text: In 1971, Eric Wood implemented the first cured-in-place pipe technology in London, England. He called the CIPP process insitu form, derived from the Latin meaning "form in place". Wood applied for U.S. patent no. 4009063 on January 29, 1975. The patent was granted February 22, 1977, and was commercialized by Insituform Technologies until it entered the public domain on February 22, 1994.
