Wessex Reservoir Management
Wessex Water commissioned APEM to investigate water quality problems in several reservoirs and gravel pits. Nuisance algal blooms and manganese release were causing costly problems in the treatment process and we needed to investigate in-reservoir solutions. Before these could be considered, accurate bathymetric data were required to establish resource volumes and sediment profiles. Nutrient pathways were investigated using historic nutrient data to assess external and internal (sediment & birds) nutrient sources which fuel the algal blooms and contribute to sediment-water interface anoxia.
