PROPOSAL SUBMISSION PLACE: U.S. Trade and Development Agency, 1000 Wilson Blvd., Suite 1600, Arlington, VA 22209, Phone: (703) 875-4357, Fax: (703) 875-4009. The Grantee invites submission of qualifications and proposal data (collectively referred to as the "Proposal") from interested U.S. firms which are qualified on the basis of experience and capability to develop a feasibility study for on a wastewater collection, disposal, and treatment project for the city of Taiz, Yemen. Yemen, one of the poorest countries in the Arab world, faces a high population growth rate and scarce water resources. The demand for fresh water in the country is expected to exceed water resources capacity within the next few decades and a substantive water supply deficit is expected to occur within the next two decades. These problems are exacerbated in Taiz, the country?s third largest city and one of the fastest growing, which receives an average of only 21 inches of rainfall per year. According to data from the Yemeni Ministry of Planning and Development, the city?s population will increase from 446,874 in 2000 to 1,033,172 in 2020. Current water supply sources for the City of Taiz are water wells, which produce an average of 17,000 m3/day (4.49 million gallons/day). Available water supply sources cannot meet existing water demand. Water supply shortages lead to the utilization of wastewater for irrigation. In addition, groundwater from the water wells exhibits high nitrate content and does not meet the World Health Organization drinking water standard. Nitrate contamination of groundwater generally occurs as a result of the infiltration of wastewater and fertilizers. The existing wastewater facility in Taiz was installed in the 1970?s and consists of rudimentary primary treatment and a set of two anaerobic lagoons followed by a facultative and a maturation pond. The lagoons provide secondary treatment but the effluent does not meet secondary treatment standards. The pretreatment of the water, involving the disposal of screenings, grit, and sludge is currently uncontrolled, creating insect proliferation. Leakage of wastewater drainage into the surrounding topsoil occurs on a regular basis. The lagoon pools are not fenced and local farmers illegally pump wastewater from the treatment pools to use for irrigation purposes. The effluent does not meet water quality standards for irrigation, therefore its use bears a public health risk. In addition, the effluent contains a high concentration of dissolved solids and there is a high potential for increasing soluble salts content in the irrigated soil, which leads to soil salinity and economic losses due to low agriculture productivity. The wastewater treatment plant in Taiz underwent a minor expansion in the mid-1980s. The system covers approximately thirteen percent of the city?s area with forty percent of the city?s population connected. The existing wastewater collection system is operated as a gravity system with no pumping stations. Four trunk mainlines meet at a central location, where wastewater flows to the lagoons of the wastewater treatment plant. Long flow time in the system generates high levels of sulfate gas, resulting in corrosion of the pipe material. Many of the large industrial outfits in Taiz operate their own wastewater management system and industrial wastewater is often discharged in open ditches and/or to groundwater. The Government of Yemen commissioned an independent study to assess the deteriorating wastewater treatment situation in Taiz. In December 2001, the consulting firm Dorsch Consult prepared a report for the Yemeni Ministry of Electricity and Water, entitled ?Taiz Water Supply and Sanitation Project.? This study, also known as the Initial Development Plan, provides a description of the existing water and wastewater facilities in the city and analyzes two scenarios for the expansion of the wastewater management system. The main difference between the two scenarios investigated is that Scenario 1 would provide sewerage for 100% of Taiz and Scenario 2 would increase coverage to only 75%. In both cases the planned coverage would be achieved by the year 2010. The Initial Development Plan laid the conceptual foundation for the Taiz Wastewater System project and the Feasibility Study will assess which scenario is most appropriate for the City of Taiz. The proposed project would rehabilitate and install a new wastewater collection, disposal and treatment system for the city of Taiz. The Feasibility Study would include the preliminary detailed engineering design and preparation of tender documents for the project. The study will achieve an overall analysis of present water supply and sanitation conditions while also taking into account future requirement expectations. The study will ensure that the facilities to be provided are efficient cost solutions, technically feasible, and financially and environmentally sustainable. In addition, the most feasible alternatives for effluent reuse, sludge treatment and use and odor control for wastewater will be determined by the Feasibility Study. The study consultant will conduct: 1) Definition of Current Conditions, Inception Report, and Workplan; 2) Technical Analysis; 3) Feasibility Analysis of the Project; 4) Project Implementation Plan; and 5) Final Report. The U.S. firm selected will be paid in U.S. dollars from a $492,000 grant to the Grantee from USTDA. A detailed Request for Proposals (RFP), which includes requirements for the Proposal, the Terms of Reference, and a background desk study report are available from USTDA, at 1000 Wilson Boulevard, Suite 1600, Arlington, VA 22209-3901. Requests for the RFP should be faxed to the IRC, USTDA at 703-875-4009. In the fax, please include your firm?s name, contact person, address, and telephone number. Some firms have found that RFP materials sent by U.S. mail do not reach them in time for preparation of an adequate response. Firms that want USTDA to use an overnight delivery service should include the name of the delivery service and your firm's account number in the request for the RFP. Firms that want to send a courier to USTDA to retrieve the RFP should allow one hour after faxing the request to USTDA before scheduling a pick-up. Please note that no telephone requests for the RFP will be honored. Please check your internal fax verification receipt. Because of the large number of RFP requests, USTDA cannot respond to requests for fax verification. Requests for RFPs received before 4:00 PM will be mailed the same day. Requests received after 4:00 PM will be mailed the following day. Please check with your courier and/or mail room before calling USTDA. Only U.S. firms and individuals may bid on this USTDA financed activity. Interested firms, their subcontractors and employees of all participants must qualify under USTDA's nationality requirements as of the due date for submission of qualifications and proposals and, if selected to carry out the USTDA-financed activity, must continue to meet such requirements throughout the duration of the USTDA-financed activity. All goods and services to be provided by the selected firm shall have their nationality, source and origin in the U.S. or host country. The U.S. firm may use subcontractors from the host country for up to 20 percent of the USTDA grant amount. Details of USTDA's nationality requirements and mandatory contract clauses are also included in the RFP. Interested U.S. firms should submit their Proposal in English directly to the Grantee by 12:00 noon, June 30, 2005 at the above address. Evaluation criteria for the Proposal are included in the RFP. Price will not be a factor in contractor selection, and therefore, cost proposals should NOT be submitted. The Grantee reserves the right to reject any and/or all Proposals. The Grantee also reserves the right to contract with the selected firm for subsequent work related to the project. The Grantee is not bound to pay for any costs associated with the preparation and submission of Proposals.
