New Recycling Plant in Delhi to Boost Supply by 11 MGD

The second water recycling plant was recently launched by the Delhi Jal Board (DJB) at Wazirabad to improve the supply system by feeding two underground reservoirs in the area. The 11-million-gallons-per-day project is in addition to a 16-MGD recycling plant that was commissioned at Haiderpur last year.

The plant will be the first in the country to recycle water used in the initial stages of treatment so that there is no wastage. About 8% of water goes waste in various stages of treatment. At Haiderpur, it is this eight per cent that is recycled. Only sludge will remain as a byproduct and that too will be transported to Sonia Vihar for use in landfilling.

‘‘The Wazirabad treatment plant was built at a cost of Rs 27.8 crore, a sum that will be recovered within three years of operation. The water will feed two underground reservoirs at Burari and benefit about 2.5 to 5 lakh consumers in their command areas.

DJB’s old plants will now be equipped with recycling units. ‘‘The new plants, including Sonia Vihar, will have an in-built recycling unit. By the time all the four old treatment plants become functional, Delhi will have an additional 45 MGD water at its disposal.

Water from the two already-commissioned recycling plants will benefit about 7-8 lakh residents. A 10-MGD recycling plant at Bhagirathi is undergoing trial runs, while another 8-MGD plant at Chandrawal is likely to be commissioned by March this year.

Delhi Jal Board is setting up two more recycle water treatment plants, the first of their kind in the country, in Bhagirathi and Chandrawal complexes. It already commissioned one in Haiderpur last year. By March 2010, these plants will collectively add a total of 45 MGD to the city’s water supply.

The new recycling plant at Wazirabad complex, which gets 80 per cent of its raw water from river Yamuna, recycles “once treated water” and not raw water. So, the water is more potable.

MWH Soft Technology to Assist City of Los Angeles in Efforts to Save Billions of Gallons of Water Annually

MWH Soft, a leading global innovator of wet infrastructure modeling and simulation software and technologies, has announced that the Los Angeles Department of Water and Power (LADWP) Recycled Water Division has chosen MWH Soft’s industry-leading InfoWater Suite software as its advanced water network modeling solution. The suite enhances the enterprise’s comprehensive ArcGIS-centric (ESRI, Redlands, CA) strategy for managing its water distribution system. The selection further substantiates MWH Soft’s continued dominance of the geospatial hydraulic infrastructure modeling and management market.

The Los Angeles Department of Water and Power was established more than 100 years ago to provide a reliable and safe water and electricity to City residents and businesses. In May 2008, LADWP officials unveiled the City of Los Angeles Water Supply Action Plan, “Securing L.A.’s Water Supply,” which pledged to meet all new demand for water – about 100,000 acre-feet per year (123 million m3/yr) by 2030 – through water conservation and recycling rather than by importing of additional water. Since then, the City’s total use of recycled water is up to 7,200 acre-feet per year (8.9 million m3/yr). The water is used for irrigation and industrial purposes, and for environmental uses, including serving as a barrier to seawater intrusion.

All recycled wastewater in Los Angeles undergoes treatment and disinfection to the tertiary level and meets stringent water quality standards set by the California State Department of Public Health. The treated water travels to the end user through a network of pipes that are painted purple to differentiate them from those that carry potable water.

“LADWP’s use of our software to help manage its recycled water system sends a message that our products are not only powerful and easy-to-implement, but help drive sustainability in our industry,” said MWH Soft Vice President-Director of Americas Operations J. Erick Heath, P.E. “Our products are known for delivering consistent, high quality engineering GIS modeling data; enhanced efficiency; and reliable, cost-effective planning options. These powerful advantages are sparking measurable improvements in productivity, system performance, return on investment, and customer satisfaction around the world.”

Built atop ArcGIS using the latest Microsoft.NET and ESRI ArcObjects component technologies, InfoWater seamlessly integrates advanced water network modeling and optimization functionality with the latest generation of ArcGIS. It not only addresses all the operations of a typical water distribution system, but allows engineers to accurately perform the most difficult hydraulic analyses – including multi-point and extended period fire flow simulations, variable speed pumps, and advanced water quality calculations – and showcase the results using the rich presentations tools native to the ArcGIS environment.

The software delivers world-record performance, scalability, reliability, functionality and flexibility directly within the GIS setting, completely eliminating the need for inefficient, unreliable data synchronization, synching schemes, or middlelink interfaces required by other software. These factors and more translate to increased productivity, reduced costs, greater efficiency, and improved designs.
