Edward Ball Wakulla Springs State Park, Sanitary Sewer Investigation

Dear Mr. Sandel:

Hydra Engineering & Construction, LLC is pleased to provide the attached proposal summary and man-hour documentation for the Sewer Force Main Investigation at Edward Ball Wakulla Springs State Park.

Please see the attached proposal summary and deliverables.

Sincerely, Leslie Weiss, P.E., C.G.C.

Sewer –Edward Ball Wakulla Springs State Park

As requested, Hydra is submitting this proposal to provide the sewer main investigative services at the Wakulla Springs State Park. Hydra will conduct a comprehensive investigation into the failure of the existing sanitary sewer force main and the premature deterioration of the associated lift station pumps and infrastructure. The objective of this study is to determine the root cause(s) of the observed issues, including suspected excessive pressure events within the force main and the potential presence of aging infrastructure that may have surpassed its intended service life.

To achieve this, Hydra will undertake a series of investigative steps aimed at evaluating the condition of the force main system, confirming the performance of critical components, and identifying any contributing factors to the recent failures. The following tasks outline the approach that will be used to support this assessment: The investigative procedures will consist of the below listed items:

1. Hydra will engage with a surveyor to locate and flag the areas where existing air release valves (ARV) should be located based upon as-builts and previous design plans in our possession.

2. Hydra will engage with a qualified utility contractor to expose the existing air release valves along the force main within the boundaries of the park and if needed, along the force main outside the boundaries of the park. Hydra will also request that the contractor expose the force main within the park in multiple locations to confirm the pipe size and type.

3. Hydra will make recommendations based upon the data received on the suspected cause of the failed force main and potential remedies to correct the conditions (minor repairs up to replacement of the existing force main within the park).

Subtask 1: Survey Description: Optimum (formally O’Neal) Surveying & Mapping, Inc. shall conduct a utility location survey of all known ARV (Air Release Valves) along the alignment of the existing sanitary sewer force main, both within the limits of the park and outside the limits of the park. Hydra will assist in coordination with FDEP and Wakulla Conty Public Works to gain access to the force main.

Deliverable: Consultant will provide electronic copies (AutoCAD and pdf) digitally signed and sealed of the utility survey.

Performance Measure: Deliverables will be reviewed by the Department to confirm they are complete, accurate, and timely. (Please do not alter this language)

Subtask 2: Subsurface Location Survey of Existing Sanitary Sewer Force Main within the Limits of Wakulla Springs State Park

Description: Tasks include a subsurface utility location survey of the existing sanitary sewer force main at 6 different locations (TBD) along the alignment of the force main. Blood Hound will flag 20-25 L.F. of sewer force main in each of the 6 different locations for excavation or potholing activities to determine the existing utility size and material.

Deliverable: Consultant will provide subsurface investigation narrative with attachments and .kmz files to project manager electronically in PDF format.

Performance Measure: Deliverables will be reviewed by the Department to confirm they are complete, accurate, and timely. (Please do not alter this language)

Total for Subtask 2: (Fixed Price Cost) = $2, Subtask 3: Sewer

Description: Hydra will engage with a qualified utility contractor to perform the ARV maintenance and testing (both inside the limits of the park and along the force main outside the limits of the park).

Hydra will direct the utility contract to expose the force main along the established route in 4 - 6 separate locations to confirm the pipe size a type. Hydra will also direct the utility contractor to excavate the manifold location where the lift station that serves the residences connects to the primary force main existing the park. Hydra will also consult with G.S. Preble as he is the original D.O.R. of the lift station and force main. G.S. Preble will perform one site visit to the park to review and evaluate the current conditions of the system.

Hydra will gather and analyze all available as-built drawings, maintenance records, and previous inspection reports related to the force main and lift station infrastructure to establish a baseline understanding of system. In addition, Hydra will perform hydraulic calculations to determine expected total dynamic head values of the existing system to compare to measured pressures within the system.

Deliverable: Hydra will provide site notes and a sanitary sewer investigation report in PDF format to the project manager.

Performance Measure: Deliverables will be reviewed by the Department to confirm they are complete, accurate, and timely.
