SUMMARY:London Rivers Week 2026: Stanley Picker Gallery's exhibition - A Simultaneous Agreement
DESCRIPTION:All are welcome to the Stanley Picker Gallery’s exhibition ‘A Simultaneous Agreement’ presented as part of London Rivers Week 2026. The exhibition officially runs from 22 April to 18 July 2026. \nThe Stanley Picker Gallery is open Tuesday to Saturday 11am to 5pm (during exhibitions). There’s no need to book a ticket\, just drop in. \nRooted in the Hogsmill River beside the gallery\, the exhibition traces connections between English chalk streams\, Saharan phosphate mines\, and global extraction networks\, foregrounding water as both a life source and contested infrastructure. At its centre is a functioning glass fountain that filters river water inside the gallery\, alongside wearable activated-charcoal sculptures that question the logic and limits of technological purification and circular-economy solutions. \nOperating as both exhibition and civic platform\, the gallery becomes a consultation space and site for live performance\, contributing evidence towards a campaign to designate part of the Hogsmill as bathing water. \nAll under-18s must be accompanied by an adult. Please bring a bottle of water.

SUMMARY:London Rivers Week 2026: Perivale Park Litter Pick
DESCRIPTION:Join Thames21 for a free community litter‑picking session along the River Brent in Perivale Park as part of London Rivers Week 2026! \nThis hands‑on event is a great opportunity to help improve local river habitats\, support wildlife\, and keep one of West London’s much‑loved green spaces clean and welcoming. \nWe’ll provide all equipment\, including litter pickers\, gloves\, and bags. Just bring weather‑appropriate clothing and plenty of enthusiasm. If you can\, bring a spare set of clothes as well. No previous experience is needed. \nAge requirements: \nThis event is 16+. \nWhat to expect: \n🦺A guided safety briefing at the start \n🚮Litter picking along the river corridor and surrounding parkland \n🌿A chance to learn more about river restoration and local biodiversity \n🫂Opportunities to meet like‑minded volunteers and enjoy the outdoors \n🫖 Tea and biscuits will be provided. \nPlease be prepared with comfortable and weather appropriate clothing and shoes\, a packed lunch and plenty of water. \nWhy it matters: \nLitter in and around the River Brent harms wildlife\, degrades water quality\, and affects the experience of the community using the park.
