The project will commence in March 2011, with a construction period of 9 months.
Angerlehner said “Our teams have been working together with local partners and subcontractors for more than six years already and are familiar to the local conditions and challenges in India.”
Scope of the work includes de-silting works as well as CCTV and non man entry surveys to study the actual condition of the sewer.
The brick sewers, which are located under streets with high volume of traffic, have a diameter between 600–1,050 mm in circular profile and 1,050/700 mm – 1,425/600 mm in egg-shaped profile.
