how deep? If quite deep, would the relocation be to a shallower line? It may be cheaper to abandon the existing line and put a new one in thandig down and encase. Pm me with a sketch and i can have a closer look plus get some rough costs
I have been provided quotes of $20-25k to relocate a sewer line in Gladstone to give you a ballpark cost figure. I understand the council don't approve of encasing them there.
