From 2013 to 2022, Sci-Tek assessed and inspected stormwater management systems throughout Philadelphia as a subconsultant to Johnson, Mirmiran & Thompson. The Philadelphia Water Department (PWD) implemented the stormwater management regulations to address a variety of water resource concerns including enhancing water quality, decreasing stormwater runoff and flooding frequencies, and protecting impaired streambanks and channels. A significant percentage of the stormwater goals depend on the compliance of private development projects with these regulations.
The scope of work for the project required implementing non-destructive inspections and assessments of approximately 500 sites and their constructed stormwater management facilities with minimal disturbance to site operations and private infrastructure including inspection planning, site inspections and performance assessments, observation reporting, as-built red-line plan mark up, and compliance reports. The stormwater management features and drainage components associated with these sites included:
- Sub-surface infiltration and detention
- Bio-infiltration/Bio-retention
- Green roofs
- Porous pavement systems (pavement, pavers, concrete)
- Manufactured water quality devices (hydrodynamic separators or other equivalent)
- Stormwater reuse systems (cisterns, irrigation)
- Site drainage & pre-treatment (inlets, trench drains, yard drains, or equivalent)
- Basin control structures (outlets, weir walls, slow release controls, level spreaders, or similar)
PROJECT FEATURES
- Required as part of PWD’s compliance agreements with PADEP.
- Ensures that privately installed SMPs are being maintained in accordance with the approved post construction stormwater management plan.
