It is beneficial to find out at an early stage in the process how your proposed development could be serviced with a water supply, where your drainage system would connect to a foul sewer; surface water systems and is there adequate capacity in the receiving wastewater treatment works (WWTWs).
You will be told if development is within the development limit in proximity to a WWTW, and if the sewer catchment has negative capacity. There may be benefit in having this information before you submit your planning application or even prior to purchasing a proposed site as it may highlight potential issues early in the development process. This information can be obtained by applying for a PDE. For details on how to apply for a PDE, please see https://www.niwater.com/general/.
