Clean water is a valu­able asset. More than two-thirds of our 'Blue Planet' is in­deed cov­ered by water, but only 2.5 % is fresh water, which is fast dis­ap­pear­ing. Only 60 % of the world’s pop­u­la­tion is con­stantly sup­plied with fresh drink­ing water. The short­age of water not only af­fects coun­tries in the south­ern hemi­sphere but many other coun­tries too, es­pe­cially dur­ing the sum­mer months. The aware­ness of the value of water has in­creased world­wide. It can be wit­nessed in the es­ca­lat­ing cost of drink­ing water sup­ply and sewage water dis­charge world­wide.  The total de­mand for fresh water has also in­creased and our nat­ural sources will be un­able to com­pen­sate in the long run. It is clear that new sources of water must be de­vel­oped.

In the fa­mous tale from Greek mythol­ogy, the God Po­sei­don wanted to gift some­thing to the peo­ple of At­tica. He thrust his tri­dent into the rock (on which the Acrop­o­lis stands today) and from it gushed a spring of water which was said shall never run dry. But the peo­ple, not hav­ing the vi­sion or re­gard for the huge ben­e­fit that this in­ex­haustible source of­fered, did not like his gift!

Today how­ever, we un­der­stand what it means to have our water sources run dry. It is hap­pen­ing in many coun­tries now and there­fore we are look­ing for durable and sus­tain­able so­lu­tions that meet the spe­cific needs of con­sumers.

Our com­pany vi­sion is to en­able con­sumers to bet­ter use the re­sources of rain­wa­ter and grey water, rather than fresh drink­ing water, in do­mes­tic and com­mer­cial ap­pli­ca­tions, and chan­nel ex­cess rain water back into ground­wa­ter reser­voirs in an ef­fort to in­crease the world’s sup­ply of drink­ing water.
