The Tunnel and Reservoir Plan (abbreviated TARP and more commonly known as the Deep Tunnel Project or the Chicago Deep Tunnel) is a large civil engineering project that aims to reduce flooding in the metropolitan Chicago area, and to reduce the harmful effects of flushing raw sewage into Lake Michigan by diverting storm water and sewage into temporary holding reservoirs. Tan, Lee and Tan, Clean, Green and Blue, 18788; Tan, Water, 2930.3. Domestic policy (Water Resource Management) The new deep tunnel system will make use of gravity for the collection of sewage. CH2M Hill and its joint venture partner Parsons Brinckerhoff conceptualised and managed the planning, design and construction of the DTSS phase I. Samsung Engineering and Construction was awarded the construction contract for a portion of the tunnels under DTSS phase I.Other contractors involved in Phase I included the TMCR Group, Ah Boon Civil Engineering and Building Contractor, Sembawang Engineers and Constructors, Penta Ocean Construcion Company, KTP Consultants and AKS Lining Systems. This was the first rock fissure grouting in Singapore and was carried out with the help of our Global Product Team and prior experience in Malaysia.

Singapore's Deep Tunnel Sewerage System will address the issue of both water and land scarcity in Singapore with a network of tunnels, pipelines, water reclamation plants and ocean outfalls. It will consist of 40 km of deep tunnels, 60 km of link sewers, and a specialised industrial sewer network. The second phase of the project began in 2016 and involved extending the tunnel system to the west of Singapore and constructing an advanced, state-of-the-art water reclamation plant. In addition, the lining is also required to be as watertight as possible.
