Silage pit design

    As the title goes what do ye consider or have seen as a good design for silage pits?. Our current two pits have walls either side and are filled from the back off a ramp which is about 4 or 5 ft above the floor of the pit. Advantages being the contractor says its a good way of filling it and we start feeding from the high side so no water running down the plastic. they suited the fall of the ground but we are now outgrowing them so hope to put in for planning for new pits, whether they'll get done or not soon is up in the air but it would be so much done.
    The new pits will be going behind the old ones, I was thinking of having 3 pits - for two cuts of silage and one narrower one for maize or whatever else maybe bought in or grown. The idea with having separate pits would be to be able to access silage of different quallity for milkers, dries, yearlings etc and not have to be taking on and off covers for the second cut. Also do many of ye put in precast effluent tanks as it may be awkward to route effluent to the slurry tank here? Replies appreciated

    I like walled pits myself but would prefer if they are open either end so you can always use the oldest stuff first.

    A separate tank for effluent has merit IMO. But do bear in mind a wet year where you may have considerable volume to deal with. A submersible pump and a hose long enough to your tank would be an option if connecting to existing tanks via gravity is a none runner but should be factored into cost.

    Also bear in mind would. Extra storage be required for any new pit.

    A long narrow pit walled both sides and filled from the opposite end. Other than that keep it as close as possible to the sheds without making it awkward.

    Having it open either end would be handy alright don't see many around with three sides walled unless built into the rising ground behind it. Prefer walls also, what would be the highest lads would go with a pit? We've gone as high as the grab would reach but more because of being tight for space than anything else.
    Should be ok for storage volume and would try to put in drainage so when not in use or silage is covered rainwater would be diverted away. The submersible would be the most suitable to reach our slurry tank alrite.
