A new residential and commercial development in
Sydney will include a dedicated wastewater recycling facility. According to
Sydney Water, it is the largest project of its kind in the world and will set
the standard for water reuse and efficiency in new developments across the city.
The operator of the development, Central Park
Water, will source drinking water from Sydney Water and supply it to more than
2,000 residential apartments and 75,000 square meters of commercial and retail
space. The water recycling facility will collect and treat the wastewater, then
distribute the recycled water for “grey water” uses including the flushing of
toilets, laundry and car washing, which together make up 50 percent of
traditional potable water use.
Sydney Water general manager Paul Freeman said,
“The Central Park project is an excellent example of Sydney Water working
cooperatively with the private sector to drive innovation and efficiency to
benefit New South Wales water users.”
Cambi UK has been awarded a contract for one of the largest sludge treatment projects in China. Cambi will supply its proprietary thermal hydrolysis process (THP) to Beijing’s largest wastewater treatment plant (WWTP) in Gaobeidian, with a treatment capacity of 1 million m3/d (264 MGD). The retrofit will produce biogas from anaerobic digestion, as well as a clean biosolids product for use as fertilizer. The technology will be fitted and operating by 2016.
This is Cambi’s first commercial-scale project in Asia. The owner of the WWTP, Beijing Drainage Group, is planning four other similar projects for a 2016 to 2017 timeframe. When operational, the five sludge plants would treat a combined total of 6,000 tonnes/day of sludge.
The Chinese government has selected the Canadian company Analytica Bio-Energy Corp to take the lead in designing and building advanced municipal wastewater treatment facilities throughout the country. Analytica’s patented NH3-N wastewater treatment system is effective in removing ammonia and nitrogen from wastewater, which can lead to eutrophication in water bodies. The NH3-N system combines ultrafiltration equipment, microfiltration, reverse osmosis equipment and EDI equipment in various combinations.
Analytica will initially design, build and operate a pilot-scale treatment facility with a treatment capacity of 600,000 tons/day in Shenyang City, the largest city in Liaoning Province. The Chinese government then plans to promote the technology at the national level in order to meet the new urban draining and sewage treatment standards which became effective in January 2014.
Sound Global, a leading provider of water and wastewater treatment solutions in China, has announced the approval of several expansion projects and the award of new contracts, including:
Jiangnan STP Expansion: Under a Build-Operate-Transfer (BOT) model, Stage I of Phase I of the Jiangnan Sewage Treatment Plant in Chongzuo City, Guangxi Province, was constructed by Sound Global in 2008 with a capacity of 15,000 tonnes per day. Stage II, with a capacity of an additional 15,000 tonnes/day, has been approved by the Municipal Government of Chongzuo City. Upon completion, the STP will have a total capacity of 60,000 tonnes/day, at a cost of RMB68.21 million (US$11 million) and with a concession period of 26 years.
Tongliao STP Expansion: Sound Global’s sewage treatment plant in Tongliao City was constructed in 2007 with a treatment capacity of 100,000 tonnes/day and is designed to meet Class 1A discharge standards. An expansion of the STP has been approved by the Municipal Government of Tongliao City, Inner Mongolia, which will add an additional 50,000 tonnes/day of capacity, at a cost of RMB100 million (US$16 million) and with a concession period of 30 years.
Jiangsu STP O&M: Sound Global has been awarded a 25-year Operation and Maintenance (O&M) contract for four sewage treatment plants located in three towns in Jiangsu Province. The plants have a combined capacity of 18,000 tonnes/day and are designed to meet Class 1A discharge standards.
Sound Global is incorporated in Singapore as a holding company for business operations in China. The company’s services span the entire value chain for water and wastewater treatment, including design and construction, operation and maintenance and the manufacture of water and wastewater treatment equipment.
