The lack of investment in Sewerage Treatment Plant (STP) operators has led to a decrease in the quality of water and increase in water pollution. This has dire consequences such as water borne diseases, destruction of aquatic life, and degradation of the environment. it also affects local industries as they rely on clean water for their production processes.

Therefore, it is essential to invest in providing adequate resources to STP operators to ensure safe and clean water. This includes providing proper training, access to the latest technology, and updated safety protocols. governments should create incentives for private companies to invest in STP operators so that they are able to provide the best services.

This will ultimately help in protecting the environment and keeping people safe from water-borne diseases.
