MAWSS CMOM Program Development
Inspection and Evaluation of Lift Stations

MEI served as a subconsultant on the project.  Project tasks included evaluation of lift station performance, the development of a critical spare parts list for the lift stations, lift station standard specification review, and development of pump standardization program.

Odor and Corrosion Evaluation

MEI served as a subconsultant on the project.  Project tasks included collecting product information for various odor and corrosion control options, contacting vendors to perform pilot studies at selected lift stations, accompany vendors on site visits to stations, collecting and evaluating pertinent data for determination of product performance, and developing cost estimates for implementation of odor and corrosion control equipment.

MAWSS Halls Mill and Eslava Creek Force Main Evaluation

MEI served as a subconsultant on the project.  Project tasks included reviewing existing force main “Record Drawings” and development of an overall profile to make a preliminary determination of areas of potential risk and perform visual inspections of force main where it was above ground to assess outer wall and air release valve conditions.

MAWSS GIS Conversion and Field Data Collection

MEI served as a subconsultant on the project.  The project included obtaining sub-meter locations for all interceptor and non-interceptor manholes, as directed prime, contained in the sanitary sewer collection system.  In addition, rim elevations, invert elevations, invert pipe sizes, discharge force main sizes, manhole diameter, manhole depth, and other miscellaneous features were collected.
