In a new white paper, Sewer Rehab: Deciding Between Spot Repair and End-to-End, we discuss these considerations in detail, giving you a framework for making rehab decisions that make the best use of your available resources.
One consideration is type of damage. Not every defect is structural. Sometimes, ‘gushers’ (instances of major infiltration) originate from a single crack, hole or joint, in which case end-to-end relining may not be warranted. Instead, a simple solution like mechanical spot repair can eliminate the infiltration at a fraction of the cost and with far less disruption. And, in the case of a localized structural defect, mechanical point repair can also provide a cost-effective solution.
Contractor preference is another factor that impacts whether spot repair or end-to-end is used. Many contractors advocate for end-to-end repair, even when spot repair would be more effective and affordable, simple because that’s what they’re equipped for and what they’re most comfortable with. In these situations, municipalities can ensure access to both options by specifying each in their contracts.
