Denison University Point Repair and CIPP

Founded in 1831, and Ohio's second-oldest liberal arts college, Denison University is a private, coeducational, and residential four-year liberal arts college in Granville, Ohio. Denison is situated on 931 acres of rolling Ohio hills with a 350 acre Biological Reserve and the historic Denison Golf Club. After discovering two issues in their existing pipes, Denison University utilized a certified Flow-Liner Installer's versatility in rehabilitation systems by using a Flow-Liner Point Repair system and Flow-Liner CIPP. The Point Repair system successfully sealed small pin hole leaks with the use of a stainless steel sleeve. A 120' section was lined with CIPP, successfully navigating four 45 degree bends. Facilities Services was very pleased with the timeliness of the two repairs.


Trenchless Potable Pipe Lining

The NSF 61 approved Neofit®+Plus Potable Pipe Lining System is a non-invasive option for leaking underground water services with inside diameters from 1⁄2" to 2". The Neofit®+ liner forms a continuous barrier between the existing pipe and drinking water in up to 300ft sections in any type of pipe, including copper and lead.

A homeowner from Pittsburgh, PA contacted a Certified Flow-Liner installer in hopes to find a non-invasive way to rehabilitate the existing water service line that was found to have dangerously high lead content.This particular water line was over 150ft long and at a 35ft decline to the curb stop. The traditional dig and replace method would have required a lot of excavation, but also a lot of demolition to the foundation and existing concrete structures on the property.With minimal disruption, the Certified Neofit®+ installer successfully lined the existing lead service line, making the homeowner's potable water safe for drinking (and showering) again.

"Your expert Neofit®+ lining installation has made an unlivable building back into a house.Before the lining, the lead was so high that even showering was not recommended. Now, the water is drinkable. (So say the lead tests --and it tastes great!) Given the long lot, the slope, the curving path of the pipe, the proximity to sewer and gas lines, the multiple step walls (and the resulting shallow and deep spots), I'm so very glad you could line the existing pipe. Digging it would have been a logistical nightmare. Another big plus: not having to disturb the old foundation in any way. I hope Pittsburgh and surrounding municipalities turn to Neofit®+ as a default option in dealing with our many lead service lines, and also with mains in need of lining. I wish you much success and many more jobs. I would recommend the Neofit®+ process with great pleasure to anyone." — Satisfied Customer in Pittsburgh, PA
