Winter Groundwater Monitoring


As built developments can lead to an increase in surface water run-off - contributing to flooding and surface/groundwater pollution - it is frequently recommended that all relevant planning applications are supported with groundwater and drainage assessments (National Planning Practice Framework Guidance – NPPF; Surface Water and Drainage Supplementary Planning Document – SPD; and Water Framework Directive – WFD). Thorough assessment and drainage solutions should aim to not exacerbate existing problems.

Adequate drainage design (SuDs, soakaways etc.) will often require groundwater monitoring (or groundwater survey) data to determine the depth of the water table. Winter groundwater monitoring is undertaken during the months of October to March targeting the highest water table, in support of drainage design.

Constructive Evaluation Ltd operate throughout East and West Sussex, Hampshire and Surrey, working closely with Local Authorities including Chichester District Council and Arun District Council. We are able utilise several monitoring techniques including manual data readings and more bespoke long-term level loggers, to suit the requirements of the site. In addition to monitoring, we are able to undertake infiltration/percolation tests for soakage structures, in accordance with BRE 365.

CE also offer a range of comprehensive services, including Ground Investigation, Site Investigations, Materials Testing and Building Surveying.

Please get in touch if you wish to discuss any of these matters further. Happy New Year!
