Overground slurry storage

At what volume does overground become more financially attractive than underground?

The further away an underground tank gets from square the less attractive financially it gets. Say a tank 100ft by 10 ft is 220 ft of wall and 1000sq ft floor space. A square tank of 55ft x 55 ft, the same length of wall, will give you 3025 sq ft floor space, and over 3 times the slurry storage, the height of the wall remaining constant. Factor in the cost of getting the slurry into the over ground tank, the rainwater that will have to be disposed. Slats against scraper. Round steel or concrete tank,HDPE lined lagoon. Ease or difficulty of agitating. There would be smoke coming out of the back of the calculator.:D

i have an overground and one thing it holds a lot of slurry 150-200k of slurry but between pumping up the slurry and rainwater id prefer an underground anyday. Also its beside a stream so it could be dangerous too!

just do it

Surely there's a generally accepted volume where overground becomes more attractive?

I have no slurry storage here. And im going to need enough for 150 cows and followers. One shed i can put in a tank and cubicles for 70 cows because it has no floor it. But for the rest im thinking of overground.

I have a finrone overground steel tank 160 k gallons as well as underground tanks which can all be pumped into it.for me it wasn't a volume thing rock is very near the surface and to dig an underground tank I'd have to get a rock breaker in or blast.personalky I'm a fan of overground tanks v underground.slurry comes out if overground a bit thinner than underground making it easier to mix.i could also add another rim to it which would add another 60 k gallons of volume for smallish money.if I was building it again I'd put an aeration system in it and that way slurry is always ready to spread

and you havnt had penalties as of yet, what an utter joke the way Nitrates is regulated. Penalties galore in this county.


What are you getting away with saying - that you have straw bedding or some such lark

I wouldn't panick about storage or inspections , even a small loss on a sfp every year wouldn't vcover the costs of complying.

A couple of ring feeders will feed a lot of stock with no worry of storage limits.

Inspectors need the work, there people too ya know.

got penalties every year bar this year. All straw bedded here. Clean out passage ways 3 times a week and clean out sheds twice in winter. Spread all that in spring, clean out sheds when thats all spread and spread in autumn. Works okay apart from run off

How muchys of a penalty?

Have you done costings on it? If you've to go overground for some of your requirement, why not go overground for all of your requirement? Is it a thing that you need a tank to fill first before pumping into the overground tank?

Just getting my head around the thing. Will need extra slurry space in a year or two and just think with a well placed overground tank it could allow for future expansion.

how much did that cost to build ?

did you consider concrete at the time rather than steel ?

Timmaay

I haven't done out the costings myself either, but will need about another 60kgls. Best thing about underground is it saves space, and very simple, no need to mess around with pumping the slurry up, just call in the contractor to agitate and spread it twice a year. The price of concrete and labour for a tank has dropped alot, I'm thinking a 10ft deep, 14/16ft wide, and maybe a double tank if it made sense would be my best bet. My biggest problem is actually the opposite to mahoney, the ground under the yard here is very wet clay, last time we dug out an 8ft tank we had alot of walls caving in, so 10ft is going to be even more of headache.

just do it

A jeez Timmay you've just thrown a curve ball in with you're 10ft tank! I've heard of 9ft but not 10ft. any trouble agitating to that extra depth?

Timmaay

I think it was on boards I 1st read about it, afew lads have gone that deep. Actually did Stan stay he is going 9ft6 with the tank in his new shed? I don't think agitating is a problem, unless you are trying to mix up only say 3ft at the bottom of the tank, which in fairness its a waste of time trying to mix up just than amount in any tank. Biggest issue with going that deep is suppose to be sucking out the slurry, take the likes of a 2600gls tank, which is going to be a good 8ft tall, if your sucking from the bottom thats a full 18ft of lift you need to bring the slurry up, hard on most vacuum pumps. The trick here would be to have an area afew ft lower than the tank, that you can reverse in the slurrytanker and suck from a lower point.

Suck from a lower point, tim?
You should rephrase that haha

done no casts on it at all but it would have to be cheaper than digging out sheds and getting in a rock breaker.

What way do tge lads here run the over ground tanks? Hiw many times a year do they pump the slurry?

mahoney_j

I pump slurry into mine about once a month.from just before Xmas till maby late march.from mid jan on maby less as I try and spread as much through the spring as I can.never under pressure to try and sneak a few loads out due to tanks been full.slurry cones out of it a bit thinner as well which is a good thing as it gets into grass that bitcquicker

It was done in the days of the grants when my dad was running the show.will try and dig out some paperwork and get back to you.didnt consider concrete at time due to cost,with the finrone I can add another rim which gives another 60k gallons for reasonable money.

I got a quote from a northern Irish precast concrete tank company for a 20m diameter x 6 meter high tank, about 6 months ago. (414, 600 gals or 1884 cubic metres). Have to dig out and stone the area myself. 47,500 euro. They do the rest.
That was for west cork. They'd knock a few euro off that the closer you are to the border.

There is a point where physics comes into it. And no tankers vaccum pump can suck. You need a special gear type pump like u see on the huge tankers on the continent. I have small tank at over 12' and it can suck the last bit with an empty tanker but cant fill the tanker from the bottom

st1979

I have an outdoor concrete lagoon 8-9' deep slurry is auto scraped in. But it is a bit un safe. So also want more storage and increase safety. So am in the future going to add on a 6' wall all around and pump slurry in. Put a pipe through the wall like an overground tank to suck slurry. Only issue is agitation can only see an aeration system working

With past experience of doing this the problem is the slurry left in the hose once the tank is full you have to lift it back above the pit to get the slurry to flow back, so its not spilling all over the place or causing a syphon effect and letting the slurry flow down your yard

How many cows slurry does that tank hold? Do you put a pipe on your agitator and pump it that way?

47.5k is that +VAT ?
digging and stoning is one part
is there a concrete slab on top of that as well to be funded by you as well ?

reason for asking the cost is have heard of steel tanks costing 70-80k but no idea of size

levelled an old slurry pit and dug out this year and built a 60ft*60ft*10ft deep to give a capacity of 220k gallons. 8 of the 10ft is underground, there will be a bit of emptying in it with a 1300gal tank

complete with a homemade slurry safe (concrete) between digging, steel, trunking labour, surrouding fence etc the whole lot cost v close on 30k mark VAT included

My price was 47, 500 plus vat. They just wanted a stoned base. They pour the base and erected the panels.
