Lahav, Israel

Kibbutz Lahav


In 2007, Triple-T was engaged to design and construct the retrofit of an existing wastewater treatment plant at Kibbutz Lahav, after the original system built in 2005 failed to comply with existing discharge requirements. Triple-T designed a solution to treat a complex wastewater stream from the piggery, abattoir, meat processing facility and the Kibbutz. This effluent contained high loads of organic matter and ammonia equivalent to a city of 25,000 inhabitants. The effluent discharged from the Kibbutz needed to undergo secondary treatment including the reduction of ammonia, to allow the effluent to be used for irrigation purposes.

After undertaking a two-year feasibility study, Triple-T constructed a full-scale solution using its TAYA technology to expand the facility’s capacity and increase its treatment capability.


Triple-T’s retrofit design maximized the use of the existing WWTP infrastructure, while reducing the overall land consumption by 60%. The three anaerobic basins continued to be used for selling and digestion, while two of the existing wetlands were converted into Triple-T’s TAYA system. The five remaining wetlands were not needed in the process.
