Houston’s newest wastewater treatment facility was racing toward a commissioning deadline when crews discovered widespread moisture intrusion inside three miles of below‑grade chlorine‑dioxide distribution piping. Left unchecked, residual water threatened to corrode stainless linings, dilute disinfection potency, and stall the plant’s start‑up schedule. The prime contractor tapped John C. Digertt Inc. to engineer a rapid, non‑invasive remediation solution that could be mobilized immediately and completed without trenching or pipereplacement.
Pipeline Remediation
- Long Continuous Runs – Over 15,000 ft of 10‑in. and 12‑in. pipe left no room forsectional vacuum drying or pigging.
- Chemical‑Grade Cleanliness – Residual moisture or debris would compromisechlorine‑dioxide purity and downstream instrumentation.
- Zero Schedule Flex – The disinfection system had to be online before influenttesting—no grace‑period extensions.
- Confined Site Logistics – Active civil construction required minimal footprint and carefullycoordinated crane picks.
- Quick Mobilization –Dispatched a 20‑ft mobile desiccant‑drying trailer from our
Gulf‑Coast fleet and had boots on the ground within 24 hours of the request.
- Closed‑Loop Desiccant Drying –Installed temporary manifold headers at both ends of
each leg, circulating heated, moisture‑scrubbing air until internal dew pointreached
−40 °F.
- Inline Dew‑Point Monitoring –Placed portable hygrometers every 500 ft and logged
values to a cloud dashboard, giving the GC real‑time proof of progress.
- Corrosion‑Inhibitor Fogging –After drying, introduced a food‑grade volatile inhibitor to
coat the stainless interior and prevent flash rust during standby.
- Collaborative Scheduling –Sequenced pipe segments around concrete pours and
electrical work so every trade stayed productive and the critical path stayed intact.
