II stage of reconstruction of Sillamäe water and sewerage pipelinesSillamäe, Ida-Virumaa

The design and construction project for the city of Sillamäe’s water mains and bore wells will ensure that residents have access to drinking water of the required quality. As part of the second phase of the project, AS Merko Infra renovated and built 11 km of water pipelines and close to 12 km of sewerage pipelines. In addition, two pumping stations were rebuilt and one water treatment station was improved. In the second phase, were designed, renovated and built a total of 11.4 km of water pipelines, 10.3 km of downstream sewerage pipelines and 1.4 km of pressurized sewerage pipelines. Also were renovated two bore well pumping stations and improved one water treatment station. For the purpose of improving water quality, ultraviolet light (UV) equipment were installed in the central and micro-pump station and in the bore well pumping station no. 8. Disinfection of water using UV radiation consists of exposure of any micro-organisms in the water to the required UV radiation dose.
The work in the first phase of the Sillamäe water and sewerage piping was performed from 2010-2012, also by Merko. In the course of this phase, 11 km of water pipelines and 15 km of sewerage pipelines was installed, along with 11 bore well pumping stations, two waste water pumping stations, two level 2 pumps and one water treatment station.
