We haven't had any serious rain for a couple of weeks now but I'm not worried about it just yet. I've still got almost 3 tonnes of water stored in basement which will keep us going for another month or so. Providing OH doesn't notice me pinching it we've another tonne or so in tanks outdoors.
I know this if off topic, but I have run out of rainwater and even "grey" water from the kitchen & bathroom. The long heralded "storm" passed through S.Essex tonight and did little more that still the dust, though it might have washed the panels a bit.
Have you ever posted "The Eric guide to the economics of rainwater harvesting and grey water re-use".
I am paying something like £1.30 a tonne and our friends in Brussels want to add to VAT to that. Many people, those in wetter parts of the country with mains drainage, are paying considerably more.
[I also pay a standing charge of approaching £40 a year for a 1/2" supply pipe.]0 -

Afraid not - although have been known to communicate with other MSEfolk 'off forum'.
People like CAT have ensured that there is plenty of material on the subject available.
Briefly, the savings offered by commercial rainwater harvesting installations probably don't give an acceptable %ROI. I make it work by using recycled components where possible. In particular IBCs (one cubic metre plastic tanks on a pallet) can sometimes be acquired for pennies - if nobody else viewing that well known auction site wants one at the same time as you do.
You also need to have a good idea of your water usage and the likely rainfall in your area when deciding on tank capacity. I thought I'd worked it out nicely with my initial installation of 2.5 tonnes but after a couple of two week 'gaps' in the early years I added another couple of tonnes.NE Derbyshire.4kWp S Facing 17.5deg slope (dormer roof).24kWh of Pylontech batteries with Lux controller BEV : Hyundai Ioniq50 -

Against all the odds, we did indeed get some rain last night - in fact it started raining a few minutes after I posted that message
That isn't of course quite the timing that the forecasters (some of them - others ignored possibility) said.
Even after today's pumping (the sun is shining here - again that's going to come as surprise to the forecaster that said it will be dull until 7pm !) tanks are still at 80% capacity.NE Derbyshire.4kWp S Facing 17.5deg slope (dormer roof).24kWh of Pylontech batteries with Lux controller BEV : Hyundai Ioniq50 -

Only some rain last night? Woke my 2 kids up it was bouncing that hard. Coupled with the thunderstorm we had this afternoon, my waterbut is overflowing now.
Managed 13kWh yesterday but only 8 today. Oh so not many O's:D2 kWp SEbE , 2kWp SSW & 2.5kWp NWbW.....in sunny North Derbyshire17.7kWh Givenergy battery added(for the power hungry kids)0 -

Yes, only some. Collected around 300 litres from 100 sq m of roof. I make that around 3mm of rainfall.
In fact I've collected more than that since 9am today (around 4mm of rainfall).
And weather has obviously been different across here lately - we've generated 12kWh today.
I suppose every cloud system has to have an edge somewhere and it looks like you were less than 10miles from the edge of yours. I would say how difficult that must make life for forecasters - except that they claim they can work to that level of accuracy.NE Derbyshire.4kWp S Facing 17.5deg slope (dormer roof).24kWh of Pylontech batteries with Lux controller BEV : Hyundai Ioniq50 -
