AGENDA MEMORANDUM

Meeting Date: January 26, 2009

From:                          Raymond S. Sharp, Director Environmental Services/Public Works

Subject:                      Resolution authorizing an agreement with Boyle Engineering Corporation to provide design of conversion of a 20 inch effluent transmission main

Staff Recommendation:

Staff recommends approval of the agreement with Boyle Engineering Corporation to provide design of a 20 inch effluent transmission main for $33,064.

Analysis:

During the early 1980’s, the City constructed a twenty inch diameter effluent transmission main to convey treated effluent from the Canal Street Wastewater Treatment Facility to the north sprayfield for disposal.  Now that the plant conversion is completed and we are ready to supply reuse, the City will convert this low pressure effluent main to a reclaimed water transmission main which will convey reclaimed water from the Canal Street Plant at higher system pressures.

Several years ago, Boyle Engineering Corporation, under a separate agreement, evaluated the options for the use of this effluent line, its condition and serviceability as a reclaimed water transmission main.  The effluent line was found to be in good condition and serviceable, and could be converted to reclaimed transmission main duty at far less expense than construction of a new transmission main – being able to convert this main will save us in excess of one million dollars.

We are now at a point at which we must make the conversion.  There are three necessary components of the conversion:  first, the pipe will be lined with a cast-in-place liner at the crossing under US 441.  Second, the pipe will be lined with a cast-in-place liner at the crossing under US 27.  Third, a pressure sustaining valve will be installed in the line in Vine Street in the vicinity of College Street.  The purpose of the cast-in-place liners is to ensure that there will be no leaks or breaks which will disrupt either of the two major highways under which the line crosses.  The purpose of the pressure sustaining valve is to provide a mechanism to maintain pressure at normal system pressure service levels in the portion of the main which will be pressurized for transmission main service.  This will allow service to all of our major reclaimed water customers and the reclaimed water distribution system on Canal Street, Dixie, and US 441.

Approval of this agreement will provide the necessary design and permitting services, the necessary bidding phase services, and limited construction phase services for this project. 

Options:

1.  Approve the agreement as presented; or,

2.  Such alternative action as the Commission may deem appropriate

Fiscal Impact: 

Funding for the engineering services is available in the 2007 bond issue.  The construction phase of the project is also provided by the 2007 bond issue with a 20% reimbursement from the St. Johns River Water Management District.
