Special Profile 1000 Meter Sewer Reabilitation in Basel
After 70 years of service the approximately 1-km-long deteriorated concrete relief sewer Leimgrubenweg/Walkeweg in the Swiss canton Basel-Stadt Switzerland could be no longer maintained with spot repairs. Extensive preliminary investigations and an in-depth evaluation of possible solutions commissioned by the Municipal Works Service Department for Municipal Sewage of the canton Basel-Stadt in Switzerland led to a sliplined HOBAS NC Line solution that ensures trouble-free service for a minimum of 50 years.
