Emergency Services

Singapore’s climate is characterised by heavy rainfall averaging at about 167 days per year. This poses a unique challenge to the utilities agencies as it may lead to flooding of streets or residential areas due to a choke in the drain or manhole bursts. Sewer lines may also get choked due to heavy silt deposits, grease accumulation or other obstructions leading to sewage overflowing from manholes.  

Lian Shing provides a variety of emergency services and solutions for urgent call-out related to choke in drains and sewer pipelines, siphoning holding tanks, over-pumping, manhole bursts etc. We also provide heavy pumps for overpumping or diversion of sewer lines during sectional maintenance or repairs.
