More and more cultivator are looking at their water supply . Good water supply can no longer be pick out for grant . " The same apply to water as to CO2 . That is really underestimated . Sometimes people still recall about it too casually , " notes Ben Hoogendoorn of Horticoop Technical Services . Although he can see from the interest in underground water warehousing , among other things , matter are changing . " For sure areas , it is an interesting choice . "
With underground pee storage , water is infiltrate into underground aquifers with the aim of being able-bodied to use it during dry periods . Even in the notorious soaked Netherlands , those ironical periods are becoming more frequent . Many a grower will be conversant with the prototype of a slow emptying pee river basin while industrial plant need water day by day .
Reverse osmosisGrowers have been making right use of rainwater for old age . They pull in it , in basins or silos , sometimes with reverse osmosis as an intermediate step to bring the piss to the desired quality . Reverse osmosis is also an intermediate footprint used to make water from other source suitable for function as irrigation H2O .
The only question is , how long will reverse osmosis be allowed ? Ben also quotes . " Reverse osmosis remains a talking point . You have been take heed for years that it is coming to an end , but it is still not banned . It is a hoar area , though . " However , as long as there is no choice , it should not be banned as far as the Horticoop Technical Services sales manager is concerned .
Meanwhile , a grower can use undercover water supply storage just okay , and , according to him , it is now the only choice to osmosis . With the water challenges at hand , the engineering company sees opportunities for underground H2O depot . " Like reverse osmosis , you use standing bubble underground . you may put urine in there in the winter if enough pelting fall . In summertime , you may take that water out again . " If the wells are far enough apart , agriculturalist can combine reverse osmosis and undercover water storage .
ECYou ca n’t stash away weewee in standing underground bubble everywhere . " In Tinte , we did some piece of work , but there the EC turned out to be too high . The dirt was too piquant . Of every 10 liters of good water you interject into the soil , you only got back one good one . The water salts very quickly , so it is not profitable . "
The type of grease also matters . With flaxen soil , even the layman understands that water system does not ' sting ' well in the stain . In Limburg and parts of North Brabant , secret water storage is therefore not really an alternative . Around Steenbergen and Dinteloord , on the other hand , it does happen , and in other regions , it goes well .
These are regions with serious standing water layers with also grim EC , in which surreptitious water storage is good . The same apply to the region around Aalsmeer . " There you get 7 or 8 litre out , for example , for every 10 liters you put in . Then it becomes interesting . "
They are also working on projects in Westland , Ben knows . He points out that a higher EC in the soil does not have to be an immediate trouble . " Do you dare to grow with a slightly higher EC , is then the question . If the bubble you store piss in is not with child enough , you get blend , and the EC can surface . Then it ’s a matter of watching carefully when you need to infiltrate water and take it out again . "
SourcesTo get well wells in the soil , H. G. Wells have to be drill . Horticoop Technical Services does not do that itself . " A medical specialist in drilling fountainhead represent what the soil bet like and , for model , also look at where other well are in the soil . This can be done at different depth , say 30 , 50 , or 100 metre . That is determine in the field . "
Based on how much water a agriculturist want to store in the soil , the bit of H. G. Wells is determined . Sources should not be too near together . " It variegate here how many cubic meters of H2O a client want to penetrate and extract . play with different heights and thus storing water in different layer is possible , " Ben knows .
Horticoop Technical Services itself has a lot of expertness in hush-hush water storage . With the accomplishment last year , of hoi polloi from Codema with specific cognition , even more expertise was summate . " We have the materials , the knowledge and can also engineer everything , " he enounce .
clean-living and nerveless waterAbove ground , a grower typically needs about 10 square meters of distance to instal underground water storage . A grower needs a filter system of rules and a pumping social unit . " The filter system of rules is ask to filter the basin piss before you penetrate it . The pump is needed to fetch it back up later . By pump in fresh water , the well stays well unobjectionable , and you also get uncontaminating water back . "
integrating into an exist pee organisation is gentle . " After pumping the water up , it can go back into the washbowl after filtration , for exemplar . After that , the cultivator can disinfect the urine if necessary , as is done with water supply from other source . Due to the frequent filtering , the water system from clandestine water storage is also staring for use in drip and mist systems . "
Other advantages of undercover water storage are , of course , that it allows growers to make smart usance of the available space because , unlike a basinful when build , ( scarcely any ) supernumerary soil is needed above ground and that the water stays coolheaded well and free of algae .
" Above land , it is often difficult for growers to find any more space , but customer - specific , we always get hold a free turning point for the piece of above - ground installation , " Ben know from experience . " Once the wells are drilled , things can move quickly on site . Usually , the building block can be finished in about a calendar week . planning is still the most piece of work . It is best when a grower can begin stash away water flop at the start of the rainy time of year . Those who pop out now are still in unspoiled time . "
