Installation of the replacement pipeline will likely take place from June to October 2022.
Construction updates will be provided to the local community at least two months before the installation works commence. We will agree how we communicate this information with local authorities.
The map above provides information on installation within the park. As outlined in the planning process, the project will be using a narrow working area through the park. Further information on our construction plans can be found below.
Before installation starts, the first thing you will see is signs notifying park users that works will be taking place.
When installation starts, Heras-type fencing bolted together, or strong-wall fencing, will be used to secure the working area.
You may also see mobile welfare units, equipment, materials and vehicles within the working area.
During the open cut installation process, you may see deliveries of the steel pipes. These will be brought to site in a ‘just-in-time’ delivery sequencing – this is because we want to reduce the space needed for the compound within the park. We will also have 24-hour security of the working areas within the park.
Public access to Southwood Country Park will be available throughout installation.
The undesignated paths within the country park will be crossed by the working area. However, at intersections between the working area and paths, pedestrian crossing points will be installed. Pedestrians will have priority at these crossing points.
The car parks used for Southwood Country Park will not be impacted by the works.
The local landscape character comprises of informal footpaths within grassland, hedgerows and trees. Works are underway to convert the area from a heavily managed amenity environment as a former golf course, to a country park managed for recreation and nature conservation.
Ahead of construction, trees and hedgerows identified have been removed by a team of specialists after advice from the Environmental Clerk of Works and the arboriculturist.
Gaps will be restricted to a maximum of 10m through hedges and woodland belts, and the woodland to the north near Cove Brook will be subject to narrow working.
We will be using tried and tested techniques to work around tree roots through the park, including hand digging and use of air spades.
In addition, the project’s Environmental Clerk of Works and arboriculturalist will visit working areas to provide specialist advice when any works to trees, such as branch removal, are required.
As we enter into the park from the south there is a potential veteran tree. It is within the Order Limits near the southern boundary with Ively Road, and it will be retained.
We will be using an open cut technique to install through the park.
We have committed to a narrow working width of 15m to the northern section of the works, incorporating an existing track to reduce impacts on woodland near Cove Brook.
Works in the Cove Brook Flood Storage Area will be scheduled to take advantage of long-term forecasts making use of dry weather conditions.
A 30m wide fencing/barrier system will be erected within the Order Limits, reducing to 15m through the narrow working section – this is to segregate the ‘live’ working area from public accessible areas. As the works progress, the fenced area will be relocated/extended so that no more than 150m of continuous fencing is in place before a public crossing point. Vehicle tracks and the plant haul route through the park will not be continually fenced – this is to allow open public access across the park.
Entrance gates will be placed at each end of the fenced ‘live’ working area to allow access for the team and equipment. These entrances will be closed and locked when not in use.
The open cut will be complete when the ends are connected into the pipeline installed using trenchless techniques. Therefore, depending on the sequence of the works, the end section(s) of trench will be suitably fenced off and secured until the connection of the pipe to the trenchless section is concluded.
We will be using an auger bore trenchless technique to cross below the A327 Ively Road. This work will likely take place from August to October 2022.
The launch area will be located on the west side of the A327 Ively Road, and the reception area will be located on the east side of the A327 Ively Road. The trenchless areas will be topsoil stripped and neatly stored to one side of the trenchless area, which will provide additional noise and visual screening of the area from users of the country park. The area will then be covered with a permeable surface or protection matting.
The area will be fenced with a 2m high perimeter fence that is bolted together for security and placed on rubber weighted feet for stability. The public facing façade of the fencing will be in accordance with Rushmoor Borough Council’s design/requirements and will include project information and safety notices.
We will be using a pipe pushing trenchless technique to cross below the Cove Brook Dam. This will likely take place in June, July and August 2022.
Launch and reception areas will be constructed either side of the existing dam structure. The launch area is to be located to the west of the Flood Storage Area and will be serviced from this direction.
The pipe will be pushed from west to east (Southwood Country Park SANG to Cove Road) into the reception area. The excavation will remain open for as short a period as possible but will only be concluded once the open cut pipe installation has been tied into the pipe pushing section of pipe.
The areas will be topsoil stripped and neatly stored to one side of the area, which will provide additional noise and visual screening of the area from users of the country park. The area will then be covered with a permeable surface or protection matting.
The Pedestrian Paths
The paths will be reinstated once the open cut installation is complete. Details will be in agreement with Rushmoor Borough Council.
Vegetation will be reinstated as shown in the reinstatement plan.
Where the topsoil has been stripped and stored adjacent to the excavation, this will then be replaced after the works have been completed and either seeded with an appropriate conservation seed mix, previously collected seed or left for natural regeneration, following discussion with Rushmoor Borough Council’s Ecology Officer and informed by the updated surveys.
Hedgerows will be fully reinstated, and areas of woodland will be fully reinstated with a mix of appropriate native trees and woodland shrub species to the west of the A237, while in the Cove Valley Southern Grassland and Cove Brook Grassland the removed trees will be reinstated as acid grassland. The crossing of the Ively Brook will be reinstated to a more naturalistic structure if this has not already been achieved by RBC at the time of construction.
Construction access will be from Ively Road, Cove Road, and via Cove Cricket Club Grasmere Road. At the midpoint of the country park is construction compound 4AC which facilitates the works.
The work areas will be fully secure with locked gates and 24-hour security.
