Engineering Modeling Applications

Models of water distribution systems have a long history — likely longer than most realize. However, in recent decades, the functional capabilities, user interfaces, and processing algorithms have markedly improved. While many professionals in the water sector may have reviewed or even developed a model in the past, today's practice of modeling has evolved significantly, and with the proliferation of advanced technology throughout the water sector, tomorrow's engineers and operators will commonly use even more advanced models of our vital water infrastructure.

Emergency Preparedness Modeling for Distribution Systems

Water Main Rehabilitation

The nation’s water infrastructure, especially the underground pipes, is aging and in need of significant reinvestment. Like many of the roads, bridges, and other public assets on which the country relies, most of our buried water infrastructure was built 50 or more years ago, in the post-World War II era of rapid demographic change and economic growth. In some older urban areas, many water mains have been in the ground for a century or longer. Given its age, it comes as no surprise that a large portion of U.S. water infrastructure is approaching, or has already reached, the end of its useful life.

The pipe is primarily intended for use in transporting potable water, wastewater, and reclaimed water in buried installations. Pipe outside diameters (OD) conform to those established for CI-equivalent ODs (CIOD). Pressure classes range from 165 psi to 305 psi (1,140 kPa to 2,100 kPa) in sizes 4 in. through 24 in.

WaterSmart Innovations 

The world of water is finite. Find new ways to protect and conserve.

Wastewater Collection Systems

Wastewater collections systems are comprised of gravity pipes, manholes, tanks, lift stations, control structures, and force mains that gather used water from residential and nonresidential customers and convey the flow to the wastewater treatment plant. It takes thousands of miles of pipeline to collect this wastewater so it can be treated and returned to the environment.

Water Resources Planning & Sustainability

Water resources planning includes range estimating future water demand to evaluating possible new sources of water, protecting water sources, and addressing expanding environmental regulations. A water resources plan should bring together a myriad issues, interests, and stakeholders through a planning process that can result in a reason-based, cost-effective, and an environmentally sound plan the public can support.

Source Water Protection

Protecting sources of drinking water is an effective way to reduce risks to public health, instill customer confidence, and control water treatment costs. Addressing water quality concerns at the source also has many other environmental and societal benefits that are not seen from treatment alone.

PFAS

Per and polyfluoroalkyl substances are persistent synthetic compounds used in a variety of industrial and consumer product applications including non-stick cookware and firefighting foams. The presence of PFAS compounds in source water and drinking water is of increasing public concern due to their widespread use and environmental persistence. The resources included on this page provide information and guidance for water professionals challenged to address this contaminant.

Water Quality from Source to Tap

Water quality refers to the chemical, physical, and biological properties of water. Water quality requires management from source to tap, and certain standards are enforced to protect public health.

Water Conservation

Water conservation focuses on taking action to improve the effectiveness of water use through various means, such as choosing to change behavior by using those fixtures and appliances less. Water efficiency often refers to the state of water use in a community, and higher levels of efficiency implies the community uses less according to metrics such as gallons per person per day or gallons per acre of irrigated area.

Waterborne Pathogens

A goal of drinking water and wastewater treatment is to reduce the numbers of viable organisms to acceptable levels, and to remove or inactivate all pathogens capable of causing human disease. Despite the remarkable success of water treatment and sanitation programs in improving public health, sporadic cases and point-source outbreaks of waterborne diseases continue to occur. Waterborne pathogens include the microorganisms Giardia, Cryptosporidium and Legionella.

Groundwater

Groundwater exists below the earth’s surface in the space between soil and rocks. Groundwater is a source for many drinking water supplies, especially for rural communities. Learn more about groundwater supplies, storage, and recharge.

Wastewater

Water utilities are increasingly viewing wastewater as valuable source of drinking water and how the water and wastewater industries are very similar in the overall size of both industries, and how they both use the same technological approaches and systems. Both industries are faced with critical need for infrastructure replacement and capital expenditure.

Climate Change

Climate variability impacts the hydrologic cycle, source water, and water demands and in turn the long-term quantity, quality, and reliability of water supplies. Addressing impacts due to climate change includes assessing risk and uncertainty as well as improving resiliency and sustainability in utility management, facilities, and water sources.

Potable Reuse

The quality and quantity of conventional water supplies are increasingly affected by population growth, urbanization, prolonged and severe droughts, and climate change. With an increased pressure on water systems, a diversified portfolio of water sources is required to meet future water demands, ensure public health, and provide economic and environmental sustainability. One viable approach to address existing and anticipated water shortages is to implement water reuse.

Rates & Finance

Implementation of sound principles regarding the design and application of water rates and charges for water service is a critical part of the water industry. Additionally, uniformity in water utility accounting policies and procedures is required for best business practices.
