Full design and consulting services as well as construction supervision of the Southern Tehran Wastewater Plant, tendered as a DBO contract.
Greater Tehran with a population of about 15 million does not have a working sewerage system and no large wastewater treatment plants to date.
As a consequence, there are serious environmental and health problems in the southern part of the city where untreated wastewater is used for irrigation purposes.
That is why the city of Tehran decided to launch the "Tehran Sewerage Project". The project encompasses the construction of several large-scale wastewater treatment plants and a sewerage system which shall serve all of greater Tehran.
In 2001 the Tehran Sewerage Company commissioned ILF, together with its partner offices KEO (Kuwait) and Parsconsult (Iran), to carry out the large-scale wastewater project "Southern Tehran WWTP" for a design capacity of 2.1 million PE (1st stage) and 450,000 m³ wastewater per day.
The WWTP was conceived to permit the treated wastewater to be used without restrictions for agricultural purposes. The rapid development of the city, marked population growth and the ensuing increase of water consumption has led to an intense conflict in water utilisation with agriculture over the shrinking water resources. Wastewater reclamation will mitigate this conflict.
Another important requirement of the WWTP is that it shall generate its own power and heat as far possible through anaerobic sludge stabilisation and utilisation of the generated biogas in cogeneration plants. The heavily subsidised energy tariffs in the Iran lead to serious environmental problems (air pollution) and a general squandering of energy and money.
With the "Southern Tehran WWTP" the city of Tehran is intent on setting an example of environmental protection in the Iran and careful use of non-renewable resources. This contract enabled ILF to demonstrate its international professional competence in wastewater treatment and to play a decisive role in one of the most important WWTP projects in the Middle East.
