Drainage Design

Using specialist software, EDS can undertake storm and foul drainage designs from concept through to construction and adoption by NI Water and to the relevant British Standards.

SUDS/Attenuation Design

With most developments required to limit discharge from the proposed site, EDS can develop both masterplanned and detailed design of both soft landscaped and hard engineered systems in accordance with adoptable standards and the SuDS Manual (CIRIA C753).

DfI Rivers Applications

EDS is familiar with the application processes (Schedule 6) and can develop application packages for various consents when working on or near a watercourse. These may include storm discharge applications, applications to divert/culvert a watercourse or any other works required.

Hydraulic modelling

To identify flood risk to existing or proposed development sites, EDS can develop bespoke flood models through calculation of peak hydrological data and procurement of river topographic data. Using specialist software, EDS can determine flood levels in rivers and develop detailed reservoir inundation models for determination of depths and velocities, as sometimes required for planning applications.

NI Water applications

EDS is familiar with the application processes required by NI Water from development planning to full adoption of constructed networks. EDS recommends early submissions of a PDE (Pre Development Enquiry) to identify any NI Water constraints.

Hydrological Assessments

Hydrology is the study of the processes of the water cycle such as evaporation, evapotranspiration, rainfall, runoff, infiltration and storage of water.
