Where’s My Poo? The UK’s Sewage Problem

Isla Stubbs asks a very real, and very off-putting, question as we face an environmental sewage crisis.

The issue of sewage waste entering UK rivers and coastal waters has become a growing environmental concern, posing threats to aquatic ecosystems, public health, and the overall well-being of the environment. In 2022, UK rivers experienced more than 399,864 instances of untreated sewage discharge. This problem demands urgent attention and comprehensive solutions to prevent further degradation of our water bodies.

Sewage waste, loaded with pollutants and harmful substances, often finds its way into rivers and coastal waters due to inadequate infrastructure, ageing sewage systems, and overflow during heavy rainfall. This contamination adversely affects water quality, endangers marine life, and compromises the safety of recreational activities such as swimming and fishing.

The discharge of untreated sewage into water bodies leads to the release of nutrients like nitrogen and phosphorus, causing harmful algal blooms. These blooms deplete oxygen levels in the water, creating "dead zones" where marine life struggles to survive. The imbalance in ecosystems can have cascading effects on fisheries, biodiversity, and the overall health of aquatic environments. There is also the risk of persistent organic pollutants entering our surface waters unchecked, including pesticides, pharmaceuticals, and industrial chemicals.

Contaminated waters pose a direct risk to public health, as pathogens from sewage can cause waterborne diseases. Individuals engaging in recreational activities in polluted waters may be exposed to harmful bacteria and viruses, leading to illnesses ranging from gastrointestinal issues to more severe health complications.

Where’s My Poo Project

Amidst these challenges, the project is a newly emerged initiative that aims to raise awareness and crowdsource data on sewage pollution in UK waters. Here, you can enter your postcode or choose an area you wish to look at. By encouraging citizens to report instances of pollution, the project leverages community engagement to create a comprehensive map of affected areas.

The project's success depends on the active participation of concerned citizens, environmentalists, and policymakers to create a collaborative effort in monitoring and mitigating sewage pollution. To combat the issue on a larger scale, government bodies and water management agencies need to invest in upgrading and modernising sewage infrastructure. The implementation of advanced wastewater treatment technologies, improved stormwater management, and increased monitoring efforts are crucial steps in preventing further pollution.

Additionally, stricter regulations and penalties for industries and municipalities responsible for sewage discharge are necessary to create a deterrent against irresponsible waste management practices. Public awareness campaigns can further educate communities about the consequences of improper sewage disposal and the importance of water conservation.


The problem of sewage waste in UK rivers and coastal waters requires immediate and concerted action from both the public and private sectors. The WheresMyPoo project, as well as campaigns such as Surfers Against Sewage, serves as a commendable example of how technology and community involvement can contribute to monitoring and mitigating pollution. Through collaborative efforts, stringent regulations, and innovative solutions, we can safeguard our water bodies for future generations and ensure a healthier environment for all.
