This map shows the location of sewage works that are owned and operated by Yorkshire Water . The data is divided into 2 layers, that can be toggled on and off. Larger Waste Water Treatment Works (WwTW) and Smaller Waste Water Treatment Works (Small WwTW).
You will see that some locations have a description of the type of treatment (decipher using below codes):

Developing within the Yorkshire Water service area presents a unique set of environmental challenges, from the industrial heartlands of West Yorkshire to the sensitive rural catchments of the North York Moors. Our localized mapping of Yorkshire’s sewage treatment works (STW) provides the critical evidence needed to navigate these constraints. Whether you are planning a residential conversion in Leeds or a new industrial facility in Hull, our "True Data" maps identify nearby wastewater assets that could impact your project's viability through odour restrictions or nutrient neutrality requirements.
Unlike flatter regions, Yorkshire’s diverse topography—including the Pennines and the Yorkshire Dales—significantly complicates Odour Impact Assessments. Hills and valleys create complex "downwash" effects and localized wind patterns that can carry malodours from a sewage works further than expected. By integrating our proprietary Yorkshire STW locations with site-specific terrain data and AERMOD modeling, we provide developers with high-accuracy odour contour maps. This ensures that residential receptors are positioned safely outside of the "Cordon Sanitaire," satisfying the requirements of local Planning Officers.
In recent years, Nutrient Neutrality has become a major hurdle for developments in specific Yorkshire catchments, such as the River Derwent and parts of the Tees. Our mapping allows us to identify exactly which Yorkshire Water facility serves a proposed development and what its current phosphate or nitrate permit limits are. By understanding the specific treatment capabilities of these regional assets, we can draft robust Nutrient Neutrality Assessment and Mitigation Strategies (NNAMS), helping developers unlock sites that are currently caught in planning embargos.
Yorkshire’s industrial legacy has left many cities with aging combined sewer systems. Our maps help visualize the relationship between new developments and existing infrastructure, which is vital for Foul and Surface Water Drainage Strategies. By identifying the nearest Yorkshire Water asset, we can advise on the feasibility of mains sewer connections versus on-site treatment options. This proactive mapping approach reduces the risk of "Section 106" delays and ensures that drainage designs are compliant with both the water utility’s standards and national environmental legislation.
Local authorities across the region—including Sheffield City Council and East Riding of Yorkshire Council—frequently require detailed environmental evidence regarding infrastructure proximity. Our Yorkshire-specific dataset acts as a professional-grade geospatial resource that supports your Planning Statement. By providing verifiable maps of Yorkshire Water assets, we prove that your project has considered all "Source-Pathway-Receptor" risks, from odour amenity to water quality. This level of technical detail is what has allowed SWEL to successfully deliver over 900 projects across the UK over the last 15 years.