The Delhi Jal Board (DJB) has drafted a Rs. 19,500-crore (US$3.2 billion) master plan to address the city’s failing wastewater management system and reduce pollution in the Yamuna River. Delhi’s 35 wastewater treatment plants can deal with only 40 percent of the total sewage generated by the city due to the lack of infrastructure and blocked sewage lines. Untreated sewage flows directly into the Yamuna River, which supplies 70 percent of the city’s drinking water.
The DJB was criticized in the latest report issued by comptroller and auditor general (CAG), which said, “Delhi Jal Board was formed in 1998 to manage sewage but is yet to have a sewerage master plan.” The Sewerage Master Plan 2031 has since been prepared and proposes a 10,000-km pipe network and 75 additional WTPs. DJB is in the process of soliciting comments on the plan from NGOs and other organizations so that the plan can be finalized in October.
Quang Nam Province has approved a VND244 billion (US$11.5 million) wastewater treatment project for the ancient coastal town Hội An in central Vietnam. The plant will have a capacity of 2,000 m³/day (525,000 gpd) and will be built near the Cau Pagoda Bridge in the town’s Cam Pho Ward. Also known as the Japanese Bridge, the bridge was constructed around the 17th century by Japanese merchants. In 1999, Hội An was declared a world heritage site by UNESCO for being a well-preserved example of a Southeast Asian trading port, and for housing buildings with a unique blend of local and foreign influences.
The project will be co-funded by the Japanese and Vietnamese governments.
The new £200 million (US$325 million) wastewater treatment complex at the Wellington Dock in Liverpool is on track for completion in the spring of 2015. Construction began in the fall of 2012. Three basins are currently being tested for leaks and the next stage will involve the construction of a roof on the treatment plant building.
A 285-meter long outfall pipe has been installed on the bed of the Mersey River, which will take treated wastewater into the middle of the river. It will then hit strong tidal currents and be dispersed more widely into the estuary and Irish Sea. This will reduce the risk of pollution to the coastline and continue a three-decade effort to clean up the Mersey River, which was once named the dirtiest river in Europe.
With AMP6 set to being in 2015, Southern Water has started to name the firms it will use in its £3 billion (US$4.9 billion) investment program for 2015-2020. Joint ventures headed by Costain and Galliford Try have been awarded projects worth £200 million (US$325 million) and £380 million (US$620 million), respectively. Costain and partner MWH will maintain and improve water supply and wastewater treatment works in the eastern half of Southern Water’s region (Kent and East Sussex), and Galliford Try and partners Imtech and Atkins for the western half of the region (West Sussex, Hampshire and the Isle of Wight). In a separate joint venture with Morrison Utility Services and AECOM, Galliford Try will also expand and maintain a network of water mains and sewers.
Later this year, Southern Water will announce which companies will be supporting the day-to-day repair and maintenance of its network of water mains and sewers, as well as its water supply and wastewater treatment works, during 2015 to 2020.
The Water Services Regulation Authority, or Ofwat, regulates the price charged for water and sewerage service in England and Wales based on 5-year Asset Management Plans (AMP) submitted by water utilities. Ofwat’s guidelines for the 6th AMMP from 2015-2020, promote a shift from large capital investments to efficiency improvements and sustainable operations.
Xylem has signed a US$7.3 million contract with Bahrain's Ministry of Works to upgrade the Tubli Wastewater Treatment Plant in the capital city of Manama. Under the contract, Xylem will design, install and commission an expansion of the facility from 200,000 to 240,000 m3/day (53 to 63 MGD).
Xylem will also expand the existing Wedeco ozone system, resulting in the largest ozone facility in the Middle East and increasing the amount of treated wastewater suitable for reuse in agriculture. The upgrades are expected to be completed by the end of 2015.
The German Development Bank (KfW) has approved funding for water and wastewater projects in Zarqa and Amman worth €80 million (US$100 million). The new funds are intended to help alleviate the burden shouldered by the Kingdom in hosting hundreds of thousands of Syrian refugees. Specific projects targeted by the funds include:
• A 20-km pipeline to convey 80,000 m3/day (21 MGD) of sewage from the Zarqa Governorate and parts of Amman to the 5-year old Al Samra Wastewater Treatment Plant, which treats 75 percent of the country’s sewage.
