The process we’re following to develop our DWMPs is:
The final DWMP programme is then fed into the development of our Business Plan for the next price review period (PR24).
Risk based catchment screening
Risk based catchment screening (RBCS) is a process completed at the outset of developing a DWMP. It’s used to identify where a sewer catchment has a current and/or potential risk or vulnerability, so effort to can be focused on understanding the risk and why it’s likely to occur.

The Water UK guidance sets out the need to establish planning objectives for a long-term planning horizon. These will be developed during the 'strategic context' stage. Find out more about planning objectives:
The water-sector regulator, Ofwat, has set a timetable for delivering the first round of DWMPs. Though challenging, the timetable is necessary so our DWMPs can be used in the development of our business plan for the next price review (PR24).
The timetable is also driven by the need to inform the National Infrastructure Commission’s second National Infrastructure Assessment (NIA) into the state of the water industry’s infrastructure, due for publication in 2023.
The key dates for the development of our DWMPs are:
Our delivery schedule
We’ve considered the activities, sequence and resource requirements in detail. Based on this, we’ve developed an indicative delivery schedule for the delivery of the first round of DWMPs – shown in the Gantt chart below. We consider this realistic and achievable and it meets Ofwat’s timetable:
The timetable for the delivery of the first round of DWMPs is a significant challenge. We understand what is involved and our detailed programme has considered how we will deliver the DWMPs. We’ll work hard to provide a good first set of DWMPs for our region to support our work with partner organisations, customers and our business plan for the next price review (investment) period for 2025 – 2030 (known as PR24).
Giving our partners and customers a say
We’ve scheduled a period of three months for the final public consultation and three months to respond to the consultation and finalise our plan. This will allow our partners and customers to have a final say on our first DWMPs before they’re published, as well as providing an ongoing mechanism for them to continue to have a say in our planning and investment decisions during implementation.
We’ll complete the first round of drainage and wastewater planning for our operating region by the end of January 2023. These final plans will be available in early 2023 to inform PR24 business plans.
Links to other plans
Several other plans will inform our DWMP – including plans from other organisations with responsibilities for drainage, water management and protection of the environment, including:
- River Basin Management Plans (RBMPs)
- Flood Risk Management Plans (FRMPs)
- Local Flood Risk Management Strategies
- Surface Water Management Plans
- Local Plans (for future development and social change)
- Water Resource Management Plan (WRMP) and Drought Plan
We will create strong links to these statutory and non-statutory plans, so our DWMPs consider wider objectives and future needs, and our decision making and timing of delivery is co-ordinated where possible, especially where we can work in partnership to jointly fund and deliver schemes.
In addition, our DWMPS will be supported by the key programmes within our Business Plan for 2020–2025:
- Target 100 – Reducing average daily consumption to 100 litres per person.
- Catchment First – Ensuring catchments are at the heart of decision making and delivery
- Networks 2030 – Creating a more resilient supply network for future generations.
- Resource Hubs – Transforming wastewater treatment works into community assets.
- Sustainable Drainage 2030 – Creating capacity across the sewer network.
Our DWMP will also demonstrate where proposed activities may have a significant impact on other plans – for example, nutrient management plans and diffuse water pollution plans.
