The accumulation of raw sewage, indiscriminate dumping of trash and buildup of sediments over the years had caused severe pollution in the Melaka River.

There were two stages to the restoration works of the river. Sewage treatment plants were first constructed along the river to ensure all domestic and industrial wastewater entering the river was treated. Thereafter, the remediation works were carried out to remove the contaminated sediments and reshape the geometry of the river to enable it to be naturally self-flushing. Some 570,000m3 of sediments were dredged and dewatered.
