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
