THIS VIDEO
This ongoing Video Diary by myself John Neal, sometimes known as John Longcroft-Neal, as the whim takes me.
TODAY’S SUBJECT is very special since Mr Burt Pickering project manager from Severn Trent Water of the Hinckley to Hartshill sewer pipe line gave me a full tour of the works and answered all the questions I think you might have asked.
GENERAL STUFF
I am retired from two careers of primary school teaching when I was deputy head of a Middle School and Primary School, and as a self employed Chalkboard Artist from 2002 until I reached the grand old age of 65 in 2016. Since I retired it’s like a second childhood but with more expensive toys.

I play guitar and write songs and have written about 14 songs for the local BBC radio station. I run a weekly (weakly) evening Acoustic session at a local pub and have been doing so for 14 years now. I also started an afternoon acoustic session in a quite large cafe in Nuneaton. Both premises were former songwriting clients of mine.
Much of the music I use on this channel is taken from epidemicsound.com free to use on Youtube for a reasonable monthly fee, and sometimes I suffer you with my own music.
Gear that I use:
DJI Mavic Mini 3 Drone.
Iphone 15 Pro for camera, generally front facing so I can see myself in frame. Super quality especially if I keep the lens clean.
Go Pro11
Gimble is a Q2 Smooth by Zhiyun, I ought to use this more often because it was expensive.
Canon G7mk2
Sony IC recorder
Omnidirectional Lavalier Microphone
Rhode videomic to do voice over on computer
Video editing with Final Cut Pro X
Polarduck Mini Tripod for mobile phone. This is so good and under £10.00 I bought two.
Lamcou bendy leg tripod
Smatree Tripod / mono pod
Mono pod is a Manfrotto Compact MMC3-02 and is very useful for getting high angles that look like low flight drone shots and so easy to carry on my bike along with the mini tripod.
My bike is a e28 Estarli electric bike.

Good morning it’s John Neil here it’s Thursday the 15th of February 2024 and I’m really excited because I’ve got a chance to go and view the major engineering works of the sewer line that they’re putting from hinley to Hartsville great let’s go right I’ve arrived at Wedington Lane
Depo I’ve parked properly I hope uh just go over to uh reception here we go the abandoned Railway is running along there yeah we’ve got gravity pip workk coming along just the other side of that hedge line yeah and then we’re going to cross under the road here and
Pass all the way down there then it takes a bit of a dog leg right down the bottom we’ll drive all down there later um down to below ckut Village yeah and then under the river anchor so yeah right I got some hi hopefully this will all fit you right should we do
It this is Mr Bert Pickering the seven Trent project manager for this pip and he’s very kindly offered to give me a tour of the site in here um for the storm water that are going to act as buffer tanks and then the left hand side if you see all that basically that
Wasteland that’s going to all be profiled and created into big lagoons yeah they’ll all be naturally clay lined and everything like that so they won’t be just big concrete tanks as such you know what I mean I was so very impressed with this engineering work we’re using the pipe
Jack technique for the three times that we cross the A5 as well as under the railway yeah and then we’ve got all the small water courses and um we’re using the horizontal directional drill which you’ll see a bit later on cuz we’re currently doing it under highz College
Drive you actually look here there the gentleman with the transponder so see the gentleman he’s got a transponder and he’s walking with the head of the drill to track its height and direction to guide it to the right place the other side where we wear access point yeah
Yeah this a big if you look it’s just going on a new shaft onto the drill yeah so you’ll start off with 4 in and you go six and you go eight then you go 10 then you go 12 until you’re big enough to then when you’re at the other side you
Can pull the the pipe through the hole you’ve created sure oh yes see what I mean by being offset yeah get a bit closer so that’s probably the final rer I’d say before we then pull the pipe they’ll get all welded up cuz they wear away they just Rew them that’s so those
Those the patterns on it yeah a bit a bit exotic yeah yeah AB original yeah so using one called an aore we’re on the disused railway and also the a tri4 we’re driving on now so that’s a basically a big screw it will draw drive under the road
And it’ll be done while the road’s still open and uninterrupted as well so yeah and then the pumping station is being built over there yeah and then so the plastic pip work will come along that edge down here and then it’ll go down the shaft and along the tunnel and then
It will come up the other side well we call it access point 3 but that where the TBM is just on the edge of the A5 good there you go there’s one of the tunnels it’s like a mini Euro you know how they did the Euro tunnel it’s basically a mini version of
