'>Haifa WWTP – Upgrades
Northern Israel
This WWTP serves 11 municipalities with population of 800,000.
The treatment plant was originally built in the early 60’s for a population of 225,000 and was the first municipal sewage treatment plant in Israel.
The first upgrade and expansion of the plant took place in the mid 70’s and was designed for population of 560,000.
The second upgrade and expansion of the plant took place in the late 90’s and was designed for population of 800,000.
BJIS prepared the general and detailed design of the first and second expansions including process, civil, mechanical, electrical and control engineering as well as provided general construction supervision.
