Why correct STP supplier selection matters?

Sewage Treatment Plants (STPs) are long-term investments. A good supplier ensures proper design, operation efficiency, compliant treated water quality, reliable maintenance and spare support. Wrong supplier or low-quality components can cause plant failure, odour, environmental non-compliance — costing much more later.
