Who We Support
DDR Engineering can work alongside:
Engineering Consultancies
Additional specialist capability when internal teams are stretched or particular expertise is required.
Contractors & Design-and-Build Teams
Mechanical engineering and technical support during design development and project delivery.
Utilities & Asset Owners
Independent engineering review, technical advice and specialist assessment.
Equipment Suppliers & Technology Providers
Engineering support relating to equipment integration, specifications, system interfaces and project requirements.
Smaller Engineering Practices
Access to senior water and wastewater mechanical expertise without maintaining that capability permanently in-house.
