Storm drain cleaning and jetting restores design capacity by clearing everything inside the pipe.

WHAT JETTING REMOVES

What accumulates inside storm drain pipes — and what hydro jetting does to it.

Storm drain pipes accumulate sediment from every storm event — sand, gravel, and silt deposited in low-velocity sections where settling occurs. Over years, sediment accumulation reduces pipe cross-section significantly below design capacity.

Leaf debris, organic material, and root masses create additional flow restrictions — particularly at joint locations where root intrusion provides a collection point for organic debris.

High-pressure hydro jetting (2,000–4,000 PSI) dislodges and flushes all accumulated sediment, organic debris, and root masses downstream to the next access point or retrieval point — restoring the full pipe cross-section to near-design condition.

CAMERA BEFORE JETTING

Why camera inspection before jetting changes the cleaning scope.

Camera inspection before jetting identifies whether capacity loss is caused by sediment only — or by structural failure that requires rehabilitation after cleaning.

• Camera identifies structural defects that jetting alone cannot address

  If camera inspection finds structural collapse, significant root intrusion, or joint failure in addition to sediment, jetting alone will restore temporary capacity — but structural rehabilitation is needed for a permanent solution.
• Camera confirms sediment depth and distribution for accurate jetting scope

  Knowing where sediment is heaviest allows jetting effort to be concentrated where it's most needed — reducing jetting time and confirming the cleaning scope before work begins.
• Camera provides documentation for property maintenance records

  Pre-jetting camera footage documents pipe conditions before cleaning — providing an objective baseline for the property maintenance record and for post-cleaning comparison.

BEFORE & AFTER

Retail center storm drain — 12 years of sediment accumulation cleared in one day.

A Greensboro retail center had not had its main storm drain system professionally cleaned since the property was constructed 12 years prior. Camera inspection showed sediment filling 40–60% of the pipe cross-section in multiple sections — with the worst accumulation near the downgradient end of the system.

LiningWorks hydro-jetted the full system in a single day through existing curb inlet and manhole access. Post-jetting camera confirmed full pipe cross-section restoration throughout. Camera also identified two sections with minor joint separation that were flagged for CIPP lining in a follow-on mobilization.
