Introduction
Effective water management is a critical aspect of any development project in the UK. A Drainage Strategy ensures that surface water and foul water are managed sustainably, minimizing flood risks and protecting water quality. For developers and landowners, incorporating a well-planned drainage strategy not only fulfills legal requirements but also supports environmentally responsible development.
This guide explores the essentials of drainage strategies, focusing on best practices, legal standards, and practical steps to create one. Learn how Enviro-Reporter can streamline the process to ensure your project meets planning requirements efficiently.
What is a Drainage Strategy?
A Drainage Strategy is a detailed plan that outlines how surface and foul water will be managed on a development site. By using Sustainable Drainage Systems (SuDS) and following the drainage hierarchy, these plans aim to manage water sustainably while mitigating flood risks.
- Sustainable Drainage Systems (SuDS): Natural methods like swales, ponds, and permeable paving to manage water effectively.
- Drainage Hierarchy: A set of priorities for water management, starting with infiltration and ending with sewer discharge.
- Foul Water Drainage: Addressing how wastewater is safely discharged to the sewage network.
A comprehensive drainage strategy ensures compliance with planning requirements while promoting sustainable development.
The Process of Creating a Drainage Strategy
1. Site Analysis
The process begins by assessing the site’s characteristics, including soil type, topography, existing drainage systems, and flood risks.
2. Drainage Design
Based on the analysis, engineers design a drainage system that aligns with the site’s needs and local planning authority requirements. This includes SuDS features like soakaways and attenuation ponds.
3. Calculating Runoff and Storage
Using tools like the MicroDrainage software, the strategy calculates surface water runoff rates and required storage volumes to ensure compliance with national guidelines.
4. Integration with Landscape and Infrastructure
The drainage system is integrated with the overall site layout and landscaping to maximize aesthetic and environmental benefits.
5. Reporting and Submission
The completed drainage strategy is compiled into a report and submitted alongside the planning application for approval.
Legal Requirements and Planning Implications
UK development projects must adhere to stringent regulations governing water management. Key requirements include:
- National Planning Policy Framework (NPPF): Mandates the use of SuDS on major developments.
- Local Planning Authority Standards: Requirements may vary by council but often include specific SuDS features.
- Flood Risk Management: Drainage strategies must consider the risks posed by climate change and increased rainfall.
Without a drainage strategy that meets these standards, planning applications may face rejection or costly delays.
Practical Advice for Developers
1. Start Early
Initiate the drainage strategy process early in your project to identify potential constraints and design around them.
2. Conduct Soil and Topography Assessments
Perform site investigations, including soakaway tests and groundwater assessments, to determine the best drainage solutions.
3. Incorporate SuDS
Prioritize sustainable methods like green roofs, rain gardens, and permeable surfaces to manage water naturally and efficiently.
4. Collaborate with Experts
Work with qualified drainage engineers and consultants who understand local and national guidelines.
5. Engage the Authorities
Proactively consult with local planning and flood authorities to ensure smooth approvals and compliance.
