An ad for a recent interview we did. https://www.youtube.com/watch?v=ybU7hLdz9OU Unfortunately due to copyright it's probably only viewable in Australia, however I just thought I'd chuck it on here in case any of you visit Australia in the future or that you may know a way around it (or for any Aussies that are on OS. I've done over 100 media interviews regarding the Cave Clan & this one is unique. It focuses on a few of the artists in the Cave Clan (and me ) It's not the real Cave Clan, it's the grey haired, wrinkly & flabby Cave Clan. Please feel free to share. http://iview.abc.net.au/collection/cave-clan http://i20.photobucket.com/albums/b248/DougCaveClan/Mobile%20Uploads/IMG_20170116_104132_636_zpsa76mbnu0.jpg
History â€œThe area used to flood quite regularly until the corporation carried out work to improve the drainage system. The water used to come up through the drains after heavy rainfall as there was nowhere else for it to goâ€. Markeaton Brook, which runs through the centre of Derby, has been the cause of many problems since the medieval ages. As early as 1610 it is recorded that the brook spilled over its banks, flooding a nearby gaol which killed three prisoners because the cells were located beneath street level. Floods continued to torment those living in Derby throughout the years, and St. Werburghâ€™s church is rumoured to have faced extensive damage in both the 18th and 19th centuries. A Great Flood of 1740 was perhaps the worst of all, however, since it caused great damage to many homes, as many rooms which were positioned on the ground floor were entirely submerged. A significant amount of cattle was also swept away from nearby pastures during this disaster. More recently, in the early 1930s, Derby endured two more major floods which remain famous to this day since they each caused some substantial damage and disruption to the centre of the town. The first occurred in September, 1931, after many days of heavy rain. The full effect of the flooding led to many residents who lived alongside the Markeaton Brook being trapped inside their homes. Many shops were also damaged. Additionally, several allotments were ruined and what would have been the harvest was uprooted and swept through the main streets. The second flood hit the area in May, 1932; this was also known as the Great Flood of Derby. The damage to buildings throughout Derby was catastrophic. Alongside the effects of Markeaton Brook, it is thought that excessive rains from the hills around Kedleston and Mickleover also caused what was described as â€œan avalanche of waterâ€ to cascade throughout the town since it is located at the base of the neighbouring high ground. While a large culvert did exist, and had done for ninety years or so, the sheer volume of water was too great. By ten oâ€™clock on May 22nd water had already breached the streets in low lying parts of Derby, to the extent that shops in the Cornmarket, St. Jamesâ€™s Street and St. Peterâ€™s street were submerged half-way up to the windows. Describing the scene, one resident suggested that â€œthe centre of town presented the appearance of a lake and the sight was unforgettableâ€. In the aftermath of the 1932 Great flood, the Borough council launched an investigation to understand why the area was hit so badly. In response to the research that was carried out, two flood relief culverts were constructed. Further improvements were also implemented on Derbyâ€™s sewage system. The relief tunnels were officially opened in 1938, with the first draining excess flows from the Markeaton Brook and the second taking surplus water from Bramble Brook. Each brook has its own inlet spillway along with a weir that overflows during periods of high flows, and once inside the system the flows are taken eastwards for 2.2km, beneath the suburbs of Derby, to an outfall in Darley Park which links to the River Derwent. It is estimated, especially during the winter months, that the catchment can generate a flow of 50 cubic metres per second within thirteen hours of heavy rainfall. Since they were originally constructed, the culvert has been improved and upgraded to cope with expected deteriorated that has occurred over the years. Our Version of Events With the alarm set at 5.30am, we decided that we would aim to get an early night after a BBQ which was organised by KM_Punk. But, once the whisky came out, it was clear that the original plan wasnâ€™t going to happen. After many burgers, sausages, a couple of cheese slices and a philosophical conversation, we made it to bed around 3.30am; those of us who didnâ€™t pass out at least. Two hours later, with blurry vision and the taste of whisky still in our mouths, we rose â€“ albeit very slowly â€“ at 5.30. After a quick coffee though, we managed to grab our cameras and tripods, and a bucket for The Shepshed Diamondback, before we made our way to the car. Somehow we managed to endure the early morning â€˜domesticâ€™ which exploded in the back by cranking up the volume of some good old heavy metal tunes, and, as it turned out, the bucket wasnâ€™t needed after all; so we could say that, in spite of the late night shenanigans which ended only a few hours earlier, the plan was coming together quite well. We arrived at our destination in good time and it wasnâ€™t long before we were climbing our way into Markeaton Interceptor. Due respect to The Shepshed Diamondback who managed to get this far whilst in such a state, but he wasnâ€™t quite so lucky once