9:30 am
the tech told me about sugars paralyze between your societies, computers and governments that go crazy. so your data explain how these technologies work. so that's how they can also watch it. now the germany is facing shortages of a precious commodity. climate change, pollution and growing use are leading to water wells no longer being able to meet the demand. spots with water of drinking quality are getting harder to find really got. so for me to find new water sources, even dosing is making
9:31 am
a comeback. so if it pulls up here and you're, um, water shortages are even taking their toll on the very end, beer production, credit and taking destroyed, which means it could produce a lot more. it's better operating below capacity because we're not getting enough water. the bush don becca brewery, and the various southern germany totally on show originally wanted to expand operations here and produce more beer at the brewery, has no wells of its own. its water supply comes from the town and started bag is facing a water shortage limit was said as to how much water the brewery can use and the utility companies reduce the size of the pipe for incoming water place to begin. so
9:32 am
when you have a pipe like this, it's only a certain amount of water, it can pass through any way, you know, but it's also limited right here to a priest that's quantity of a piece of pipe. as i said, as a regular household, water plant to heat help to produce $200000.00 heck the liters per year, but can only make $50000.00 as few the it is simply not enough water today. what are the currently the limiting factor is the municipal supply? mean if we have more water, we'd be able to hook up 3 more tanks. we already have all the piping, alyssa speed, i saw 300 kilometers per north, minus the village of back time, which is also facing water scarcity. the village of 3000 people has its own small water works, but the wells can no longer yield. and now, especially in the summer, there's also a quality issue. the ground water has become polluted with fertilizers used by farms in the area. and therefore it has to be treated at considerable cost and
9:33 am
mixed with uncontaminated water. local mayor calling because she is under pressure is on good tough. the farming industry says it needs a lot more water. take your a gate specialty crop as we do. and people need to have a secure supply of drinking water. and so you can do things, most of them. those are conflicting interests. in the long term, we won't be able to guarantee a steady supply of improved quality drinking water on our own and form a thing close for a farmer and back time, the water scarcity has already become an existential issue. we shot kind of a converted his parents, small sideline farm for gaining production and expanded it significantly the droughts of recent years. mean his business is now in danger. switching to other crops that need less water isn't an option this optic done. so if there was
9:34 am
a demand for vegetables of august, so domestic production meets just 40 or 50 percent of germany's vegetable consumption. but switching wouldn't be easy for us. this is phillips, it's, we have all of the equipment has gone through and invested in these crux. it's the only thing physically to and i was click calling about has his own wells on his farm. but since the beginning of 2023, due to shortages in the region, the authorities have cut the amount of water he's permitted to extract and have this. although over the last few years, the farmer has needed more water and not less tea and other affected farmers have called for water to be pumped here from the nearby river mind. but such a decision takes time. meanwhile, calling about his doing what he can to cut back on water. here he's using hunger, so caustic types to irrigate his time crumbs to minimize of aspiration and that, but i was talking to people with dreamweaver gauge and you need 20 to 30 percent less florida. so you save water by not losing any of the root of the problem here is climate change which has the farm are deeply concerned. the throw continue
9:35 am
organs. we have long to drive periods and more intense heavy rainfall here as well . now this is, but when the oh i didn't have the impression that it was so dry for so long that i'm going to talk more. the crucial factor is what's called ground water recharge, which is when underground aquifers are replenished by water seeping into the ground . areas mark blue on the map are okay. those mark, yellow, orange and red have to little new ground water the regional agency from mining energy and geology has been tracking the development of ground water recharge in northern germany. the mathematical models they've created indicate that significant ships are coming is gifts geezer areas where we know that between the years, 20712100. that will be more ground water going on right next to these.
