Richard Allitt Associates Ltd
Richard Allitt Associates Ltd has been providing expert urban drainage solutions nationally since it was founded in 1996. With headquarters in Sussex, the company expanded with a regional office in Altrincham in 2019 to better serve a growing number of clients in the North West.
Offering specialist hydraulic modelling services, RAA has established itself as a leader in integrated catchment modelling and has recently been appointed by CIWEM and the Environment Agency to lead the update of the industry guidance on Integrated Urban Drainage. Our client base is broad and includes water companies, government agencies, Lead Local Flood Authorities, as well as the private sector. We have strong links with academia and undertake many Research and Development Projects. We also act for many clients on expert witness cases.
RAA has been a full Partner of Susdrain since its inception and proudly sits on the project steering group alongside many Tier 1 consultants. This investment is being driven more from a desire and passion to see real progress in the adoption of SuDS rather than the PR benefits for the company.
Richard Allitt Associates has made considerable investment in computer hardware, industry leading software and the training of hydraulic modellers. We are able to model all possible flooding mechanisms in urban areas, enabling engineers to fully understand how flooding occurs and then devise suitable mitigation measures which frequently include retro-fitting SuDS.
For organisations that need high quality urban drainage advice, Richard Allitt Associates has the breadth and depth of knowledge and technical expertise to help.
