Study Notes

SuDS Manual Overview

The SuDS Manual provides guidance on the planning, design, construction, and maintenance of Sustainable Drainage Systems (SuDS).
This manual is relevant to both new and existing developments.
Its purpose is to promote effective SuDS implementation to manage flood risks and improve water quality.
It also highlights the importance of maximizing amenity and biodiversity benefits.

SuDS Manual Content

The manual covers various topics including materials, landscape design, maintenance, community engagement, costs, and benefits.
It draws upon UK and international good practice and research, incorporating practical experience from authors, project steering groups, and industry professionals.

SuDS Manual Key Message

The overarching message of the manual is to encourage the design of SuDS in a way that prioritizes the maximum opportunities and benefits derived from surface water management.
It emphasizes the importance of integration and collaboration in designing SuDS for urban areas, aiming to create high-quality spaces for future generations.

SuDS Manual 2015

This publication is the result of CIRIA Research Project (RP)992.
It provides guidance on SuDS components and the delivery of SuDS in various situations.
It includes how to plan for and manage extreme rain events for community resilience to flooding.
The Manual is primarily aimed at UK applications but will be of interest to all engaged in drainage work globally.
It recognizes the need for better information and engagement for those involved in the development process, from planners, landscape architects, designers, engineers, architects, and, in some instances, the community.
It is structured to allow for easy access, whether for a high-level appreciation of the concepts or detailed design guidance.
The authors are Bridget Woods Ballard, a principal engineer at HR Wallingford, with over 20 years' experience in hydrology and sustainable flood risk management and a key contributor to research on SuDS costs, maintenance, performance, and liabilities for regulators, the water industry, and other private sector organizations.

Applying the Approach

The SuDS design process includes setting strategic SWM objectives, conceptual design, outline design, and detailed design.
The process emphasizes stakeholder engagement throughout.
The manual provides guidance for designing for specific site conditions, including contaminated soils or groundwater, high groundwater levels, sloping sites, very flat sites, sites with potentially unstable subsurface rocks or soil workings, sites with very deep backfill, sites on floodplains, and for roads and highways.
Specific attention is paid to urban areas, outlining objectives for surface water management and offering case studies.

Technical Detail

The manual provides detailed design guidance for various SuDS techniques, including rainwater harvesting, green roofs, infiltration systems, proprietary treatment systems, filter strips, filter drains, swales, bioretention systems, trees, pervious pavements, attenuation storage tanks, and detention basins.
Each technique is described with general design considerations, selection and siting guidance, hydraulic and treatment design principles, amenity and biodiversity design considerations, physical specifications, materials, landscape design, and construction requirements, operation and maintenance needs, and relevant references.
The manual also includes information on pollution prevention strategies, inlets, outlets, and flow control systems, landscape design, materials, construction, operation and maintenance requirements, waste management practices, community engagement, and cost-benefit analysis.

Appendices:

The manual includes additional information in appendices, including contaminants in urban runoff and their potential toxicity, types of pollutant removal mechanisms in SuDS, SuDS performance data, groundwater protection evidence, and pollution prevention strategies.
