At Baskerville-Donovan we recognize that our region’s growing population and limited natural resources present environmental engineers with a wide variety of complex technical challenges. Our environmental professional staff is up to the challenge. We provide a wide range of services, including: water supply, wastewater treatment design, pipeline design, pumping design, reclaimed water, construction administration and environmental permitting. For our plant projects, we maintain a full staff of MEPS engineers for mechanical, instrumentation and controls, lighting and structural engineering support. We have the ability to complete projects of almost any size and scope – on time and in budget. Over the years, Baskerville-Donovan has assumed a leadership role in the Southeastern United States in the area of environmental engineering; with our staff permitting the first total reuse system along the Florida Gulf Coast - and the first AWT system discharging to a wetland.
A growing population with limited natural resources is the most pressing environmental issue facing our global community today. Acutely aware of shrinking water supplies, our firm is a leader in the development of new supply alternatives as well as the implementation of conservation measures to preserve the resources we have. Baskerville-Donovan was the first firm to develop total reuse systems for wastewater (eliminating any need for surface water discharge) in Northwest Florida. Our designs have met irrigation and other non-potable needs while preventing the waste of limited groundwater resources. Our engineers designed and obtained permits for the first Advanced Wastewater Treatment system discharging to a wetland in Northwest Florida.
At Baskerville-Donovan, Water and Wastewater Treatment design is in our blood, and we take great pride in our work. Our firm provides a wide range of water and wastewater services, including:
- Wastewater Treatment
- Wastewater Collection System
- Water Treatment
- Water Distribution System
- Pump Station Design and Rehabilitation
- Special Services, Feasibility Studies and Planning
Wastewater Treatment
Baskerville-Donovan has completed numerous recent wastewater treatment projects throughout Florida and Alabama, including design of facilities ranging from advanced treatment plants and MBRs to secondary treatment level plants. The design of wastewater treatment plants is centered around the effluent disposal limits. For many clients these effluent limits are established by public-access reuse at golf courses, application at RIB sites and future alternative locations. The effluent limits are analyzed to the influent characteristics of the waste stream and used to establish the treatment process design requirements. Our engineers have enjoyed recent success in re-rating WWTPs. For example, recently, Baskerville-Donovan engineers re-rated the Dade City WWTP from 1.2 to 1.5 MGD AADF through FDEP. According to the City Engineer, Jose Gil, PE, this re-rate capacity was regarded by the City as a tremendous success. The effort resulted in saving in excess of $2 million in construction dollars for the City’s Wastewater System Fund.
If more stringent effluent limits are required by FDEP, our firm has the in-house capability available to modify the treatment process from an existing activated sludge process (secondary treatment) to a process (possibly advanced wastewater treatment) that will significantly reduce the nitrogen and phosphorus levels to meet the effluent limits required by the new discharge types. In many cases, we will also save the client operating energy by establishing anaerobic and anoxic zones in the WWTP which eliminates the high cost of oxygen added to the facility. In addition to process modifications, the client may request additional expansion of the plant capacity. Treatment plant processes will be evaluated and upgraded where necessary to bring the facility to the client’s desired capacity.
Because we are primarily focused on local government clients, we are particularly sensitive to the unique expectations for locally managed wastewater treatment facilities. Our engineers work closely with each client to establish the most effective means of treatment; ensuring that the client ends up with the treatment processes and equipment they desire for operations.

Wastewater Collection
Our company has designed almost every type of collection system utilized in the southeastern region, including gravity, low pressure, vacuum, and the PEP system. Our team has the full range of experience; we have designed and permitted all types of new and rehabilitation projects commonly encountered throughout the southeast. Baskerville-Donovan has helped communities in Florida and Alabama minimize their Infiltration and Inflow (I&I) problems with SSES work. We are available to apply SSES, I&I rehabilitation, and new collection system design expertise to meet the needs of any client, large or small.
Water Treatment
Baskerville-Donovan has completed numerous water supply and treatment projects throughout Florida and Alabama, including designs for facilities ranging from smaller wellfields to a 48 MGD high-rate ballasted flocculation water treatment plant. Our approach to water treatment plant design is based on the drinking water standard limits and the constituents found in the water supply source. The water sources and constituents are thoroughly evaluated as we work with the client to establish the water supply and treatment process requirements.
Dependent on the preferred water source and selected treatment plant processes, Baskerville-Donovan has all of the in-house capabilities to expand or modify the client’s water treatment plants. In addition to process modifications, the client may request additional help from our engineers to assist with operational optimization and extend plant capacity. Treatment plant processes will be evaluated and upgraded as required.

Our team has the personnel to provide the solution for any water distribution system including all main line equipment and related appurtenances. Our engineers have broad experience in Florida and Alabama, and are qualified to design and permit all new and rehabilitation project types associated with distribution systems. Over the years, we have helped hundreds of communities solve flow, pressure, chlorine residual, contaminant removal, biofouling, and leak problems.
Pump Station Design and Rehabilitation
Our firm has successfully completed hundreds of water and wastewater pump station design and rehabilitation projects throughout Florida and Alabama. These projects have ranged from the rehabilitation of small 100 gpm wastewater lift stations to new 60 MGD water supply pump station projects.
These improvements include rehabilitation or replacement of wastewater lift stations that are in need of repair because of their current condition. Our engineers have managed and executed all aspects of SSES work to meet I&I reductions for our clients. We have managed and executed the rehabilitation of entire local government collection systems. This experience includes rehabilitation of the pump stations including entire wet wells, pumps and piping, and electrical controls and instrumentation.
Typically, Baskerville-Donovan uses standard pump station designs for almost all lift station design scenarios. We have developed our own in-house digital models, an approach that allows our staff to quickly and cost effectively design pump stations with the client’s staff. All design activity takes into consideration client needs. We are sensitive to client priorities and understand the need to minimize front-end construction costs and long-term operating costs. Our engineers will work closely with the client to identify the most effective equipment and materials; this practice ensures that client staff is completely satisfied with equipment selections for operations. The nearest regional Baskerville-Donovan Regional Office will manage, design, and permit the pump station projects to ensure that project meetings are convenient for the client.
