Assessment of dispersed pollution is addressed using a geographic information system data model for representing geographic objects or surfaces as data. The model can be formulated in a way that it can map the critical locations for dispersed pollution; it identifies urban or rural areas which pose the most danger to receiving water bodies and also evaluate the impact of land use changes on rainfall runoff quality.
One issue with UUD is the complexity of the existing populated area; rebuilding the drainage in a built-up area is a complex task and the most pragmatic solution is mixing both conventional and UUD. This mix has lessened diffuse pollution and flooding in Europe, North America and UK.
The implementation of UUD from our partner Evzin & Associates, involves a variety of stakeholders that work within planning and regulatory framework.
A project of UUD is evaluated against multi-criteria and multi-objectives placed within an overall decision support framework, known as DSS (Decision Support System).
The multi-criteria and multi-objectives from UUD from Evzin & Associates are:
Social Benefits - Amenity and Aesthetics Public Information and Awareness Stakeholder Acceptability Health Risks.
Economic Factors - Financial Risks and Life-Cycle Cost.
Environmental Impacts - Water Volume Impact; Water Quality Impact; Ecological Impact; Resource Use and Maintenance.
Technical & Scientific - Performance System; Reliability System; Durability System and Flexibility & Adaptability.
