D&B’s experience encompasses engineering complete sewer system projects and extensions and pumping stations.
Our extensive experience in conducting sanitary sewer surveys and alternative rehabilitation analysis and design includes producing contract documents for complete replacement and also for in-line repair/rehabilitation. Our analyses consider the economic impact of both the capital and indirect costs involved relative to the involved residential and commercial areas.
Owner preferences for any specific alternatives are incorporated into the evaluation reports. The reports provide technical, environmental and cost impacts of each of the considered approaches, and also include non-cost impacts such as homeowner and business inconveniences factored into the analyses of the various alternatives.
Experience & Expertise
D&B has designed over 50 pumping stations, both new and rehabilitated, ranging in capacity from 100 gallons to 210,000 gallons per minute. Design aspects typically include:
- Installation of multiplex telemetry systems
- Flow metering
- 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
- Odor control systems
Pumping Station Force Mains & Estuarine Outfall
D&B has designed numerous pumping station force mains up to 2½ miles long. Force main routes are selected to minimize utility disruption, environmental impacts, traffic issues, homeowner inconvenience, and commercial impacts, while also balancing long-term structural stability and cost.
D&B has designed several estuarine outfall projects featuring pipes ranging in size from 36 inches to 120 inches in diameter.
