Authorization
REQUEST: Utility Department Requesting Approval to Designate Shelley's Environmental
Systems as a Sole Source for hauling liquid Domestic Wastewater Residuals
PURPOSE: Utility Department Requesting Approval to continue using Shelley's
Environmental Systems for hauling and disposal of liquid wastewater residuals at
a cost of .065 cents per gallon
CONSIDERA TIONS:
This agenda item is needed to continue to dispose of domestic wastewater residuals as required
by the City of Winter Springs East and West Wastewater Operating pennits issued by the Florida
Department of Environmental Protection (FDEP). The East and West Wastewater Treatment Plants
each are required to have Agricultural Use Plans for Domestic Wastewater Residuals (sludge).
The City Commission previously authorized Shelley's Environmental Systems as the City's
domestic wastewater residuals hauler on November 13, 2006, under Consent Agenda Item 402, by
piggybacking off of the Toho Water Authority bid. The City Attorney has advised us that recent case
law requires piggybacking bid awards to be substantially similar and not a starting point for
negotiations. Since Shelley's has agreed to a lower price for our sludge hauling, piggybacking is not an
option in this case.
Since Shelley's Environmental Systems is listed on City of Winter Springs DEP operating
pennits as our residuals hauler, they are a sole source. They also have the contracts with owners of our
Agriculture Use sites which are permitted annually by the DEP. The cost for sludge hauling will
increase $0.039 per gallon to $0.065 per gallon for liquid. Cake sludge will increase from $20.09 per
yard to $26.59 per yard. Cake sludge only represents 5% ofthe $175,000 budgeted annually for sludge
hauling. The City of Casselberry has contracted for these same rates.

The wastewater plants generate sludge that is predominantly hauled off in liquid form (4% to
5% solids), however, we do occasionally utilize the vacuum beds and/or sand beds to dewater the
sludge which is then in a cake form (12% to 15% solids). Both solid and liquid residuals are disposed
at specific sites (typically sod farms) managed by Shelley's Environmental Systems in Osceola,
V olusia, Sumter, and Seminole counties. The wastewater residuals requirements section of the West
operating permit is attached as an example. Approximately 500 tons (dry weight) of wastewater sludge
is generated each year.
The City has been contracting with Shelley's Environmental Systems (previously known as
Mid-Florida Environmental) of Zellwood for over 12 years. They provide comprehensive annual
reports for the disposal sites and are in full regulatory compliance.
FUNDING:
Funds are budgeted in the Utility Department line code 3600-54320.
RECOMMENDATION:
It is recommended that authorization be granted to designate Shelley's Environmental
Systems as a Sole Source for hauling liquid Domestic Wastewater Residuals at a cost of $0.065
per gallon for liquid and $26.59 per yard for cake sludge.
IMPLEMENTATION SCHEDULE:
Sludge Hauling will continue at the new prices.
