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

LA Department of Water and Power’s Recycled Water Division Selects InfoWater Suite for Infrastructure Management and Modeling.

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.


MWH Soft is a global leader in wet infrastructure engineering modeling, simulation and management software and professional solutions designed to meet the technological needs of water, wastewater, and stormwater utilities, government agencies, engineering organizations and academic institutions worldwide. With offices in North America, Europe, and Asia Pacific, MWH Soft product lines empower thousands of engineers to competitively plan, manage, design, protect, maintain and operate highly efficient and reliable infrastructure systems.
