3. Project description (100 words or less)

Existing plant has been in operation for over 40 years although it was upgraded in 1985. The plant is reaching it's organic design capactiy of .49 mgd. Proposed new plant consists of two .5 mgd package plants built in parrallel train.

1. Effluent quality is a constant concern because the wastewater discharge point is located in Aloe Bay which influences the oyster reefs around Dauphin Island. The Dauphin Island water & Sewer Authority project proposes to meet the 5-5-3-1 parameters for its effluent that is currently being enforced in Florida at the present time.
   1. The Dauphin Island Water & Sewer Authority's discharge permit is currently being renewed by the Alabama Department of Environmental Management for the proposed new plant. Although ADEM representatives have assured the Authority that the new regulations will be more stick than the present permit limits, they will not be as stick as the 5-5-3-1 regulations the authority is targeting. In order to eliminate effluent discharge into Aloe Bay the Authority has also requested that ADEM include parameters for surface application of the effluent for irrigation at the local golf course. The Authority estimates that 90% of the effluent during the year could be sent to the golf course. The present discharge point could not be entirely eliminated because the holding pond at the golf course fills to capacity during heavy rain events.
   2. The Authority is proposing two ,5 mgd package plants instead of one 1.0 mgd plant in order to provide some redundancy in case of equipment failure and to have the capability to take one plant off line during low flow periods for maintenance.

The Dauphin Island Water Authority proposes to place bids on the market by mid February, 2000, for a design/build contract that will include two.5 mgd packaged wastewater plants with the capability to meet the 95% removal of BODs, 95% removal of TSSs, 97% removal of Nitrates, and 99% removal of Phosphates regulations currently being enforced in Florida. Included in the proposal will be plans to be able to reuse the sewer effluent for irrigation at the local golf course. The plant will have to be designed and built on a very small footprint and at the same time the existing plant will have to continue to operate in a satisfactory manner. The Authority has applied for State Resolving Fund monies and conventional financing. Any Federal or other State funding could be instrumental in making this project possible.
