Van Oord bicycle is on its way to Africa

One of Van Oord’s bicycles used during this summer’s Guernsey Water outfall replacement project has been donated to The Eleanor Foundation’s Bikes to Africa project.

These familiar bright orange bicycles were used by Van Oord staff as a means of efficient and pollution free transport from its temporary office on North Esplanade to and from the Harbour and outfall replacement site at Les Banques.

Completion of Guernsey Water’s sea outfall replacement project

Yesterday marked the completion of Guernsey Water’s Wastewater Centre project, delivered over the last ten years.

On Wednesday 18 November, Guernsey Water hosted an event at the Belle Greve Wastewater Centre attended by a number of deputies, civil servants, local residents, environmental groups and consultants involved in the project and representative business groups.

Here Deputy Scott Ogier, minister of the Public Services Department officially unveiled a plaque to commemorate the completion of the sea outfall replacements, the final phase of the overall project.  

Pipe bridge dismantled

The temporary steel pipe bridge that has been spanning the road at Les Banques, was dismantled and removed from the site last night (Tuesday 13 October).  The pipe was in place as a precautionary measure to provide a temporary pumping capacity should there have been a particularly heavy rain fall filling the storm tanks at the Belle Greve Wastewater Centre while the short sea outfall pipe was out of commission.

Outfall replacement project on schedule

Guernsey Water’s progress on the final phase of the £35 million upgrade to the island’s wastewater facilities is on schedule for completion at the end of this month.

Both the new long and short sea outfall pipes have been floated into their final positions and connected to the onshore pipes as they exit from the new chamber constructed close to the Red Lion slipway.

Why did Guernsey Water need to replace the existing outfall pipes?

Temporary traffic lights at Les Banques

Temporary traffic lights will be in place at Les Banques for three weeks from Monday 24 August as part of the vital ongoing Belle Greve outfall replacement project.

A single lane traffic light system will be in operation initially on the northbound carriageway before switching to the southbound carriageway which is likely to cause disruption to vehicles during peak commuting hours.

Guernsey Water would like to apologise in advance for any disruption this is likely to cause road users.

Outfall contractor helps to reduce rock height in harbour

One of the specialist vessels working on the outfall replacement has helped reduce the height of a rocky outcrop at St Peter Port Harbour. 

The 52-metre long barge, Razende Bol, has been used to dig the underwater trench for the new long and short sea outfalls.  However this week there has been a pause in the offshore excavation work, while the pipework is being laid.
