Waste water treatment
In Petrol, we manage concessions for performing public services for the wastewater collection and treatment.
In 2017, we managed four concessions for performing public services for the wastewater collection and treatment. The treatment plant in Murska Sobota has the capacity of 42,000 population equivalents (PE), Sežana 6,000 PE, Ig 5,000 PE and Mežica 4,200 PE. As an important shareholder in the company Aquasystems d.o.o., Petrol d.d., Ljubljana, also participates in the treatment of urban wastewater in the City Municipality of Maribor with a capacity of 190,000 PE.
All of the treatment plants were performing well in 2017, there were no major technical failures and they reached the predicted effects of wastewater treatment.
