Comparing Slurry stores

[Chippy]

I know there’s been couple of slurry store threads but both are bit outdated. I’ve given up waiting for slurry store grant although I hear it might actually be finally coming this autumn. Even if grant comes and I get it, slurry store won’t be up till the winter of 2023 i would think so I’m just going to get on with planning etc. I’m still undecided on metal tower, concrete tower or concrete tank in the ground which I could eventually slat and roof and have another cattle shed one day. I’m looking at between 750,000 gallon and a million. Can people please share pictures and recent prices you may have had of these stores.

We have a tower and 2 underground tanks built with sheds. Concrete tanks are expensive and I would build them along with a shed as you can get the uprights set in easier at the time and levels right. There is expense just getting shuttering and the reinforcing delivered so an extra metered each way will not add greatly to cost. EA will not like outdoor slats in Cumbria as you have 1m + of rain to spread. You could have a smaller tank to scrape into or some channels in the passage which can then be pumped up to the tower. Ours holds 25000 gallons for 50 cows and would need emptied twice over the winter. 2 passages needs scraped. Another holds 80,000 and enough for 60 store cattle wintering in a 60x20 foot shed. No scraping or bedding required.
Should add the tower is 350000 gallons.

At least 750,000 gallon. Waiting to see what planning will let me get away with. Ideally 1 million

hi chippy! what way are you feeding your digester now? do you use your underground slatted tanks as storage and then feed the digester stale slurry? or do you keep them low and use them as a channel and feed fresh? we have recently put up a slurry store, mainly buried, with 4m panels and a roof (basically a grain store below ground level) !it worked out less than a steel store and will hopefully last even longer! it is worth specking your store to add a roof later, as when we done some silage pits a few years ago, the steel work wasn't compatable to use for a roof! also i was worried about having cattle above it due to any surplus metane content still in the warm digestate being pumped, causing problems?

I keep my underground slatted store low and feed digester fresh slurry but cows produce more slurry then digester will take so it ends up getting full and have to pump it to another tower where digestate goes
