El-Hamra Reservoirs and WWTP

General Background El-Hamra WWTP serves 3 regional councils Majd elShams, Buq'ata and Mas'ade having population of 28,000 at the end of design period.
There are 6 Reservoirs integrated in the plant: 2 anaerobic lagoons 7,000 m³ each, 2 aerated lagoons of 7,200 m³ and 7,300 m³, 180,000 m³ settling lagoon, and 260,000 m³ effluent reservoir. The plant was completed at 2005. The plant consists of semi-intensive facilities, i.e. a combination of anaerobic and aerated earth lagoons.
BJIS provided general design and complete detailed design services as well as general supervision of construction. Basic Design Facts

Mahanayim Reservoirs

General Background
Mahanayim twin effluent reservoirs are located north to Rosh Pinna - Kfar HaNassi road, and west to the Rosh Pinna river.
The reservoirs are fed with effluent from a near-by WWTP and supply effluent water to agricultural plantations in the region. BJIS provided the general design, complete detailed design services, and the general supervision of construction.
