Transport and Technical Services (TTS) has published its waste water strategy outlining plans for the next 20 years or so.
The main focus of the strategy is the need to replace the sewage treatment works (STW) at Bellozanne. The plant was built in the 1950s and is now struggling to reach the required standards. It is inefficient and outdated and is continually requiring costly maintenance, and it can’t cope with increased flow from the drains when there is heavy rainfall.
Over the years, it has been refurbished and repaired but studies have shown that this is no longer feasible and the whole plant needs replacing at a cost of £75m. This expenditure is essential to ensure that:
- the STW achieves current and future discharge standards
- there is minimal risk of partially treated sewage being released into the sea after heavy rainfall
- the plant is much more efficient and is not prone to breakdown or complete failure
Jersey's sewerage network
The strategy also looks at the sewerage network (the sewers and drains that collect and transport sewage to Bellozanne for treatment and surface water to the sea). In order, the priorities are:
to repair and refurbish the sewerage network
to continue to undertake projects to install new drains so that the surface water is separated from the sewage. This reduces the amount of water that does not require costly treatment from going to Bellozanne and allowing it to go straight to sea
to connect appropriate properties to the network that currently have no connection
Council of Ministers has lodged the strategy as an appendix to its report and proposition which is due for debate in May. It also includes a call for the Minister for Transport and Technical Services to develop a strategy for helping householders to connect to the public sewer network more quickly.

TTS has produced a video to explain the need for investment in the waste water strategy.
