Aldrich + Elliott has provided wastewater system engineering for more than 50 different Vermont municipal or large commercial wastewater systems, since 1995! No one can offer more municipal wastewater collection, pumping and treatment experience in Vermont over the last dozen years than A+E.
Our wastewater experience ranges from small de-centralized wastewater systems to some of the largest wastewater treatment facilities in Vermont. 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.

Springfield, VTUpgrade
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. |
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.” -
