“Tideway has been a proud supporter and corporate partner of Thames21 since 2015. 
We share a desire to reconnect Londoners to the river and the brilliant community engagement of the Thames River Watch programme has included not just communities but also our own staff. 
There has also been the wider value of fostering a responsible business culture, which has paid rich dividends in terms of staff engagement levels.”
John Sage, Head of Corporate Responsibility, Tideway

Place your business at the heart of nature-based, community-focused solutions by funding a project that delivers specific goals, for example:

Deliver measurable improvements to water quality and biodiversity

Reduce flood risk to commercial and residential properties 

Train citizen scientists to tackle plastic pollution and monitor water quality

Inspire people all across London and the Thames basin to get involved in their local rivers

Support young people on their pathway to ‘green’ jobs


“The responsible management of river environments is vital not just to our business but also to the sustainability of cities, towns and wildlife. 
Through our partnership, we designed and created a 3,000m2 of wetland in Broomfield Park, North London. It stores fresh water and improves water quality, which is hugely important to the water-stressed Thames Basin catchment. 
We’re thrilled with what the partnership has delivered so far.”

Holly Firmin, Senior Community Partnerships Manager at Coca-Cola Europacific Partners (CCEP) GB

Water stewardship is “the use of water that is socially and culturally equitable, environmentally sustainable and economically beneficial, achieved through a stakeholder-inclusive process that includes both site- and catchment-based actions.” – Alliance for Water Stewardship

Thames21 delivers nature-based solutions such as urban wetlands that naturally filter polluted water and return – sometimes known as ‘Replenish’ – a volume of water of improved quality to the local catchment in ways that: 

– Address shared water challenges for local communities and stakeholders
– Have a measurable and positive impact on the availability, quality, and accessibility of water within a catchment
– Align with best practice for corporate water stewardship  

Ideally placed to identify and implement measurable and cost-effective interventions, Thames21 works with companies such as Coca-Cola, Google, and Microsoft to deliver ambitious water stewardship objectives.
