Namangan Water Project - NWP-12 Hypochlorite plant at Kyzyl-Ravat water intake

Project Site

The Kyzyl Ravat Water Treatment Plant is located in eastern Uzbekistan in the Namangan Region, between the city of Namangan (population over 1 million) and the city of Andijan (population approximately 600,000).

The plant is situated in the city of Uchkurgan (Uchqo’rg’on), which has a population of around 50,000 and lies directly on the border with Kyrgyzstan.

Project Goal

Previously, the disinfection of 3,000–4,000 m³/h of drinking water was carried out using chlorine gas stored in large drums. The installation dated back to the Soviet era and had reached the end of its operational lifetime.

The system was replaced with two automatic sodium hypochlorite production lines producing a solution with 0.6–0.8% free chlorine. Each line has a production capacity of 7 kg/h, resulting in a total output of 378 kg of free chlorine per day. The sodium hypochlorite is produced from locally available salt (NaCl) through electrolysis.
