OBJECT; Feasibility Study Up-Date for Programme Implementation.

It is obvious that water management in Vietnam is of particular importance, because of the different climatic premises and the increasingly extreme weather conditions. Due to low elevations in most parts of the country, any water management is demanding.
Hai Duong City especially suffered from frequent flooding, due to the sewers either being blocked, having insufficient capacity or being non-existent at all as well as the pollution of lakes, ponds and canals by sewage and the infiltration of wastewater into the soil.
Thus, a Feasibility Study describing improvement measures had been prepared by local consultants, which was updated by KOCKS Consult GmbH.

KOCKS Consult GmbH first analysed two alternatives for the sewer system, which showed the combined system to be the most favourable under the prevailing conditions.
As further measures, the Consultant proposed the repair and reconstruction of existing sewers; construction of new combined sewers; construction of new storm water overflow structures; dredging of lakes and ponds; construction of new pumping stations; paving of embankments near outlets as well as the construction of a wastewater treatment plant.
Hai Duong City would profit from these measures, as there would be significantly less discharge of sewage into the watercourses, which would improve the environmental situation in the adjacent areas. The flooding frequency within the city centre would be reduced and the overall environmental situation will be enhanced, since the sewage will be treated prior to discharge into the canals.
The Consultant furthermore recommended the project to be implemented in several stages.
