13A. Design and Location of the Proposed Components50. STP. Land acquisition is not required. The design included a minimum 100-m bufferzone from any habitation. The work will not encroach into forest, and the construction materialwill not be stored on forest lands. No trees or vegetation will be required to beremoved/disturbed. The site is approachable by access road.51. Sewerage Network. Land acquisition is not required. The subproject sites are located inexisting right of ways (RoWs) and government-owned land. There are no protected areas,wetlands, mangroves, or estuaries in or near the subproject location. Trees, vegetation (mostlyshrubs and grasses), and animals are those which are commonly found in urban areas.The components will support small, non-invasive interventions. Traffic management will benecessary during sewerage network pipe-laying on busy roads.52. Screening of environmental impacts has been based on the impact magnitude(negligible/moderate/severe – in the order of increasing degree) and impact duration(temporary/permanent). Table 4 shows the screening of impacts; N/T represents the lowestimpact while S/P represents the highest impact. Numerator represents the Degree of Impactand denominator represents the duration of impact.Table 4: Screening of ImpactsDuration of Impact Magnitude (Degree of Impact)Negligible(N) Moderate(M) Severe(S)Temporary(T) N/T M/T S/TPermanent (P) N/P M/P S/P53. In case of sewerage components, no significant impacts are anticipated since the layingof sewer line will be along the already built up area and there are no environmentally sensitiveareas along the alignment.54. The STP location is close to residential colony and even with provision for developmentof a buffer zone along the site boundary, impacts on existing environment or surroundings maybe anticipated. The proposed pipeline is not passing through any environmentally sensitiveareas.55. The following table provides the potential environmental impacts due to the subproject.Table 5: Anticipated Environmental Impacts of Davangere Sewerage SubprojectImpact DescriptionLocation impactsContamination of groundwater resources due to leachingof aerated lagoon.Significance of the ImpactN/P – This is not be significant as the groundwater tableis deep at around 40 to 50 ft.Loss of amenity and odor nuisance to neighbors due toproposed STP.Design ImpactsDischarge of partially treated sewage will have potentialto pollute the agricultural fields.Nuisance due to leakage / overflowing of sewers.Nuisance due to mosquito breeding and bad odours fromM/P – Residential areas are located at in close proximityto the site. The STP layout will include a minimum of100-m buffer zone around the siteN/P – The treated sewage may be used for irrigation.Treatment will be designed to meet inland surface waterdischarge standards which are more stringent thanirrigation standards.N/P – Prevented by the sewerage network improvementM/P – Residential areas are located at in close proximity
