Water Resources & Wastewater Projects

New Water Treatment Plant

  • Midwest provided construction administration for a new 6.0 MGD water treatment plant (WTP) serving over 12,000 people across 20 entities near Fredonia, Kansas. The new facility replaced an aging, flood-prone plant that faced operational challenges, including outdated equipment, high turbidity levels, and insufficient storage and distribution capacity.

    Under an agreement with PWWSD No. 23, Danny oversaw the construction, offering daily observation, materials testing, documentation, and project management support. The upgraded WTP, with over 1,000 horsepower of pumps, three miles of large-diameter waterlines, and over a million gallons of storage, now meets current and future demands, including potential system expansions.

Western Expansion Merger Project

  • 25 Mile Merger Between Three Entities

    In 2018, PWWSD No. 23 enlisted Danny Coltrane to amend a prior USDA project report to extend water supply service to the City of Howard and Elk County RWD No. 2, successfully securing USDA funding. Midwest Engineering Group was contracted to provide full consulting services—including design, permitting, easement acquisition, and construction administration—for a 28-mile supply waterline featuring a triplex booster pump station and a 400,000-gallon elevated storage tank. The project included various pipe sizes, master meter and valve control vaults, fire hydrants, flushing assemblies, SCADA systems, and multiple utility crossings. Once completed, it enabled PWWSD No. 23 to serve as the primary water supplier for the new service areas, despite challenges such as material delays and subsurface rock.

Comprehensive Water System Improvements

  • Midwest Engineering provided comprehensive consulting services to develop a Professional Engineering Report (PER) for a new 1 MGD water treatment plant, water storage, booster pumps, and distribution system, aligning with state and federal funding requirements. The PER included budgeting, financial analysis, and present worth comparisons to help the city secure favorable 40-year financing at 2.125% interest and grant funding. Using GIS data, city records, KDHE design standards, and other documentation, Midwest evaluated the existing systems and designed improvements including well rehabilitation, clarifiers, filters, chemical feed systems, SCADA controls, and a backup generator. The project also includes replacing all non-PVC water lines to comply with new EPA lead and copper rules. Midwest is providing full design, bidding, and construction phase services, including on-site construction observation, and helped the city secure over $16.6 million in funding through USDA Rural Development.

Water Treatment Plant (WTP):
Comprehensive Plan & Professional Engineering Report

  • The City of Chanute, which has operated its own water utility since 1894, engaged Midwest Engineering to develop a Preliminary Engineering Report (PER) to evaluate rehabilitation options for its aging water treatment plant (WTP). The PER included financial and rate reviews, population projections, and system assessments—providing the basis for securing private funding. As part of ongoing improvements, the City entered a CMAR agreement with Crossland in November 2024 to begin construction focusing on the clarifier and chemical feed systems, while deferring upgrades to the Clearwell, High Service Pump, and Disinfection systems due to financial constraints.

    In parallel, Chanute is addressing severe inflow and infiltration (I&I) issues in its wastewater collection system, with rates 10 to 20 times above KDHE limits. Anticipating stricter regulations, Midwest is assisting the City in creating a 5–7-year strategic plan to collect system data, identify deficiencies, and prioritize repairs. Immediate efforts include spot repairs and phased infrastructure upgrades—such as lift station rehabilitation and line replacement. Longer-term improvements will focus on private-side I&I mitigation and upgrades to the wastewater treatment plant’s core systems, all aligned with updated KDHE permit requirements and flow data.

Water Treatment Plant Improvements

  • Midwest Engineering Group provided consulting services to Rural Water District No. 2 in Miami County, Kansas, to evaluate and plan comprehensive upgrades to its water treatment plant (WTP). What began as a project to replace the aging above-ground Clearwell expanded into a $38 million, multi-phase improvement plan addressing discharge flow rates, treatment processes, and storage needs. Phase I ($5M) is complete, and construction on Phase II ($16M) is underway, with completion expected in 2025. These upgrades will expand the WTP’s capacity from its current 6.0 MGD—originally built in 1984 and expanded in 1998—to 12 MGD to meet increasing demand. The existing treatment process includes high-rate clarification, a contact basin, and filtration, and Phase III planning is under consideration.

    RWD No. 2 supplies treated water across 300 square miles in northern Miami County and neighboring areas, serving multiple cities and rural water districts. The distribution system is made up of 2-inch to 30-inch ductile iron and PVC piping, with six high service pumps at the treatment plant providing a firm pumping capacity of 6 MGD.

Multiple Waterline Improvement Projects (RWD8)

  • Midwest Engineering provided consulting services to Allen RWD8 for two waterline improvement projects aimed at addressing low water pressure. The first project involved upgrading approximately 5 miles of 3” waterline to 6” CL200 PVC main and 0.5 miles to 2” CL200 PVC. Midwest handled design plans, permitting with KDHE, and construction phase services including contract management, inspections, pay estimates, and as-built documentation.

    The second project upgraded 3.5 miles of 2.5” waterline to 6” PVC and included installation of tracer wire, gate valves, fire hydrants, clean-outs, and various utility crossings. Midwest performed similar duties as in the first project and provided construction observation services for the County throughout the process.

