Keswick flood alleviation scheme

Keswick flood alleviation scheme

Penrith Road Flood Alleviation Board (PDF 4MB)

The project, which is being led by Cumbria County Council will address surface water flooding issues at and between the Penrith Road and Ambleside Road areas of Keswick. The Council is planning to construct a new flood storage attenuation pond on land at Springsfield, a new pumping station within, or adjacent to, Penrith Road, (discharging into the River Greta), and, where necessary instigate property level protection measures to properties between Ambleside Road and Penrith Road. The scheme will protect up to 118 properties at risk.

We have now completed coring through the existing flood wall on Penrith Road. This allows for a new outfall from the pumping station to the river. You can find out more about the work at ur biweekly drop in sessions at Keswick library.

Work is progressing well with 95% of the Castlehead drain now relined and flowing and the Springs Road temporary storage basin excavation is complete.

High levels of rainfall before Christmas provided the first real winter test for the new temporary storage basin at Springs Field which successfully collected and held water from the surrounding catchment. Water is being managed from the basin into the drainage network whilst the new outfall and headwalls are constructed in the next two weeks.

Whilst the pumping station chamber in Penrith Road is now fully excavated and the concrete wall is poured, the late December rainfall has hampered access to one of the manholes which is to be reconditioned. The road closure is now due to be lifted and managed under subsequent traffic lights by the 19 February.

Construction of the blockwork for the new control station kiosk and bus shelter will start in the coming week.

Thank you for your continued support and patience whilst we carry out this essential flood prevention work to protect homes in the area.

Due to the recent rainfall, the newly constructed basin at Springs Field has filled with water. However once it is complete, this will typically be a dry basin with only a small stream in the middle, but because there isn't a connection to the newly refurbished Castlehead drain at the moment, it isn't draining. Please don't be concerned about this as we have earth bunds in place and are closely monitoring the situation.

The pumping chamber which sits underneath Penrith Road is now cast in concrete and looking lovely! This will house the pump which will discharge water in to the River Greta at a rate of 350 litres per second, which is pretty impressive!

Our contractor has made excellent progress digging soil out of Springs Field for the storage basin which is now close to being the final shape and depth required. There's still a good amount of earth to leave the site and we thank residents for their patience whilst there are increased vehicles in the area removing the soil.

Key drainage connections between the new temporary storage basin at Springs Field and the River Greta are nearing completion, and contractors are working on the construction of the pumping station and control kiosk in Penrith Road.

During the excavation for the pumping station on Penrith Road, contractors discovered a United Utilities water main under the road surface, which required a diversion. In addition, discovery of a number of large river boulders are taking time to remove due to the limited working space. Unfortunately, this means a delay to the project, which will likely extend the closure of Penrith Road until the first week of February 2020. 

The team have considered several options for dealing with the delay. However, following careful consideration, the council has decided that the preferred option is to keep the road closed during the Christmas period until the first week of February 2020.

Drivers will be able to follow the current diversion system via the Crosthwaite roundabout and advance signage will be maintained throughout the schedule of works.

Drop in sessions continue every Tuesday between 10am and 12pm at Keswick Library for members of the public.


7 November 2019

Work is progressing well on the £ 2m Penrith Road flood alleviation project.

The main works in the allotments are now all complete, with the new filter drain, pipe connections and manhole all in place. Construction work to connect the new pipes to the Castlehead drain will start next week and are expected to take around ten days to complete.

The main excavation works at Springs Field will start tomorrow (7 November) with earth beginning to leave site next week. Residents and visitors should be aware that there will be increased vehicle movements in the Springs Road area for the next two weeks as material is removed from the field to enable the construction of the flood storage basin.

Excavation and piling works are continuing to progress well on Penrith Road at the site of the new pumping station. 

Don't forget that drop in sessions are held in Keswick Library every Tuesday between 10am and midday where people can pop in to find out more about the project

Springs Field

The site compound has now been built on site and ground works have begun to remove the top layer of soil. The location of the basin is now marked out.

On 2 October work started under the allotments to connect the Castlehead drain to the new basin. 

As part of this process we are using a new innovative material to re-line the drain pipe, which will strengthen and future proof it. This technique will prevent additional disruption as it can effectively be done from one site rather than having to dig along sections of the drain.

Penrith Road

Excavation work for the pumping station has now started, and the old bus stop has been taken down ready for the new local stone and slate built kiosk to be constructed.

Works to divert the underground services has taken place and working to strengthen the walls housing the pumping station will begin soon.


17 May 2019

Planning applications to commence construction works have now been submitted to the Lake District National Park Authority. Details of the applications are available to view below:

Two drop in sessions have now been held, with over 100 members of the local community attending. The feedback on the proposal for a pumping station has generally been very positive.

As part of the scheme, a new kiosk is required to hold all of the control equipment for the pumping station. This kiosk will be built from local stone and slate to in keep with the local buildings, the new kiosk will also incorporate a new bus stop.

Feedback on this through the consultation phase was very positive.

Some concerns have been raised regarding the visual impact of the gates and access track to the field where the flood basin will be situated - including concerns over access and road debris during the construction phase.  Some concerns were also raised regarding the privacy of adjacent properties during and after construction of the basin.  Here is a summary of those concerns:

  • The gate was set too far in to the field so may become a parking space on an already busy road
  • As the gate is set back in to the field, people would have a line of sight in to nearby properties at the top of the field
  • Removal of mature hedges and replacing with saplings
  • Filter drain to catch some of surface water flow located too far away from property boundaries

Proposed basin image

Following the drop in sessions, the council has worked alongside designers and local residents to develop a new design which meets the requirements of the project, whilst taking the views and concerns of the community in to consideration. Here is a summary of the revised design following community feedback:

  • Move gate to the north as close to property boundaries as possible to reduce line of sight in to homes
  • Plant additional hedging to provide more screening
  • Bring the gate closer to the road to prevent parking
  • Move the filter drain to the field boundary to catch more surface water
  • Where possible plant mature hedging instead of saplings, and reinstate removed hedges elsewhere where possible
  • By moving the gate we will be able to reduce the amount of hedging to be removed
