Water management (SDG 6)

La Tiretaine is a river in Clermont-Ferrand which, in the past, was harnessed to run underground in order to address hygiene concerns and create more land for construction and industrial purposes (Ref. 5). Rehabilitation efforts have been made throughout the city in order to 'renature' the river. Efforts include the creation of a small park along the river near the school Saint-Alyre in 2008 (Ref. 1) as well as a vision to develop a park surrounding a section of the river by 2026 (Ref. 4).

The project was born with the idea of solving the huge debate around the creation of a city park that connects different parts of the city. The area close to the railway will be regenerated thanks to an above-ground park. This solution will allow to have a new green space in the city, and an additional panoramic view that will be experienced thanks to a new cycling path. In this way the whole area that surrounds the rails of the central station will be regenerated, providing at the same time an attempt to mend the urban and social fabric. (Ref.1.)

“The Hub, a new purpose-built student building (at the heart of the Coventry University campus) was designed to enhance the student experience, i.e. offers space to meet up with friends or study informally.” The building also includes a number of green credentials such as: ground source cooling from a borehole on-site; natural ventilation; grey water harvesting (rain water for the toilets); solar water heating and a green roof.” (Ref. 1)

Isar River had been regulated at the end of the 19th century by forcing the river into a canal-type bed with embankments. This regulation made a negative impact on the flow velocity of the river, on its temperature balance, and increased the risk of flooding. The goal of the recent development was to restore the river's natural character on an 8-kilometre-long section of the river and to create a semi-natural riverside. (Reference 1, 2) This was considered especially important because the effects of climate change have already increased the frequency of heavy rain events and major floods. (Reference 3) The new concept leaves space for the river to shape and change its bed with every flood. Further aims of the project were to increase biodiversity and recreational quality.

Hailes Quarry Park (HQP) is a large open space in the south-west of Edinburgh. It covers an area of 12.15ha. HQP was a very boggy area in the centre of the park which was effectively out of use. A project was planned which aimed to make environmental improvements and engage the local community and encourage healthy living. One of the main features of the park’s recent development is the creation of a wetland area with a range of wetland plant species. This new habitat will be home to birds, amphibians and native wetland plants, and will be a part of the green corridor. Additionally, a Biodiversity enhancement project was carried out at the site (ref 1, 7).

“The Living Environment Trust is an environmental charity based in Coventry, which aims to promote environmental and sustainability awareness within local communities. Accordingly, the Trust uses the restoration of neglected inner-city green spaces as a way to engage a range of community groups, whilst also serving to enhance and expand the existing biodiversity and develop important community and educational resources.” (Ref. 1) “The Living Environment Trust was formed in 2007 to transform the neglected land around the Alan Higgs Centre into a community ecological and leisure resource.” (Ref. 2)

In 2016 the Municipality of Lisbon started the renovation of the Botanical Garden of Lisbon, declared in 2010 as a national heritage monument. The botanical garden is both a vital urban open space and a significant cultural landscape of the city. This Botanical Garden is home to an important collection of plants with economic value, reflecting the strong links to the Portuguese expansion and the routes of the navigators that spread them across the various continents. The intervention is expected to provide improvements in the irrigation and water circulation systems, in the rainwater harvesting system, in the reorganization and improvement of garden green spaces, and in the restoration of paths. With the objective of requalifying the space, bringing significant improvements in terms of sustainability of resources, visitors safety, new cultural and recreational opportunity spaces (Ref. 3, 4, 8).

This area of Keighley is drained by a combined sewer system operated by Yorkshire Water. The natural drainage system is poorly defined.
During extreme rainfall, water from the park and adjacent housing flows down the hill and into the surrounding area and causes flooding. Storage in the form of SuDS was provided in Devonshire Park using a series of “trench trough” structures. These take the form of depressions (swales) with gently sloping sides (ref. 1). Extensive flooding in 2008 and 2012, the local resilience group has been working tirelessly to reduce flooding in Devonshire Park areas (ref 4). Up to £170m of this has been brought forward to accelerate work on ‘shovel-ready’ flood defence schemes to begin construction in 2020 or 2021. The Keighley and Ilkley constituency are one of the beneficiaries, with improvements set to be made to Natural Flood Management aspect of the Leeds Flood Alleviation Scheme, providing an immediate boost to jobs supporting the local economy (ref 4).

Due to the frequent episodes of flooding, the city of Bari has started thinking about becoming a laboratory where experimenting a new landscape approach, with the additional benefit of enhancing daily liveability. New green spaces have been built within housing areas (apartments that the municipality provides for those who have low income). (Ref.1&2) The aim of Garden Faber was to create a community garden, designed and made by residents for residents (Ref.1.) As of July 2020, no sources were available to understand if the community continued with the garden.

A five-year project, would be the largest sustainable water drainage system project to be implemented in Glasgow. The investment follows years of study by the Metropolitan Glasgow Strategic Drainage Partnership, which includes Scottish Water, the Scottish Environment Protection Agency and Glasgow City Council.