That the best way to describe it look on the back end of here you’ve got a frost wall Yeah so basically the idea is you see we’ve got the Rings for the tunnel here yeah so what happens is they’ve got B on the outside of the
And you’ll slot a ringing behind the TVM yeah and then you push the TVM with the ring and then once you’ve done you pushed it the length of the ring you then um pull the Jacks back put another ring in and push again do you know I
Mean so yeah that’s the idea behind it but we’ll start at hly Works cuz we’re building a big pumping station at hle works as well as we’ve already started laying the um concrete gravity section there yeah um and then also from yesterday we start not from yesterday from Monday the
Another contractor started on site to build the new um storm treatment Wetland there so um part of the reason we’re transfer into heart sh stream works is because inle um um basically discharging to a really small water course so yeah the detriment onto the water course is far
Greater um so to improve the sketchy Brook which it currently discharges into that goes through hinley yeah um we’re moving it to a bigger works like heartsill where we can do a lot more of an industrial treatment process and make the water quality better yeah um so
That’s the plan but what we’re also going to do is in range scenarios instead of it directly discharging into the water course which I’m sure you’ve seen in the controversial yeah yeah yeah um we’re basically building a big Wetland solution there which is basically we’re going to have four
Massive big lagoons full of plants and I’m with you I know yeah so it’s it’s one of the first in the country I believe I don’t really have much to do with it a colleague it looks out of the Wetland but um so the idea is instead of
It discharging straight into the warh course it’s going to discharge into the Wetland and those plants are going to take all the bad stuff out of the sewage and hopefully mean that we’re going to have a lot more of a better effect on the local environment that’s the plan so for instance with
Heart seal series treatment works um they’re doing they’re spending there nearly as much money as his transfers costing on expanding the world it’s nearly I can’t remember I think it’s nearly about 50% larger in capacity than what it currently was and that’s to take obviously all the growth in the
Heart seal catchment so that’s all of none eaten in heart seal Village and stuff like that and then also the flows which are going to come from hinley as well so it’s going to be a far more of a robust solution there as well but like accumulatively between the Wetland the
Transfer and the expansion works at heart so it’s well in excess of over 1220 million of investment so this is all this roundout here is where it turns from plastic twin plastic pressurized Rising man right got you into gravity I’m yeah so it’ll gravitate all the way from the right hand side of
This roundabout as we look at it now all the way down to a new pump station we’re building it cut Village um so where it’s rising main the other side of the road on the left we’ll come back once we’ve been to H we can actually
Drive down the hall Road and see it being laid cuz they’re currently laying it down there but that’s pressurized all the way from Hinkley Su streamworks all the way to this roundabout wow and then this will be pipe jacked probably I don’t think the depths are completely
Finalized but between 8 and 10 m deep yeah under this roundabout diagonally and is this Major Works because of um all this housing is that a factor involved or is it just major pretty much the majority of it is due to improving the quality of the sketching
Brook that’s the main driver I got you for the whole job yeah if I’m honest so um and obviously you’re um none eaten in heart till catchman growth yeah so which must be considerable CU there’s all these yeah thousands of well a lot of this all it seems really stupid but how the
Network works a lot of it will be pumping to hle works and then joining the transfer at hle works and coming back back here yeah yeah so you can see sort of just the raised part that’s where the two pipes are now in the ground yeah um I’m
Hoping we can show you the bucket they used cuz we had a specially made bucket made that was the exact profile of the trench so that we could um do it in one scoop almost that’s we’ve got a special um bucket that’s um designed for that exact shape the joint
Yeah there’s a joint Yeah so basically you don’t get too the Ed um you basically we Mount both ends yeah with a big hot plate in the middle and then you lift out the hot plate and push them together and then they um cool down together and fuse B just W weld itself
Together yeah got Fusion Wells yeah What’s the total distance from 13 and2 km really yeah I didn’t mind it was less than that no yeah so yeah it’s um it’s about 4 and a half to 5 km of gravity and then the rest is rising L yeah so total
