On the project of new sewage treatment facilities (WWTP), a pressure pipeline was built from the Tengiz shift camp to the water treatment plant, with a length of 2 km. At the same time, 26 reinforced concrete wells were manufactured and installed. The WWTP project replaced the outdated sewerage and water treatment system built in Tengiz to support the technological process at the TGPZ and service shift camps back in the mid-1980s
