Effluent quality
Treated wastewater is known as effluent. The treatment plant produces about 38 million m³ of effluents each year.
Effluent quality at the plant is very good, primarily with respect to the removal of organic compounds from the raw sewage.
Effluent quality during the last few years is shown in the table below.
Effluents are used in irrigation. Most effluents are sent through a pipe by the Mekorot Water Company to the Jezreel Valley and are stored in reservoirs operated by a farmers’ cooperative (Tishlovet Kishon) having a total capacity of about 25 million m³.
The effluents are used during the summer months for crop irrigation.
A small portion of the effluent is used for irrigation of the fields of Kibbutz Yagur next to the treatment plant.
