Infrastructure Crisis: Sewage Capacity

Operating at less than half required capacity

Bourton-on-the-Water's sewage treatment works has been identified as operating at less than 50% of required capacity.

This raises serious questions about accommodating any additional homes:

  • How can 227 new homes be served if existing capacity is inadequate?
  • What upgrades are committed and by when?
  • Should allocation proceed before infrastructure is secured?

What This Means

Bourton-on-the-Water would see 12% growth (227 homes). The relatively modest new allocation (38 homes) reflects significant constraints:

  • Entirely within the Cotswolds National Landscape
  • Extreme tourism pressure ("Venice of the Cotswolds")
  • Infrastructure constraints including severe sewage capacity issues

CDC's Own Evidence

The Council's own evidence base documents reveal key constraints affecting Bourton-on-the-Water. Use these findings in your consultation response.

National Landscape - Highest Protection

Bourton-on-the-Water is entirely within the Cotswolds National Landscape - the highest level of landscape protection in England.

The IIA states that developing within the National Landscape "breaks planning law". Only Scenario 6 meets housing need - but it is "contrary to national planning policy".

IIA Assessment Findings

The Integrated Impact Assessment identifies severe constraints:

  • Village already under extreme tourist pressure
  • Any significant growth would impact village character
  • Very limited expansion capacity due to National Landscape

Water Stress & Infrastructure

The IIA confirms Cotswold District falls within Thames Water's area which is classed as "seriously water stressed". Combined with Bourton's documented sewage capacity crisis (less than 50% of required capacity), this raises serious questions about any additional development.

"Significant adverse effects on water resources" are predicted under all development scenarios.

How to use this evidence

When responding to the consultation, you can cite these official findings to argue that Bourton-on-the-Water faces an exceptional combination of constraints: National Landscape protection, extreme tourism pressure, and critical infrastructure deficits. The Council's own evidence confirms that meaningful expansion is not sustainable.

No Neighbourhood Plan

No formal community plan

Bourton-on-the-Water does not have a Neighbourhood Plan. Given the village's unique pressures (tourism, heritage, infrastructure), the community has no formal mechanism to guide development priorities.

Key Issues for Residents

Sewage Capacity

  • Treatment works at less than 50% capacity
  • Can ANY additional development be accommodated?
  • What is Thames Water's upgrade plan?

Tourism Pressure

  • One of the most visited villages in England
  • Up to 1 million visitors annually
  • Infrastructure serves tourists AND residents

National Landscape

  • Entirely within protected landscape
  • Is any growth appropriate here?

River Windrush

  • Village built around the river
  • Flood risk considerations
  • Ecological sensitivity
