INNOVATION July-August 2012

RiverviewCreek Channel and Floodplain Enhancements Nova Pacific Environmental supervision of channel and floodplain enhancements on Riverview Hospital lands in Coquitlam, BC, referred to as “Riverview Creek.” The purpose of the project was to combine hydrological engineering with retained LaCas Consultants for the design and construction

biology in order to enhance the fisheries habitat, reduce

scour/erosion and increase floodplain utilization. Channel enhancements included the design and installation of two new fisheries channels connected to a pond. Hydrological and hydraulic modeling was carried out to determine the water surface profiles in the channels and the pond. The new channel/pond system will be connected to Riverview Creek during the 2012 fisheries window. Project participants: Brian LaCas PEng (LaCas Consultants), Bruce Wright RPBio (Nova Pacific Environmental).

City of Port CoquitlamBroadway Street Reconstruction

This advanced wastewater treatment plant serves the new Falmouth, Jamaica, Cruise Port. The plant is located within walking distance of the shops and terminal, making visual impact, odour and noise of utmost importance. The plant is designed to treat an average daily wastewater flow of 530 m 3 /d. The flow enters the plant from the Cruise Port over approximately eight hours so a well-sized equalization tank was therefore provided. The plant features two ECOfluid USBF ® bioreactors designed to produce effluent of BOD/TSS < 10 mg/l, Total Nitrogen < 10 mg/l and Total Phosphorus < 3 mg/l. Sludge drying beds were utilized for biosolids management. Owner: The Port Authority of Jamaica. General contractor: YP Seaton & Associates Company. Process/mechanical engineering: ECOfluid Systems (Karel Galland PEng, Brian Chan PEng). Electrical engineering: A Ho Enterprises (Ayton Ho PEng). Structural engineering: JR MacKenzie PEng StructEng. Broadway Street is a key 1.2 km industrial arterial roadway that connects Mary Hill Bypass to the Coast Meridian overpass. The reconstruction project consists of widening Broadway Street from a two-lane road to full arterial cross-section complete with four travel lanes, a centre turning lane, designated bicycle lanes and separated sidewalks to provide significantly improved traffic access and flow locally and throughout the region. The project also incorporated a number of utility improvements: large concrete box culverts provided improved drainage conveyance and boulevard bioswales were introduced to process rain water from the road surface prior to discharging to the storm sewer system. Trenchless pipe-lining technology was employed to upgrade a significant portion of the existing sanitary sewers. LED street lighting luminaries replaced traditional high-pressure sodium units to provide longevity and energy efficiency. CitiWest Consulting was the lead consultant for this project.
