Housing Development Planning: Water Companies

Edward Morello Excerpts

Wednesday 12th March 2025 Westminster Hall

[Edward Morello (West Dorset) (LD)]

It is a pleasure to serve under your chairship, Mrs Lewell-Buck. I congratulate my hon. Friend the Member for North Shropshire (Helen Morgan) on securing this important debate.

For too long, our rivers, streams and seas have been treated as a dumping ground for sewage. Water companies have failed to maintain and invest in the infrastructure necessary to protect our natural environment. This has a devastating effect on local residents, businesses and tourists, who rely on clean water and unspoiled landscapes.

It is clear that the current system is failing and that urgent action is required, which is why we must make water companies statutory consultees in the planning process for all new housing developments. Currently, water companies are not required to be consulted when new housing projects are proposed; it is merely best practice. That is a glaring omission, considering the fact that the waste water and sewage from new developments will inevitably place further strain on an already struggling system.

The consequences of failure can be seen across the country, including in my West Dorset constituency, where sewage pollution has reached crisis levels. In 2023 alone, West Dorset experienced more than 4,100 sewage spills from storm overflows. Of the 500,000 hours that my constituency neighbour and hon. Friend the Member for Honiton and Sidmouth (Richard Foord) said the south-west has suffered, our beaches and rivers suffered 45,000 hours of sewage discharge from the existing degraded sewerage and water system, tarnishing the landscape that makes my region so special. The River Lim, which flows into Lyme Regis, was declared ecologically dead due to the severe pollution it has suffered. We are aware of that only thanks to the efforts of the citizen scientists of the River Lim Action group. This state of affairs is simply unacceptable.

West Dorset is part of the Poole catchment area, where an excess of nitrogen has had a disastrous effect, leading to significant reductions in biodiversity. Without proper infrastructure, any new homes built in the catchment area will only add to the pollution burden. We must ensure that the impact of the waste water from new developments is properly managed. The Governments’ nutrient mitigation scheme is a step in the right direction, but it cannot be the only answer. Water companies must be consulted from the outset to ensure that sustainable infrastructure is in place before new homes are built. Without that, we risk compounding an already dire situation.

The Minister issued a written statement on 10 March 2025 about the reform of the statutory consultee system. That provides an opportunity to review the role of water companies in the planning system. If the Government are serious about tackling the sewage crisis, they must seize the opportunity to ensure that water companies are statutory consultees, without delay.

This is not just about the environment; it is also about our local economy. Tourism is a vital industry for West Dorset. Visitors come to enjoy our beautiful beaches and waterways. It is unacceptable that residents and tourists must check pollution alerts before they can swim. If we do not act now, the economic consequences for my area will be severe, and local businesses and communities will bear the brunt.

We need real accountability and meaningful change. Making water companies statutory consultees will help to ensure that new housing developments do not further damage an already failing system. It will bring transparency to the planning process and force water companies to take responsibility for the new infrastructure planning that is essential for our environment, for our economy and for public health.
