Asset Management

The supply of clean water and safe sewage treatment carries critical security responsibilities and is regulated by the Government. We help companies meet their obligations under the SEMD Direction (1998), by delivering tailored asset protection plans to safeguard infrastructure and maintain service continuity.

Total Loss Contingency Plans

We develop Total Loss Contingency Plans that help water companies maintain supply during partial or total treatment works failure.

These strategic documents support company response plans, include clear operational guidance and form part of an Acceptable Level of Response Plan. Our plans have been reviewed and commended in SEMD audits.

Asset Security

We help organisations protect critical assets by identifying risks and strengthening security measures. Using client data, site surveys, and interviews with key personnel, our team delivers practical, risk‑based analysis that ensures improvements are both effective and cost‑efficient.

Our approach supports compliance with the economic regulator of the water sector in England and Wales (OFWAT) and SEMD requirements, giving water companies confidence that their security arrangements meet regulatory expectations while remaining sustainable and affordable.

Risk Assessment

Evaluating asset categories and potential threats to determine the right level of protection.

Data & Surveys

Using client information, site inspections, and staff input to build a clear security picture.

Regulatory Compliance

Supporting organisations in meeting OFWAT and SEMD requirements with tailored solutions.

Cost-Effective improvements

Delivering practical recommendations that strengthen security while reducing unnecessary capital spend.

Flood Risk to Assets

We deliver Flood Risk Assessment and protection solutions tailored to the needs of utilities and infrastructure operators. With extensive experience across the water, gas, and electricity sectors, we help organisations understand vulnerabilities and strengthen resilience against flooding.

Our expertise ensures compliance with required standards while providing practical, sector‑tested strategies that safeguard critical assets and maintain operational continuity in the face of flood risk. Our assessments include:

Catchment Hydrology & Reservoir Flow

We analyse catchment run‑off patterns and reservoir discharge to understand how assets may be exposed to upstream or localised flooding events.

Climate change integration

Future climate impacts are factored into our assessments, going beyond Environment Agency flood maps to provide a more realistic picture of long‑term risks.

Hydraulic modelling

Using advanced modelling techniques, we evaluate river, coastal, and other flood sources to quantify potential exposure and identify vulnerabilities across different scenarios.

Protection & Resilience Solutions

We advise on a range of measures, from engineered flood defences and routing strategies to passive and active asset protection, ensuring resilience is built into every scheme.

Frequently Asked Questions

Which Lead Local Flood Authorities have you worked with?

With over 20 years’ experience, we’ve partnered with Lead Local Flood Authorities (LLFAs) across the UK to secure funding, investigate flood events, develop drainage strategies, and reduce flood risk under the Flood and Water Management Act 2010.

Our experience includes work with Denbighshire County Council, Flintshire County Council, St. Helens Council, Cheshire Council, Gwynedd Council and Derbyshire Council.

Which water companies have you worked with?

We’ve partnered with Welsh Water since 1998, delivering water-main renewals, drainage design, and wastewater treatment projects. Our experience also includes work with Severn Trent, Thames Water, and United Utilities, alongside Tier 1 and 2 contractors across the UK.

Where have you previously supported-asset management and critical infrastructure?

We work with asset managers and operators across water, power, and transport sectors, helping public and private clients maximise asset value. Our experience includes projects with Highways England, National Trust, Northern Powergrid, Welsh Water, Western Power Distribution, Keele University, and Public Health England.

What is a Flood Risk Activity Permit and why do I need one?

A Flood Risk Activity Permit is a legal requirement for works on or near main rivers, flood defences, culverts, floodplains, or sea defences. Introduced in 2016 under the Environmental Permitting (England & Wales) Regulations, it ensures that proposed activities do not increase flood risk, impact drainage, or harm the environment.

Why is hydraulic modelling important?

Hydraulic and hydrological modelling provides vital insights into the behaviour of watercourses and networks. We use these tools to help clients implement sustainable water management solutions, enhance asset performance and establish resilient strategies to respond effectively to operational challenges and emergencies.
