Stabilization and hydro isolation of the sewerage collection well of the city of Jurmala

An extensive sewage network was built in 2016 as commissioned by the city of Jurmala. In the course of the works, sewage collection wells of up to eight meters in depth were also installed. During the installation work, one of the sewage collection wells had been badly damaged, as a result of which groundwater penetrated through the well´s wall, constantly filling the collection well with water. Consequently, the sewage collection wells had to be emptied much more frequently than originally envisioned by the City. This, in turn, caused the sewage collection wells´ maintenance costs to be considerably higher than planned. Furthermore, relevant examinations revealed that the load bearing capacity of the soil was not correctly assessed during installation work, and by that time the collection well´s load bearing plate had begun to sink askew. This situation put the long-term use of the sewage collection well under a serious doubt. During a consultation, URETEK Baltic’s team immediately proposed to the heads of the City of Jurmala a viable solution in the form of URETEK technology, and the work was completed quickly within a few days. Relevant sewage collection wells served the residents of several multi-story buildings on account of which these buildings could not be switched over to another sewage route. URETEK Baltic’s team set very clear goals – the work must be performed quickly and professionally, while failure is not an option.
