Wastewater Engineering

Background

Sewer System Analysis and wastewater treatment facilities design has been the pillar of GEA's practice since the firm was founded by Steven M. Gamelsky. Mr. Gamelsky is a dedicated environmental engineer who was involved in significant wastewater projects over a decade ago. Since establishing GEA, work in this area has contributed to the firm's success and reputation for outstanding performance.

Licensed, experienced professional resources are available to achieve client objectives, whether the need is immediate and specific or complex and long-term. All phases of wastewater facilities management can be addressed from initial planning and feasibility studies, to wastewater monitoring, sampling and assessment, to design and construction management.

Professional staff include civil, environmental, mechanical, structural and electrical engineers, architects, draftsmen and construction inspectors. As a multidisciplinary firm, GEA has available environmental scientists, hydraulic engineers, hydrogeologists, affiliated analytical laboratories, and computer support services to provide technical support for resolution of related project issues.

GEA is involved in all phases of sewer system and wastewater management, including consulting , planning, preliminary and final design, preparation of plans, specifications and bid documents, bid evaluation, contract administration, construction supervision / inspection, plant startup and operator training.

Planning

GEA provides comprehensive sewer system and wastewater treatment planning studies, feasibility studies, master plans and wastewater facilities plans designed to meet the requirements of facilities, assess sewer system infrastructure and rehabilitation, and prepare maps, plans, tabulations, reports, and presentations. Additionally, the firm has the resources to perform infiltration / inflow studies, sewer flow monitoring and wastewater sampling programs.

Sewer System Studies

GEA performs sewer system evaluation surveys and infiltration / inflow investigations to determine the condition of underground piping systems in order to design for system rehabilitation. The firm has the special qualifications needed to efficiently investigate facility requirements for expansion, rehabilitation, and/or modification to sewage collection systems, as well as investigate alternative sewage collection, treatment and disposal options. The acquisition of accurate field information including wastewater flow and quality data, sewer inspections, smoke test results, TV inspection, and computer hydraulic analysis provide a solid foundation for the assessment of rehabilitation alternatives.

Wastewater Facilities Design

GEA's design capabilities for wastewater treatment facilities and sewerage systems includes plant modifications, expansion, and upgrades as well as design of new facilities and closure of old facilities. The firm is experienced in the design of treatment plants ranging in size up to 75 million gallons per day (MGD), pump stations u to 30 MGD, and transmission systems, including interceptors, force mains and outfalls, as well as lateral sewers and collection systems. GEA has extensive experience designing activated sludge, trickling filter, rotating biodisc and natural wetland treatment systems.

Sludge Management

The firm has experience evaluating sludge management alternatives including land application of liquid, dewatered, or composted sludge and thermal reduction via multihearth or fluidized bed incineration with heat recovery.

Pretreatment Studies

GEA provides the necessary practical experience to implement effective pretreatment programs under USEPA guidelines. Assessment of the effects of priority pollutants on publicly owned treatment works include VOC and heavy metals source determination studies. Impacts upon sludge quality are evaluated.
