Wastewater Treatment

Turkey Creek WWTP-Panoramic

From our inception, wastewater facility planning has been a primary emphasis of Allgeier, Martin and Associates, Inc. We have a strong background in the planning and design of wastewater treatment facilities for municipalities, industries, commercial establishments. We stay up to date with the regulations and regulatory trends, monitor technological advances in the industry, and strive to provide our clients with reliable wastewater treatment facilities that will consistently meet regulatory requirements, while also providing economy of construction and operation. Each project reflects an in-depth study of the individual client's situation and a recommended treatment option that meets not only the regulatory criteria established for the project, but also the client's specific needs. Each facility is designed to be "operator friendly" both in terms of operability and operating costs.

We have successfully completed projects of all sizes, with various levels of complexity, from simple lagoons and recirculating sand filter secondary treatment designs, to larger, advanced treatment designs, employing combinations of fixed growth and various activated sludge processes, anaerobic and aerobic sludge digestion, cogeneration, chemical treatment, filtration, and disinfection. We have designed non-discharging, land application systems for flows up to 2.8 mgd and routinely address current or anticipated future nutrient removal requirements. Our extensive list of satisfied clients and award-winning wastewater treatment facilities attest to Allgeier Martin's ability to provide first-rate planning, design, and construction oversight as we assist clients in meeting their wastewater treatment needs.

Project Experience

  • Joplin, MO

    Turkey Creek Wastewater Treatment Plant

    Turkey Creek WWTP - Joplin, MO

    Joplin’s Turkey Creek Wastewater Treatment Plant is a combined fixed growth and activated sludge type treatment facility designed for an average flow of 15 million gallons per day. Allgeier Martin has provided planning, design, and construction oversight of three major projects and several other projects of lesser scope that now provide a facility with advanced wastewater treatment capabilities. The facility has received awards for its energy-conserving design and its innovative treatment and disposal of waste biosolids.

    Wastewater treatment includes raw sewage screening and pumping, primary clarification, trickling filter towers, intermediate clarification, oxidation ditch aeration basins, final clarification, tertiary filtration, ultraviolet disinfection, and reaeration prior to discharge. Peak flow pumping facilities allow for the delivery of up to 90 million gallons per day to the treatment facilities and an adjacent flow equalization basin.

    Waste primary clarifier solids are anaerobically digested, and the methane gas generated by this process is used to heat sludge and buildings, and to generate on-site electrical power. Waste activated sludge is aerobically digested. Facilities allow for dewatering the stabilized biosolids prior to land application, or the City can land apply liquid waste biosolids.

    Shoal Creek Wastewater Treatment Plant

    Shoal Creek WWTP - Joplin, MO

    Allgeier Martin provided planning, design, and construction-phase services for the original Joplin Shoal Creek WWTP, and is now involved in a major expansion to this facility. The facility is currently being upgraded to provide advanced treatment of an average design flow of 7.2 million gallons per day, and peak flows to 19 million gallons per day.

    When completed, wastewater treatment facilities will include screening, primary clarifiers, trickling filter towers, oxidation ditch aeration basins, final clarifiers, tertiary filtration, ultraviolet disinfection and reaeration prior to discharge. Peak wet weather flows in excess of plant capacity are automatically diverted to flow equalization basins and are returned to the plant for treatment when flows subside.

    Waste primary clarifier solids are anaerobically digested, and the methane gas generated by this process is used to fuel boilers and an electric generator for heating of sludge and buildings and on-site power generation. Waste activated sludge is aerobically digested. Facilities allow for the thickening of the stabilized biosolids to reduce sludge hauling costs associated with land application of the liquid waste biosolids.

  • Webb City/Carterville, MO

    Center Creek Wastewater Treatment Plant

    Center Creek WWTP - Webb City, MO

    Allgeier Martin provided planning, design and construction phase engineering services for wastewater treatment facilities located in Webb City, MO., but also serving the towns of Carterville and Oronogo. The regionalization of the treatment facilities required the construction of several miles of interceptor sewers to deliver wastewater to the centralized location.