Cost around all three of them together it’s north of 120 million wow so that’s with Wetland transfer and the expansion works at hard yeah and so what’s happening at hardill works that’s so that’s all expansion and improvements to the treatment process so heart seal they’re going to they’re expanding it
For all the expansion that’s obviously going on in that catchment with Nita and in haril and then also the flows which he’ll be receiving from from hinley tell me a bit more about those um Wetland areas over at hinley that’s fascinating that yeah so we’re triing it’s going to
Be sort of on this scale anyway probably one of the first in the country where we’re going to um going to treat the storm effluent so I’m sure as everyone’s aware currently in the news the all the water comes into the country get a bit of a taling
Off discharg walk so what we’re trying to do is eliminate that really so we’re going to um build a big Wetland at Hinkley um in the space available so that in a storm event all that effluent goes to Big lagoons basically and it’s all treated for a natural solution with
Plants and trees and stuff like that and yeah it’s what size was it again it’s I think last time I saw a design it was about 40,000 square m right so but yeah um it’s going to be a big old big old thing yeah and and you say the pipes
Are going to be working at the end of this year yes so we’ve got an obligation date to meet of the 21st of December so that’s where flows will be on fingers crossed but all the other works still yeah so we there’ll be like we’ll probably have to wait until the dry
Months in 2025 for reinstatement of top s and stuff like that um but yeah it’s hopefully the majority is going to be done in this year to be honest so how many people are working on all those do you think it’s a good question I’d say
North of 100 yeah got to be yeah north of 100 we got a lot of lot of gangs we’ve got six gangs on the gravity pip workk we’ve got a gang on the uh Rising Main and then we’ve got four five six tunneling gangs as well so and so of all those projects
Within this big project which you think is the most challenging well I’d probably say my one to be fair so I’m responsible that that one I’m resp yeah indeed it’s a big it’s the stakeholders as well do you know what I mean that’s probably the um most challenging part about this job because
We’re crossing everything under the sun like we’ve got Network rail canal and River trust highways England um EA with all the water courses we’re crossing yeah um and about I think that’s just sh of 30 land owners yeah as well we’ve obviously some have got developments and
Stuff like that as well so the logistics of coordinating all those people yeah and obviously as everyone I suppose has seen in the last couple of months the weather has been yeah pretty diabolical but go on so but of the uh the civil engineering which is the most challenging you think they’re telling
Um yeah tunneling in the gravity that’s the um biggest challenge is like plastic with it being pressurized you’re not um you don’t have to be as not accurate probably the wrong word but it’s not as temperamental to Del lay should we say um and it’s not as deep excavations either
So yeah it’s um especially with gravity as well you’re doing 2 and 1/2 M lengths instead of 12 M so it’s a bit more time consuming yeah sure and you got to get the levels Bob on so you’ve got fall on the gravity sections but I’m going to finish it
There thank you terally for this opportunity has been really useful informative and I should do my best to pull all this stuff together now maybe we come back in a couple of time and see how it’s going yeah yeah and present it to uh the the inquiring public yeah yeah
We see grilling I get no not at all it’s h it’s terrific and um it’s great opportunity to find out um well yeah and if there’s any questions that come out of it all you got to do is drop well they’ll be in the comments underneath be able to do that yeah
Excellent thank you very much uh big round of applause there to Mr Bert Pickman from Seven Trent for giving us that fantastic talk around the pipeline that’s going he heart thank you very much indeed and uh if you got any comments any further questions that I
Can put to ber later on then put them in the comments below otherwise guys you will see me in the next video bye-bye

Very good video John Very informative keep up the good work.
Nice to see you in Town the other day. The Premier has arrived ,had to watch it on my TV. Well what can I say absolutely Brilliantly informative ..One if your best if a my say .Keep um coming .lol. Regards.
Excellent!
Hi John that was excellant so good of the gentleman to show you around. The pressurisation method explains my query on how to get an uphill flow. Did he explain how they pressurise the pipes and how is the transfer done from a pressurised to non pressurised part of the system?
Quite a scoop John and nicely edited.
