Interesting Solutions for Poorly Draining Sites.

Without wishing to sound like a broken record! Our site has been struggling to cope with the recent downpours. Due to continued urbanisation of many green areas, finding innovative solutions to drainage is becoming a hot topic of discussion.

One solution is to turn a negative into a positive by creative channeling of rainwater. We have all no doubt heard of the benefits of collecting rainwater via guttering and water butts, but what about the play opportunities associated with rainwater?

One of the leading voices in innovative play landscapes is Norweigan playground designer Frode Svane. His vision for rainwater play has been incorporated into a guide produced by Planet Earth Ltd. for London Play in association with Natural England.

Below are a few extracts from the guide:

'New requirements to install sustainable drainage systems have been introduced following recent catastrophic flooding events in lower river valleys. We [London Play] want rainfall to stay in the local area and sink into the ground, not be whisked away to flood somewhere downstream, but we also want to make rainfall fun for children to play with.

The guidance has been produced with funding assistance from Natural England, and written by Planet Earth Landscape Architects, with advice from Bob Bray Associates and photos from both of them and from Norwegian playground designer Frode Svane.'

Case Studies


Fort Royal School, Worcester




This is a special school with many different needs. Runoff from the upper car park 
is cleaned through a permeable pavement and released through a rain chain. 
Open rills carry water through a small courtyard and sett channels take water to 
the school green space. A formal pond with a glass window allows pupils to look 
into the pond safely. A habitat pond will allow pond dipping and act as a home for 
wildlife with balance beams over water and access to moving water provide 
further understanding of what happens when it rains.



Planet Earth Ltd, St Mary’s Frobisher Park, Peckham, London

 


Planet Earth have been transforming this declining pocket park into a playful,

magical semi- wooded landscape. Lush woodland planting surrounds a colourful

river channel. The river source starts at the ‘rocky mountain area’ a high point at

the back of the site and flows down along the natural levels into a reedbed in the

river ‘delta’ area. In heavy rainfall children will be able to enjoy chasing rainwater

running along the river channel and through the site. The reedbed has been given

an extra safety precaution to satisfy the local council’s peace of mind using steel

mesh hidden beneath the reeds that is bolted to the surrounding concrete.


Planet Earth Ltd, Argyle School, Camden, London

At Argyle School, Planet Earth designed a ceramic surface water-system that
collected rain water from roofs. Using a hand pump, the children could pump
water into the channels and watch it collect in their very own pond with frogs and
water plants.