    The plant has been expanded to provide a 4.8 million gallons per day average and 9.3 million gallons per day peak flow capacity. Plant components include raw sewage pumps, two parallel oxidation ditch type activated sludge basins, four final feed clarifiers, submersible sludge pumps, ultraviolet disinfection facilities, flow equalization basins, sludge holding lagoon, and laboratory and control building.

  • Monett, MO

    Eisenhower Wastewater Treatment Plant

    Eisenhower WWTP - Monett, MO

    Allgeier Martin provided planning, design, and construction phase engineering services for major wastewater treatment plant expansions for the City of Monett, Missouri. Improvements were necessitated by a change to advanced effluent limits, problems with the plant’s rotating biological contractor process facilities, highly variable industrial waste discharges to the system, continuing increases in the biological and hydraulic loading of the system, and the City’s desire to improve nutrient removal capabilities of the system.

    The improvements resulted in a facility designed to handle an average flow of 6 MGD and a peak flow of 12 MGD, with excess flows diverted to a flow equalization basin. Facilities include raw sewage screw pumps, mechanical screening, and aerated grit removal, prior to biological treatment facilities. The unique biological treatment facilities utilize trickling filter towers and activated sludge basins to treat to “tertiary” levels, while also providing biological nutrient removal. Final clarification, effluent filtration, and ultraviolet disinfection follow the biological treatment facilities.

    Allgeier Martin is currently working with the City to replace existing sand filters that have exceeded their design life are in need of additional capacity.

  • Carthage, MO

    Carthage Wastewater Treatment Plant

    Carthage, MO WWTP

    Allgeier Martin provided planning, design construction-phase services for a major expansion of the Carthage WWTP. The project increased the capacity of the plant from 4.5 MGD to 7.0 MGD, providing secondary treatment for domestic, commercial, and significant industrial wastewaters. The plant expansion included the addition of raw sewage pumping capacity and construction of new grit removal and screening facilities. Intermediate pumping was provided in conjunction with three new final clarifiers. Existing clarifiers were converted to activated sludge basins via the inclusion of turbine type aerators. Chlorination/dechlorination facilities were replaced with ultraviolet disinfection equipment. Sludge handling facilities were expanded significantly by the addition of a gravity thickener, aerobic digester, and sludge holding tanks.

    Most recently Allgeier Martin has been retained for planning and design of improvements to the plant in anticipation of restrictive ammonia limits, and to improve sludge handling facilities. The proposed improvements include adding fine bubble diffusion in the activated sludge facilities to achieve nitrification/denitrification, and improvements to aerobic digestion facilities.

  • Nevada, MO

    Nevada Wastewater Treatment Plant Improvements

    Nevada, MO WWTP

    Allgeier Martin provided design and construction phase services for the City’s recently completed WWTP expansion. The project increased the plant’s hydraulic capacity from 4 to 10 million gallons per day through the addition of two new aeration basins and two new clarifiers, along with expansion of the facility’s raw sewage pumping capabilities. Grit removal and screening facilities preceded the biological treatment and clarification steps, and ultraviolet disinfection was provided prior to discharge.

    The original activated sludge aeration basin was converted to aerobic digesters and sludge holding tanks and the existing clarifiers remained as part of the treatment process. Two new aerobic digester basins were added to the treatment facility by the conversion of the existing aeration basins. A lime mixing structure, a lime silo and feed equipment were added to the facility to make the sludge more suitable for land application.

    A new, larger lab building was also included in the project to provide a lab area, restroom and locker facilities, offices, meeting and break rooms, and a SCADA based motor control center. Throughout the facility variable frequency drive pumps were used to reduce power costs.

