Dvirka and Bartilucci Consulting Engineers (D&B) has provided engineering and construction management for numerous sanitary sewage collection systems and pumping stations. The firm has handled complete sewer system projects, as well as numerous extensions of sewage collection systems.

D&B has extensive experience in conducting sanitary sewer surveys and alternative rehabilitation analysis and design. The firm has produced contract documents for complete replacement and for in-line repair/rehabilitation. D&B’s analysis takes into account the economics of the project on both a capital cost and as an indirect cost to the residents and commercial areas that may be affected.

Owner preference for specific alternatives is incorporated by the preparation of an alternative evaluation report which provides the technical, environmental and cost impacts of all approaches. In this way, non-cost impacts such as inconvenience to homeowners and businesses can be factored into the alternative selection.

D&B has designed over 50 new and rehabilitated pumping station projects ranging in size from 100 gallons to 210,000 gallons per minute. In addition to new pump installations, the design aspects of these projects include installation of multiplex telemetry systems, flow metering, mechanical, electric, ventilation equipment, structural and architectural repairs, installation of electrical generating and transmission facilities, new electrical substations, pump speed control systems, bypass pumping systems (for construction) and odor control systems.

In addition, the firm has handled the re-routing of sewage flows between treatment plants via force mains from a few hundred feet to over 2½ miles long. Also completed were several estuarine outfall projects with pipe sizes from 36-inches to 120-inches in diameter.

Force main routes are selected to minimize utility disruption, environmental impacts, traffic concerns, homeowner inconvenience, and commercial impacts while balancing long-term structural stability and cost.

D&B is a full-service firm that will complete all required studies; environmental reviews and permit acquisition; preparation of preliminary, conceptual and detailed design documents; remediation of any site contamination; design services during construction; resident engineering and construction management/schedule services; operation and maintenance manual preparation; start-up and training services.
