(Summit Consulting did not participate in the initial project estimate, mobilization, and procurement activities.) The Cowater Flush Tank and Haul System provides individual sanitary sewer and piped water systems (from a storage tank) to communities that cannot install conventional piped sewer and water systems due to unfavorable site conditions or lack of the economic base necessary to support the operation and maintenance costs. Low water use toilets and water and sewage holding tanks were installed at each residence after demolition and disposal of the preexisting fixture. Close coordination and scheduling with each homeowner by the superintendent allowed the crews to carry out the installations without excessive inconvenience to the homeowner. Following project completion, Summit Consulting performed a detailed cost analysis with resulting data used by Cowater to accurately estimate new work.

The first study focuses on water and sewer topics and develops a plan for a new washeteria and improvements to the school's wastewater system. The second study is directed toward solid waste management. The existing unpermitted dump sites were investigated and a series of alternatives for a new landfill were developed. After the community selects their preferred alternatives, preliminary design will be developed, including site plans, aerial photography, cross sections, access roads, and utility management.

The feasibility study examined options for construction of a potable water transmission main from the new wells at the base of Razorback Ridge to the existing water treatment plant. Two primary systems were considered: Fill and Draw and Continuous Operation. Summit determined that the surface Fill and Draw system was less costly to construct, operate, and maintain. Construction for the Razorback Water Transmission Line began during 2008. A well house, power line extension, and transmission line with heat trace and protection was constructed. During the 2009 construction season Summit will return to Wales to finalize the operation of the transmission main, complete the O&M manual, train local operators on the filling of their water storage tank and to demobilize the project.

Wales Water Tank Rehabilitation
2004

Summit Consulting performed patch repairs, interior tank coating repairs, and replaced nozzles to the water storage tank in 2004. Also in 2004, Summit Consulting drained, disinfected and repainted the water storage tank interior with a Devoe AWWA approved coating system. The project included repairing and replacing the existing piping, valves, manway and related appurtenances. The water storage tank was returned to service in 2004.


Wiseman
2004

Located on the southern slope of the Brooks Range in northern Alaska, Wiseman was home to early 20th century prospectors during Alaska's gold rush. One of the few remaining historic structures in Wiseman is a log building that originally served as the miners' community hall. The structure was built directly on the ground and over the past century, the lower log courses have decayed. After inspecting the building, Summit developed a plan to raise the entire structure and construct a new foundation below it. The construction was complicated by Wiseman's remote location: above the Arctic Circle and over 250 miles from the nearest hardware store. Summit procured and mobilized new materials, the rotted logs were replaced, and the building was lowered onto a treated timber pony wall foundation.
