Those details are about as clear as I have seen. Thank You.It would be helpful if the facts were made clear.Rainwater does not come from Harrow to Brentford.It does come from Horsenden Hill to Brentford .There are a number of subterranean brooks and rivers, mostly ducted coursing through the entire area towards the Thames. Notably the River Brent and the Grand Union Canal but also the Radbourne.The Brent has a flood plain ( which is to be built upon ) and had an additional flood alleviation in Perivale some 35-40 years ago.The Radbourne splits in several places coursing through differing sub-bases and T.W. does not have a very good database of exactly where, apart from the ducted and mapped parts. It flows under Northfields Station ( where it can be heard) and is visible at Lourdes Mount beside Mount Carmel School. Radbourne Road is another indicator and Junction Road has its name as this is where it splits. Brook Lane and Brook Road are others. The Clay Ponds also drained to the river hence the Waterworks and pumping stations location when industry arrived in Brentford.I don't suppose it will come as a surprise to many that despite the clues, consultants and surveyors were ignorant of much of this as it simply had not been digitised.Most of the more recent flood problems come from near 50 years of the complete lack of street by descaling of shared sewers and soakaways and relief drains.Nothing has been done for increased developments since the 1960s and the fact that much of the housing lacked bathrooms . Now, even ensures are the norm as are washing machines and dishwashers et all. The drainage system , in the main remains the same.All the more reason for it to be properly maintained.The suds is not maintenance it is to cope with enabling the mega developments in Ealing and the back ups that occur now from major developments in Brentford.Water infrastructure, like fire safety access is easily brushed over in planning and the problems manifest often years after completion.That does not excuse the hopeless traffic management that has stuffed up links between Brentford and Ealing at Ealing Rd, Windmill Road , Lionel Road as well as regular congestion in Boston Manor Road for the past few years along with so many road works near the Canal Bridge at Brentford High Street it makes it a constant problem for everyone and damaged businesses hugely.
