Basic Sewer Line Extension
The cost of connecting to an existing municipal or industrial sewer system depends on the distance from the main line and pipe diameter.
- Typical cost ranges from ₹1,500 to ₹3,000 per running meter
- For a 100-meter extension, the cost may be ₹1.5 lakh to ₹3 lakh
- Includes excavation, pipe laying, backfilling, and basic approvals
Site-Specific Factors
Costs vary based on terrain, soil condition, pipe depth, and requirement for manholes or lift stations.
- Rocky or waterlogged soil increases excavation and labor costs
- Deeper trenches or sloped terrain require reinforced works
- Manholes and inspection chambers add ₹10,000 to ₹25,000 each
Additional Systems and Treatment
Some industrial users require pre-treatment or standalone waste management systems before connecting to public sewer lines.
- Septic tank systems: ₹1 lakh to ₹2 lakh for small units
- Effluent treatment plant (ETP): ₹5 lakh and above, depending on discharge type
- Government approvals may add time and regulatory fees
