Environmental impact assessment for the proposed MWSC customer service building development project

Abstract

This report discusses the findings of an Environmental Impact Assessment (EIA) carried out for the proposed 10-storey customer service building of Male’ Water and Sewerage Company (MWSC). The project is proposed by the MWSC, the contract for construction phase has been awarded to Amin Construction. This project requires EIA as the building has a basement, under EIA regulations 2012 buildings with basement require EIA clearance. The main objective of the EIA is to identify potential impacts of excavation, construction of foundation and dewatering and consider mitigation measures that can be adopted. In addition, the EIA would also consider other construction phase and operational phase activities such as waste management, energy and water supply although they are not directly related to the scope of the EIA. The project is to commence as soon as the EIA is approved and the duration of the project is estimated to be completed by December 2017. Substructure works, which is considered to be the most sensitive component (socially and environmentally), is expected to be completed within two months. The critical elements of excavation and dewatering are expected to be completed within 80 days. Therefore, the project has a critical impact timeframe of less than 4 months. Currently MWSC does not have dedicated customer service centre, where all services can be attained from one stop. The proposed project ensures such a service base to the customers are provided, thus meeting this existing need of the company. This improved service also means that additional jobs will be created thus contributing positively to the economy. Looking at the existing environment of the site, the site is devoid of any significant flora or fauna. The traffic is considerably high in Ameenee Magu during peak office and school hours and majority of the structures within close radius of the site is structurally sound. The groundwater quality is not very saline when compared to some other parts of Male’. Almost all of the negative impacts envisioned for the project occurs during construction phase and as highlighted previously most of these impacts are associated with substructure works. However, almost all these impacts are minor and can be reduced to negligible levels with the mitigation measures proposed in this report. In this regard, the potential negative impacts associated with this project can be summarised as impacts related to groundwater quality and quantity, impacts on nearby buildings in terms of structural damage, impacts on air quality, impact on ambient noise, impacts on utility services, impacts on traffic and impacts on health and safety. Mitigation measures proposed for the project like minimizing dewatering to the shortest possible time, ensuring proper storage and transport of construction material and waste, restricting noisy activities to day time, undertaking works by experienced operators and supervisors, avoiding closure of roads during peak rush hours and implementing international best practice health and safety standards will help to reduce the influence of most of the envisioned impacts to negligible levels. The EIA report proposes a monitoring program that will help to identify the actual impacts and to identify the effectiveness of the implemented mitigation measures. In this regard monitoring will include, monitoring of groundwater quality, monitoring of dust and noise, visual assessment of nearby buildings and monitoring of traffic condition. The monitoring reports will be submitted to EPA every two months during construction phase and once thereafter to meet the requirements of the EIA regulations. The reports will be submitted in the format specified in the EIA regulations. Overall, this project is a positive project and the negative impacts envisioned are only for the construction phase and all these impacts can be easily mitigated.
