Water Track (Morning)
Rigid & Flexible Buried Piping Systems
Richard Hill. P.E., Ranker Materials, Oakdale, PA
Reliable roadways and sound infrastructure has been essential to every major civilization since before the Roman Empire. To build a society, progress was dependent on the control of water and wastewater. Now more than ever before, it is important to understand the principles influencing the design and installation of the many types of piping material options available today. Different standards apply to rigid and flexible piping materials affecting how they are designed, installed, and inspected to ensure the expected design life. This presentation will cover; the design principles for both rigid and flexible pipe, the manufacturing process of reinforced concrete pipe, direct (PennDOT) & indirect design methods for reinforced concrete pipe, post installation inspection methods to verify proper installation.
Comprehensive Approach to Stormwater Runoff Management
John R Smith, Corporate Environmental Solutions, LLC, Pittsburgh, PA
To comply with increasing regulations per section 303(d) of the Clean Water Act, focused on reducing Total Maximum Daily Loads (TMDL) for impaired waters, point discharges of stormwater runoff from commercial and industrial facilities are now being regulated for site-specific pollutants. The focus of this course is to present three different, yet complimentary processes, for efficiently complying with such permitted discharges. The three processes are:
- stormwater runoff reduction via greening of areas;
- stormwater collection and temporary storage; and
- low cost passive treatment of collected stormwater.
A model approach focused on minimizing the overall cost of compliance, via the optimal combination of the three different processes will also be presented.
The “Gray Area” of Green – Dellrose Street Case Study
Jason Borne, P.E., ms consultants, inc., Coraopolis, PA
Stormwater management programs are traditionally tied to maintaining public safety, mitigating private land development, or addressing CSO consent orders. Not surprisingly, other opportunities to integrate green stormwater infrastructure into urban reconstruction seldom come to fruition, falling victim to a “gray area” in stormwater policy.
The Dellrose Street project broke new ground as the first full-width street reconstruction project using permeable pavers in the City of Pittsburgh. This innovative street design allowed for the preclusion of traditional storm sewer infrastructure while providing flow reduction and aesthetic benefits not typically available to traditional reconstruction projects. Established in the public right-of-way and located within the tributary area of a combined sewer system, this commonly-performed public works activity presented an often untapped opportunity to address the stormwater concerns of multiple stakeholders.
GIS Applications for Water, Wastewater, and Stormwater systems
Sam Shamsi, Jacobs Engineering Group Inc., Pittsburgh, PA
More than 80 percent of all the information used by water, wastewater, and stormwater utilities is geographically referenced. While GIS applications for water, wastewater, and stormwater systems are not new, getting beyond the basic inventory and mapping functions is often challenging. Unless a utility GIS is taken to the operational level, it’s just a pretty map. That is why, GIS emphasis is now shifting from computerized mapping to enterprise-wide mission critical applications. This seminar will focus on the four Ms that are of particular importance to water, wastewater, and stormwater systems: Mapping, Monitoring, Modeling, and Maintenance.
- Define the components, functions, and types of GIS.
- Discover the meaning and power of GIS applications for water, wastewater, and stormwater systems.
- Identify examples of GIS applications in mapping, monitoring, modeling, and maintenance.
ABC Decking of DELDOT BR 1-717, I-95 NB over SR1
Jonathan Eberle, AECOM, Mechanicsburg, PA
This presentation presents the design and construction undertaken for the replacement of the existing I-95 NB bridge deck using accelerated bridge construction (ABC) technologies. The bridge carries I-95 NB over a high-volume principal arterial roadway and consists of four simple spans (32’-70’-70’-36’) on a nearly tangent alignment having a 35 degree skew. The existing c.i.p. concrete deck is composite and supported on rolled steel beams. The steel beams and the substructure units were reused as part of this bridge rehabilitation project. Preliminary engineering considered a variety of ABC technologies and after careful consideration, full-depth precast concrete deck panels with UHPC longitudinal and transverse deck joint details, expansion joints at piers/abutments and a polyester polymer concrete (PPC) overlay was selected for reasons to be explained. Replacement of the bridge deck required two stages of construction to accommodate the high traffic volume.
