- 39. Normal Operation Flow fromthe NLL is lifted by pumps at Station F to enable gravity flow to join the NOS and flow to Beckton for treatment. At the moment, if the restriction of flow to the NOS requires alternative discharge from Abbey Mills, then the river penstocks will open and the flow diverts to the Channelsea river. Once the Lee tunnel is operating, those river penstocks will permanently close and the TTT penstocks will divert flow via the Lee tunnel. When the TTT is operating and joined to the Lee tunnel to form the LTT discharge to the Channelsea River will be possible during storm conditions (or at high levels, -3mAOD) Abbey Mills
- 40. Ideally flow travelsdown the nos, enters Beckton inlet works, gets treated and the effluent is discharged to river The nos flow might be combined with flow from Abbey Mills, and Meanwhile to protect the nos there might also be flow diverting to TTT If Beckton starts to reach capacity (there is an F5 at the inlet wks) flow can be diverted to the storm tanks and if necessary discharged to River (untreated). If LTT levels at Beckton reach a certain point,, it can discharge to River via the Tideway CSO (weir). If Beckton has the capacity, the Tideway PS lifts the TTT flow to the nos for treatment. When the TTT is built, there will be discharge point lower than the Tideway CSO (weir), so this will no longer be used to discharge in storm conditions. Instead the Tideway PS flow will be controlled by penstocks so that it Beckton

Honey pots were created and within 18 hours attacks started. Over 28 days 39 attacks from 14 countries were recorded of which 17 would have been catastrophic.
