Wastewater Treatment Plant, WWTP is a structure that is designed to remove biological and chemical waste from water so that it can be used in other activities. The WWTP functions include :

Urban wastewater treatment, to dispose of human waste and other household waste.

Industrial wastewater treatment, to treat wastewater from industrial and commercial manufacturing activities including mining activities

WWTP, usually stored underground, when WWTP has a leak because it is not neglected this will cause big problems. The waste content in the WWTP can leak into the ground water. Therefore, it is not surprising that there is well water near the industrial WWTP that tastes salty or well water near WWTP Human waste that smells unpleasant.

Therefore, special attention needs to be paid to the condition of WWTP, so that what is contained in the waste inside does not pollute water in the soil. Because of the pressure of the content in the waste can enter pollute ground water.
