STP stands for “Sewage Treatment Plant.” It is a facility designed to treat and process wastewater (sewage) before it is discharged back into the environment or reused for various purposes. The primary goal of an STP is to remove contaminants, pollutants, and harmful substances from wastewater to prevent water pollution and protect public health.

STPs are essential in maintaining water quality and safeguarding the environment against waterborne diseases and pollution. Properly treated wastewater helps protect aquatic ecosystems, supports sustainable water use, and ensures the health and well-being of communities.
