Lorong Halus Wetland

Lorong Halus Wetland is a constructed wetland on the eastern bank of Serangoon Reservoir, in the Pasir Ris planning area, built in 2011 on part of a former landfill. From the 1950s, swampland around the Serangoon Sludge Disposal Works was used as a refuse dump, and within two decades the landfill had grown to 234 hectares, with refuse mounds as high as 10 storeys. When Serangoon Reservoir was built in the 2000s, the Public Utilities Board turned a portion of the old landfill into a wetland to treat water passing through it before it can reach the reservoir.

Visitors can follow PUB's self-guided ABC Waters Learning Trail, which explains how the wetland uses bioengineering to treat leachate, the polluted water that seeps from landfill. PUB describes the site as a favourite birdwatching spot in the east, and NParks names Chestnut Munias and Little Grebes among the birds seen from the 3km Lorong Halus Park Connector beside it. The red Lorong Halus Bridge, styled after an old steel railway bridge, links the wetland with Punggol Promenade, and the East entrance of Coney Island Park lies nearby. Bus services 58, 88, 359 and 518 serve the park connector.
