We offer end-to-end water and wastewater treatment solutions including Sewage Treatment Plants (STP), Effluent Treatment Plants (ETP), Reverse Osmosis (RO) Plants, Zero Liquid Discharge (ZLD) Systems, Rainwater Harvesting, and Swimming Pool Filtration — along with Annual Maintenance Contracts (AMC) for residential, commercial, and industrial projects.
Yes, we truly serve Pan India. Our specific hub is based in Navi Mumbai, from where our engineering, manufacturing, and service teams operate — allowing us to execute projects and provide reliable AMC support across Maharashtra and other states nationwide.
A Sewage Treatment Plant (STP) is a facility that treats domestic or municipal wastewater to remove solids, organic matter, and pathogens, so the treated water can be safely discharged, reused for flushing and gardening, or recharged into groundwater.
Preliminary treatment removes large debris and grit; primary treatment settles out suspended solids; secondary treatment uses microorganisms to break down organic matter biologically; and tertiary treatment filters and disinfects the water for safe reuse or discharge.
No. STP-treated water meets standards for reuse in flushing, gardening, cooling towers, and groundwater recharge — not for drinking. Drinking water requires additional advanced purification, such as RO combined with disinfection, beyond standard sewage treatment.
STP cost depends on capacity (KLD/MLD), technology used (MBBR, SBR, MBR, etc.), site conditions, and civil work required. Since every project's requirement is different, we recommend requesting a free consultation for an accurate, custom quote.
Microorganisms (bacteria) consume and break down organic pollutants during secondary/biological treatment, converting them into carbon dioxide, water, and biomass (sludge) — this is the core process that reduces BOD and COD levels.
A Water Treatment Plant (WTP) treats raw water from sources like rivers, borewells, or municipal supply to remove impurities, making it safe for drinking, industrial, or domestic use — unlike an STP, which treats used wastewater (sewage).
A wastewater treatment plant is a broader term covering the treatment of used water before it's discharged or reused — this includes STPs for domestic sewage and ETPs for industrial effluent. Both aim to remove contaminants and protect the environment, but differ in the type of source water and treatment technology used.
