South Tahoe Public Utility District Switches to MWH Soft Advanced Geospatial Technology


Comprehensive Evaluation Confirms Superiority of InfoWater and InfoSewer ArcGIS-Centric Modeling Solutions for Water Distribution and Sewer Collection Systems

Broomfield, Colorado USA — MWH Soft, a leading global provider of environmental and water resources applications software, today announced that the South Tahoe Public Utility District (STPUD), California, has chosen MWH Soft’s industry leading InfoWater Executive Suite and InfoSewer Suite software to supplant its existing water and sewerage network modeling solutions.

After a comprehensive evaluation of a number of vendor offerings, STPUD selected the InfoWater and InfoSewer all-in-one water and sewer modeling solution. The software suites were chosen because they deliver powerful geocentric modeling functionality and ease of use in an affordable package. The suites will provide the district with the foundation it needs to develop a comprehensive ArcGIS-centric (ESRI, Redlands, CA) solution for operating and managing its drinking water and wastewater systems. The selection further substantiates MWH Soft’s leadership position in geospatial hydraulic infrastructure management in the North American market.

The accelerated adoption rate of MWH Soft geospatial technology across the continent reflects a powerful trend among water and wastewater utilities and progressive engineering firms toward MWH Soft products. The shift is being driven by a range of compelling factors, including unparalleled ArcGIS integration; speed; brevity of learning curve; powerful, comprehensive feature set; and superior technical support.

South Tahoe Public Utility District, formed in 1950, provides sewer and water service to the community of South Lake Tahoe. The District’s water system is organized into 16 pressure zones serving over 2.4 billion gallons annually from 14 active drinking water wells. The collection system comprises 420 miles of sewer lines, 39 lift stations and 17,000 connections.

“We standardized on InfoWater Executive Suite and InfoSewer Suite because they deliver a broad range of powerful modeling and design functions that operate directly within our ESRI-based GIS platform,” said John A. Thiel, PE, MBA, Principal Engineer with STPUD. “These engineer-friendly packages will allow us to improve our current water and sewer modeling performance by establishing a standard geocentric modeling platform from which we can quickly and more accurately construct and analyze our water and wastewater network models. These improved capabilities will lower our maintenance costs, help us optimize our water and sewer capital planning, and improve the management and operation of our water and wastewater systems.”

Built atop ArcGIS with native geodatabase support, InfoWater and InfoSewer offer a single comprehensive, GIS-centric solution for analyzing and managing the most complex water distribution and sewer collections systems. A seamlessly integrated geospatial framework applies GIS intelligence to engineering-accurate information, coupled with the most advanced numerical computation, genetic algorithm optimization and object-component geospatial technologies in the marketplace. The resulting centralized, multi-function system enables world-record performance, scalability, reliability, functionality and flexibility within the powerful ArcGIS environment, 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 — giving water and wastewater utilities a clear competitive advantage.

“Effective management of water and wastewater systems requires GIS-centric modeling software that lets engineers focus on solving critical design challenges, not software workarounds,” said Paul F. Boulos, Ph.D, President and COO of MWH Soft. “We are proud that a record number of water and wastewater utilities and engineering organizations worldwide are relying on our superior geospatial technology to deploy rigorous, high performance GIS-centric modeling and optimization systems. Clearly, no other solution offers such a powerful combination of GIS-centric functionality, speed, reliability, and ease of use in support of better decision making and more economical operations. We are pleased to add STPUD to the fast growing list of progressive organizations moving to our state-of-the-art geocentric modeling applications. Together, they are helping to make these applications the standard for the North American water and wastewater industries — as our solutions help them to thrive.”

“By far, MWH Soft offers the most comprehensive selection of ArcGIS-centric hydraulic network modeling and management solutions in the water and wastewater industries,” said J. Erick Heath, P.E., Vice President of Sales and Client Relations at MWH Soft. “We design each of these critical tools to help our customers do their jobs better, faster, easier and at lower cost. We’re proud to know that InfoWater and InfoSewer will be helping STPUD build a solid foundation for success in the decades to come.”
