Private Life – When the Pond Came Inside June 17, 2016Posted by mwidlake in off-topic, Private Life.
This week my plans were thrown into chaos when our house flooded. Before I go any further I should state that everyone is fine, no structural damage was done and we were about as lightly flooded as you can be whilst still being, well, in the situation of having dirty, contaminated water in your home. Let’s just say our garden pond partially relocated into our house but brought with it a strong hint of Septic Tank.
I tweeted about it and my wife put some pictures up on Facebook and so people have been in touch to ask how things are. I don’t have a personal blog as well as this work-based one (and I treat this one as my personal blog anyway) so I’m putting some information and pictures up here. I won’t be mentioning Oracle or Office Politics.
So, why did our house flood? We live no where near a river. In fact, we live on a large, elevated plateau about 50 meters higher than almost everywhere 3 or 4 miles from here. But we do have a couple of square miles of clay-soil fields a few meters higher than our hamlet, just to the South of us. And the brook in our garden is part of the system that drains it. This has never been a problem in the last 10 years, even when it has rained solidly for a week. However, on Tuesday we had just over 2 inches (about 6 cm) of rain fall in about 30, 35 minutes. That is not a lot in some parts of the world, but in the South East of England, it’s very, very unusual. I’ve never seen rain like it in this country before, at least not lasting more than a few minutes of a “cloud burst”. I knew roughly how much rain had fallen as I had left a cup outside that morning, but one of the neighbours has a weather station and that accurately recorded it As I said, the soil around here is clay and it has been dry, so the rain did not have time to soak into the soil much. It just drained into the ditches and brooks…
It’s just like a database performance issue – it is not so much the volume of data you process but the speed at which you need to process it. Your physical discs can only write so much data in a minute. If you try and process too much, it all goes wrong.
When it was raining it was so extreme I actually took a couple of pictures and a video – before I was distracted by some water leaking through the roof as a gutter was being overwhelmed. I was really annoyed about the 3 or 4 liters that came in and that I had to mop up. Little did I know what was coming…
After the rain stopped I went and checked the brook and garden – it was fine. There was some standing water across much of the garden and it was flowing off into the brook and away. But then I saw one of the neighbours had a problem. There was water still flowing down the road and the brook on their side of the road was overflowing, it was threatening to get into their house. I went and got a spare sump pump I have but I could not find the attachment to put the pipe on it! By the time I had cobbled something together, the water was in their house. But the pump stopped it getting worse. Huzzah!
What I had not noticed was that my brook had been rising fast. I went back to my house to find I had a stream flowing past my front door. I’d never seen that happen before… Oh crap. The brook had filled my pond and it had overflowed one small section, where another neighbour had reduced the bank height whilst building an extension. (No, not on purpose and neither of us had realised it might be an issue). I went and got my pump (which was now redundant at the first house) but it can only shift about 5% of the volume going past the front of the house – It was not a raging torrent like you see on TV when major floods are reported, but it was a strong, steady, increasing volume of water that was creeping up the front of the house. Some spade work helped increase the flow and move the water on it’s way, I figured it would not breach the front door now.
I waded across the torrent (this was the point when the wellington boots become redundant as the water went past them and up to my knees) and checked the back garden, where the brook runs around the house. If it gets too high it normally overflows at one point and along a shallow depression which is there to take such unusual conditions. This was indeed happening – but such was the volume of water, there were pinch-points that have never been an issue before. The large tree you can see on the right is where that photo of the water going into a pipe is. Usually if the volume is too large for the pipe, it flows over the grass in a smooth way. Only this time it had a couple of “rapids” and was backing up towards the pond… And then the pond overflowed along several meters at once and I stopped taking pictures!
I now had a similar flow around the back of the house to the front and both were still rising. I could see it breaching our french doors into the lounge, it was almost game over. The first trickle has appeared and I could see the level creeping up
I checked next door and they had already flooded from the front (their house is lower than ours), with about 6 inches in the house. Would they mind if I increased the flow from our back garden to theirs, to try and stop us suffering the same fate? They graciously agreed to this so I set too with a spade and dug a drainage channel. It worked! Hundreds of gallons rushed away and the water level by those doors dropped below the threshold. Huzzah, let’s crack open the wine!
Only, why is there a large puddle growing at the other end of the lounge? In the centre of the house? Parts of the house are old, some bits of it go back around 300 years. We have internal walls that were once external walls. The water was coming up through the floor at one of these junctions, it was somehow getting under the house and in through this gap. Game over, I had defended the perimeters but been taken by a sneak attack from below.
Over the next hour or so the water leaked in through that gap and covered most of the lounge and hall carpets. I was able to move most things that could be harmed up off the floor. Another room at the back of the house (the base of a windmill) also flooded, this time through a door that I could not defend – but the floor is 6 inches lower in that room then the rest of the house. Again, I moved as much as I could but Sue lost some bits for making her hats :-(. The water never got more than about 2, 3 inches deep
The really annoying thing is that it was not just flood water with mud and dirt in it. Where I live we have no main sewer. We all have septic tanks or similar devices. When they flood the liquid contents get washed out. There were no signs of excrement floating on the water but the smell is very distinct. This is not water you want soaking into your curtains!
By early evening it was all over. The flow from the fields and down the brooks subsided and the pond level dropped. I pumped out the standing water next to the windmill and the water in the lounge (mostly) drained back down though the floor. I was up until about 2am using a carpet cleaner to suck up the worst of the water in the entrance hall – I knew I had to make that room passable as it links all the ground floor rooms together.
Since then it has been a case of ripping up the carpets and moving the stuff I could not move out of the places that got wet on my own. All carpets are now out of the house, most of it is in a skip. Now we are drying the rooms out and moving stuff again so we can move around the house and “live”. I’m not sure how many times I can empty a bookcase, move it and then fill it again with the books before I decide to stop reading books for the rest of my life 🙂
Our insurance company has been very good and all in all the whole flooding experience has been one of inconvenience than anything serious. I certainly would not like to go through it again and I think I know a couple of things I can do to help prevent it happening again.
So all in all, not a great week – but it’s only “stuff” that has been harmed and, in the great scheme of things, not a disaster. Just incredibly inconvenient. It will all be sorted soon.
