The design and construction of a wetland site requires a number of different surveys and investigations, including (but not limited to) ecological appraisals, ground water risk assessments, topographic surveys and phosphate monitoring. The surveys are essential to determine the suitability of the site and to properly inform the preliminary and detailed design process.

Professional services are also required for the next stage of the proposed works in order to progress detailed design and to gain planning approval for the wetland sites.