9:36 am
their areas with the ground water will be depleted. this will be our that's even the context. let's see what kind of implement oftentimes are shown with someone the one hand that will be the question of whether plants will get enough water on side to. and virtually right next door, someone may have problems with their house because of rising ground water. how we still believe them in my house by one type financing. so according to the german meteor illogical. heavy rainfall events have increased by 25 percent since 1950. but such massive rain falls contribute little to ground water recharge because they flow off into the sea via canals and straighten rivers. as a result, in dry somers, more ground water is consumed then as recharged. this phenomenon is called ground water depletion. taishan diva, if may be heavier than before, unless spread out this month. how can we relate that water and bring it exactly to where it's needed done into putting one months then often ne,
9:37 am
paid us talking to north ryan was failure. the local waterworks are busy upgrading here hydro geologist punk schmidt has worked out the ideal place for a new drinking water. well, the aims to be prepared for the impact of climate change. and this is where the will will be installed to might be a. this helps with we have the main stay here, 1500000 cubic meters. that's over 80 percent of the mountain needed from this one location alone or the the well should be finished and ready for use this year. in con, the drilling companies engineer, representatives from the waterworks and a specialist engineer are inspecting the site recommended by schmidt. no, it's a big responsibility for the hydro geology project. he's had to take many factors into account that i might look for 3 sequences for thursday. availability of the land and then the areas where the ground water bearing layers are particularly fixed, where we can expect many meters of sand and gravel that filter the ground water
9:38 am
meter group of filters on the diesel. and then from the ability of the layers is important so that we can insure the amount required can actually be extracted. many of the boxes does this all prefer that to be able to accomplish? this is what a typical extraction. well, in germany looks like. after a test drill the well shopped is dug out and a water pipe installed with a pump. the ground water flows through filter slots into the shaft and has been pumped up. a lot is withdrawn the ground water level control, which is why there are strict limits set by the authorities. function that services are more in demand than ever. he travels all over germany to track down ideal locations for new wells, and always brings his hydro geological maps of the feature data from all tests rails conducted and known ground water, measuring points on some deals with the help of a wealth of additional data. schmidt then creates computer models of where there is
9:39 am
sufficient ground water and where the ground water recharge rate is healthy. to come to see this bundle as i can test the various locations without the need for on site metrics. the model itself contains all the basic data about the area, like that depths of the aquifer, the ground water level recharge rate, etc. and we build on and i can place a well location at any point in the model. but the biggest, at this point is the results show that this is a really useful instruments or subsequent planning to. so i'm going to talk to guess instrumental for the vital call model. further south and central germany. we're going to invest in hosp has a very different approach to use as a controversial instrument to find an ideal drilling site. hello. hi, i'm looking for mr. ben, so i'm around there. okay. can you give him a hand? he got a call from the drilling company, let's know,
9:40 am
and i'm going to finish the delta sibling here. but we want to drill here and asked me to have a look where a good spot with the ongoing, who devotional is the wellness for you all. can huffman his stone masonry business needs up to $40000.00 leaders of water per day, which cost him $4000.00 euros per year? you can pause, i'm up until now. this water comes from our regular water supply, meaning drinking water bottle. i'd like to avoid that costs and use ground water that runs in a water bearing layer instead of to also preserve our drinking water resources in order for noise or own lifestyle disputed. so that's how the idea of for digging a well came up. yeah. when done, com to i know when to go to the best and off tells us he's never been here before and doesn't know the terrain. his client hopes a drilling site can be found as close as possible to the main company building to avoid the need for long pipes. so this is where the 76 year old down here focuses
9:41 am
