CRM has considerable expertise is designing underground drainage systems to BSEN752 (2008) including a full evaluation and design of SUDS solutions to meet modern sustainable design standards. We work for a number of the North West's leading structural engineering practices and some architects, acting as sub consultants operating as a stand alone organisation, or as a virtual design office within a larger consultancy. CRM can offer a service stretching from simple pipe sizing checks, up to full design and detailing service.

We have experience of design with infiltration techniques, attenuation, foul drainage, on-site foul disposal, pumped drainage, suspended drainage in basements and liaison/application to Water Utilities.

Whatever your drainage needs, CRM can tailor a service to suit

In addition to desk based design work, CRM offer a survey service, where we supervise a CCTV survey, collect invert and cover level data, and perform calculation checks on the system. By having qualified Engineers supervising survey works, it can be guaranteed that all the data is collected first time, often saving time and costly re-visits.
