20-058 - Alcaniz Street Outfall to Pensacola Bay Stormwater Treatment Enhancement Project

The purpose of this project will be to provide stormwater treatment for one currently untreated drainage sub-basin within the Pensacola Bay Watershed. This treatment will be provided by fitting the underground stormwater conveyance system with a proprietary underground treatment unit and associated manholes. This project is consistent with current technology for stormwater retrofit treatment and is part of an ongoing program utilized throughout the City to improve water quality of area waterways. As a result of these improvements, work site safety, MOT, maintenance/bypass of stormwater flow, dewatering, and erosion control will be paramount issues.  General work to be accomplished will include installation of new Vortech unit, significant dewatering, storm structures, new storm pipe, curb and gutter, and sod.

Additionally, as depicted in Sheet C-5 of the plans, the storm structure at the intersection of Alcaniz and Government Street is old and has some leaks in it. The entire interior surface area of this structure is to be wiped with cementious grout as per the Manhole Rehabilitation specification.
