Kuryanovskiy sewage treatment plant was established in 1950. In autumn 2012, the Kuryanovskiye WWTP was upgraded to world’s largest ultraviolet (UV) disinfection plant, with a capacity of 3.125 million m³/day (180,000 m³/hr) consisting of 17 open channels.

Each channel is equipped with 5 UV banks in series, each UV bank consisting of two in parallel placed vertical UV modules. With this configuration the total hydraulic headloss over the UV system at peak flow is less than 30 cm w.c. All tests results are compliant with the design parameter and state standards SanPiN 2.1.5.980-00 – Hygienic Regulations for Surface Water Protection. Total coliforms less than 500 CFU/100 ml, Fecal coliforms less than 100 CFU/100 ml and Coliphages less than 100 PFU/100 m. The total treated effluent represents 50% of the total flow of the Moscow River and 90% of its tributary – the Pekhorka River.
