DWMP meaning

Although the guidance is not statutory, it is comprehensive and, at times, couched in obligatory terms, and in places stated in mandatory language. Unsurprisingly, it provides direction on the legal obligations the guidance engages with, on consultation, on the environmental assessment of options, on the statutory annual review of the DWMP, and on how it interfaces with other plans. Taken together, the guidance comprises three documents in all: a short introductory paper touching on key issues that arise when preparing DWMPs (‘doc1’); a detailed, step-by-step ‘how to’ guide setting out the process (‘doc2’); and a set of thresholds for reporting purposes, in addition to the undertakers’ performance indicators (‘doc3’).

Every sewerage undertaker must produce, publish and keep up to date a drainage and wastewater management plan (DWMP). This is a long-term plan to manage and develop the undertaker’s drainage and sewerage systems so that it can meet, and keep meeting, its WIA 1991, s...
