Contractors in St Petersburg are casting ring beams to strengthen 50m diameter primary settlement tanks for a massive £50M water and treatment works. Black & Veatch Consulting is acting as supervising engineer on this third attempt to build the project, which will cut pollution in the Baltic.

Construction began in 1991 but was shelved after the collapse of the Soviet Union. An attempt to restart it failed in 1995. Initial work involves repairs to existing structures. When complete the plant will serve a population of 750,000.
