As documented in these photos, during the late afternoon rain storm of Tuesday, August 22, 2017, two of Delmont Borough’s sanitary sewer manholes on the Trust property discharged contaminated effluent for several hours onto the property and into the streams feeding directly into the Beaver Run Reservoir. The discharges are the result of rainwater inflow and infiltration into the sewer system.
Based on the short period of time between the start of the rain event and the start of the discharges, the discharges appear to indicate direct inflows whereby rainwater from downspouts and other prohibited connections divert water directly into the sanitary sewer system—which is not designed or PA DEP permitted as a Combined Sewer System—as opposed to infiltration, which is associated with seepage of ground water into the collection system through loose pipe joints and fittings as well as compromised manhole stacks.
For at least the last two decades, having full and certain knowledge of these circumstances and their consequences, Delmont Borough has been unable or unwilling to undertake any meaningful effort or substantive action to identify and mitigate the source and effects of the inflows and any infiltration. Through this same time period, the PA DEP has been aware of the issue and has provided no meaningful enforcement of the laws under its purview nor has it mandated a substantive corrective action plan regarding the Borough’s habitual assaults on the environment and on the community’s local drinking water source.
