Water services

We have a team of specialists with expertise in all aspects of water resource management, water quality, hydrogeology and hydrology and offer a range of services including

Regulatory assessments, permissions and permits

We undertake Water Framework Directive (WFD), Habitat Regulation Assessments (HRA), land drainage and flood defence consent applications for construction projects, maintenance and capital dredge campaigns in line with EA guidelines, as well supporting water abstraction and discharge environmental permit applications and ongoing monitoring and compliance audits. Our broad and experienced understanding of the water environment means we are very well placed to support environmental impact assessments (EIA) and planning applications that require surface, ground and/or marine water assessments.

Groundwater and surface water monitoring

Ensuring that the investment in a monitoring programme is both justified and robust is critical, and that the sampling design is targeted correctly to deliver accurate data. The investment in collecting adequate and accurate data is often undervalued, yet decisions many magnitudes more expensive are made on whatever data is collected. Our team, can design, evaluate and advise on sampling programmes and strategies, and carry out the data collection programmes required to make sound and robust business decisions. We are able to measure water levels, flows, and quality in groundwater, springs, rivers, canals, ponds, lakes and reservoirs for a wide variety of chemicals, algae and phytoplankton.


Water is one of our most precious natural resources. Without it, there would be no life on earth. Hydrology has evolved as a science in response to the need to understand the complex water system of the earth and help solve water problems. Although it is plentiful, water is not always in the right place at the right time or of the right quality. An overall aim of hydrologists is to apply scientific knowledge and mathematical principles to mitigate water-related problems in society and environmental protection. This may mean working out the best use of water supplies for cities or for irrigation, controlling river flooding or soil erosion, protecting or cleaning up pollution, and planning long-term water storage reservoirs, flood risk assessment and flood or drought warnings. Our specialists carry out investigations and modelling, supporting infrastructure developments and regulators and have worked on a variety of projects, including international work such as large-scale wetland restoration works at Al Ha’ir Lakes in Saudi Arabia.


Our team can assess and complete groundwater protection and vulnerability assessments, undertake intrusive investigations to determine site specific conditions and put these in a local, semi-regional and regional context. Therefore, our team are experienced in evaluating the flow characteristics, quantity and quality of groundwater by interpreting data, completing investigations and sampling, and using modelling techniques. We have a specialist expertise in understanding groundwater and surface water interactions that support wetland fen areas and the ecology that is reliant on these ephemeral water environments.

Sewage discharges and SuDS

With an ever ageing foul sewerage network and increasing population growth the pressure on new development to deliver Sustainable Drainage System (SuDS) solutions is immense. We can solve these problems through our understanding of water quality loads in natural systems, advising on the type and variety of alternative treatment processes that are available. With our sister company, Thomson Habitats, and our in-house team of ecologists and landscape architects, we can design and physically create SuDS and wetlands, including earthworks and excavations, pond lining, filling, planting, and installation of features including paths and viewing platforms, to truly deliver sustainable solutions with both long and short term benefits.

Catchment services

The management of catchments whether for water quality improvement or flood defence reasons continues to grow rapidly, our approach is to ensure that any such programmes maximise outcomes. We are able to design and execute monitoring programmes and feasibility studies at both local and catchment-wide scale, as well as assessing loads and sources of contaminants from basic nutrients through to pesticides and more exotic contaminants, the threat from both terrestrial and aquatic invasive species, and the fate and transport of new and unexpected pollutants.

Geospatial mapping and data management

Managing large data sets, whether collected ourselves on a clients’ behalf using traditional methods, or using our licenced Unmanned Aerial Vehicle (UAV, is important, as it presents the results from large data sets in easily digestible forms. We pride ourselves in being able to manage, interrogate and analysis large data sets, draw conclusions and present these in easily understandable formats.

Expert services

With our range of experts we are able to support in legal disputes and inquiries, particularly relating to contamination and environmental regulation.
