Ecological AspectsPotential Impact (Consequence)Consequence severity rankingImpact likelihood ratingRisk ratingFloraMinor impact to flora including the threatened species may occur during the installation of water transmission pipeline. Construction of water treatment plant may displace or remove aquatic floralMinorPossibleLowspecies including the threatened species and ECA. Removal of flora due to soil/trench excavation (for pipeline installation) may be replaced by plantation programme; hence no major effects are expected.FaunaMinor impacts (temporary displacement) to all types of fauna including the threatened species and species along ECAs may occur during installation of water transmission pipeline. Soil/trench excavation and construction of WTP have negative impacts (e.g., habitat loss). Temporary loss of habitat of threatened species (i.e. Ganges River Dolphins, threatened lizard, and reptile as well as bird species subject to extinction) may occur during construction activities due to sensitivity of the species to change in the habitat. These changes are anticipated to be temporary and number of specific measures will be taken to reduce these impacts. Therefore, no major or long-term effects are anticipated, except loss of some habitat.MinorPossibleModerateFishFish communities including the threatened species could potentially be impacted from soil deposition in aquatic habitat, fish pass, noise, water pollution, etc. The majority of impacts would be temporary in nature; fish may avoid the impacted areas during construction period but return when it ceases.LowPossibleLow
