The presentation entitled ‘Laying of Interceptor Sewers along Najafgarh, Supplementary and Shahdara Drains for Abatement of Pollution in River Yamuna’ was made by him. He informed the audience that the Interceptor Sewers Project has been conceived for abatement of pollution in river Yamuna. It aimed to developing a 58 km long Interceptor Sewer network for conveying trapped sewage from unsewered area sub-drains to STPs through microtunnelling methods. He informed that activities such as field investigations, preparation of detailed feasibility and project report, land allotment process and issuance of tender documents has been completed.
In the second workshop, Mr. Karl Dewstow, Trenchless Solutions Specialist, Worldwide Machinery Solutions, delivered the presentation entitled ‘Large HDD Rig Selection and Setup’. Initiating presentation with the introduction of the drilling machines, he explained that the selection of appropriate machine depends upon machine pilot bore distance capability, machine hole size capability and machine pullback force. During his presentation he presented detailed specifications and benefits of the machines and tools in such projects.
The workshop on ‘Trenchless Technology Selection Guidelines’ comprised two presentations. The first presentation entitled ‘Selection of appropriate technology for trenchless solutions and techno-commercial evaluation of bids’ was presented by Mr. Vidyadhar M Vengurlekar, Expert (Sewerage Rehabilitation), Mott MacDonald Private Limited. Beginning with the introduction of the Trenchless techniques employed for new installations as well as rehabilitation and replacement of the subsurface utilities, Mr. Vengurlekar emphasized on the importance of the selection of appropriate trenchless techniques and selection of qualified contractors to execute projects, through proper screening procedure. He suggested the process of identifying and giving Weightages to the various driving factors responsible for the trenchless technology selection and selection of contractor.
