The Rain Never Stops: Water Harvesting at Hedera

23 Jun, 2025

They say if you don’t like the weather in Yorkshire, wait five minutes. Then fetch a brolly. And once Hedera Cottage is ours proper on the 4th of July, we’ll finally have somewhere to put all that rain.

Why Will We Be Catching Rain?

Well, firstly – it’s free. Can’t argue wi’ that. And since the plan is to take Hedera partly off-grid, it makes sense to start catching the sky juice instead of paying for it by the litre. It won’t just be for the garden either – with the right setup, we’ll be able to use it for flushing loos, washing mucky paws, and even doing laundry.

(Though let’s be honest – Yorkshire Tea deserves better than roof dribble.)

The Setup We’re Planning

Once we’ve got the keys and cleared away whatever’s nesting in the downpipes, we’ll be putting in a few hefty water butts round t’back. Eventually, we’ll work up to something fancier – proper tanks, maybe hidden underground so the spaniels don’t try and paddle in ’em, and a good filter system to keep the green floaty bits out.

We’ve already had stern words with Lexi about not retrieving drowned voles from the gutters. Let’s see how that goes.

Filtering the Gravy

Rain off a slate roof might look clean, but it’s got all sorts in it – bird offerings, mossy scraps, a bit of atmospheric flavour. We’re planning:

  • First flush diverters to chuck the first mucky water away
  • Mesh screens to catch the lumps
  • Maybe a charcoal filter if we get fancy

We won’t be bottling it for posh houseguests just yet. Unless someone wants to try “Essence of Roof” – Hedera Edition.”

Will We Drink It?

Technically, it’s possible. Realistically? Not straight away. But for watering plants, rinsing boots, and flushing the thunderbox – ideal. And far more dignified than lugging water about in a wheelbarrow when the taps run dry.

Forecast: Mostly Moist

Based on many years of personal dampness, Hedera’s likely to get somewhere between “mizzly” and “biblical” weather for at least 220 days a year. That’s plenty to keep a few tanks gurgling away – as long as we store it right and don’t lose half of it in leaks or mischief.

What We’ll Be Doing After Completion

  • Installing underground tanks (posh word for big buried tubs)
  • Setting up irrigation for the future veg patch
  • Possibly piping water into the house for non-drinking use
  • Explaining to Kira that standing in the overflow doesn’t count as a bath

How to Teach Your Mac to Spot Rabbits (and Other Garden Visitors)

Most folks with a trail-cam know the problem: you get thousands of clips and photos, and 90% of them are wind-blown grass, pigeons’ bottoms, or the neighbour’s cat. Lovely, but who’s got time to sift through all that? At Hedera Cottage we built a “robot librarian”...

You know that little shed full of humming boxes and blinking lights? Turns out the daft human’s been teaching them to recognise me garden visitors. Every day, the trail-cams spew out thousands of clips and photos — fox-coloured blurs, pigeon bottoms, the odd neighbour...
