Goa, renowned for its pristine beaches, vibrant culture, and thriving tourism, faces a less visible but critical challenge: effective sewage management. As urbanization and tourism boom, the strain on Goa’s sewage infrastructure intensifies, threatening water resources, public health, and the state’s ecological balance. In this blog, we explore Goa’s sewage treatment scenario, the issues at stake, and why the SUSBIO ECOTREAT IoT-enabled packaged STP stands out as the most advanced and future-ready solution for Goa’s unique landscape.
The Sewage Treatment Scenario in Goa
Current State: Infrastructure and Utilization
Despite its reputation as a developed state, Goa’s sewerage coverage is only 16%, significantly below the national average of 28%. Only Panaji, parts of Margao, and Vasco have proper sewerage systems, while most of the state relies on on-site sanitation or alternative technologies that often fall short of comprehensive treatment.
Goa’s urban population generates over 52 million liters per day (MLD) of sewage, but the existing 10 sewage treatment plants (STPs) with a combined capacity of 80.35 MLD are underutilized, with only about 70% of capacity being used. Utilization rates vary widely: some STPs like Shirvodem and Sancoale operate at or near full capacity, while others, such as Vasco and Durbhat, run far below their potential. This disparity highlights inefficiencies in collection networks, operational challenges, and the need for better planning and management.
Gaps and Delays
Several new STPs are proposed or under construction, but many face delays due to land acquisition issues, incomplete sewer networks, or bureaucratic hurdles. For example, the Undir-Bandora and Curti plants have significant portions of their networks ready but await commissioning, while others like the Curchorem plant are stalled despite land being procured.
Alternative Technologies and Their Limitations
In areas without sewerage networks, alternative technologies such as septic tanks or small-scale treatment systems are used. However, these often fail to meet environmental standards, leading to groundwater contamination and pollution of rivers and coastal waters.
Why Sewage Treatment Is Critical for Goa
Protecting Water Resources and Public Health
Goa’s rivers, estuaries, and groundwater are under constant threat from untreated or poorly treated sewage. This not only endangers drinking water supplies but also increases the risk of waterborne diseases, especially in densely populated or tourist-heavy areas.Safeguarding Tourism and the Local Economy
Tourism is the backbone of Goa’s economy. Polluted beaches, rivers, and backwaters can deter tourists, harm the state’s image, and result in economic losses. Clean water is also essential for the hospitality industry, agriculture, and fisheries.Meeting Regulatory and Environmental Standards
The Goa State Pollution Control Board (GSPCB) enforces strict effluent standards for STPs, including limits on BOD, COD, TSS, oil and grease, and fecal coliforms. Non-compliance can result in fines, legal action, or closure of facilities. With the Coastal Regulation Zone (CRZ) norms, discharge near sensitive coastal areas is even more tightly regulated.Enabling Water Reuse and Sustainability
With increasing stress on water resources, the state government has prepared an action plan to use treated wastewater for agriculture, forestry, toilet flushing, industry, and public utilities. Reusing treated water reduces the burden on freshwater sources, supports sustainable agriculture, and helps maintain green spaces.
The Limitations of Conventional Sewage Treatment in Goa
| Challenge | Impact in Goa |
|---|---|
|
Low Sewerage Coverage |
Only 16% coverage; most areas lack proper networks |
|
Underutilized Infrastructure |
Many STPs operate below capacity; inefficiencies |
|
Land and Space Constraints |
Urban and coastal areas have limited space for plants |
|
High Operational Costs |
Traditional STPs are energy- and labor-intensive |
|
Maintenance Complexity |
Skilled operators are scarce, leading to downtime |
|
Delays in Implementation |
Land, regulatory, and technical issues stall new plants |
|
Environmental Risks |
Poorly treated sewage pollutes water bodies and beaches |
Goa’s Regulatory Framework: High Standards, High Stakes
The GSPCB mandates that all STPs must:
Be designed for projected peak sewage loads
Use advanced treatment technologies (SBR, MBBR, MBR, etc.)
Include primary, secondary, and tertiary treatment, with disinfection (chlorination or UV)
Meet strict discharge norms: BOD ≤10 mg/L, COD ≤50 mg/L, TSS ≤10 mg/L, pH 6.5–9.0, and low fecal coliforms
Regularly monitor effluent quality and report to authorities
Manage sludge safely, preferably via composting or approved disposal
Non-compliance can result in heavy fines, operational suspension, or legal penalties.
