We can make a significant contribution towards saving our water resources and also create ecologically and economically viable routines by using rainwater and implementing mini-wastewater treatment plants.

Image: © Igor Yaruta - Fotolia.com Rainwater can be used for a multitude of purposes - from watering lawns, hedges, shrubs and flowers, filling ponds, artificial streams and wells, to cleaning patios, roads, yards and steps around the house. The result: happy plants that thrive on the non-calciferous water, enormous amounts of drinking water are saved and costs are reduced - a worthwhile result from an ecological and economic perspective. Household wastewater with biological value The objective of wastewater treatment is of course to return water to nature in a condition that will not add...

Roth Twinbloc® low-profile storage tank Advantages at a glance The optimised, low-profile design of the Roth Twinbloc® storage tank offers considerable advantages in terms of installation. Compared with traditional rainwater tanks, excavation is reduced by up to 40%. The tank’s ultra-low profile makes it a feasible solution in areas with high groundwater levels. The two parallel cylinders provide additional stability, because two tank chambers with smaller diameters are significantly more stable than a single chamber with a large diameter. This configuration allows unrestricted use of the...
