Stormwater and groundwater that enter commercial sanitary sewer and process piping through cracked joints, failed seals, and deteriorated manholes add volume to systems designed for wastewater only — increasing treatment costs, overwhelming pump capacity, and causing compliance problems during wet weather events.

Inflow and infiltration enter commercial pipe systems through specific structural failure points — most of which are identifiable and addressable through trenchless rehabilitation.
Inflow and infiltration assessment uses CCTV camera inspection under wet conditions to identify the precise locations where water is entering the system.
Inflow and infiltration problems are most severe in older commercial systems where joint seals have aged past their design life and manhole infrastructure has deteriorated.
A Greensboro office park with a private sanitary sewer collection system was experiencing wet-weather surcharging during rain events — causing backup risk at the lowest-elevation building. Flow monitoring over 30 days confirmed infiltration volumes were running 3.2x the dry-weather baseline during and after significant rain events.
Camera inspection identified joint failure across approximately 60% of the collection system's pipe length. LiningWorks installed CIPP liners through all identified defect segments in a single mobilization. Post-rehabilitation flow monitoring over the following 30 days confirmed an 82% reduction in wet-weather infiltration volume.
“We'd been managing wet-weather surcharging for years. LiningWorks scoped the whole system, lined the bad segments, and our flow monitoring showed an 82% reduction in infiltration. No backup events in the 18 months since installation.”

Inflow and infiltration rehabilitation requires accurate source identification before rehabilitation scope development. LiningWorks camera-first approach ensures the rehabilitation addresses the actual infiltration sources.
Camera inspection first — we identify and document all infiltration sources before developing the rehabilitation scope.
336-477-3218, Mon–Sat 7AM–6PM. Wet-weather surcharging, elevated flow volumes, backup events during rain — describe what the system is doing and when, and we'll schedule the right assessment approach.
We scope the system under wet-weather conditions to identify active infiltration sources, develop a prioritized rehabilitation scope, and establish a pre-rehabilitation flow monitoring baseline.
CIPP lining seals all identified infiltration sources in a single mobilization. Post-rehabilitation flow monitoring confirms volume reduction and provides documentation for property records.
