Farm manager Matthew Quinn explained that the structure will house a willow bed.
It is being completed as a measure through the Farming For Water European Innovation Partnership (EIP).
Other actions the farm has undertaken include the addition of hedgerows and fencing off watercourses.
The measure installed at the farmyard will collect any run-off water from the yard and filter it through the willow bed system.
The topsoil was stripped off the site and earthen banks were built up to form natural basins.
The weirs separate each section, and a system of pipes will allow water to move through the construction via gravity flow.
The earthen banks and bottoms of the basin were then re-covered with topsoil.
Willows will then be planted in the base of each of the basins, which will filter any sediment from the farm yard runoff.
The project is nearing the finishing stages, once final pipework has been installed and the willow saplings planted.
The Farming for Water EIP project is providing funding of €60 million to farmers to help improve water quality.
ABP suppliers from across the country have been availing of the support initiative to implement measures to help improve water quality in their relevant catchment areas.
