The Client has asked Xxxxxx-Xxxx to assist them in determining the cause of the Permit Set drawings dated May 2023pumping issues and providing recommend alternatives to correct these issues. Xxxxxx-Xxxx will provide the services specifically set forth below. Xxxxxx-Xxxx will review available documents including survey, land plats, utility drawings, etc. for the lift station and force main and will develop a preliminary plan.

Xxxxxx-Xxxx will evaluate the FM records and quantity in-situ profile to determine up to four (4) locations for investigating the FM. Parameters for these locations include minimized liquid volume in the FM requiring disposal as well as areas of peak interest such as low points along the FM profile and ARV locations. The intent of these identified locations will be to perform CCTV, if possible, and understand the general condition of the “onFM along its length and profile. As a part of this analysis, Xxxxxx-call” services provided Xxxx will perform onsite visual investigation.
