Date of publication: 17 December 2020

Transneft Volga Region has completed the implementation of a significant environmental project: the revamping of the water supply and water disposal system of the oil blending station (OBS) of the Samara site in Volzhsky District of Samara Region.

The set of works was launched in May 2018 as part of the technical upgrading, revamping and overhaul programme of the company’s facilities. The goal is to comply with high standards of environmental safety in operational activities, exclude unorganised discharge of surface runoff onto the terrian from the territory of the operating facility in accordance with the requirements of environmental legislation of the Russian Federation.

The outdated water supply and water disposal system of the oil blending station, which had been operating since 1979, was dismantled. For water supply to the facility, 4 horizontal water tanks with a capacity of 100 m3 each were built, a pumping station for utility and drinking water supply with a water treatment plant and two pumped storage tanks were equipped, a utility and drinking water supply water line with a length of more than 3.4 km was laid, 23 wells of water supply networks were equipped.

As part of the project implementation, a wastewater biotreatment station with a capacity of 100 m3 per day was built. It is the first station with such a high capacity at the facilities of Transneft Volga Region. Its commissioning will allow to treat utility water collected from the entire Samara operating facility, including the Samara-1 PS, the Samara-2 PS and the oil blending station. In addition, 14 sewer pump stations were built, new household and utility and storm water sewage lines with a total length of 7.2 km were laid, 254 wells were equipped.

The design of water supply and water disposal facilities at the OBS was carried out by Samaragiprotruboprovod, a branch of Giprotruboprovod. The complexity of the implemented measures was that construction and installation was carried out in space-limited environment of existing communications and was accompanied by a large volume of earthworks in trenching and pits excavation with a depth of 7-9 metres with the need to perform additional fastenings of the trenches’ slopes.

The new water supply and water disposal systems were commissioned after comprehensive testing and are operating under the standard protocol.
