Treatment of Effluents

In order to get rid of industrial effluents in accordance with the law and with a minimum of damage to the environment, we at Ecology Services have developed a service for the quality and professional removal and treatment of industrial effluents.
Our experts will come directly to your site and conduct careful monitoring to check the concentration of pollutants in the sewage, at a certified laboratory.
Depending on the wastewater sampling, we can determine the degree of urgency and how the industrial wastewater will be treated.


Depending on the removal plan that suits you, the sewage will be removed to one of the removal terminals authorized by the Ministry of Environmental Protection.
In addition, Ecology Services offers a sewage monitoring service: According to the provisions of the law, industrial sewage producers are required to periodically sample the sewage and submit a monitoring plan for approval by the Government Ministry.
The service of our wastewater monitoring program frees you up from the meticulous preoccupation with the production and collection of sampling data and remaining updated with the guidelines of the Ministry of Environmental Protection on the subject, which change every year.

Our experts will draw up a wastewater treatment plan for you that is appropriate for the periodic monitoring results and in accordance with the guidelines of the Environmental Officer of the Ministry of Environmental Protection.
Professional care and supervision of industrial effluents will save unnecessary fines and financial expenses and of course – environmental damage.

At Ecology Services, you can also find services for the treatment of sludge – a by-product of the process of treating industrial effluents and one of the significant causes of water and soil pollution in Israel.
As part of the service, the sludge is collected for sampling and treatment at the Ecology Services plant, where it undergoes stabilization and processing processes for reuse as fuel or raw material.

Ecology Services workers carry out their work under strict supervision and in accordance with the provisions of the law for the removal of industrial effluents, and ensure compliance with the most stringent standards in the field.

Although industrial effluents make up only about 15 percent of all sewage discharged into drains in Israel, the potential for pollution and resultant damage is much higher.
Therefore, the issue of industrial wastewater treatment is highly regarded by regulators in Israel and the requirements of the law require factories, regional councils, companies and businesses to invest a great deal of resources in reporting, monitoring and treating industrial effluents.

According to the Water and Sewage Corporations Law of 2001, industrial effluents are defined as “effluents originating from the plant, which are discharged from the plant into the sewage system, excluding sanitary effluents”,


The law was expanded in 2014 to apply to regional councils and factories.

In fact, the obligation to treat industrial wastewater applies to any institution or business that does not discharge only sanitary wastewater (tap and toilets water) into the sewer system, such as: Hotels, hospitals, textile and chemical plants, laundries, garages, restaurants, gas stations, etc.

Due to the high potential for damage, the industrial bodies that discharge effluents must meet the following objectives and regulations:

  • Collecting, disposing of and purifying all sewage discharged into the drain
  • Arranging the discharge of industrial wastewater in a manner that will not cause damage to the utilization of effluent water, the wastewater treatment processes or the sewage systems of the corporation / any other entity
  • Preventing the discharge of industrial effluents that may damage the sewer systems of the corporation or any other party
  • Monitoring of industrial effluents and submitting a monitoring plan to the Government Ministry
  • Prevention of nuisances and damage to the public and the environment as a result of industrial effluents

As stated, in terms of Israeli law – treatment and purification of industrial effluents is not simply a recommendation.
Factories, institutions and businesses that do not fulfill their obligations and break the law – are slapped with huge fines, and those who discharge industrial effluents into the sewer system are charged an increased sewer tax rate, in accordance with the tariff rules.
At the same time, the responsibility for the treatment of industrial effluents is not only a commitment to the law, but also to the environment and society.

In Israel, about 86 percent of the industrial effluent is recycled and used for agricultural irrigation.

Effluents originating from industrial and commercial activity may contain high quantities of pollutants and even toxins that are not removed at the sewage treatment plant.
These industrial effluents may contaminate water and soil, damaging transmission systems or regenerating sludge and effluent – which may result in the effluent being discharged for agricultural use or discharged into the sea.

Another scenario that the law is trying to prevent is the salination of water sources in Israel so that they become unfit for drinking.
In many industries, such as food and textiles, brine is used – water to which chlorine or sodium has been added in huge quantities (more than six tons of chlorides per year or four tons of sodium per year).
Because salt is a soluble substance, the large amount of salt in the saline solution easily seeps into the groundwater, making them unfit for drinking and along the way – destroys the soil structure and impairs soil fertility.

The brine removal procedure instructs that such be transported in tankers to one of the approved brine removal terminals (at the Gush Dan Waste Treatment Plant and Haifa Bay) or that the industrial effluent is discharged into the sea in the case of factories near the coast and that a permit for discharge into the sea is issued.
