#365daysofbiking A total bore

Thursday February 18th 2021 – Haring around Chasewater dam on a working from home exercise ride – for once in the daylight – I nearly came a cropper.

I was a shade off catching my pedal on this protruding piece of steel pipe.

It has a close fitting cap and is padlocked shut.

This erstwhile cyclist and walker boobytrap is not some idle lump of former mining equipment stuck in the ground, or a piece of scrap the local tatters have missed – but a monitoring well for the land around.

Ground engineers monitor the area around Chasewater Dam for groundwater pollution and signs that the dam may be leaking. To do that they have a number of these bores, drilled and sleeved, which are dipped and monitored regularly for changes in water level and the chemical composition of the water within.

These are a familiar sight around Chasewater, but also many of the public open spaces in the area that require ground monitoring – like Brownhills Common, Shire Oak Nature Reserve and Clayhanger Common.

So mind your step and watch out when cycling off road: They are quite sturdy and not very forgiving…

#365daysofbiking Stone me

February 1st – Heading out to for a gentle spin and resolving to take it a little easier – after all, I’d now got a cold developing which seemed to feature a particularly unpleasant mouth infection as a side dish – I bumbled past the monitoring well sensor post by Pier Street Bridge in Brownhills. Something on top caught my eye.

A beautifully painted smile stone.

There’s a local culture (particularly in Clayhanger in recent years) of painting random found stones with patters, cartoons or any art you fancy, then hiding them for smile stone enthusiasts to find.

Frequently this is a fun activity enjoyed by families with young kids.

I left this one where it was, but it was lovely to see.

#365daysofbiking Radio activity and G force

June 20th – Another dusk departure from work gave me chance to take some pictures of networking equipment causing some bizarre consternation locally at the moment.

A handful of local residents have spent some time in the dafter enclaves of social media and decided these white boxes and antenna on lamp columns, traffic signals and street furniture in Walsall are the rollout equipment for the fifth-generation telecoms network.

For some reason conspiracy theorists are given to believe the fifth generation network will be harmful to health, is a plot to test radiation on the population and an effort to spy on us all. Oh, and it’s somehow all connected with low energy LED street lighting.

Well, these boxes and aerials are far more mundane: They are actually pretty much high speed WiFi like we have in our homes, but designed as a specific, peer to peer network for traffic signals and other on-street infrastructure that benefits from central control.

It’s called Mesh4G and you can see it here.

As signals, junctions, crossings, air monitoring and traffic cameras are updated across Walsall, more of these relay units will appear, allowing traffic folk to monitor, modify and control their equipment without having to leave the office.

Which is interesting to me as a geek, but far more mundane than conspiracies would have us believe.

And I’ll still be waiting ages at the Bull Stake junction in Darlaston…

February 22nd – Passing through Telford on a flying visit in the morning, I noticed that the worksite for the new footbridge was oddly quiet. It seems test bores have been completed and are now being monitored for effects on the nearby built environment – including the railway itself.

Along the rails are mounted at intervals surveying datum targets which will be monitored – either manually, or by use of an automated theodolite – to see it recent operations are causing any movement.

A fascinating use of technology.

March 18th – I popped up to a wind-blasted Chasewater, which is still a mud-bath. I noted that the wakeboard lines are reopening for the season, and the canal valve is still open – but by no means fully; the spillway is now dry and the balancing culvert valve has been closed.

The canal filling could well be to do with works ongoing around the Midlands network right now; on recent rides I noticed a lot of drained locks and other works ready for the new season.

Either way, the level seems to have been roughly stable now for a month or so. I presume the earlier dam works have now finished.

It’ll be interesting to see how low the water gets over the coming summer.

March 8th – There’s clearly a traffic survey going on along the feeder routes on Walsall Ring Road. A huge amount of monitoring equipment has been temporarily installed at junctions and crossings, some of it quite high tech.

In a journey between Lichfield Road and Ida Road I must have seen 20 different items of equipment – cameras, motion sensors etc.

This must be costing a lot of money. Wonder what’s going on?

December 7th – it was a beautiful afternoon with a very unpleasant wind, but the sun and commons of Brownhills were a joy to behold. The heaths and scrub glowed beautifully, as did the canal embankments.

These days it’s hard to imagine these beautiful places have a harsh, lingering industrial legacy.

Looking for deer near the site of the lost Coombe House, at Coppice Side, I spotted this monitoring well, a int of a none-too-pleasant past; this is the edge of a former landfill and boreholes like this are regularly unlocked and ‘dipped’ to monitor contamination. The EX symbol warns of an explosive gas hazard – methane, mostly, from rotting refuse buried underground.

This is a problematic site and will require monitoring for many years to come. 

I looked up from it to see the backside of a young hind disappearing into the the copse…

October 22nd – I noted on my way to work the other day that ownership of the former Shire Oak Quarry – now a landfill for dry construction waste – has passed from Tarmac to JPE. I’m not sure why Tarmac sold it, but it was mothballed for a while after the slump in construction after 2008, to be reopened a couple of years later. 

I also noted that dust monitoring equipment has been installed, too. Wonder if that’s in response to local issues or a general requirement these days?

August 8th – I’m intrigued by one of the less publicised additions to the skyline of Brownhills brought about by the refurbishment of Humphries House, Brownhills’ tallest building. I noted some time ago the addition of what I thought were winches for access cradles, mounted on the roof above the major vertexes of the block. It turns out that they aren’t winches or hoists at all, but Domehawk CCTV cameras. I owner who monitors them, how far their field of view reaches and under whose auspices they’re installed?
