Water is a strategic resource, and we therefore manage it in accordance with the principles of circular economy. We manage drinking water and wastewater responsibly.
We carefully monitor drinking water consumption and strive to optimise it with various activities. When constructing new facilities and renovating old ones, we use technologies for reducing water consumption, such as sensor-activated and pressure-activated taps at washbasins and drinking fountains, as well as a growing number of two-stage toilet flush systems. We adjust water flow settings, contributing to reduced water pressure and thus consumption. In the field of waterless technology, we are introducing mainly waterless urinals, but are also testing newer technologies on the market. We are systematically increasing usage of recycled and reused water, particularly in carwashes.
With the new manual car washes, we upgraded our freeze protection systems and switched to circulation through returning water to the system, which enables additional savings in the use of potable water during colder days. The newly installed manual car washes, which were built in the period 2017-2018, have increased the efficiency of washing with the introduction of hot water, while reducing the amount of time, water consumption and cleaning products. Even when choosing a heating method, we strive for maximum efficiency at each location. By 2023, we plan to refurbish most manual car washes and install new car washes at existing and new locations.
Petrol during its activities generates three types of wastewater – rainwater, industrial, and sanitary wastewater. Rainwater is discharged using technologically advanced collection systems, while we also successfully reduce emission contents in industrial wastewater using state-of-the-art oil separators.
Municipal wastewater is treated using small treatment plants where a connection to the sewerage system is not possible. We otherwise systematically strive to ensure connections to the sewerage system. Oil separators located at service stations comply with the SIST EN 858 standard. We have also implemented a new way of monitoring oil separator operations, resulting in more effective control of oil separator operation and cleaning when required.
