Sewerage for the industrial waste of Singapore

National Environment Agency: "Given Singapore's limited water resources, it is critical that water pollution and quality are carefully monitored and regulated. The responsibility for this belongs to the National Environment Agency (NEA), which regulates water pollution and quality in Singapore's sewerage system, as well as inland water bodies and coastal areas. The control of soil pollution is also an important aspect in this regard, given that pollutants in the soil are likely to make their way into the water system as run-off or groundwater. Soil pollution control in Singapore primarily focuses on the use of approved pesticides to combat termites in soil. Further details can be found here."

The National Environment Agency suggests the situation of water pollution to be monitored and reduce the amounts of pollutants. The NEA is in charge of the sewerage in Singapore and inland water bodies. But what would happen if the system were to fail?
