Environmental services

Large selection of high-quality,
environmentally friendly solutions.

Treatment of waste water and supply of drinking water to local communities. Planning solutions for waste management. Rehabilitation of environmental problems. These are the areas where we are collaborating, contributing, developing and fulfilling a common vision of responsibility to the environment.

Careful management of water is becoming the highest priority in society, and one that is not just important to the environment, but to our very lives.

The exchange of knowledge, innovation, environmental safety and an accessible range of services for managing water resources are becoming a strategic advantage in the selection of energy services offered by the Petrol group.

Murska Sobota treatment facility

Based on a concession acquired in 2002, the Petrol company constructed a treatment facility in Murska Sobota. The project covers 42,000 population units and includes mechanical treatment, biological treatment of carbon and nitrogen compounds, chemical precipitation of phosphorus compounds and also above-standard purification through stone filters and disinfecting with UV light. Following a successful period of trial operation, the treatment facility started full operation in April 2005. In addition to urban waste water, the facility also treats technological waste water from local industry, while it is also able to receive and treat cesspool effluent.

Mežica treatment facility

In 2001 Petrol acquired a concession to construct and operate a treatment facility in the municipality of Mežica.
