the country's water supply. This project was similar to Hong Kong's Plover Cove Reservoir project years earlier. However, after reviewing the conditions of the seabed, costs and environmental concerns, as well as complications involving Malaysia, because the closing of the harbour would affect shipment in the nearby Pasir Gudang Port due to the narrowing of the access strait, the plan was eventually scaled down to limited land reclamation off Coney Island and Punggol and the construction of the Serangoon and Punggol Reservoirs which instead lie within mainland Singapore. There were plans in the 1990s for a Mass Rapid Transit line to be extended towards Pulau Ubin and Pulau Tekong thus cutting across the harbour. The building of bridges or tunnels to link mainland Singapore to these islands were also considered so as to make these islands more accessible, in view of future plans to build light industries and high density housing on both islands, however due to environmental concerns and other complications the plan was shelved. There were also proposals to build a third causeway between Singapore and Malaysia with one of the suggestions being the bridge be built over the southern end of the harbour, linking Changi, Singapore and Pengerang, Malaysia, however Singapore had rejected the proposals in favour of the Kuala Lumpur–Singapore high-speed rail project and this led to the proposal being scrapped by 2016. Incidents On 3 January 2017, two vessels collided off Pasir Gudang Port resulting in a 300 tonne oil spill that floated near the Serangoon Harbour. Oil booms and buoys were deployed while the Johor Port Authority cleared the spill. There were neither injuries nor shipping traffic affected, although coastal fish farms located in the area were reported to have been affected by the spill. On 21 February 2018, Chew Eng Han, City Harvest Church fund manager convicted of misusing church funds and sentenced to three years and four months jail was caught in Serangoon Harbour off Pulau Ubin by police coast guard minutes into his attempted escape to Malaysia via motorised sampan. He was to have started his jail term the next day, after seeking deferment for the start of his term. Two people who were found to have assisted him in his escape were charged separately in court.
