The landscaping project direct attention to an aesthetic role, and to a functional in terms of the carefully selected native flora and fauna, in order to achieve a self-sustaining ecosystem. Therefore, the plans include the planting of coastal and aquatic plants.
The lake can be divided into two basic zones. The first is the deep end while the other includes the self-sustaining ecosystem with lush aquatic and coastal plants. The planting of plant material is carried out in baskets and/or geotextile bags, with the application of a special substrate for planting plants in lakes (a substrate containing low proportion of soluble elements for reducing the amount of inorganic elements).
Lake construction involves digging using wide trench techniques, where granulated gravel is disperses as a blanket course, and a water impermeable EPDM folio is placed at the bottom. The shoreline and bottom of the lake are covered with an impermeable geomembrane (1.1. mm EPDM folio) which regulates the water level.
The quality of water in the lake is self-regulated using a natural purification process and aided by a honeycomb filter in which impurities are trapped and a bio-decomposition process is achieved using bio-filters.
The use of chemicals in this kind of system is not permitted, i.e. the water quality is regulated exclusively through aeration and filtration. Honeycomb filters (BIO-FILTERS) ensure a natural decomposition process of organic elements. The quantity of honeycomb filters depends on the size of the water section. The result of using this kind of system is crystal clear, purified ‘living water’ without the use of any chemicals.
The lake has several sections, a deeper and shallower section (skimmer section – zone of more intensive purification using bio-filters) and zones where water purification is performed exclusively using the planted native aquatic plants. Honeycomb filters are positioned in the lake, in the skimmer section of the lake and the shoreline on the gravel embankment.
The pumps are positioned in the actual lake, and for this reason, there is no need to install devices directly near the lake (as is the case for lakes that use chemical substances).
The use of honeycomb filters along with minimal maintenance ensures a high visual and hygienic quality of water.
