Our past projects have encompassed a variety of entities from large, complex municipal systems and facilities to systems serving, small rural communities or developments. Typical services provided by our firm are wide ranging and consist of system-wide planning and design, inflow/infiltration abatement studies, permitting, GIS system development and maintenance, highway and railway bores, stream and waterway crossings, pump stations, pressure sewer lines, large diameter interceptor sewersand system expansions of various sizes. Allgeier Martin has also established itself as a leader in the sanitary sewer collection system rehabilitation field by using innovative techniques to plan, design and manage projects utilizing trenchless techniques for main line, lateral line and manhole renovations in an efficient and organized manner. From planning through design, permitting and construction, our engineers and staff are acquainted with the procedures that will result in the timely completion of proposed projects. Design criteria focuses upon implementing an efficient and cost-effective collection system for the community it serves, by minimizing system maintenance requirements and costs associated with its continued operation.
Disaster Recovery Sanitary Sewer Improvements | Joplin, MO
The City of Joplin selected Allgeier Martin to plan, design and administer a project to renovate and replace a majority of the sanitary sewer collection system within the area affected by the May, 2011 tornado. This project includes sanitary sewer main replacement/rehabilitation improvements including some capacity upgrades to larger interceptor sewer lines equating. Approximately 327,950 lineal feet of 8” to 18” sanitary sewer main and associated support structures will be addressed by this project. The total project area covered by the project is approximately 2,742 acres.
Included within the project will be the Closed Circuit Television Inspection (CCTV) of each of the sanitary sewer lines located within the project area. From the CCTV data, each line and associated manhole will be evaluated and prioritized as to their operating condition and need for rehabilitation. Service lateral location and condition of their connection to the main sewer line will also be evaluated as part of this process. From the gathered data, rehabilitation projects will be identified that include improvements to the lines and manholes identified as being in the worst condition as well as replacement of service lateral connections, installation of lateral cleanouts and lateral line renovations. Each of the eight (8) interceptor sewers that exist within the project area will be evaluated as to their condition, capacity and ability to meet future flow requirements and subsequently replaced or improved as necessary. Updates to the City of Joplin’s GIS system with the accumulated data and locations of the planned/completed improvements for the sanitary sewer lines and manholes throughout the project area will be ongoing for the duration of the project.
Strict deadlines for completion of the work have been set forth in order to retain and utilize available funding obtained through the Community Development Block Grant Disaster Recovery (CDBG DR) program. Allgeier Martin is responsible for the planning and administration of these sanitary sewer improvements including preparing budgets and the scheduling of design, bidding and construction of this work, in order to meet the established funding deadlines. The project planning began in August of 2014 with the bidding of the first portion of the improvement work set for March of 2015. Various aspects of the project are anticipated to extend through the year 2018. The estimated costs of the sanitary sewer improvements as part of this project are currently set at just over $21 million.
Lone Elm Drainage Basin Inspection/Evaluation GIS Integration | Joplin, MO
The project consisted of the closed circuit television (CCTV) inspection and evaluation of approximately 106,000 lineal feet of 8-inch through 18-inch diameter gravity sewer lines, the visual inspection and evaluation of approximately 415 manholes, and the smoke testing of approximately 50,000 lineal feet of 8-inch diameter gravity sewer line within the Lone Elm Drainage Basin in order to establish a working plan for the repair, replacement, and/or rehabilitation of this portion of the City’s wastewater collection system. Additionally, in order for the City to better utilize the inspection and evaluation data, the information was merged with their current GIS wastewater collection system map.
Initially, the City provided their base GIS wastewater collection system map identifying each component (pipes and manholes) by a unique identification number and existing wastewater collection system information that the City had already recorded (pipe material, pipe, length, manhole material, etc.). The CCTV inspection, manhole inspection, and smoke testing were then conducted utilizing the already established unique identification numbers for reference. Once the inspection data and the smoke testing defects were fully compiled, the components were evaluated and assigned a numeric rating based on the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment and Certification Program (PACP). Additionally, a general cost estimate for the rehabilitation of the individual components was established. Lastly, all the inspection and evaluation data was merged with the City’s existing GIS wastewater collection system map.
The newly created GIS wastewater collection system map includes all the information that the City will need in order to plan and budget for current and future wastewater collection system repair, replacement, and rehabilitation projects within this drainage basin. Additionally, as the City completes these construction projects the GIS data can be updated to better track, categorize, and inventory the Lone Elm Drainage Basin’s wastewater collection system.
Crossroads Parallel Sewer | Joplin, MO
The Crossroads Parallel Sewer Project consisted of two phases of construction to increase the capacity of the existing interceptor sewer serving a large portion of the City of Joplin. The area served included approximately 14,100 acres, a portion of which was already developed and a portion that was anticipated to develop within the foreseeable future. The interceptor line was sized to accommodate the existing development and future development within the design life of the pipe. A section of the existing line that was still in relatively good condition remained in service and a parallel line was installed. This helped to keep the size of the pipe and construction costs down. The remainder of the existing line encompassed by this project was replaced. Although replacement was obviously more costly, it also represented a means to reduce inflow and infiltration into the City’s system. Allgeier, Martin was retained to provide preliminary, design, and construction phase engineering for both phases of the project. Each portion of the project was completed within the time frame constraints set forth in the grant funding for the project, and within the limits of the available funding. Challenges on the project included finding a means to economically crossing Range Line Road and Newman Road. This was accomplished by making use of the existing Turkey bridges for these roads and utilizing open cut trenching techniques to install the pipe under the bridges in lieu of boring these roads. The size of the pipe and angle of entry for existing and proposed lines coming back into a common manhole was also difficult; standard round manholes were not large enough to accommodate this project. As a result, a number of “junction manholes” were designed to accommodate the angles and pipe sizes associated with this project.
