What is CIPP?

2021 marks the 50th anniversary — the birth of the first cured-in-place process for sewer rehab, simply known as CIPP. The CIPP pioneer, Eric Wood, impregnated a felt tube with polyester resin, wrapped it in a plastic sheet, dragged it 230 ft into the 12-in., egg-shaped, brick sewer and inflated it with air. Then left it to cure.

A pipe was given a new life for at least the next 50-plus years.

The 2021 trenchless market reaches into the billions, with more work on sewers lines needed every day as they continue to age and decay. Diameters and lengths are the largest and longest they have ever been, with diameters exceeding more than 120 in. in some projects. Technology and research continue to hum along.
