution: The decentralization of the sewage system has proved that it is profitable all over the world: in the countries of the Third World and in Europe….. In fact, nowadays, the cities around the whole world tend to decentralize to avoid the high costs of the infrastructure. For example, in the case where we want to treat the sewage of a certain village, we should execute the painful civil works of excavation first and then we build a suitable network of sewers to be able to guide it to a big treatment station.

This is why Triple E offers an opportunity for a decentralized organization, a highly evolutionary and sustainable solution for the sewage system.

Triple E offers a simple and proved technology: MBR (membrane bioreactor). The MBR system is a robust process not only by its treatment efficiency but also and particularly by its technical simplicity and its weak consumption of energy and maintenance need as well as its flexibility of adaptation with the influent category.

Countries of activity

Location of main activity


A- Environmental Impact
- Decrease the hydraulic stress by increasing the quantity of recycled reused water.
- Creation of new opportunities for reusing of the waste water.
B- Impact on the health and hygiene
- Reduce the average of diseases related to polluted water.
C- Creation of jobs and promotion of the culture water recycling
- Recruitment of university students for part time jobs.
- Proposition of research and applications subjects for engineering students in collaboration with universities.

Our mission is to increase the public awareness in order of to solving the problem caused by the residential waste water and to reach the time where this type of water is in treated by plants at the national and international level. What will decrease as well the pollution and related diseases, the hydraulic stress as well as creating new job opportunities and activating the economical chain.

Our objective is to conceive an organization, a well organized enterprise capable of reaching the targeted public, by offering the most technological treatment stations at the lowest prices, solving the needs for water and sanitation and therefore improving their life style.

Further information

Since the populations and the urbanism progress rapidly, the cities and States fight to manage the increasing demands in water, and food, in infrastructure and social services.
This will have a combined effect in reducing considerably the number of septic tanks and the throw of sewage water in the environment (soil, rivers, sea…). So our project targets the population who suffers from the lack of water and/or a problem of the drainage and sanitation. So, we target in our studies the houses, residences, buildings, compounds and villages.
The positive side regarding the market is that it is in continuous growth and will never reach a phase of setback.Our main actors are the municipalities responsible of evacuation plans for waste water and for environmental protection and pollution’s control. And we target the consulting companies which will mark the necessity of the treatment station in the residential projects.
