Sewer Relining Project

Sewer Relining Project

The City is working with Insituform Technologies Ltd. to repair some of the heavily damaged sewer lines within the City using what is called No-Dig Technology. 

Advantages of No-Dig Technology:

• Rehabilitation of sewer lines utilizes Cured-In-Place Pipe Technology • Provides a full structural liner for the sewer • Reduces infiltration of ground water • Reduces exfiltration of sewage to the environment • Liner is designed for a 50 year Life span!

No-Dig technology has saved the Citizens of Melville hundreds of thousands of dollars annually! 


  • Traditional sewer main replacement and asphalting would cost approximately $685,000
  • The same No-Dig project would cost $115,000.
