- Subsurface Storage Pros Multifunctional use of the area large
space available land requirements are minimal Advantages for water
quality Constant temperature, absence of sunlight heating and
evaporation losses No mosquitoes or algal bloom Potential
bacteriological purification and equalisation of the water quality
