Reconstruction of Lepiku water course

Actor: Tallinn City   ●   Year: 2015   ●   Address: Tallinn Botanic Garden, Kloostrimetsa tee, Tallinna, Viro

A reconstruction of the Lepiku water course in the Tallinn Botanic Garden was realized in order to improve the quality of rain and melting water and protect the Pirita river.

Description

Lepiku water course runs through Tallinn Botanic Garden, collecting rain and melting water from the surrounding area before entering the Pirita river, which is a Natura 2000 site. Recent residential development in the Lepiku area has increased the amount of water entering the Lepiku water course. This development has had a negative impact on water quality. Furthermore, the original limestone walls in the water course had collapsed and the riverbed and culverts were stocked with sediments. Especially the solids in the water were of concern, because they contain nutrients, heavy metals and other harmful substances.

Benefits

The reconstruction aimed at a natural purification process which aims to decrease the amount of particles in the water. Meandering of the creek, shallow thresholds on the bottom of the course and extended flooding areas were used to retain water flow and increase sediment settlement. Furthermore, solids are filtered from the water by the wetland vegetation on the sides and the bottom of the course. To prevent erosion, the walls of the water course are lined with limestone.

Background information

The reconstruction was realised in EU Life+ programme co-financed project CITYWATER.
