Urban Drainage (An Introduction for Non-Engineering Professionals)

Home>In-House Training Courses>Drainage & Hydrology

This course is targeted at non-engineering professionals involved in land promotion or land development to raise their awareness, knowledge and understanding of drainage, and to provide non-engineering professionals with an appreciation of the drainage matters that need to be considered when promoting or developing a site.

This course includes the use of online tools produced by HR Wallingford. To ensure the course remains as productive as possible, delegates will need to visit HR Wallingford's website and create a free account for use on the day. A login and password can be sought by signing up via https://www.uksuds.com/.

Also available as an online training course.

Please note that the online version of this training course will be split into modules.

Overview:

The course will examine the constraints and opportunities presented by drainage when developing a site. It will consider both piped networks and Sustainable Drainage Systems (SuDS) and how they can be integrated into a site masterplan.

The requirement and contents of a Flood Risk Assessment and foul and surface water strategies will be explained together with associated matters such as adoption, maintenance and the inspection of existing systems.

The course will also provide checklists to assist non-engineering professionals to review engineering drawings to ensure that the salient matters have been considered.

Aims & Objectives:

The course will enable delegates to develop a deeper understanding of foul and surface water drainage and its incorporation into land development proposals. It will:

· Explain how existing drainage systems can be traced, surveyed and recorded

· Outline how underground pipe networks are designed and operate

· Consider the need for Sustainable Drainage Systems

· Discuss the key drainage issues and ensure that they are integrated into a development masterplan

· Outline the approvals, permissions and agreements required by drainage systems

· Explain Flood Risk Assessments, foul and surface water strategies

· Discuss adoption and maintenance strategies

· Provide checklists to enable non-engineers to ensure that drainage matters have been considered sufficiently
