Optimization of drinking water quality in the Northwest Russian Federation

With the aim of upgrading drinking water supply in Northwest Russia, Fichtner developed a regional program to ensure continuous monitoring of drinking water quality. Among the primary project tasks was to determine the root causes for deterioration of raw and drinking water quality over the past twenty years, develop pilot projects, work out recommendations for alternative drinking water supply concepts, and devise innovations in drinking water management while developing the basis for a tariff system to cover costs.

Construction of Manantali Dam and Hydropower Plant in Mali

Thanks to construction of the new Manantali Dam, this multi-purpose scheme permits year-round irrigated agriculture over an area of 375,000 ha in the Senegal Valley while improving river navigability. A further objective of the 1600 m long and 70 m high dam is electricity generation by a 200 MW hydropower plant. For this project, within the framework of general project management, Fichtner prepared preliminary and feasibility studies as well as undertook conceptual and detail planning, construction supervision and commissioning.

Flood protection and groundwater recharge, Oman

The Batinah Region in the densely populated coastal strip in Northern Oman is in danger of flooding. Fichtner is preparing a feasibility study for protecting the endangered areas. Following an analysis and appraisal of the present situation, protection measures in the form of floodwater retention basins and protective embankments are specified and planned. For Oman’s water supply, which is primarily based on groundwater, an investigation is made into maximizing groundwater recharge beneath the impoundments. Fichtner provides construction supervision for the civil works.

Wastewater recycling in the City of Riyadh, Saudi Arabia

Due to the huge growth of the Saudi Arabian capital, fresh water resources have become scarce. Fichtner has therefore been awarded a contract to develop a scheme for reusing treated effluent from the wastewater treatment plants in Riyadh. Our engineers are designing concepts for recycling the wastewater generated by around six million inhabitants within the entire metropolitan area. Investigations are underway for reuse of this water primarily for agriculture, but for other purposes, too, like in industry or for irrigating greened areas. Also being studied is how groundwater reserves can be recharged with the treated wastewater.

Pahang-Selangor raw water transfer project, Malaysia

To meet the rising demand for water in Kuala Lumpur and in the State of Selangor, the intention of this project is to allow transfer of 1.9 million cubic meters of raw water per day from the State of Pahang. The components of the Pahang-Selangor Raw Water Transfer Project are erection of a 30 m high dam at the Kelau River, a water intake structure with pumping station at the Semantan River, an 11.8 km long pipeline as well as a water transfer tunnel that, with a length of 44.6 km, is among the longest tunnel structures in Asia. To a major part, the project is financed by a soft loan from the Japan Bank for International Cooperation (JBIC) and is to be completed in 2013. As independent reviewer and consultant, Fichtner is supporting the Ministry of Energy, Water and Communications in Malaysia in implementing this project.

Framework water resources plan, Ecuador

Within the metropolitan area and City of Quito, municipal and industrial wastewaters are discharged untreated into the rivers and contaminate not only surface watercourses but also the groundwater. Fichtner was commissioned with drawing up a masterplan for rehabilitation and maintaining the cleanliness of the rivers in the City of Quito and its surroundings, with a population of 2.2 million. A key component of the investigation is determination of the extent of pollution of the main rivers that are used as receiving waters, with identification of the sources of contamination, together with a comparison of prospective measures and their planning with elaboration of a monitoring model.
