Daugavpils is a junction station of the Latvian Railway.
In the postwar years, Lentransproekt (since 1951 - Lengiprotrans) participated in the design of the restoration of water supply and sewerage facilities destroyed during the war. In particular, a reconstruction project was prepared at the Daugavpils station.
In general, the institute carried out restoration work at 14 water supply and sewerage facilities in the Latvian SSR.
The design work on capital restoration of water supply and sewerage facilities was preceded by:
• survey of water supply sources and sewerage water intakes;
• preparation of technical characteristics of devices;
• topographic survey for the designed devices;
• survey of existing devices of water supply and sewerage networks;
• engineering and geological survey of construction sites;
• drilling exploration and production wells, if necessary.
