Excavation of Trenches and Road Cuts for installation of water mains Access to Homes and Public Places Limitation and disruption of access to homes, businesses and public places: - The trench excavations will create temporary difficulties of access to the adjacent buildings also on account of the traffic deviation and road cuts leading to some disturbance of the neighboring residents and users; - Impact on Businesses -Works will be effectuated on lots of limited length, in a way to minimize disturbance(Project Phasing Plan, planning); - Excavated areas and trench crossings shall be clearly marked and temporary fencing, bridges, access routes, signage, etc. shall be constructed to facilitate access and avoid accidental falls into these areas - Prior consultation and notification to the impacted and interested Implementation: Contractor Supervision: LWSC and external supervision team Information and consultation: citizens, hospitals, schools, institutions and local authorities Included in Contractor’s costs (Include cost of signs, media costs, printing, etc. Construction phases Air Emissions and Air Quality -Dust generated from earthworks. -Dust generated from materials handling. -Wind-generated dust from exposed areas of soil and mounds of stored soil. - Dust generated from vehicle movements emissions from construction traffic and machinery Impaired Air quality due to emissions form vehicles and dust generated - Respiratory impacts on site workers, nearby residents and pedestrian Dust masks and eye protection against dust, splinters, debris etc. (according to approved procedures) - Dust suppression methods such as wetting materials or slowing work should be employed as needed to avoid visible dust -Gas masks / respirators when working in closed areas such as access manholes, etc. (according to approved procedures) -Document requirements and standards in the Contractors Implementation: Contractor Supervision: LWSC and external supervision team Included in Contractor’s costs
Annex 2: ESMP Monitoring and Verification Arrangements Potential Environmental Impacts Specific Mitigation Measure/ Response or Description of Mitigation Measure Party Responsible for Mitigation Monitoring/Verification Method Cost/ Budget Party Responsible for Monitoring Monitoring Method Frequency ACTIVITY 1. Site Clearing/Preparation for Construction activities 1 1A-Site clearing and preparation may lead to and destruction of sensitive ecosystems and biodiversity loss 1B-Noise pollution and dust emission, causing health hazards and discomfort for communities 1A-1 Pipelines should be routed to avoid all sensitive ecosystems 1A-2 Vegetation clearance should be limited to only areas where construction is meant to be carried out 1A-3 Disturbed areas should be restored/revegetated after construction works 1A-4 Silt traps and other sediment control measures should put in place before clearing vegetation in areas where the potential for sedimentation exist. 1B-1 Construction equipment should be regularly serviced and kept in good working condition 1B-2 Ensure that equipment are shutdown when they are not in use 1B-3 Use appropriate dust suppression methods such as sprinkling in that are expected to handle vehicle traffic 1B-4 Plan construction activities to avoid or minimise disruption in sensitive community areas such as schools, health facilities, mosque, churches, etc, Construction Contractor Representative Visual inspection of construction sites and activities During site preparation and construction activities. ACTIVITY 2. Refurbishing existing networks and construction of new extension lines
2 2A-Noise pollution and dust emission 2A-1 See suggested mitigation measures above Construction Contractor Same as indicated above Representative Visual site inspection & inspection of records Daily during work 2B-Solid wastes generation and possible contamination of soil, surface and ground water from hazardous substances such as used oil fuel, cement waste, etc. 2B-1 Minimise waste generation and ensure that wastes are promptly collected and properly disposed of. Recycling and reuse of materials should be encouraged. 2B-2 Store hazardous wastes such as used oil and fuel in secure container 2B-3 Ensure that storage are bunded and provided with impervious surface 2B-4 Ensure that hazardous wastes are disposed of through certified waste service providers or at approved wastes disposal sites. 2B-4 Develop spill management plan Construction Contractor Representative Construction site inspection Regular site inspection
