Slurry Pit
A slurry pit is a structure specifically built for storing slurry. There are four most common types:
1) Open slurry pit
This is simply a rectangular concrete tank built in the ground. Around the top of the tank must be fenced to a height of 2m (6'6") in order to prevent a child or livestock from falling in. Slurry usually flows from a channel into these tanks.
2) Slatted slurry pit
A slatted pit is similar to a open slurry pit except that the top of the tank is covered with concrete cattle slats. The tank width is normally sized to match the length of the slats so that they span the tank perfectly. Some slatted tanks are built indoors as part of a slatted unit. Some of the precast slats have a steel opening section in order to agitate and remove the slurry.
3) Overground steel slurry pit
These are normally circular structures, built from a series of curved metal panels which are bolted together to form the walls. The floor is normally a concrete slab. As these structures are overground, the slurry must be pumped into them every week or so from a nearby receiver tank.
4) Slurry lagoon
A slurry lagoon is a large pit which is excavated out of the ground and is then subsequently lined with a suitable liner material. They are cheaper than the other 3 options, however they do have their own advantages and disadvantages. These also have to be fenced to prevent children and livestock from falling in.
