The construction phase of this project is now complete.

There may still be updates, so the project will remain here. We are still monitoring the project and will reply to any comments. So if you have any questions please feel free to comment or contact us here.

EEL PROTECTION SCHEME

River Bure (Belaugh)

The Eel Regulation Compliance project at the River Bure in Belaugh is for installation of eel friendly screening equipment at our abstraction point on the river. The work is driven by the need for Essex & Suffolk Water to comply with the Eels Regulations (2009) and will improve the biodiversity value in the River Bure.

Project updates

Update by Nicola Wigington

The new screens are fully installed, commissioned and have successfully passed through a 28 day trial period. The screens are operating really well and so far haven't experienced any heavy loading of debris so the cleaning system is only being called to operate on a timed basis, twice per day. We're really pleased with the performance and will continue to monitor it and optimise the process so it operates as infrequently as possible.

The site has now closed down for Christmas but we will be returning in January to complete the groundworks inside the compound area and remove the old drum screens from the pumping station site. The majority of site-based works should be completed by the end of February.

I wish you all a safe and happy Christmas and New Year!

The screens and infrastructure are now in place and the screens will be tested over the next few weeks while we optimise the cleaning cycle frequency. It’s the perfect time of year to be doing this, with most trees shedding their leaves now there’s plenty of debris in the water to give the screens a real test in the most trying conditions.

The attached photos are from the installation phase, you can see the mini crane used to lift the screens in and the dive team in the water carrying out the final fix. The screens themselves are totally submerged so what you can see above the water are the tops of the supporting framework and the floating boom which will maintain separation between the installation and passing river craft.

The team have worked really hard in some challenging weather conditions in the last few weeks and have taken care to smooth out any ruts caused by vehicles tracking across to the riverside site but there will be muddy patches left behind for a while in these wet conditions, please take care if you’re walking through the field. The grass should quickly return over these patches in the next growing season which will return the field to its normal condition.

We have a busy couple of weeks ahead of us with the divers coming to site late this week to install the screens into the river. There are likely to be a few more people on site than you may have previously noticed and with that in mind we'll be taking extra care to work within the government's construction guidelines for Covid-19 and keep distanced appropriately. With the additional activity you might notice a bit more noise during this period while the new screens and the wash system are being put through their paces but this will only be during normal working hours. I'll share some more photos of the site progress in my next update.

More good progress was made on site last week. The kiosk was installed first and the control equipment was placed inside on Friday. Electrical connections and testing will follow.

The infrastructure needs to be finished before the eel screens can be installed but if progress continues to remain on track the screens should be going in at the end of this month or early October. That activity will be weather-dependant as it will involve a dive team working in the river.

Feedback on the recent archaeological investigations has been received and it appears to be most likely that the flint wall was part of an old drainage wind pump, as the historical records suggested, although no dating material was recovered during the investigation to provide solid proof. Historic maps of 1879 and 1881 show a wind pump slightly to the east of the location of the wall but close enough that it may have been directly associated. The drainage pump did not feature on the 1905 OS map so it had likely disappeared long before the modern intake was created (approx. 1960s). The original Mill was probably similar to the Boardman's Drainage Pump, details of which can be viewed on Wikipedia at the address below:

The archaeologists are still working on their final report so I'll feedback on that once we receive it.

We've continued with the civils works on site, the piling went well and the steel framework to support the new kiosk is being manufactured so will be delivered to site soon. The same team are working on a related project on the River Waveney in Suffolk so across the two sites they've made really good progress.

The attached pictures show the recent piling activity in action.

We haven't had the full report back from the archaeologists yet but Norfolk County Council have reviewed it and given us the green light to continue with the piling works next week. The piles have been re-sited so they won't interfere with the flint wall in any way. The piling is now planned for Thursday 16th and Friday 17th.

This week the team have continued on grounds preparation works and installing some ducting. They had a fabulous view of the river today with the sun perfectly placed for a mirror effect. There are definitely worse places to work!

The piling works were due to be completed this week but were put on hold when the team spotted an old flint wall at the edge of the excavation for the preparatory works. We called in some archaeologists to take a look and assess the findings. Norfolk heritage records indicate it to be the remnants of an old drainage mill, possibly from the 19th century but we'll wait for the archaeological report to verify this. In the meantime, the team have moved the excavation and the planned location of the piles away from the wall to avoid causing any damage. The piling has been rescheduled for the week beginning Monday 13th July, pending the outputs of the archaeologist's report.

Works are starting this week on site establishment, setting up a welfare area within the grounds of the pumping station and preparing for the piling works which are due to start in the week commencing 29th June. The piling will create a foundation to support the new control kiosk and there will be three piles installed. The work will be done during normal working hours and is expected to last a maximum of two days. There is likely to be some intermittent percussive noise while the piles are driven in (similar to the ground investigation borehole works that were done in January). Our installation team will aim to keep any disturbance to a minimum and the piling technique chosen for this job is 'bottom driven' which is a much quieter method than traditional top hammering techniques.

Site establishment will begin at Belaugh in a couple of weeks' time (from Monday 15th June). The welfare and storage area will be set up at the Pumping Station site. At the river, preparations will be made for the piling works which we expect will start towards the end of June. More details will follow when the dates are confirmed.
