Sewage Treatment Plant Solutions in Salt Lake
Salt Lake City (Bidhannagar) is one of Kolkata's most planned urban townships, home to over 200 residential societies, IT hubs like Sector V, and major commercial complexes. With rapid vertical development across sectors I through V, the demand for reliable sewage treatment solutions has grown exponentially. WBPCB regulations mandate that residential complexes above 20,000 sq ft and commercial establishments generating more than 50 KLD of sewage must install and operate an STP. ZEXCORP, headquartered right here in Sector V at Aurora Waterfront, is the trusted STP partner for Salt Lake's residential and commercial establishments.

Why Choose ZEXCORP for Your STP in Salt Lake?
Salt Lake's planned grid layout across six sectors creates unique STP design requirements. High-rise apartments in Sectors III and IV require compact MBBR-based STPs that fit within limited basement space. The IT corridor along Sector V — housing TCS, Wipro, Infosys, and Cognizant campuses — demands commercial-grade STPs with higher capacity and stricter treated water quality for landscape reuse. ZEXCORP's proximity to these establishments (our office is in Aurora Waterfront, Sector V) means we provide same-day response for any STP emergency.

Frequently Asked Questions
How much does a STP cost in Salt Lake?
The cost depends on capacity (KLD), technology chosen, and site-specific conditions. As a general guide: a 10 KLD MBBR-based STP costs INR 3-8 Lakhs, 50 KLD systems range from INR 15-30 Lakhs, and 100+ KLD systems start at INR 25-50 Lakhs. Civil works, electrical connections, and SCADA integration are additional. Contact ZEXCORP for a customized quotation based on your exact requirements.
What STP technology is best for my project in Salt Lake?
The optimal technology depends on your space constraints, treated water quality requirements, and budget. MBBR is the most popular in Salt Lake due to its compact design and consistent performance. SBR works well for projects with variable wastewater flows. MBR produces the highest quality treated water suitable for direct reuse. ZEXCORP's engineers will assess your site and recommend the most cost-effective solution.
Does ZEXCORP provide STP maintenance and AMC in Salt Lake?
Yes, we provide comprehensive O&M and AMC services across Salt Lake. Our maintenance contracts include daily operations management, chemical dosing optimization, sludge handling, equipment servicing, and WBPCB compliance monitoring and reporting. We offer flexible monthly, quarterly, and annual contract options.
How long does STP installation take in Salt Lake?
A typical 10-50 KLD STP installation takes 45-90 days from design approval to commissioning. Prefabricated and containerized systems can be installed in as little as 15-20 days. Larger systems (100+ KLD) may take 3-6 months. ZEXCORP provides a detailed project timeline during the proposal stage.
What are the WBPCB discharge standards for STP in Salt Lake?
WBPCB mandates that treated sewage must meet these standards before discharge: BOD < 30 mg/L, COD < 250 mg/L, TSS < 50 mg/L, pH 6.5-9.0. For reuse applications, stricter standards apply. ZEXCORP designs all systems to comfortably exceed these requirements, typically achieving BOD < 10 mg/L and TSS < 10 mg/L.
Can ZEXCORP help with WBPCB STP compliance in Salt Lake?
Absolutely. We handle the entire compliance lifecycle — from CTE (Consent to Establish) application before construction, through CTO (Consent to Operate) after commissioning, to annual renewal and OCEMS integration. Our team manages all documentation, liaises with WBPCB officials, and ensures your STP meets all regulatory requirements.
