In light of recent environmental legislation, it has become necessary to focus on the responsible management of wastewater and animal waste. At COMANCO, we offer practical solutions that can help safeguard against runoff contamination, which may contain nitrates, ammonia, phosphorus, and bacteria, potentially affecting our waterways. These contaminants, when properly contained and managed, can also be turned into valuable nutrients for land use, ultimately reducing fertilizer expenses.

With a dedication to quality, COMANCO constructs lined and covered storage basins using the finest geosynthetic liner materials. These basins allow for the safe retention of liquid and semi-solid waste, enabling controlled disposal or land application. Additionally, our geosynthetic covered containment systems help curb odors and prevent contaminants from affecting the surrounding environment, providing a more responsible and eco-friendly solution.