Multiple Waterline Improvement Projects (RWD4)


  • Neosho RWD #4 maintains a 354-mile water distribution network serving 1,247 meters across Neosho, Labette, and Wilson counties. Midwest Engineering Group has provided ongoing consulting services based on a long-standing master plan to address system issues such as pressure loss and water leakage. Recent projects include the Trego and Elk Road Improvements, which involved 5.5 miles of new 4” HDPE waterline funded through ARPA, and the Ottawa and Elk Road Waterline Upgrades, replacing aging 2” lines with over 4.7 miles of 4” PVC to improve capacity and service reliability. Additional projects include the Pratt Road upgrade to address low pressure, the installation of a 1.4-mile supply line extension along Elk Road, and a system-wide hydraulic model update and master plan to optimize performance and reduce water loss.

    Currently, Midwest is working on a major 107-mile Loop and Branch Line Improvements Project to replace aging 1965 infrastructure. The project includes installing a mix of 2” to 8” waterlines, a triplex booster pump station, a 400,000-gallon elevated tank, and numerous crossings and appurtenances. Engineering services provided include design, permitting, environmental mitigation, easement acquisition, and construction oversight. These coordinated upgrades are designed to increase water pressure, expand capacity, and position the district for sustainable future growth.

Transportation Projects

Road Bridge Replacement

  • Oakland Road Bridge No. 15400 Replacement

    This project involved providing design, bidding and construction administration/observation services for replacing a damaged bridge with a new single-span precast box beam bridge. Located on Oakland Road, the replacement structure spans 34 feet and features eight adjacent precast concrete box beams (15" x 34"). The bridge is supported by reinforced concrete abutments on spread footings, ensuring stability and durability. The bridge replacement removed bottleneck effect to flow saving erosion and road washouts while improving flow, safety and accessibility for vehicles along this aggregate roadway.

Streambank Stabilization

  • Moniteau Creek Streambank Stabilization

    This project involved the design, bidding, and construction oversight for streambank stabilization along Moniteau Creek near Clarksburg Drive to protect an adjacent roadway. The work included realigning the stream and implementing structural and vegetative erosion control measures, such as 10 bend-way weirs and Longitudinal Peak Stone Toe Protection (LPSTP), to redirect flow and reduce bank erosion. Native vegetation was also planted to provide long-term stability and ecological benefits. The project delivered a sustainable solution that safeguarded infrastructure while preserving the natural function of the creek.

Retaining Wall Bank Stabilization

  • Cooper County

    This project included design, bidding and construction administration for the installation of a block retaining wall along the north roadway embankment within the County right-of-way. The retaining wall was necessary to stabilize the embankment and reduce bank sloughing adjacent to a nearby residence. Due to limited excavation options, the wall incorporated soil anchorage to enhance stability.

    The final structure consists of precast modular retaining wall blocks, with heights varying from 5'4" to 10'-8", spanning 116 linear feet. A 4-foot chain-link fence was installed along the top of the wall to improve safety. The resident’s drainage system was redirected to discharge away from the wall. This project effectively stabilized the embankment, protecting both the roadway and nearby property while ensuring long-term safety and resilience for the community.

Aluminum Box Culvert

  • Midwest Engineering Group worked with Cooper County after a FEMA declared disaster damaged an existing 7' x 12' CMP. The existing CMP’s invert separated, causing debris to collect and block flow. Midwest served as the Engineer of Record for the project and replaced the structure with a 16'-2" wide, 5'-1" tall, 56'-0" long bottomless Aluminum Box Culvert (ALBC) supported on concrete spread-footings with aluminum headwalls and wing walls. The bottomless aspect of the new ALBC eliminated the debris collection issue and allowed for a natural stream bed. To accommodate the stream’s abrupt turn of flow at discharge, the ALBC was rotated and skewed wing walls were used to parallel roadway for ditch flows. The ALBC assembles quickly to reduce road closure delays which was convenient for local farmers and residents. Midwest provided hydraulic analysis, structure sizing, site design, prepared bid/construction documents and construction administration/observation for the County.

Road Bridge Replacement

  • Sycamore Creek Road Bridge No. 6000005 Replacement

    Boone County received a call regarding a deteriorated bridge to a subdivision, but neither the State nor County had any record of it. After reviewing the structure, it was closed to traffic and the adjacent lo water crossing was the subdivision’s only access. With replacement being a high priority, Boone County and Midwest Engineering Group, LLc worked together to quickly design, bid and construct a new bridge structure. Midwest was able to utilize Boone County’s survey data to coordinate, design permit, and prepare final construction documents in approximately 3 months. The new 36' long bridge passes the 25-year flood event and consists of precast concrete box girders, protective topping slab, geosynthetic reinforced soil approaches and concrete vertical abutments. The County was able to complete construction and open to traffic within the year.

Sinkhole Remediation & Culvert Installation

  • A sinkhole along Rodeo Drive caused the roadway to be flooded in large rainfalls and its erosion encroached the roadway. Midwest worked with a geotechnical engineer ad contractor to fill a void under the roadway with 18 cubic yards of flow-able grout to stabilize the roadway. Once stabilized, the area was drained and a culvert installed under Rodeo Drive and an adjacent west field consisting of approximately 402 liner feet of 36" diameter dual-wall HDPE pipe, 32 linear feet of 30" diameter dual-wall HDPE pipe, two riser inlets (12" & 30") and attachments along with filling the adjacent sinkhole. Shortly after the project completion, the area received a large rainfall, which was handled as designed and allowed traffic to pass safely.
