Clean water and wastewater schemes that work in the real world.

MEG designs clean water and wastewater infrastructure for contractors, consultants, and asset owners across the UK. We do the right work upfront, developing practical, buildable designs with fewer surprises and redesign.

We’re hands-on experts. The people who design the job stay with it. From early investigation through design and into construction. It’s what makes us different.

Engineers on site

Our Specialisms

Clean Water

Capital maintenance, network, pumping and strategic mains schemes, from investigation and optioneering through to detailed design.

Wastewater

Sewer, storm and treatment-site civils, designed around how they will be built, operated and maintained.

Investigation

Desktop studies, surveys and proportionate site investigation — done early, before unknowns become problems on site.

Site Support

The engineer who designed the job stays involved through construction, carrying the design through to handover.

Emergency Rising Main Repair

George Leslie Ltd & scottish Water Saltcoats, Scotland Permanent Works Design 2026

The Job

Develop the permanent works for the emergency repair of an existing 700 mm rising main. MEG progressed the design from initial scope to construction issue in six weeks.

What we found

The permanent restraint couldn't be designed independently of the excavation. Poor pipe condition, deep excavation, tidal groundwater and sheet-pile removal all affected the conditions the permanent works would rely upon.

Saltcoats

The Call

Design around the construction sequence. MEG developed the large-diameter tie-ins and bespoke reinforced-concrete thrust restraint alongside the temporary works and overpumping strategy.

What didn't happen

No material redesign during construction. The permanent repair was constructed and backfilled without material changes to MEG's design.

  • 700mm Rising main
  • 6 weeks Scope to construction issue
  • 0 Material design changes during construction

AMP8 Water Mains Renewal Programme

M Group & United Utilities North West England Outline & Detailed Design 2026

The job

Provide outline and detailed design for approximately 60 km of water mains renewal across North West England.

What we found

At programme scale, designing every scheme from scratch wastes effort. Treating every site as the same creates a different problem.

The call

Standardise what can be standardised. Engineer the exceptions. Repeatable solutions are used where conditions allow, with investigation and engineering effort focused on scheme-specific risks. Trenchless renewal is considered before open-cut where appropriate.

What didn't happen

Lessons weren't left on individual schemes. Learning from each design was fed back into standard details and design processes for subsequent schemes.

  • ~60km Water mains renewal programme
  • Trenchless-first Renewal optioneering
  • Repeatable by design Standardised solutions at programme scale

Cowdenbeath LTS Process Equipment Integration

Processplus & scottish Water Horizons Cowdenbeath, Scotland Civil & Structural Design 2026

The job

Design the permanent civil and structural works for new process equipment at an operational liquid transfer station.

What we found

The equipment base couldn't be designed in isolation. Existing levels, services, tanker movements and pedestrian access all affected the completed installation.

The call

Treat the installation as one piece of civil engineering. MEG integrated the structural base with levels, kerbing, ducting, access, tanker segregation and handrail design.

What didn't happen

The surrounding civils weren't left to be worked out on site. Access, segregation, levels and services were resolved as part of the permanent design.

  • Integrated civils Structure, access, segregation and services
  • Design & site support Detailed design through construction
