Tender: Sanitation solutions for underserved communities in Jordan

The project, initiated by the Swiss Agency for Development and Cooperation (SDC), focuses on rethinking sanitation systems, by improving existing Wastewater Treatment Plants (WWTP) and exploring the development of small scale Waste Water Treatment (WWT) and Faecal Sludge Treatment (FST) solutions. The goal of these improvements and developments is to increase WWT efficiency and sanitation coverage, and turn waste streams into physical and financial resource streams by ensuring and promoting safe reuse of the treated wastewater and faecal sludge. The focus is on Jordanian host communities as a whole, with a particular attention to be paid to unserved, vulnerable communities, as they are more and more impacted by the lack of adequate sanitation systems. The project will be subdivided into two distinct phases – the inception phase and the main phase.

Costa Rica: Govt developing US$270mn wastewater treatment plan

Costa Rica’s state water utility AyA will invest US$270mn to start treating the 2,800l/s of wastewater currently produced in the greater metropolitan area in and around capital San José, local paper La Nación reported.

The project involves the rehabilitation and reconstruction of the sewerage networks in nine municipalities in San José and one in Cartago province. A total of 360km of secondary pipelines will be installed and four trunk sewers will be repaired.

A wastewater treatment plant will also be built in the La Uruca municipality.

A US$17.4mn tender to carry out studies and draw up the master plan for the underground network was awarded to a consortium formed by Japanese NJS and the French firm Sogreah on January 22.

Pending contracts include the construction of the underground network and for the wastewater treatment plant. Two Spanish firms and a French firm are participating in the tender process to build the plant, the report said.

The initiative is being financed with a US$130mn loan from the Japan Bank for International Cooperation (JBIC). Another US$140mn will be provided from the country’s own resources.

Upon completion in 2015, wastewater produced by the 1mn people living in the San José municipalities of Desamparados, Goicoechea, Alajuelita, Vázquez de Coronado, Tibás, Moravia, Montes de Oca, Curridabat and Central will be treated. La Unión municipality will also benefit.

Currently, wastewater from these municipalities is disposed of without treatment in the rivers Torres, María Aguilar, Rivera and Tiribí.

Latin America: wastewater treatment moves into high gear

Although levels of wastewater treatment are still quite low in Latin America compared to developed countries, notable progress has been made over recent years and opportunities abound, according to the January BNamericas infrastructure intelligence series report [1]. Some Latin American countries have managed to reach wastewater treatment levels of over 80%.

Historically a low priority in comparison to water capturing and distribution, wastewater treatment is finally making it onto the agenda of the region’s biggest economies.

Attractive markets for investors include Mexico, Brazil and Peru, where governments are promoting public works programs not only to increase potable water and sanitation coverage, but also to clean up and preserve resources.

At the same time, the effects of climate change are causing drought throughout the region, prompting authorities to worry more about their dwindling resources. The need to reduce pollution levels in rivers, lakes and along the coast has wastewater treatment plans in full swing.

The Peruvian government is actively looking for private sector investment and a plan to raise wastewater treatment from the current 15% to 100% by 2015 is underway. In addition, last year the national standards for water quality were approved, setting new levels for treated wastewater.

Meanwhile, in Mexico authorities have set the goal of treating 60% of wastewater by 2012 and recently awarded a tender to build one of the largest wastewater treatment plants of its kind in the world, Atotonilco.

Brazil, on the other hand, has been making slow progress. Despite government investments of 4.5bn reais (US$2.5bn) a year over the last three years, only 32% of collected sewage is currently treated. Experts agree that the only way to revert this situation is by handing over more concessions to the private sector.

Honduras, Tegucigalpa: Sanaa may reject faulty wastewater treatment plant, says director

Honduran national water authority Sanaa may reject the EU’s donation of a wastewater treatment plant for capital Tegucigalpa due to faults in its design and construction, Sanaa director Jack Arévalo told BNamericas.

“The plant does not fulfill the expectations specified in the contract,” Arévalo said.

“It has several flaws, mainly in its design,” Arévalo added.

The wastewater treatment plant was designed by an Italian firm and built by an Italian-Honduran consortium, and was financed by a 26.7mn-euro (US$38.9mn) donation from the EU, according to Arévalo.

The plant has still not been officially received by Honduran authorities, as the project, which began in 2007, is still not complete. Sanaa expects the plant is to be finished by mid-2010.

An inspection carried out recently revealed that the plant is currently working at 35% of its total capacity. Although not complete, the plant should be capable of working at 100% capacity, Arévalo said.

Located in the San José de la Vega district, the plant is expected to treat 20% of Tegucigalpa’s wastewater, and serve some 200,000 inhabitants.

Nicaragua: Enacal requesting US$5.78mn for sanitation

Nicaraguan national water and sewerage utility Enacal needs to invest some 120mn córdobas (US$5.78mn) to repair and remodel 25 wastewater treatment plants throughout the country in 2010, local paper La Prensa reported.

The repairs and upgrades are required to avoid a collapse of the sanitation system in several departments. In some cases, the plants have received no maintenance work over the last 10 years, according to Enacal head Ruth Selma Herrera.

The initiatives are included in Enacal’s 2010 investment plan. However, the utility currently lacks the resources to carry out the works, and is requesting financing from several international organizations and cooperation funds.

Enacal has presented its plan to Japanese organizations and IDB, and hopes to receive a loan or donation as soon as possible, the report said.

Sri Lanka: capital to get better wastewater system

The Asian Development Bank is helping to fund the [Greater Colombo Sewerage System] project to improve wastewater disposal in the Sri Lankan capital Colombo under which only treated effluent will be discharged into the sea. The 135 million dollar project covers the Colombo municipal area as well as suburbs to the north and south of the city. Defunct wastewater treatment plants at the two outlets to the sea will be replaced with modern treatment plants under the project.

The project is being handled by the state-owned National Water Supply and Drainage Board, and the Colombo municipal council.
