Sewage Treatment Plants (STP)
Efficient Wastewater Solutions for Residential & Commercial Use
Our STPs are designed to treat domestic sewage generated from households, buildings, institutions, and commercial spaces. Engineered for compact design, odor-free operation, and treated water reuse, they ensure full compliance with pollution control board regulations.

Effluent Treatment Plants (ETP)
Industry-Specific Solutions for Complex Wastewater
Our ETPs are custom-built to handle a variety of industrial effluents—from chemical-laden discharge to organic waste streams. We offer both physico-chemical and biological treatment systems with options for Zero Liquid Discharge (ZLD).

Food-Based Biogas Plants
Convert Organic Waste into Clean
Energy
Our biogas plants are designed to convert kitchen and food waste into clean biogas, which can be used for cooking or power generation. The by-product—digestate—can be used as organic fertilizer.