  • Carl Junction, MO

    Carl Junction Wastewater Treatment Plant

    Carl Junction, MO WWTP

    Allgeier Martin has been involved in all phases of the City of Carl Junction’s wastewater treatment facilities development. The original 0.42 million gallons per day Wastewater Treatment Plant was designed and constructed in a manner that allowed for expansions that would be able to keep pace with local growth and future changes in regulatory requirements.

    Since completion of the original facility, Carl Junction has experienced growth through residential development unparalleled in their history. In addition, the City has agreed to provide wastewater treatment for the Village of Airport Drive. To accommodate the increased hydraulic load, the City has undertaken three major expansions of the plant. Allgeier Martin was retained to provide planning, design, and construction related engineering services for each project. Upon completion of the ongoing project the plant will have an average capacity of 1.6 million gallons per day and a peak capacity of 5.7 million gallons per day. The first two expansion projects consisted of parallel oxidation ditches with brush rotor aerators, three clarifiers, ultraviolet disinfection, compartmentalized sludge lagoons, and peak flow pumping. The latest expansion consists of adding another oxidation ditch, additional clarification basins, modification of the return activated sludge handling to increase influent pumping capacity, conversion of clarifiers to aerobic digesters, replacement of U.V. disinfection equipment and improvements to the screening facilities.

  • Seneca, MO

    Seneca Wastewater Treatment Plant Improvements

    Seneca, MO WWTP

    Allgeier Martin’s involvement in planning for improvements to the City of Seneca’s wastewater treatment facilities began when the City’s lagoon system began to exceed capacity, effluent limits were tightened, and growth from both domestic and industrial wastewater appeared imminent. An engineering report prepared by Allgeier Martin, concluded a mechanical treatment facility would best fit the City’s needs. Design of the new treatment facilities included two extended aeration treatment basins with nested clarifiers, designed for the treatment of an average daily flow of 0.9 million gallons per day and peak flow of 3 million gallons per day. The plant also includes raw pumping grit removal, mechanical screening, ultraviolet disinfection, aerobic digesters, and a laboratory facility with office space, a motor control center, and SCADA interface.

    The project was somewhat unique in that funding and regulatory permitting were for a Missouri community, with the wastewater treatment facility located in the State of Oklahoma.

  • Coffeyville, Kansas

    Coffeyville Wastewater Treatment Plant

    Coffeyville, KS WWTP

    The City of Coffeyville, Kansas retained Allgeier Martin to complete the design of a new sequencing batch reactor (SBR) type activated sludge wastewater treatment plant, the first of its kind in the State of Kansas. This facility replaced the existing rock trickling filter plant, providing an average capacity of 4 MGD and a peak capacity of 6 MGD through the plant. Peak flow facilities are capable of carrying total flows to 12 MGD. The SBR process was chosen by the City due to its flexibility in nutrient removal. Design elements included raw sewage pumps, grit and grease removal facilities, SBR basins with diffused aeration and mechanical mixers, ultraviolet disinfection and reaeration prior to discharge. Waste sludge is aerobically digested, mechanically thickened, and stored prior to liquid sludge hauling and land application.

  • Odessa, MO

    Odessa Wastewater Treatment Plant

    Odessa, MO WWTP

    Due to the outgrowing of their wastewater lagoon system, the City of Odessa, MO retained Allgeier, Martin and Associates, Inc. to address conditions inherent with the wastewater collection and treatment facilities. A Facilities Plan was developed which addressed the anticipated growth and expansion of the community, the physical condition of the sewers, the capacity of each of the lagoons systems, and the probable forthcoming discharge limits of each of the three lagoons.

    The Facilities Plan recommended a mechanical plant to replace the largest lagoon system as the most urgently needed improvement to treatment. The mechanical plant consisted of dual oxidation ditches, four clarifiers, sand filters, and ultraviolet disinfection. Sludge management at the plant consisted of two aerobic digestion vessels and a sludge drying bed and covered storage system. The nominal hydraulic capacity of the mechanical plant was set at 1.0 million gallon per day with treatment capacity of 10,000 population equivalent.
