A+E has extensive wastewater experience that ranges from small de-centralized wastewater systems to MM gallon wastewater treatment facilities. In fact, we have provided preliminary engineering, design and construction engineering services for the upgrade and/or expansion of 20 different wastewater treatment facilities and 30 different wastewater collection systems since 1995. Taking each project from concept to commissioning provides us with unrivaled knowledge of wastewater collection, transmission and treatment.

WASTEWATER ENGINEERING PROEJCTS
Village of Essex Jct., VT - Aldrich + Elliott is currently providing the construction engineering services for the Village of Essex Junction Wastewater Treatment Facility Upgrade Project. The Village is providing periodic updates and pictures via their website that you are encouraged to view at the following link: Village of Essex Junction Wastewater Treatment Facility.
Springfield, VT - Upgrade and expansion of a conventional activated sludge (CAS) wastewater treatment facility from 2.2 mgd to 2.4 mgd on a very tight site while maintaining process operations was required. The upgrade included two new primary clarifiers, two refurbished secondary clarifiers, a new secondary clarifier, septage receiving with screening, new headworks, anaerobic selector, aeration tank improvements, anaerobic sludge digestion upgrades, methane gas conversion, UV disinfection, new gravity belt thickener, belt filter press refurbishment and supervisory automated controls (SCAD). An anaerobic selector was provided to optimize biological phosphours removal, to reduce chemical use.
Milton, VT - Converting a 225,000 gpd aerated lagoon WWTF, to a 1.0 mgd Sequential Batch Reactor (SBR) WWTF, with new headworks, septage receiving with screening and sludge dewatering was the goal. Phasing of this project was complex as the WWTF operated on ¾ of their lagoon capacity for twelve months as the SBR basins, new headworks and UV disinfection were constructed and placed into service. This upgrade included supervisory automated controls (SCADA) to fully automate systems and report alarm conditions, as well as the design and construction of pump station improvements and new construction.
“The staff’s knowledge of wastewater treatment plants and sewer systems were invaluable to our project. Every milestone was delivered on time and within budget. In all presentations the professionalism, knowledge and understanding allowed them to effectively address concerns and answer questions in a way that instilled confidence.” – Terry Morse, Bennington Water Resources Superintendent
