Wastewater from an AWTS can be discharged to a Land Application Area through drippers. It is important that the drip lines are correctly installed and properly maintained. To help ensure that the installation and maintenance is correct we have developed some guidelines. Check out Using Driplines for Wastewater Disposal.
