Revised Draft Water Resources Management Plan 2024 and Statement of Response

We published our draft Water Resources Management Plan in November 2022 for a consultation, which closed on February 20, 2023. The draft plan set out how we intend to secure reliable, healthy drinking water supplies for the next 50 years.

We have now produced our statement of response, which sets out how we have considered and acted upon the comments received from customers and stakeholders. The response can be found by clicking on the links below:

Our statement of response is supported by our Revised Draft Water Resources Management Plan 2024 and appendices. These can be found by clicking on the links below:

Draft Water Resources Management Plan 2024

We published our draft Water Resources Management Plan in November 2022 for a consultation, which closed on February 20, 2023. The draft plan set out how we intend to secure reliable, healthy drinking water supplies for the next 50 years.

You can read our summary and technical documents below. We’re grateful for all the feedback we received. We’re reviewing this and we’ll publish a summary and any changes to our plan later this year.

Final Drought Plan 2022

On 1 April 2022 Defra confirmed we can now publish our Final Drought Plan 2022.

Legislation requires water companies to prepare and maintain a Drought Plan. Our Drought Plan is an operational plan that sets out the measures that we will take so that we are able to continue to maintain supplies of wholesome water to our customers with as little recourse as possible to Drought Orders and/or Drought Permits. The purpose of a Drought Plan is to set out the timely actions that a water company will take to ensure continuity of supply whilst at the same time continuing to protect the environment.

Draft Drought Plan 2021

We updated our Drought Plan and published a draft for consultation from June to August 2021. We’ve now reviewed the responses and published a Statement of Response which sets out the feedback and shows how we’ve updated our plans as a result.

The Statement of Response and consultation documents are available below:

Revised Water Resources Management Plan 2019 (December 2022)

Our Final WRMP19 shows how we will secure resilient water supplies to our customers for the next 25 years by considering how much water we have available today, how much we need to supply in the future and then what investment options are required to make up any difference.

Our previous Annual Review of the WRMP19, highlighted that in 2019-20 we had over performed in certain areas (leakage), but underperformed in others (PCC and the delivery of proposed groundwater schemes in 2019). We have therefore revised our WRMP19 so that we fully understand what our performance has meant in terms of our supply-demand balance for a range of scenarios all the way up to a 1in 200 year drought event. This is necessary in order to investigate whether there would be a security of supply risk to our customers during any of these drought events, and to the water we transfer to Southern during more extreme droughts.

The updated supply-demand balances demonstrate that we are no longer meeting our target headroom in a 1 in 200 year drought event, for the reasons highlighted in our previous Annual Review. This means there is an increased risk of us needing to implement severe demand restrictions in an extreme drought.

We have been working with the Environment Agency in the development of this Revised WRMP19, and will continue to do so as we progress through AMP7. This will include reviewing the most up-to-date data and knowledge that emerges during the development of the Water Resources in the South East (WRSE) regional plan and our WRMP24.

Final Water Resources Management Plan 2019

Your Water and Its Future

Thank you for helping us plan to ensure we can secure your drinking water for the next 25 years

Every five years we update our water resources management plan which looks at how we’ll keep your taps running while striking that delicate balance between protecting the environment and keeping bills affordable.

On 4 November 2019 Defra confirmed we can now publish our Water Resources Management Plan, which says how we will secure your drinking water for the next 25 years.

All water companies prepare Water Resources Management Plans (WRMPs) which show how they will secure resilient water supplies for their customers for the next 25 years. We consider how much water we have available today, how much we need to supply in the future and then develop options to make up any difference.

These plans are updated every five years to make sure they always reflect the latest information, innovation and customer views.

In preparing our plan we held conversations with customers and stakeholders over the last two years about your water supplies and what’s important to you and these have been taken into account in this plan.

We also have a Customer Challenge Group which has reviewed our work to engage with you and making sure your views are incorporated into all our future plans.

Here’s a quick summary of this plan:

  • This plan caters for growth and is part of a solution to supply other areas of the South East where there’s less water
  • We will do this by building a new reservoir at Havant Thicket – to store water, create a nature reserve and provide community facilities
  • We’re planning for more extreme droughts than we’ve known before – so we’re ready for climate change
  • We want to save water by reducing leaks by 20% over the next five years
  • We want to involve you in saving water with water meters, water-saving products and community campaigns
  • We have an ambitious target of reducing our domestic use to 100 litres per day by 2040.

Please take time to read our plan on how we’ll secure resilient water supplies in West Sussex and Hampshire.

In March 2018 we consulted on our Draft Water Resources Management Plan.

All your responses were shared with the Department for Environment, Food and Rural Affairs (Defra) and were considered by us when we develop this final Water Resources Management Plan.

We also produced our statement of response in which we have taken into account all the comments we have received from customers and stakeholders.

All of the detail of our Draft Water Resources Management can be found here.

We now publish our Final Water Resources Management Plan for the period 2020 – 2045.
