Nationwide Drainage Mapping & Infrastructure Improvement Programme for Major Retail Distribution Network

Overview

A leading UK retailer engaged us to undertake a comprehensive drainage asset mapping and condition review programme across its national distribution centre portfolio.

The client required greater visibility of its drainage infrastructure, improved understanding of environmental risks, and a clear roadmap for maintaining compliance while reducing operational disruption across its sites.

Through a detailed survey and inspection programme, we delivered fully mapped drainage networks, identified critical risks and asset condition issues, and developed a prioritised improvement strategy. This work has since evolved into a long-term Planned Preventative Maintenance (PPM) programme, helping the client protect its infrastructure, improve operational resilience, and minimise environmental risk.

The Challenge

Like many large industrial and distribution facilities, the client’s sites had evolved over many years, resulting in incomplete records and limited visibility of below-ground assets.

This created several challenges:

  • Unclear drainage network layouts
  • Difficulty identifying pollution and environmental risks
  • Limited understanding of asset condition and integrity
  • Increased reactive maintenance costs
  • Potential compliance concerns relating to interceptors, fuel infrastructure, and wastewater systems
  • Delayed fault diagnosis during emergency call-outs

The client wanted a trusted partner capable of providing both technical insight and practical improvement recommendations.

Our Approach

We undertook a comprehensive drainage infrastructure review across multiple distribution centres.

Our programme included:

Drainage Asset Mapping

  • Detailed surveys of all drainage assets
  • Identification and tracing of drainage networks
  • Creation of accurate drainage schematics and site plans
  • Clear visual representation of system connectivity and flow paths
  • Identification of high-risk and critical infrastructure assets

Risk & Condition Assessments

Our engineers assessed:

  • Drainage system condition
  • Asset accessibility
  • Pollution prevention measures
  • Potential points of environmental risk
  • Areas vulnerable to blockages or system failures
  • Compliance-related concerns

The findings were compiled into detailed reports providing actionable recommendations and prioritised remedial works.

Delivering Long-Term Improvement

Following completion of the mapping and review programme, we worked collaboratively with the client to implement a stabilisation and maintenance phase designed to address historical dilapidations and prepare sites for structured preventative maintenance.

The programme includes:

Planned Preventative Maintenance (PPM)

  • Routine drainage inspections
  • Scheduled cleaning and maintenance
  • Defect monitoring and reporting

Interceptor Management

  • Full interceptor servicing
  • Five-year integrity testing
  • Pollution prevention assessments
  • Compliance support

Specialist Asset Maintenance

  • Vehicle wash interceptor servicing
  • Pump station inspections
  • Urinal descaling programmes
  • Asset condition monitoring

These measures are helping to improve system performance, reduce environmental exposure, and establish a reliable maintenance baseline before sites transition into ongoing annual PPM programmes.

Additional Support & Added Value

As part of our consultative approach, we have also:

  • Conducted complimentary fuel infrastructure assessments
  • Identified opportunities to reduce environmental risk
  • Assisted with planning future fuel tank maintenance activities
  • Developed proposals for underground and overground fuel tank cleaning programmes

By taking a broader view of the client’s infrastructure, we have been able to identify opportunities that extend beyond drainage maintenance alone.

Results

Improved Visibility

The client now has a clear and accurate understanding of how drainage systems operate across its distribution network.

Reduced Risk

Potential environmental and operational risks have been identified and prioritised before they develop into costly failures.

Better Decision Making

Accurate asset information allows the client’s facilities teams to make informed investment and maintenance decisions.

Enhanced Compliance

A structured maintenance approach is helping support environmental compliance and asset integrity obligations.

Stronger Operational Resilience

Proactive maintenance is replacing reactive firefighting, reducing disruption and improving asset reliability.

Client Feedback

The client has praised:

  • The quality and depth of insight provided through the drainage mapping programme
  • Our proactive and consultative approach
  • The professionalism and thoroughness of our engineers
  • Our focus on identifying root causes rather than simply resolving symptoms
  • The practical recommendations delivered to improve long-term asset performance

Why It Matters

Effective drainage management is about more than responding to blockages and emergencies. By understanding infrastructure, identifying risks early, and implementing targeted maintenance strategies, organisations can extend asset life, improve compliance, reduce environmental exposure, and lower overall maintenance costs.

This project demonstrates how detailed asset intelligence combined with proactive maintenance planning can transform the management of critical drainage infrastructure across a large property portfolio.

Marketing Summary (Short Version)

Helping a Major UK Retailer Take Control of Its Drainage Infrastructure

We partnered with a leading UK retailer to map and assess drainage networks across its national distribution centres. Through detailed asset surveys, risk assessments and drainage mapping, we provided complete visibility of their infrastructure and identified key areas requiring improvement.

The programme has since expanded into a comprehensive maintenance strategy including interceptor servicing, integrity testing, pump station inspections and wider environmental risk management activities.

The result is improved compliance, reduced operational risk, enhanced asset performance and a long-term preventative maintenance framework that supports business continuity across the client’s estate.

Key Services Delivered:

  • Drainage Mapping
  • Asset Verification
  • CCTV Surveys
  • Interceptor Servicing
  • Five-Year Integrity Testing
  • Pump Station Inspections
  • Urinal Descaling
  • Planned Preventative Maintenance
  • Fuel Infrastructure Assessments
  • Environmental Risk Reduction

This approach has earned strong client praise for its proactive delivery, technical expertise and focus on solving root causes rather than simply treating symptoms.
