“The four large interconnected ponds include typical wetland flora that is native to the UK. Naturally, these plants attract insects like bees and other pollinators, but they also attract mammals, too. Chemicals like phosphates and ammonia come from urbanisation, domestic products like detergents, as well as from human and animal waste. In the future, we need to find more natural ways to treat them rather than adding more chemicals in our treatment processes or building carbon hungry infrastructure, which is unsustainable, and would have an impact on customer bills too. So the wetland is a great solution."
