Week 77, Day 4:

• More work on the swale for the rainwater drainage, connecting up the inlet pipework
  • The swale inlet is a precast concrete unit from ACO, specifically designed to slow down the incoming flow and spread it out sideways to avoid eroding the soil to create a single narrow channel – more info at ACO SuDS Swale Inlet
  • This looks a bit odd – especially when it first turns up in a Google search – but it does the job very well and there aren’t many alternative precast units in such a small size (this takes a 160mm pipe but a lot of them are designed for large housing developments with much bigger flow volumes)
