Rye: Elgan Avenue Coastal Bio-infiltration Basin
- Project typeDrainage and Slope Stability
- Project value$450,000
The Elgan Avenue drainage outlet in Rye had no means to routinely capture and remove litter. The drain discharges into a short open channel before discharging onto the beach.
A bio-infiltration basin is being constructed. This includes altering upstream drainage pipe, installing a gross pollutant trap and relevant inlet and outlet scour controls. Local species will be planted in and around the basin; designed to improve treatment and minimise sand movement. A boardwalk will also be installed to facilitate access to the beach and along the Bay Trail. Water quality modelling, hydraulic analysis, and maintenance concerns were considered in this design and the planting schedule reflects the desire to keep a natural feel. A level indicator was installed at the site to monitor sand migration.
Works on the basin are largely complete, with the bay trail boardwalk now open to the public for use, including direct access to the beach. Planting of the 11,000 plants required for the project has now been completed. Some local community volunteers were able to assist with the planting.
The Gross Pollutant Trap has been booked in by the contractors to be installed in May 2023 to complete the works.
Update: May 2023.
