About half of the building plots will be sold as free sector plots. Participation by the buyers of these plots will be voluntary.

Hydraloop offers a full product range of stand-alone and concealed water recycling devices for residential and commercial real estate. Hydraloop purifies the water from showers, baths, and washing machines as well as condensation water from tumble dryers, heat pumps and air conditioning units. Hydraloop water can be re-used for toilet flushing, washing machines, garden irrigation, and topping up swimming pools. Hydraloop's patented technology is consumer friendly, carefree, and sustainable. Our treatment process removes dirt, soap, and other pollution from greywater without the use of filters, membranes, or chemicals.
