Re: WWTF Digester Improvements
City of Tybee Island
Letter Agreement for Services
Dear Ms. Schleicher:
Thank you for requesting our engineering services for the digester improvements at the
City of Tybee Island Wastewater Treatment Facility.
The City has a need for additional biosolids treatment and management at the
wastewater treatment facility. After a preliminary review of options by Thomas & Hutton, the City
has decided to move forward with a new aerobic digester to assist in treatment and reduction
of the biosolids within the facility. The project will include a new 65-foot diameter by 16' foot
deep pre-stressed concrete tank with additional blowers and aeration diffusers, electrical
upgrades, and piping to existing sludge return pumps.
Our services will consist of the General Consulting Phase, Survey Phase, Design
Development Report Phase, Design Phase, Permitting Phase, Bid Phase, monitoring during the
Construction Phase and Closeout Phase, as set forth in the General Provisions, supplemental
exhibits, attached hereto, and such Additional Services as you may request during the course of
the Project. We understand that you will furnish us with full information as to your requirements,
including any special or extraordinary considerations for the Project and will make pertinent
existing data available to us.
Payment for our services will be as described in the attached General Provisions. You will
be billed monthly for our services rendered and for Reimbursable Expenses.