his initial survey for 30 years. now, he's been conducting searches for water relying on his experience and on his to trust. the plastic rods you show us is through stuff as you can now use what i've learned over the years to find when nature has created the best drilling result for us. which means where the most water is and what data thinking couldn't the size of all doubled use very different methods for doing that and make a teaser one does get this, the angle broad and with and then the bit of 9000 brought me that being removed the unlimited updates, so it's the combination that gets us our results to the company. that's the orange of let's these done does it gave me this is configured. can't wait to see the results and hope it works. us getting back to northern germany to a water works and the old and book area. climate change isn't the only factor leading to water scarcity here. there are also problems with the ground water quality. the oldenburg is supposed to please a show of us if a bond, the
9:42 am
o. w. v is one of germany's biggest drinking water suppliers. the local water company is set up some 2 and a half 1000, measuring points across the area. it extracts water and regularly takes samples to test the quality. several wells had to be closed in recent years because of high nitrate levels due to the over for it alizay sion of fields, the too much liquid mon, newer from factory farming nitrate can be especially hesitates for babies and children. in germany, the limit is 50 milligrams per liter on this sample shows 3 times the permitted level. meaning this water is not suitable for drinking custody monsoons. but that's a really serious problem because we can't remove the nitrate. so that's here. the ground water with our water works so you can size nitrate is a highly soluble salt from lower under treatment plants. country move its thoughts on we would need to sell a nation facilities which would drive all the cost and honestly who to around
9:43 am
double holding deposit of adults in the government's been aware of the problem for decades. but despite new legislation, it's far from under control. in the red areas, the nitrate concentration is above the permitted 50 milligrams per liter which puts germany in violation of the laws on nitrate. otherwise, the job, what's going on? because on it's a clear case of government failure and can be possible. we've had nitrate guidelines for over 30 years now have to dos on few talk. german who's had plenty of time and opportunities to respond and take action against the nitrate. the problem because when i put all of those opportunities being wasted and i came to court, kings come flies to youngs on the goals. there could be a huge bill in the posts for brussels, and i cut up all being avoided back and pay this hug. and the drilling has begun. morning. good. are we good to go? oh, absolutely. is or set up and ready to start. you then so much not, not the,
9:44 am
the new wellbeing doug here will share the work load of the older ones during the dry somers. in this case, due to the lack of rock under the ground, the excavation work is done with the so called grab bucket. this gradually extracts sand and gravel. what makes the task tricky is that the ground water is being exposed, which means there are a host of regulatory and protective requirements that must be complied with, including for the machines being used. if the ground water were contaminated, it would be disastrous. the dressing room, it's view, we can only use organic oil and bio diesel williams. also you can see the plastic sheeting, we have to put under the drilling machines and we have to be careful with refueling . we're subject to very extensive requirements lies the awkward for has a slight flow, so any oil that drops and would be carried away,
9:45 am
you'd probably need a major clean up operation, including extensive pumping and inspections before it's clean again. so anything falling in there would be an utter disaster. so it doesn't have to come up. after 2 days of drilling, large plastic pipes are lowered into the shaft. the engineer checks whether all the materials ordered have been delivered. so that's for the next one. exactly. up and all the intercept equipment is there to yes, so there go, it's never a routine operation. you come to everyone's a 15 plus it's spots with water of drinking quality are getting harder to find the image. so if you want to expand empty wells, less invasive lease, then you have to locate additional drilling sites on the bicycle and also take precautions for the years to come. young, come on the o. as the wells, a job performance declines,
9:46 am
and you need to find new locations. the 40 almost 20 meters down, the grab bucket hits ground water. so have to drill a little deeper to reach the right quantity, but the hydro geological calculations for the new drinking water. well, we're correct the for punk schmidt. that means this job is done. the hydro geologist is constantly booked on the booming sector has seen major developments since the 3 dry somers from 2018 to 202020 from shop systems probably wouldn't call it a state of shock. but it's a very worrying state of affairs soon succeed because you never would have expected it 5 or 6 or 7 years ago. people would say we have enough water in germany. it's just the quality is that's a problem. well, and now it's become
9:47 am
