Really depends on how much higher the treatment plant is against the expected upper level of the burn. A down stream bend wouldn’t hurt 

Thanks, I have a look to see exactly. I'm slightly concerned that if the river keeps the flap valve closed for any length of time that the plant will back up anyway.

Exactly! If you have a descent head from the plant then it would be enough to open the flap but you also wouldn’t need the flap.
