I
am a project design and construction engineer with background
in municipal treatment plants. I have been involved in process/design
work and construction management services for small and large-sized
municipal plants. With Stearns & Wheler, I have performed
process/design work and construction management for treatment
plant upgrades.

My relevant experience
at Stearns & Wheler and from previous research include the following:
Municipal
- Construction
services engineer for a Stearns & Wheler BNR and Odor Control
Upgrade design of the 8.1 MGD Cambridge WWTP in Dorchester County,
Maryland.

Modifications include headworks modifications, aeration tank modifications,
aeration system modifications, new flow distribution boxes, new final
clarifiers, existing final clarifier modifications, sludge pumping
modifications, sludge thickener modifications, shellfish protection
pond sludge removal, new chemical feed facility, new biofilter, new
biofilter blower building, underground piping, electrical modifications,
and process control system. Responsibilities include shop drawing
and RFI review, field inquiries, coordination of progress meetings,
and change order negotiation.
- Construction
services engineer for a Stearns & Wheler Odor Control Upgrade
design at the Annapolis WRF in Anne Arundel County, Maryland. Modifications
include installation of odor control piping, covering two primary
clarifiers and four gravity thickeners, expanding the primary effluent
distribution box, and installation of two odor control fans. Responsibilities
include shop drawing and RFI review, field inquiries, and change order
negotiation.
- Project engineer
for upgrade of 13 MGD Annapolis Facility Expansion. Responsibilities
for this project included design of a 3 million gallon Emergency Holding
Pond, and upgrade of the existing Influent Pumping Station. Included
within these responsibilities were hydraulic analysis, cost estimation,
specification preparation, and equipment sizing and selection.
- Project engineer
for the Glebe Heights Force Main and GH-1 Pump Station Upgrade. Responsibilities
for this project included design of a 0.6 MGD submersible pumping
station, layout of 6,300 feet of 10-inch HDPE force main, and cost
estimation.
Study for Selbyville
WTF in Sussex County, Delaware. The project included identifying a cost-effective
approach to expand the treatment capacity of the plant's average design
flow to 1.5 MGD, and to evaluate sludge managements options and potential
problems associated with I/I flows. Study responsibilities included
hydraulic analysis, facilities layout, and equipment selection.
Research
- Assisted in the
design and installation of two irrigation systems used for land application
of liquid waste.
- Assisted in the
installation of groundwater monitoring wells for land application
of waste research projects.
- Carried out laboratory
procedures to determine total solids, volatile solids, fixed solids,
and specific gravity of wastes.
- Conducted experiments
relating to gravity settling, sand filtration, and sludge drying.
I
hope this gives a small insight into
the types of environmental work done
by Biosystems Engineers!
