Our Projects

Solid Waste Resource Management

Landfill Development, Closure, Operations/Maintenance Engineering

Olympic View

Olympic View Sanitary Landfill Engineering Design and Construction Management Services

This landfill abuts wetlands and subsoils can liquefy. VIKEK has provided assessment of landfill components, design of cover systems, landfill gas and condensate piping, leachate system evaluation and construction that includes collection, pumping, force main and lagoon.

Read More
Stormwater collection and storage assessment and designs have been completed. Permitting and negotiations with regulatory agencies to achieve owner goals are provided for each project. Recent tasks have been to assess the leachate system that includes alternative assessment of leachate lagoon upgrades, management of geotechnical subconsultant, leak testing plan for leachate force main, replacement of leachate pumps and negotiations with Ecology Dam Safety Office (DSO), Kitsap County Emergency Management. Negotiations have led to DSO considering allowing an operation variance that limits quantity of leachate stored below the anticipated settlement following the design earthquake event. The variance will save the owner significant cost.
