The previous waste storage facility at this farm was not meeting the needs of the expanding operation. They needed something larger to reduce chances of running out of storage and having a waste runoff issue. The storage pit being constructed will be approximately 12 million gallons. The project was partially funded with DATCP SWRM funds.
One major challenge has been that they are constructing a new housing facility, waste transfer system and waste storage facility. Making sure everything fits together and that all contractors are on the same page has been important.
Weather has also been difficult with snow and then rain (making sure concrete was staying protected from the cold and that the rain did not damage slopes or sub-soil or concrete).
