The Borough of Harvey’s Lake, Pennsylvania has a rich history dating back to its discovery during the Revolutionary War. The majesty of the 660 acre glacial lake is an undeniable sight but since the Borough’s founding in 1968, a green tide crept in to threaten the lake-wide ecosystem. As the Borough has grown, an increased amount of pollution has sullied the lake from contaminated stormwater runoff carrying a non point source nutrient pollutant load heavy in nitrogen and phosphorus. High nutrient levels heavy in phosphorus can lead to frequent algae blooms. Studies conducted by the PA Department of Environmental Protection show that a 10% increase in phosphorus levels leads to a 50% increased chance in causing a eutrophic state.
In an attempt to correct this issue, Borough officials installed a new sewer system around the lake which vastly improved water quality but only hindered the frequency of algae blooms. They still plagued the lake periodically and in 2014 a dangerous new threat, the invasive aquatic species hydrilla, appeared claiming large portions of the lake while also starving aquatic life of vital oxygen. Therefore, Borough officials implemented a multiphase water quality improvement plan starting with installing a Suntree Technologies Nutrient Separating Baffle Box® hydrodynamic separator at the lake boat launch in 2016. By utilizing the NSBB™ along with a newly established storm drain system, the health of the Harvey’s Lake ecosystem and lakeside residents will only continue to improve while also stunting the hydrilla invasion.
Planning for Pollution Prevention
Phase 1 of the Harvey’s Lake water quality improvement project broke ground in Decemeber 2016. The comprehensive project is based on a NPDES 319 project targeting the recreation area of Harvey’s Lake to improve water quality and prevent non point source pollution. The determination of the excavation area for the NSBB™ manufactured treatment device was coordinated through the Pennsylvania Fish & Boat Commission and Stormwater Solution Source. The area was selected due to its heavy public recreation use from boating enthusiasts, fishermen and swimmers. The Pennsylvania Fish & Boat Commission building incorporates a substantial parking lot where a vast amount of runoff directly impacts the lake from the heavily trafficked area. The NSBB™ installation went smoothly and is essential to flow treatment.
Boat Launch NSBB™ Diminishes Algae Growth
The direct treatment of stormwater emptying at the Pennsylvania Fish & Boat Commission boat launch is now filtered via an NSBB™ which was installed on December, 14 2016. Developed by Suntree Technologies Inc®, the NSBB™ is a hydrodynamic separator which specializes in online sediment capture without the typical headloss and sediment scouring. Its patented lidded screens prevent nutrient leaching and static water from turning septic due to prolonged contact with trash and debris. It also includes a SkimBoss® floating skimmer to prevent debris from passing through the vault during high flows and a StormBoom™ that absorbs hydrocarbons.
Prior to delivery, Suntree Technologies Inc® Personnel were on site at an Oldcastle Precast Concrete facility to install the NSBB™ internal components including the turbulence deflectors and basket stabilization components. The treatment unit does not require confined space entry, saving time, effort and a great deal in upkeep costs. The delivery and installation of the vault structure took only a day to complete as a joint effort between Machiesky Construction, Princeton Hydro LLC, Oldcastle Precast Concrete, Stormwater Solutions Source (S3) and Suntree Technologies. The Harvey’s Lake NSBB™ unit vastly improves the water quality of runoff flowing in the system and prevents pollution of hydrocarbons, trash and sediment and minimizes nutrients from reaching the lake. Harvey’s Lake is committed to water quality improvement and to eradicating the giant Hydrilla and algae growth threatening the ecosystem. This proactive effort will ensure a decline in invasive species growth and an overall increase in community health.
