Scorpion Bay Wastewater Treatment Facility

The new Scorpion Bay Marina is located on the west coast of Lake Pleasant.  The marina includes more than 300 boat slips, a boat pumping station, restrooms, showers, and a restaurant.  GHD provided permitting, design, and construction services for the marina’s wastewater treatment plant.  The plant is an activated sludge facility with extended aeration and de-nitrification capability.  It also includes sand filtration, chlorination and de-chlorination, and an aerobic sludge digester.  All of the reclaimed water produced by the plant is stored in an above-ground steel reservoir and pumped through the marina’s irrigation system. 

To enable the marina to open prior to the completion of the treatment plant, GHD also designed a temporary vault and haul system that included instrumentation and controls, secondary containment, an aeration system and an odor control air scrubber.  In addition, GHD provided design and construction support for the marina’s wastewater pumping system, which uses peristaltic pumps to move flows from boats, restrooms, and the restaurant to a common wet well where they are then pumped using grinder pumps off of the marina and to the treatment facility.

Because all wastewaters are different, it is necessary to work with a team that can combine comprehensive knowledge with practical experience in the fields of chemistry, biology, hydraulics, mechanical processes/equipment, instrumentation and control, materials handling and plant layout.

GHD can deliver on all the process components that make up a wastewater treatment plant. We have designed and project managed more than 300 wastewater treatment plants (including major municipal facilities processing 500Ml a day and industrial projects).
