#backyardProject #PoolPond Update!

Since getting the liner in at the end of November I have been patiently waiting for the holes to fill with rainwater so that I can confirm and if necessary adjust the level of the edges and the overflow points.

#1 The pump intake bay filled first and is emptying into the main pool as desired (the water will be drawn *into* the bay when functional). I’ll adjust exactly how and where the water is drawn in with rocks.

#2 The bog filter hole is almost full now. Hopefully today’s rain fills it. By all appearances it should empty from its southwest corner closest to the main pool as desired. There is lots of extra liner to deal with in that spot so it’ll take some refining to make it nice.

#3 The last will be the main pool. If all goes as expected, it should overflow somewhere on the long edge. It should be overtop the wall of the bay but not overflow the bay or the short edges. I want the overflow to be closest to the house drainage system which is under the chicken coop at the top edge (left corner in the first pic).

The ponds themselves look good. The water has flattened the liner to the bottoms and sides (and steps of the pool!) which should help solidify things. No leaks detected. The liner doesn’t have too many extra folds in the holes which is good.

When I get rocks to make the inner pond wall I will probably start by putting flat stone along the bottom to protect the liner and keep it flat.

Of course… before I do that, I need to deal with Dirt Mountain, finish the fence, and remove the car.

But for now… I like how still the water is. #silentsunday

Two large ponds are visible covered in black rubber material. Closest is the bog filleted pons. It is about 30cm from overtopping in one corner closest to the larger pond which is about 60cm from full. There is a halzelnut tree just on the other side of the filter pond between it and a smaller pump bay. In the background is a yellow cover over a car.
A view from the opposite direction shows the main pool pond and the bay to the left. The hazelnut is reflecting in the water of the pond.
A look down into the end of the pool pond shows some sediment settled on the bottom but mostly the black liner stuck to the sides and bottom in folds and ridges through the clear water.

I unraveled the other bundle of liner in the wrong direction which led to a more huffing and puffing, but, the deed is done!

I shall now continue battling with the rain gods to keep it reasonably empty of water, except to see where overflow points are.

Next: Get a big load of large rock (12-18" stones) to line the inside wall of the pool/pond and start filling the filters of the other two. Also time to think about plumbing design!

Oh! And Mr Arbutus is very happy! #pondpool #backyardProject

Initially, pulling the liner over the hole. The liner troops down partway into the hole.
The finished liner is in and shoved up the side of the hole. The edges are behind with the liner, all flipped over on itself with extra.

Big thanks to @RandomCanuck for finding a CO2 answer!

This document (epdmroofs.org/wp-content/uploa) says standard 60mil* EPDM roofing membrane embodies 6.93kg of CO2/sqft.

So 45mil (1.143mm thick) will be 25% less:
6.93-25% = 5.198 kgCO2/sqft.

I bought a 70ft x 30ft section.
So 2100sqft x 5.198 = 10,915.8 kgC02**

That is equivalent to flying from #YVR to #HKG roundtrip, 13 times. Oooooff. That's a bit of a shocker. 🫢😐

OK, I guess I have some work to do to offset/capture some carbon in this here little pond/pool! The good news is, it will not feature any fish so I am hopeful that it will be, eventually, a carbon-negative operation as long as I plant it chock-full and periodically remove/sequester the compost to avoid methane emissions from decomposition.

*WHAT A STUPID MEASUREMENT lol “60mil” = 0.060in or 1.524mm thickness

** Holy heck I love the built-in math in the latest macOS/iOS update!!

Here's some info I found from Dow on a new process they say *reduces* various polluting factors by ____% but of course they don't give absolute numbers because then we would have actual information. 🙄

Just bought a lot of rubber….

Technically... I guess this is the largest carbon-purchase I've made in a few years, at least since I last flew a long distance. Now I'm curious on the carbon footprint of EPDM rubber materials. I'll have to go googling for the embedded carbon in rubber later.

Firestone PondGard or Carlisle brand 45 mil EPDM pond liner Choose the size you require from the dropdown menu below Any width with a length of 50 feet or 100 feet is sold by the roll and pricing is $1.59 per square foot Any other size has to be cut from a roll and is $1.59 a foot Not suitable or approved for roofing applications Our regular shipping & handling fee schedule does not apply to pond liners. Pond liners are heavy and therefore more expensive to ship. As such, shipping charges for pond liners are quoted separately. Please place your order, and we will get back to you with a firm freight quote or inquire before placing your order. ORDERS REQUIRING EXTRA FREIGHT CHARGES WILL ONLY BE PROCESSED ONCE YOU APPROVE THE FINAL INVOICE AMOUNT. Please see our Pond Liner Shipping Information page for additional information. Pond Liner Sizing Measure from a Plan Length of liner required = Max. length of pond + (2 x max. depth of pond) + min. 2 feet (min. 60 cm) overlap Width of liner required = Max. width of pond + (2 x max. depth of pond) + min. 2 feet (min. 60 cm) overlap Measure Off of a Completed Excavation If you are measuring off a completed excavation, use a flexible measuring tape or a rope that completely conforms to the contours of the excavation. To determine the full length of liner required, run the tape or rope down into the pond, exactly following the contours of the excavation, across all the ledges, to the bottom of the pond, and back out the other side. Then add at least 2 feet or 60 cm (minimum 1 foot or 30 cm per side) to allow for sufficient liner overlap outside of the pond. Use the same method to determine the width of the liner. Be sure to measure across the maximum length and width and at right angles to each other. Example Using one of the above formulas and including a minimum liner overlap of 2 feet (60 cm) for both length and width, you determine a required liner size of 19' x 23'. Now all you have to do is select from either Firestone or Carlisle and look for a suitable size. In this case, the only suitable liner size is 20' x 25'.  Warranty Firestone Pond Liner features a 20-year warranty if installed to manufacturer recommendations. One recommendation not to overlook is using a fabric underlayment to increase puncture resistance. If an underlayment is not used the warranty may be voided.

Someone suggested mudstone or siltstone. This seems right. The more I dig and scrape at it the less I think it is some sort of old fill. When it is dry in the hole it is grey. There are lots of shards of carbon-like black stuff. But mostly it is grey, crumbly when knocked around, rock.
Here is this morning's look in the hole.

Whatever it is, it is too much for this digger to dig through efficiently.

The bottom of the hole shows a scraped side meeting a scraped bottom. It is grey earth with red and brown clay above.

This is a special #LabourDay for me as I am getting a little experience in the heavy mechanical trades! (Don’t worry I am doing it on my day off for fun!)
Just a reminder that all work should be valuable and valued! If you want to watch me make holes in the ground, and apparently find bedrock, tune in! I’ll be starting at 7AM!

Hey #GeologyMastodon may I get an assist in identifying this rock?! I believe I have hit bedrock about 1 metre down in my #BackyardProject #PoolPond excavation.

It is a light grey to brown but has shiny black surfaces (I thought at first it was a bit of coal!) that can be scraped away with a fingernail. It flakes apart fairly easily but it is quite hard. It's definitely going to be the bottom of my hole!

We are on #VancouverIsland in #PortAlberni
#Geology #Rocks

A rock sits on a white sink. It is a sort of rectangular irregular shape. It is mostly brown with black patches. There is a smaller shard to the right.
The same two rocks sitting beside each other.
A closer view, the rock is glistening with moisture.
