Water Quality Vault Cleaning

What This Service Involves

Underground water quality vaults, including media filters and oil-water separators, capture pollutants that must be removed before they overload the system. Our crews perform the confined-space entry, vactor removal, and media servicing these structures require under OSHA and manufacturer protocols. We measure sediment and oil accumulation against maintenance thresholds in your stormwater manual. All removed material is manifested and disposed of at approved facilities.

Benefits

Confined-space work performed under OSHA-compliant protocols; restored treatment capacity of vaults and separators; accumulation measured against manual thresholds; manifested disposal of oily and contaminated waste; documentation ready for permit reporting

Our Process

1) Set confined-space entry controls and safety monitoring; 2) Vactor out sediment, oil, and spent material; 3) Service or replace filter media per manufacturer spec; 4) Manifest waste and document the vault's condition

What Affects the Cost

Vault type, depth, and media system; confined-space entry requirements; volume and contamination of removed material; disposal and manifesting fees; traffic control for in-street access

Best Time of Year

Vault servicing is scheduled before the wet season and again mid-winter for high-load sites that fill quickly during sustained rain.
