DEWATS for domestic wastewater: Abdul Rahman Great Mosque in Kabul, Afghanistan

The Abdul Rahman Great Mosque, inaugurated on the 20th of July 2012 by Afghan President Hamid Karzai, was designed to serve more than 10,000 Muslim visitors per day. Completed in 2009, the Abdul Rahman Mosque is one of the biggest mosques in Afghanistan. There is also a madrasa inside the mosque and a library containing 150,000 books.

BORDA attached a DEWATS system to the mosque's already existing but under-dimensioned settler, in order to more efficiently treat the wastewater coming from the toilet complex. The treated wastewater is used to irrigate the garden, with any excess discharged into a nearby drain. Due to limited space, a 2-level anaerobic baffle reactor (ABR) was implemented.
