Who we are

RAA was established in 1996 to deliver innovative solutions for the complex needs of customers of the urban drainage industry. As Consulting Engineers, we maintain a traditional family based approach to business, putting client needs first and resolving flooding problems in the urban environment using the latest hydraulic modelling and analytical techniques.

As a small consultancy we like to think we can be highly responsive and cost effective while at the same time offering a high quality specialised service. With offices in Sussex, the Midlands and the North West we operate nationally resolving flooding issues across the country.

Our Mission

Our mission is to resolve flooding problems in the urban environment using the latest analytical techniques.

Our Values

Our core values are fundamental to the way we operate and reflect the family principles that the company has been built on as well as a passion to maintain a leading edge in our field:

Our approach

We will discuss your requirements and tailor our work to your needs. We have a robust service model but can provide the flexibility to meet your objectives and regularly update our working methods to incorporate changing techniques and emerging trends.

InfoWorks ICM (integrated all-source catchment modelling) is our program of choice due to its superior power and detailed 1D-2D coupling capabilities. It offers exceptional results through its general versatility and functionality of the software and provides us with the ability to test future developments within the catchment through use of ‘scenarios’.

Our Quality Standards

RAA has a full ISOQAR accredited ISO 9001 and ISO 14001 Quality and Environmental Management System in place providing quality assurance and environmental responsibility as standard.   We are Cyber Essentials certified and currently working towards ISO 45001 Occupational Health and Safety and ISO 27001 Information Security.
