New water station on west coast

Thursday 01 September 2022

Guernsey Water is ahead of schedule on the largest project of the year in its rolling programme of investment in the island's network.

The refurbishment of Grandes Rocques pumping station, situated in the grounds of La Mare de Carteret Schools, involves the construction and installation of a new wet well, valve chamber and kiosk.

The ongoing programme costs Guernsey Water around £600,000 a year and is normally focused on the installation of replacement pumps and station panels.

"The existing pumps and station will continue to remain in use whilst the new chamber and pump control kiosk are commissioned. The wet well chamber itself is constructed out of stainless steel," said Carl Falla, Capital Delivery Manager at the States-owned utility. 

"The wet well holds the pumps and acts as storage, allowing wastewater to build up before being pumped away.

"This is the most energy efficient way to run the pumping stations. It also provides extra capacity within the wastewater network, helping to alleviate the risk of flooding during periods of heavy rain."

Most of the work on the Grandes Rocques station is being carried out during the summer holidays. But it was always intended that the project would be completed after La Mare de Carteret Schools reopen to students next week. 

Guernsey Water said that customers have not - and should not - experience any disruption to water services during the refurbishment.