a quantity problem between quantitative spoke. nobody expected it to be so extreme and happen so quickly in central germany. going to invest in office, still divining for water now and again has run switches. any marks the spot many see dosing as non scientific invest in hoff insisted spend delivering results for generations to suit your old, my move um it pulls up here in your um, on the road just gets pulled down. governments. i can also do it with the 2nd person if need be in a gave you the energy transfers and it works when people think you need to have a special gift, but it's something you can learn and come to us. then he says, the ideal spot is where too awkward for his intersect. the frog is unfold. what comes most of it's about where you have the most, what a dump and an intersection gives me more options. and i'll give you the top layer here is 11 or 12 made is down. and the next one is that 30 or 35 meters,
9:48 am
or even data he's done by project government advisory, determining the depth is difficult to devise. they've got to you, but i've never seen more on the rally. been wrong of individually obviously. no, says no the need for time. okay. got it. okay, right here would actually be perfect. well, coincidence. no, yeah, we got lucky. nice on. yeah. yeah, sure. yeah. i say fine, go ahead. now it's time for the drilling company to get to work and time is money. the. the crucial question for the client right now is, will the team find enough water for the stone masonry firm's needs? or will it have been a costly venture over at the organic farm run by a big shot calling about the situation is becoming increasingly precarious. he has 4 wells on his premises, around a 3rd of his crops, now need irrigating due to the extremely modest rain fall in the spring. he conserves water wherever he can,
9:49 am
by digging furrows in this vegetable field. for example, the soul retains more water then if it were level calling about is annoyed and says it's unfair that the extraction quote is from his own 4 wells. were cut in half the balance from that one. if manning is, we're not requesting more instructors, we just want to keep the status quoted in special closing, and that would be a health. we don't irrigate just the final because we want to use up the more times it is. i think it's the foundation of that business and go blog if it ones are not trusting. and he's not the only one feeling frustrated. a number of farmers have come to voice their concerns with the mayor. they've now joined forces to form an irrigation association with the aim of being assigned more water is going to the point of it for losing money by the day. and there's the problem of our ground water rights expiring. as head of the local water works,
9:50 am
the mayor is expected to find a rapid solution. he's brought in experts from an engineering firm. julia steve corporation, has studied the increasingly dramatic situation that our stuff gets thomas on irrigating them, until now they exclusively use ground. hold on. yeah, but extreme drops in the ground water being observed. so the water management agency had declared the moratorium to okay, so the ground hold to to no longer be extracted in areas where the thresholds have been supposed went off, shredded out. and the ongoing find over distribution, the local authority has to satisfy the interests of residents. farmers and nature to one idea of proposed by the farmers is for them to use water from the river mine around 10 kilometers away, solely for their fields, not for drinking water. after looking at the situation, julia still cuz they, she and her boss recommends 1st connecting the village to
9:51 am
a larger pipeline in the vicinity. to relieve demand on the local water works. couldn't stick that in the future of hassle, come from a remote water supply and the other half from local, well is when it goes to mix together. will have a nitrate level below that limits water here already costs a lot more than the national average. but the village has no choice, but to install the 5 kilometers long pipeline. the cost will probably also have to be passed onto water bills adding to all the other growing price increases. but there will be more water available, helping to diffuse the conflicts over distribution. for now, at least water scarcity is also become an issue in urban areas, such as frankfort, where a growing population requires a growing amount of water. engineer on today is power has to find new operations so that water works. companies and other clients are able to cope with the rising
9:52 am
demand. his idea is to bring in water from a nearby reservoir that collects surface water from roads and surrounding towns to be for frank for its drinking water. basically, this would require high tech solutions in the form of modern membranes that can filter around the dust and dirt to discuss effect this weekend. and there's an added innovation cornerstone as the solution also collects water from germany's increasing heavy rain events and renders that usable a little piece. this is what i knew here is that until now, such potentially polluted water was considered taboo for drinking purposes. move on opera, but in this case, you have a reservoir already in place where you can take water that with the right technology i use it can be dependably treated isn't the most frequently discrete climate change is causing greater demand and sweet dial foot was awesome. one device power also uses maps, weather data, and projected consumption levels in his quest for water as an engineer,
9:53 am
