City of Gardner, MA —- Headworks Upgrade. Responsible for evaluation of screening and grit removal technology.
Oversaw design of the new facility, including process and building services designs. Primary author of the Preliminary
Design Report.
City of Leominster, MA - WPCF Headworks Upgrade. Oversaw design of the new building which includes a mechanical
fine screen and screenings washpress, and replacement comminutors and slide gates. The new facility was built over the
existing channels while maintaining WPCF flows of up to 30 MGD. Performed hydraulic analysis of flow patterns at full
range of flows for this facility (1-30 MGD). This project also includes the replacement of three influent screw pumps with
new higher capacity pumps to allow pumping redundancy, and construction of a new electrical room and motor control
center. Responsible for contractor oversight during construction.
Town of Hudson, MA - WWTF Upgrade. Evaluated existing plant pumping and headworks systems. Designed upgrade
to the plant headworks, including screening, septage handling, and aerated grit chamber. Evaluated and designed
refurbishments to existing sludge and scum pumps. Designed 1,400 LF force main replacement. Served as lead project
engineer during construction administration of the $14.2M project which included construction of a dissolved air flotation
process for tertiary phosphorous removal. Reviewed shop drawings, payment requisitions, and change orders.
Responsible for contractor oversight during construction, and start-up of the new facility, including performance testing of
the new tertiary equipment.
City of Leominster, MA — Nutrient Removal Upgrades. Design of a tertiary phosphorous removal process at the
Leominster WPCF. Responsible for layout, sizing, and hydraulic analysis of a new ballasted flocculation process for tertiary
phosphorous removal. Evaluated existing chemical storage and pumping systems and designed upgrades. Evaluated
existing buildings and processes for building code compliance. Responsible for contractor oversight during construction
and start-up of the new facility.
City of Leominster, MA - WPCF Aeration Tanks Upgrade. Evaluated the benefits of replacing existing mechanical
surface aerators with new fine bubble diffusers and high-efficiency blowers. Preliminary design tasks included Biowin
modeling of enhanced nutrient removal treatment schemes (continued chemical precipitation vs. aerobic/oxic process vs.
Modified University of Cape Town process) and evaluation of life-cycle costs and benefits of each scheme.
City of Fitchburg, MA - Headworks Upgrade. Design of a headworks upgrade at Fitchburg's Easterly Wastewater
Treatment Facility. Evaluated operational capabilities and lifecycle cost analysis for competing odor control technologies.
Prepared preliminary design report, including basis of design for replacement screening/washpresses and conveyors.
Prepared project evaluation form and State Revolving Loan Fund applications. Evaluated facility's susceptibility to flooding
due to high river levels.
Private Development, Westford, MA - WWTF. Responsible for technical design and project management during the
design and construction of a packaged wastewater treatment facility serving a new commercial development. Prepared
design drawings and specifications for construction of the membrane bioreactor treatment facility. Oversaw construction
and start-up of the new facility. Managed design and construction to allow project to proceed from preliminary design to
start-up in less than 1 year.
Private Development, Mashpee, MA — WWTF. Project Manager for permitting, design and construction of a packaged
wastewater treatment facility serving a housing development. Performed hydrogeological evaluation of the existing site.
Prepared the Hydrogeological Evaluation Report for DEP review and approval. Evaluated treatment technologies for the
new Wastewater Treatment Facility. Responsible for preparation of design documents for the new facility.
Private Development, Hardwick, MA - Hydrogeological Evaluation for a WWTF. Evaluated the suitability of several
sites on the development’s land for wastewater effluent disposal. Designed a protocol for a hydraulic loading test of the
proposed disposal area. Coordinated with DEP during the permitting phase and hydraulic loading test.