• A sludge management project at the Al Samra WWTP to covert sludges into fertilizer and bio-fuels and protect groundwater from contamination.
• New sewage networks, a wastewater pumping station and a sewage pipe in Zarqa’s heavily populated Al Sukhneh and Al Hashimiyeh districts.
Abu Dhabi’s population is expected to more than double over the next 15 years, from 2.3 million today to over 5.0 million by 2030. The demand for potable water will also double. In the past, water deficits in the Middle East have been met primarily by adding desalination capacity. However, the Abu Dhabi Sewerage Services Company (ADSSC) is undertaking a multi-billion Dirham project to achieve 100 percent wastewater reuse.
The emirate currently generates 284 million cubic m3/year (75 billion gallons/year) of sewage. Sixty percent of the sewage is treated for reuse as irrigation water for farmland and parks. The primary obstacle to increasing that percentage is the lack of pipeline systems for transporting sewage to the treatment plants. ADSSC is, therefore, focusing its investment on an expansion of its sewage collection and transfer systems.
Alagoas state water utility Casal has awarded a sewage project worth US$767 million to South Korean company GS Engineering &Construction. GS Inima, a subsidiary of GS E&C, and two Brazilian construction firms, STE and Enorsul, will build two new sewage treatment facilities in the northeastern city of Maceio. When completed in 2018, the facilities will process wastewater from nearly 35,000 households. The contract also calls for the consortium to operate and maintain the two new facilities, along with a third existing facility, for 30 years.
GS E&C acquired Spanish desalination and water treatment firm Inima in 2012 to establish GS Inima. "We have started to see synergy from the acquisition,” according to Doe Jae-seung, senior vice president of GS E&C. GS Inima Brazil has been operating four water treatment facilities in San Paolo and is the fifth largest company in Brazil in terms of sales in the water treatment business.
Rio de Janeiro officials have unveiled a new sanitation project designed to eliminate the flow of raw sewage into Gloria Marina, the site of sailing events for the 2016 Olympics. More than half of the city’s sewage goes untreated, which means that collected rainwater is often contaminated with raw sewage. Consequently the US$6.2 million project will connect area rainwater drains to a sewage treatment center in the Ipanema Beach area. The project will also include a 1-km long pipeline to divert sewage from the city's Flamengo neighborhood away from the Marina.
In Rio's Olympic bid, officials pledged to slash the levels of sewage and garbage flowing into the Guanabara Bay by 80 percent in time for the Olympics. Plans were to activate long under-used or out-of service sewage treatment plants, install garbage-trapping nets at the mouths of rivers, and deploy a fleet of trash-collecting boats. The Rio government has been repeatedly criticized, however, for the sluggish progress of the cleanup.
Colombia’s Housing Ministry (Minvivienda) has announced plans to invest nearly US$61 million to improve sanitation and reduce pollution in its river basins and lakes. The Saneamiento para Vertimientos (Sanitation for Wastewater Discharge) program will address rising levels of contamination in rivers and lakes caused by municipal discharges of untreated wastewater. The funds will be allocated to 16 projects, targeting 10 of the country’s most polluted waterways.
A priority for the ministry is cleaning up the Bogotá River, the country’s most polluted waterway. Stretching 375 kilometers across the country’s central department of Cundinamarca, the river has long been a dumping ground for untreated sewage and industrial wastewater. According to a report in Colombian newspaper El Espectador, billions of pesos have been spent over the past two decades to clean up the sewage problem in the capital city of Bogota -- with “embarrassing results.”
Funds have also been earmarked for the contaminated upper Chicamocha River basin in northern Colombia, the Medellín River that flows through the country’s second most populous city, and the Upper Cauca River basin in the west of the country. The Suárez River, where it meets Lake Fúquene, the Fonce, Chinchiná, Otún and Consota river basins, the Oro River and the Quindío and La Vieja river basins will also to be targeted.