he skeptical of dancing rocks. so how things might switch deep sleep. charlotte, there are charlatan. dowser who says he can find 20 leaders per 2nd at a depth of 50 meters at a specific spot is not trustworthy. good, i have done some dousing myself and i did get a responses contested, but without expert knowledge and the principles of geology. i would never think i could determine a drilling location when in fact the reason i'm popping physically over at the stonemasons, they've now been drilling for 2 hours. going to invest in hop says he isn't a charlatan. and he used his housing rods to determine both the drilling point and the depth of the water to be 30 or 40 meters. the community cut the street diving. the problem for the ration with individual is that they need an explanation for everything or deacons. this, what about the heart of dallas thing is to allow for things that you have no immediate explanation for to particularly, and that was the threshold i crossed. and ultimately that led me to becoming
9:54 am
a dallas off to be sure to confused as you're hearing about it. fig, i basically i work with 2 different roads to see solving under this one is called an angle road one. this recipient doesn't mind you want them to you. i find you long some of the like, slow down, not so fast. it has to transfer to your buddy without from kind of you. yes, these company and now we're seeing activity again. oh yes. the most now stand still . does it? yeah. that's the influence of the race. okay. yeah, i didn't believe it either 30 years ago prizes. yeah, but that's not to prove that there is something since even. yeah, you can keep them a little further apart sometimes and also so it's tension in the muscles that makes them come together to industry and even so decent to something good. and then the weight is over, the team hits water clear drinking water flows out of the bar, whole the drilling company teen take measurements to see whether the after flow is
9:55 am
large enough for a well. the drill operator gives the thumbs up. the ground water is exactly where the dallas are suspected to minutes. that's doesn't. we now have confirmation just like mr. preston house said before the water is 30 to 35 meters below ground bodies . each made the under quantity is sufficient for the stone masonry firm environments. between one have a great set to relief and there is a movie that once again, that's true. yeah. so i'm really happy to go to investing hop finished another job successfully, but he's worried in the 3 decades he's been at dallas, or he's seen the ground water level changed dramatically. he's had to download the back, then there were adverbs, dead. so study made, it was also on and now we're talking 60 your id made is what does it and it's not getting any better despite the rain a see how they get on via email. but as there's still too much being extracted in
9:56 am
relation to the fresh rain coming in, but you can define comp, it does. it's an age old problem and the groundwater level of what we're cover any time soon as it's no less drastic action is taken to save water existing via and fema investors pumped back up in north west germany and lower sacks. any, the local water works company, the o w v is gearing up for the future by modernizing some of its wells. in addition to increasing consumption by industry and the growing population, the area has the further problem of toxic pollutants from farming. this new, well, we'll be deeper in order to get a few years reprise the, for the nitrate from fertilizers and factory farming seats that far down into the urine. but in some areas we're already finding ground water, nitrates contamination of deeper levels to invest. so we resort to greater depths with each new well and group if it's possible to drill $1020.00 or 30 meters deeper, then we'll use that opportunity to invite nitrate to contamination nearer to the surface on the old,
9:57 am
off at the office. and on the top that off to all the drilling diversity and there's not a long term solution that is kind of we noticed all of this on civil divorced projections anticipate more extreme weather conditions, more heavy rain and more heat in the summer. we have also for going off the water suppliers, light goes, are facing the big increase in demand tom and especially an extremely hot stores for 5. so conflicts over the use of distribution of water as a resource will definitely intensify bands, expensive cars for sales and down in the bay area. the fight over distribution is already impacting germany's favorite beverage. solely on show is getting less municipal water for his brewery than he'd like in place of more steel tanks full of beer. he's had to set up these water tanks as a stop gap solution. so told me that instead of the 6 days would be able to produce, it would be forced to reduce to 3 days max. so when i've shipped operation here, the water shortage translates into a beer shortage. and the brewery is not allowed to drill its own wells. in the area
9:58 am
so most of us die is just the water that is available is subject to severe restrictions in order to guarantee the general supply type. in germany, water scarcity is an ever growing problem and more areas will be affected in the future. the quest for new water sources has become a race against time. the the
