A biological filter for the Parco dell'Acqua lake

Type:
Ornamental pond
Zone:
Municipality of Brescia
Year:
2015

The Parco dell’Acqua is a park in Brescia. It is home to a lake spanning approximately 1,000 m² that was fitted with a mechanical filtering system designed for swimming pools. It was incapable of keeping the water quality sufficiently high without the use of chlorine, which would have killed the fish and water lilies in the lake.

We were asked to provide the lake with a filtering system to work in tandem with the existing one and guarantee exceptionally high water quality. It needed to feature biological filtering that would not harm the wildlife in the water in any way, while also enhancing the vegetation in the lake from a botanical point of view, thus increasing its appeal in the eyes of visitors.

Following a year of observation, instrumental monitoring and analysis of the properties of the water, we decided to give the lake a large biological filter featuring purifying plants that will ensure that the water quality remains consistently high and keep it alive, with no need to use chemical products.

In an area of the lake, we built a plant-based purification section containing a selection of native species from the local area, which we picked in partnership with the park’s biologist.

The appearance of the lake in the park has been radically changed thanks to the lush greenery that serves as a filter. As well as looking stunning, it guarantees outstanding water quality without using chemical products.

The colours and shapes of the aquatic and wetland plants in the changing seasons add a special touch to the lake and provide shelter for the newts, frogs, toads and small birds that live in and around it.

Another hugely important objective was achieved thanks to the cutting-edge pumps that were fitted, which have extremely low power consumption and have thus brought about a considerable reduction in electrical running costs.