inside the overflow culvert. Despite his tentative steps, the slimy slope claimed its first victim and he went down harder than a sack of potatoes while yelling something about saving his camera. Ultimately, all I heard was a very loud BOOM echo throughout the tunnel. The slippery tunnel would later claim more victims, but somewhat ironically, only those who were stone sober! (The Stranton Express for instance who, all of a sudden, sounded like a derailed train). On the whole, however, despite the slick surface in certain areas, the Markeaton Interceptor is a fantastic example of late Victorian architecture and the overflow culvert stands, rather proudly, as an example of something that was built to last. It is only while you are stood inside the tunnel that you can really comprehend the sheer size of the place, and the effort that must have gone into building such a structure. Explored with KM_Punk, ACID-REFLUX, The (Still Pissed) Shepshed Diamondback, Miss Mayhem and Stranton. The 1932 Flood. 1: 2: 3: 4: 5: 6: 7: 8: 9: 10: 11: 12: 13:
The original draining guide everyone reads was written for the Australian drainage systems and didnâ€™t cover many of the issues found in draining in the UK. If you are thinking of heading into your first drain I would personally recommend starting with a culvert where you normally wouldnâ€™t find methane or H2S gasses. You should also consider if you have claustrophobia or arachnophobia, some people donâ€™t think of this first but when your thigh deep in water with spiders the size of a childâ€™s fist above you it really isnâ€™t the best time to discover you donâ€™t like being in a wet, dark, enclosed space with massive spiders. On the note of spiders, most UK spiders are not poisonous but the Faux Widow and a couple of others can give quite a nasty bite, these spiders are normally found in the south/ south west of England. http://www.nhm.ac.uk/nature-online/life ... der-bites/ 1. Culverts/Underground Watercourses. A culvert is a drain or pipe that allows water to flow under a road, trainline, town, or similar obstruction. It is not uncommon for Combined Sewers (see below) in close proximity to a culvert to have an overflow within the culvert, conveniently out of the gaze of the general public. Combined Sewer Overflows (CSO) allow an amount of flow from the sewer to discharge into the culverted watercourse during times of excessive rainfall, usually via a screened overflow set-up, to avoid the sewer becoming surcharged. The dangers in culverts are varied but include; trip hazards from debris washed in, tidal flooding, flash flooding, bad air and build-up of gasses from attached sewer outfalls. Culverts are safer than sewer or CSO systems. 2. Storm Drains. Storm drains by their very nature are designed to handle a large amount of water in a hurry. Most of the time storm drains will have little water but have a large catchment area and can fill quickly. The most common UK storm drains that get visited are; Bunker â€“ Warrington Dreadnaught â€“ Bristol Flo-Selecta â€“ Derby Storm drains can have CSO systems attached as well as storm water holding tanks. The dangers of culverts are still present in storm drains but the risk of flooding is far greater. Always check the weather before heading into a storm drain and in the case of the system out falling onto a major river also check the local tide times. 3. Sewers and CSO systems. A sanitary sewer (also called a foul sewer) is a separate underground carriage system specifically for transporting sewage from houses and commercial buildings to treatment or disposal. Sanitary sewers serving industrial areas also carry industrial waste water. A combined sewer is a type of sewer system that collects sanitary sewage and storm water runoff in a single pipe system. Combined sewers can cause serious water pollution problems due to combined sewer overflows, which are caused by large variations in flow between dry and wet weather. This type of sewer design is no longer used in building new communities, but many older cities continue to operate combined sewers. Sewer systems are the most dangerous drainage systems to explore with risks such as potentially explosive methane gas, bacterial infection, sudden flooding from rain or a penstock opening further upstream releasing a large flow of what can barely be called water and the big one hydrogen sulphide H2S is a colourless, odorless gas that at higher concentration is more dangerous than cyanide http://en.wikipedia.org/wiki/Hydrogen_sulfide Another issue is Weil's disease which is passed along in infected water from animal urine, after 3 days or so you suffer severe headaches, red eyes, muscle pains, fatigue, nausea, fever and in some cases a rash and hallucinations. If its really bad dose symptoms include hemorrhaging from the mouth, eyes and internally. There is significant and rapid organ damage: liver and kidney failure can occur within 10 days, leading to jaundice (these are the only cases that can properly be called Weil's disease). Hospitalization, followed by antibiotics and often dialysis, will be required if the patient is to survive. Recovery can take months. Drain exploration can be a very rewarding and here in the UK we donâ€™t have many of the risks found abroad such as animals that will kill you with a bite or intense sudden downpours of rain resulting in flash flooding. Once you understand the risks and use a little common sense youâ€™ll be wading around underground in no time.
