The project aims to provide efficient and sustainable service to ensure environmental and social stability in accordance to the Five Year Development Plan, the Millennium Development Goals and Poverty Reduction Strategy. The total cost of the project is approximately (US$lSO) million of which the approved credit amount by the International Development Agency (IDA) -for phase (1)- is approximately (US$130) million and the committed amount by the Government of Yemen (GoY) is (US$20) million. Urban Water Supply and Sanitation Project has included Environmental Impact Assessment (EIA), along with Environmental Management Plan (EMP) and Mitigation Program for civil works contracts signed by the project One of the overall objectives of the Environmental Management Plan (EMP) and Mitigation Program is to ensure the possibility of correcting the planed measures to mitigate adverse impacts. Many of these impacts have been foreseen, but the degree of each impact may differ from the one expected. This report summarizes the implementation progress of the Environmental Management Plan and Mitigation Program for civil works contracts in Sana'a governorate for months August - September 2007. The report was prepared by Environmental and Safety Officer (ESO) based on monthly progress reports of consulting companies supervising civil works, meetings held with consulting firms, contractors, public and field visits to construction sites. 1 Republic of Yemen Ministry Of Water and Environment Urban Water Supply and Sanitation Project CHAPTRER ONE ENVIRONMENTAL MONITORING REPORT FOR CONTRACT NO: SANCS-2 AUGUST - SEPTEMBER 2007 2 1.1 Project Description -PI'oject name: Construction ofReseIVoirs in Sana'a (AI-Nahdain area). -Contract NO: SANCS-2 -Name of the contractor: Abdul Aziz AI-Tam Corporation for Trading & Contractor -Name of the consulting firm: Ahmed Abdel Wareth Consulting Engineers -Location: Sana'a city -Contl'act description & performance Due to the changing of the reseIVoir site, there has been a delay in the contract construction work.

I 4 1.2 Governmental Coordination & Consultation As the construction works in this contract has only started for the reservoir and pump station and the land belongs to a military camp, the coordination has been made mainly with the Ministry of Defence that owns the land. Continuous coordination is taking place with the Water Supply and Sanitation Authority. On the other hand, coordination has already started with some authorities before the commencement of the construction of the main pipeline. These authorities are Water Supply and Sanitation Local Corporation, General Traffic Management, General Electricity Authority, General Telecommunication Authority 1.3 Public Consultation As the area -where the reservolf IS being constructed- IS not inhibited, no Public consultation was performed. 1.4 Environmental Mitigation Measures As identified in the EIA study, the project may cause some negative impact to the environment. Therefore, some measures were put to mitigate these impacts. Potential negative impacts, mitigation measures, implementation responsibility and situation are summarized in table 1.2. 5 Table 1.2: Potential Impacts and Mitigation Measures Item Potential Negative Mitigation Measures Implementation Implementation Impact Responsibility Situation ----- Sewage from destroyed Improper disposal of Controlled transport to WWTP, truck emptying at Contractor, to be at Not applicable cesspit and households sewage during WWTP dunng non-peak hours.

No major areas of non-compliance with the Environmental Management Plan were identified during the filed visit. 1.6 Recommendations 1- Although no inhabitants or public building exist In the area and access is permitted only to people working on the site, it is recommended that safety measures are applied by insuring the provision of warning tapes and sings in the sites, especially during nighttimes as some soldiers may come across the construction site. 2- The contractor should quite understand the importance of the environmental mitigation measurements and the meanings of the EMP implementation. 9 1.7 Photographs Upper photo: The reservoir under construction in uninhabited area Rernainings of the warnings tapes 10 Republic of Yemen Ministry Of Water and Environment· Urban Water Supply and Sanitation Project CHAPTER TWO ENVIRONMENTAL MONITORING REPORT FOR CONTRACT NO: SANCW-2 AUGUST - SEPTEMBER 2007 11 2.1 Project Description -Project name: Sana'a Water Distribution System Improvements (Low Level Distribution Zone: Akama and Sabeen) -Contract NO: SANCW-2 -Name ofthe contracto.-: Water Resources & Development Co. -Name ofthe consulting firm: HARZA Engineering Company International in Association with Montgomery Watson Arabtech Jardaneh -Location: Sana'a city - Contract description & performance This contract covers an area of 230 ha.

However, no large-scale public consultation was performed. 2.4 Environmental Mitigation Measures As identified in the EIA study, the project may cause some negative impact to the environment. Therefore, some measures were put to mitigate these impacts. Potential negative impacts, mitigation measures, implementation responsibility and situation are summarized in table 2.2. 14 Table 2.2: Potential Impacts and Mitigation Measures -~~~ ---------- ----------- Item Potential Negative Impact Mitiga tion Measures Implementation Implementation Responsibility Situation ---------- ---------- Sewage from destroyed Improper disposal of sewage Controlled transport to WWTP, truck emptying at Contractor, to be at Not applicable cesspit and households during construction.

Some tapes were recently placed in the site. Such trenches were noticed in main roads which disturb the traffic and form a hazard to pedestrians especially during night hours. 2. ESO field visit for this contract were conducted after fmishing most of the construction work. So it should be mentioned that this report is based mainly on observations made for the very limited remaining construction sites. 3. No major areas of non-compliance with the Environmental Management Plan were identified during the filed visit. 2.6 Recommendations 1. Although incidences of removing warnmg tapes occurred, more attention should be given to the safety issues by insuring the provision ofwaming tapes and sings in the remaining construction sites, especially in construction sites on the main roads and during nighttimes. 19 2.7 Photographs Construction site in the heavily populated area of Bah AI-Yemen where only warning tapes are used 20 Republic of Yemen Ministry Of Water and Environment Urban Water Supply and Sanitation Project CHAPTRER THREE ENVIRONMENTAL MONITORING REPORT FOR CONTRACT NO: SANCW-3 AUGUST - SEPTEMBER 2007 21 3.1 Project Description -Project name: Sana'a Water Distribution System Improvements (Low Level Distribution Zone: AI-Jiraf and Hasabah West). -Contract NO: SANCW3 -Name of the contractor: AI-Rehab Engineering Agencies & General Contracting Company - Name of the consulting firm: HARZAEngineering Company International in Association with Montgomery Watson Arabtech Jardaneh - Location: Sana'a City - Contract description & performance This contract covers an area of 302 ha, the site is located at AI-Jiraf and Hasabah West areas of Sana' a, includes the installation of items shown in table 3.1.

It was noticed that the some of the open trenches were without safety sings and tapes. These trenches are located near schools which for a hazard to children. When asking about the missing warning sings and tapes, it was mentioned that these tapes are always removed by children or pedestrians. 2. When visiting the very limited number of construction sites, it was noticed that some of the construction remainings were in place without warning signs and tapes. In addition to forming a potential hazard to pedestrians, these remainings form also a dumping site for other remainings that are brought from construction works in private properties which increase the hazard and also the coast and time of removing them. 4.6 Recommendations 1. More attention should be given to the safety issues by insuring the provision of warning tapes and sings in the remaining construction sites, especially in construction sites on the main roads, near schools. 2. It is highly recommended that remainings of the construction works are removed from construction sites right after finishing the work to avoid the unwanted consequences of the late removal of these remainings. 3. The contractor should quite understand the importance of the environmental mitigation measurements and the meanings of the EMP implementation. 39 4.7 Photographs Remaining of the construction works where some other construction remainings are added from private properties 40
