Lots of news in the watery world over the last 2 weeks, so here’s a round-up on water resources, surface water flooding, water company fines, chalkstreams and others. Bear with me, there’s a lot to cover; some good, some bad! 🧵 
💧 Water companies (& in England, Regional Water Resources Groups) are consulting on plans to mange water supplies. It’s key that they hear what customers want, including as @RichardsonNath stresses, the need to stop investigating and START DOING.
💧 @NatInfraCom published its report on reducing surface water flooding. By 2055, 600K properties could be at risk. Recommendations include that Govt. implements Sch3 of the Flood & Water Mangt. Act 2010, setting mandatory standards for sustainable drainage in new developments.
The mid-Wales line is flooded - again! If @tfwrail struck agreements with farmers high in the catchment to invest in #NaturalFloodManagement, they could prevent it, at a fraction of the cost.
But all the flood control is at the bottom of the catchment - a recipe for failure.

When the hills are bare, the rivers straightened and largely treeless, water rushes down to the lowlands unimpeded, causing flood peaks that drown the railway line. Hard engineering at the bottom of the catchment is overwhelmed.
Look at the whole system, not just the floodplains

The trick is to hold back the rainwater in the hills for as long as possible, de-synching the tributaries and attenuating the flood peaks. It has been shown to work again and again. But the hard-engineering mindset prevails.
