Elevated Storage Tank Repainting

Muhlenberg Township Authority

Muhlenberg, Berks County, PA

After more than 47 years, Muhlenberg Township Authority initiated the enhancement of their townscape by revamping the familiar 1.0 MGAL elevated water storage tank located on Tuckerton Road.

Spotts, Stevens and McCoy was chosen to provide consulting services to the skyscraping structure and its accessories, which were untouched since its original construction in 1971.  The project included preparing bid specifications to publically bid the project and obtain the necessary PADEP permits to paint the interior of the tank. 

SSM assisted in coordinating proper removal, disposal, and repainting of the interior and exterior of the tank in the time requested to suit the Authority needs. SSM worked together with the Township, PADEP and the contractor to ensure all processes and material disposal met state, local and federal safety standards. During construction the tank was upgraded to meet OSHA standards.

Concept Design for Probable Maximum Flood

LAKE ONTELAUNE DAM | READING AREA WATER AUTHORITY

Lake Ontelaunee Dam, built mid-1920, has stood for over 90 years supplying drinking water to the City of Reading and surrounding areas. Pennsylvania Code (Chapter 105) now requires most dam owners to upgrade to new flood standards or breach their dams. 

SSM’s team of professional engineers (hydrologist, geotechnical and civil), geologists (geophysicist, structural and hydrogeological), surveyors, GIS technicians and construction specialists completed a Concept Design to fortify Lake Ontelaunee Dam to safely comply with design criteria for a Probable Maximum Flood (PMF).  The Concept Design was prepared for the Reading Area Water Authority in response to the PADEP – Division of Dam Safety’s requirements to bring Lake Ontelaunee Dam into compliance. 

The dam consists of a 544 foot uncontrolled ogee crest concrete spillway and a 2,890 foot earthen embankment section.  Under the PMF criteria, the earthen embankment will perform as an emergency spillway.  To fortify the embankment and prevent it from eroding away during a PMF event, its upstream face needs to be thickened and its downstream slope requires hardening with Roller Compacted Concrete (RCC).  However, prior to RCC installation, subsurface soils need to be stabilized to support the proposed overtopping engineering controls and subjected PMF forces.  In addition, the team addressed complications created by State Highway 73 which traverses the top of the dam with its guiderail system that raised the PMF.

In developing the most cost effective solution for the Authority, SSM evaluated several technologies and their subsequent costs or risks in addition to RCC including:  articulated concrete block, 1,000 linear feet of culvert beneath Route 73, dam height reduction, a parapet wall option and a hardened artificial turf like system. Stability analysis, geotechnical investigations, environmental assessments, underwater dam inspections, and geophysical and hydrogeological studies were included with the Design Concept.

Pidcock Creek Stone Bridge | prepared design plans and technical specifications for the construction requirements, including site excavation and backfill, grading, gabion installation, bridge deck repairs and paving, stormwater conveyance, and significant amount of masonry repairs.  

Repairs to Dam #1 | Prepared drawings and specifications. Repairs included the rebuilding of sections of the stone and concrete dam crest, the replacement of the valve on the outlet pipe, the removal of sediment deposited in the vicinity of the inlet gate; and stream bank stabilization.

Repairs to Canal Bridge | Prepared and submitted a Pa DEP General Permit #11, including the permit application and meetings with Pa DEP. Prepared design plans for the re-construction of the roadway and bridge including plan and profile designs and grading.

Heritage Trail | Coordinated with the Delaware and Lehigh Heritage Corridor and the Bowman’s Hill Wildflower Preserve to replace a stone trail to connect the Delaware Canal to the Thomson Neely Grist Mill. Conducted a topographical survey of the area and designed a conceptual alignment of the redesigned trail to meet ADA/ABA accessibility standards. The alignment of the revised design, situation behind the mill, also provided a lower impact on the historic significance on the site.

Wastewater Treatment, Collection and Management | Obtained the PA DEP NPDES permit renewal and provided recommendations for equipment/process rehabilitation and/or replacement required to resume operations and discharge at the Lower Park Wastewater Treatment Plant. Provided recommendations and cost estimates for repairs, replacement, and improvements.

Lumber Museum, Galeton PA | Sewage System Evaluation and Design | Evaluated alternative methods of wastewater disposal. The methods were (1) to collect the wastewater and treat on-site by equalization storage, septic tanks with effluent filter, followed by a drip irrigation method of soil absorption, including further filtration and distribution to woodland soils, and (2) collect the wastewater, and pump it to the Denton Hill facility located across U.S. Route 6, and Nine-Mile Run stream. SSM subsequently designed a drip irrigation wastewater system as an alternative to the inadequate system. The process involved land surveying, preparing drawings and specifications for the preliminary and final designs, securing permits, providing bidding assistance, and overseeing construction services.

Valley of Concentration | Well Replacement | SSM located well site located, coordinated well drilling activities with Upper Makefield Township Department of Code Enforcement and the well driller, collected hydrogeologic data during drilling, and collection and reporting of water level data collection for PA DEP permit application.
