VEI has experience with all phases of wastewater projects, including feasibility studies, planning and design of collection systems, I/I studies and system rehabilitation, treatment plants and disposal systems. 

 

Our work has involved facilities for large communities as well as on-site systems for remote lodges and private clients.  VEI routinely properties environmental documents and obtains permitting for projects. Environmental documents include Categorical Exclusion, Environmental Assessments, and VEI prepared the EIS for the proposed Kenai River crossing at Scout Lake Road.

FEATURED PROJECTS

Kodiak Wastewater Treatment Plant Upgrade - VEI designed upgrades to this 4 MGD secondary treatment plant, incorporating many of the recommendations from the Sewer Study (prepared by VEI).  The $11 million budget covered d esign and construction of two additional 0.3 MG clarifiers, a new aeration system, and a sludge treatment system for landfill disposal.  VEI provided civil and sanitary design and coordinated the work of 5 separate subconsultants.  We also worked with the Kodiak Island Borough to develop and implement dewatering and lime treatment processes to condition the sludge for disposal to the local landfill in accordance with State regulations.

Eagle River Sewer Trunk TID ER-3 - VEI provided design and managed constructionof this 8,000-foot sewer trunk extension project which included a 1 MGD pump station, standby power and an underwater pipe crossing of Eagle River..  This project provided sewer service to an existing correctional facility, a recreational campground, a residential subdivision and the new Eagle River High School. Extensive agency coordination was required for the permitting of the pipe crossing beneath Eagle River.

Pump Station 10 Infiltratio/Inflow Study and Pump Station Upgrade - VEI provided flow monitoring and sewer inspections to determine the condition of the sanitary sewer collection system in the Turnagain area of Anchorage. Services included a complete manhole and sewer inspection and flow monitoring. VEI designed the follow-on improvements to the sewer system, including a new pump station.

Pump Station 20 Rehabilitation - VEI designed upgrades to bring this facility up to code and replace aging components.  Work included design of a temporary bypass system to accommodate wastewater flows during construction at a challenging location under the residential roadway of Sandy Beach Drive in Anchorage.

Agulowak River Retreat On-Site Water/Sewer Improvements - Improvements involved an evaluation of water and wastewater facilities at a remote corporate retreat lodge owned by GCI near the Tikchik Lakes north of Dillingham.  Following evaluation VEI performed a site survey, soils investigation, and facilities inventory.  We then designed a STEP wastewater system using a gravelless bed with infiltration and a new Class C public well.  Logistics were challenging, since normal access was by floatplane and/or shallow draft boat.

Chester Creek Improvement Study

 VEI Consultants - Alaska Civil and Environmental Engineering, Transportation, Water, Wastewater, Surveying Services

In the early 1980s VEI was tasked with evaluating the water quality of Chester Creek, an urban stream that flows through Anchorage.  The study entailed selective sampling of creek water to identify pollution sources, recommending and prioritizing stream clean-up efforts and channel improvements, along with preparing cost estimates.  Other work included investigating sediment transport and fecal coliform levels, with the eventual goal of restoring the fishery along Chester Creek. VEI’s continuing work on Chester Creek has included an Oil and Grit Separator at C-Street, and Fish Passage Culvert Design.

 

Otis Lake & Baxter Bog Stormwater Treatment

VEI was selected by the Municipality of Anchorage Department of Public Works to design miscellaneous oil/grit separators in the Anchorage area. The Otis Lake & Baxter Bog projects involved design of a constructed wetland at Otis Lake and a vault at Baxter Bog with overflow into the bog.   VEI gathered data on sediment loading of storm water at these locations, which led to design of these natural treatment methods.  Baxter Bog included a small concrete skimming vault, then installation of a timber weir in a 150-foot long man made ditch.
