Sewerage EPC Contractor & STP Construction Company India

VRSIPL specialises in MBBR (Moving Bed Biofilm Reactor), SBR (Sequencing Batch Reactor), ASP (Activated Sludge Process), and MBR (Membrane Bioreactor) technologies for STPs, all meeting CPCB and SPCB effluent discharge norms.

Yes, VRSIPL has executed sewage treatment plants and sewerage network projects under NMCG (National Mission for Clean Ganga), AMRUT, and Smart Cities Mission for pollution abatement of rivers and urban sanitation improvement.

VRSIPL has delivered 200+ MLD of combined STP capacity across 15+ cities in Gujarat, Madhya Pradesh, Maharashtra, Rajasthan, Uttar Pradesh, and other states, treating wastewater before safe discharge or reuse.

Yes, VRSIPL executes complete underground sewerage networks including trunk sewers, branch sewers, and house connection laterals in RCC (NP3/NP4), DWC, and VC pipes at designed hydraulic gradients with IS:4111 manholes at regular intervals.

Yes, VRSIPL uses pipe jacking, micro-tunneling, and slip-lining trenchless methods for sewer installation in urban areas, busy roads, and cross-road locations — eliminating open trench disruption in city sewerage networks.

VRSIPL-delivered STPs achieve treated water quality of BOD < 10 mg/l, TSS < 20 mg/l, and Coliform < 1000 MPN/100ml — meeting CPCB/NGT standards for discharge into surface water bodies or reuse for non-potable purposes.

Yes, VRSIPL constructs sewage pumping stations (SPS) — wet well, dry well, or submersible type — with duty/standby pump arrangement, SCADA integration, automatic level controls, DG backup, and odour control systems.

Yes, VRSIPL has post-construction O&M capability for sewage treatment plants, offering operations, maintenance, and performance compliance services during the defect liability period — ensuring consistent CPCB compliance after handover.

Yes, VRSIPL is an experienced STP contractor operating across Gujarat and Maharashtra, having executed sewage treatment plants for AMRUT, Smart City Mission, and municipal corporation projects. Projects include STPs from 2 MLD to 50+ MLD capacity using MBBR and SBR technologies.

MBBR (Moving Bed Biofilm Reactor) is a compact, high-efficiency sewage treatment technology where plastic carriers provide a moving surface for biological degradation. VRSIPL uses MBBR for STPs in space-constrained urban areas because it requires less land, handles load fluctuations well, and consistently achieves BOD < 10 mg/l with low sludge generation compared to conventional ASP.
