CiPPi (Cured In Place Pipe Intelligence)

The Process:  Throughout the US, thousands of miles of sanitary and storm sewer lines are in need of rehabilitation. The process monitoring of a Cured-in-Place-Pipe lining for sewer rehabilitation is typically a manual process, whereby a resin-saturated coated felt tube is inserted into a damaged pipe from Station A to Station B (typically manholes). Hot water, steam or Ultra Violet Light is used to cure the resin and form a tight fitting replacement pipe, inside the original pipe. Cure temperature is controlled at the A station and fluctuates between cold to steam/hot water and back to cooling temperatures. Temperature readings taken at the A-station and B-station are typically recorded in a log every three (3) minutes. The B-station individual also communicates the readings back to the A-station.

The Problem:  Currently, temperature readings are taken only at the entry (A-station) and exit (B-station) manholes. To ensure proper and complete curing, it is best to know the temperature between the liner and the host pipe, for the complete length of the host pipe.

The Solution:  CiPPi - Zia has developed sensors that will capture temperature readings all along the host pipe as the resin-based liner is cured. Temperature readings are taken at predetermined intervals, in real-time, and sent to an on-site computer. The temperature readings can also be monitored via a smart-phone app. The data will also be uploaded to a web-server for aggregation and customer reporting. How do we do it? Please see the video below:

The Benefit: Knowledge of the efficiency of the curing process is important in order to provide confidence to installers and customers. The sensor data transmitted to operators at the job site helps improve process control and Quality Assurance. And knowing the temperature all along the pipeline will help reduce the risk of curing failure, and reduce cost.
