Water Resource Management

Water resource management refers to the conservation, custody and transport monitoring of water as a natural resource. Measurements are made to quantify water for the purpose of protection, forecasting, management, lawmaking, enforcement, policymaking, resource allocation and public reporting. Stevens has been providing quality products for water management for over 100 years.

Effective management of watersheds must address the growing pressures caused by development on the natural function of rivers and floodplains. Planning for development and accommodating beneficial uses of water resources, while maintaining and enhancing the natural functions of these water resources, requires managers to consider many factors. These include water-related disasters such as floods and droughts, ensuring a sustainable water supply, protection and remediation of water quality, management of river sediments and soil erosion, balancing competing demands on supplies, and protection and restoration of riparian habitats.

Water shortage, water pollution and flood impacts are among the most urgent problems in river management. The number of flood disasters worldwide has increased significantly in recent years. While this may partly be due to a changing climate, the additional utilization of flood plains for transportation corridors, housing, and agriculture also results in a reduction of the natural capacity of catchments to attenuate runoff.

Dams and reservoirs store water for power, potable water supply, and irrigation, and are also used to mitigate the potentially devastating effects of floods and droughts. At the same time they may have negative environmental and social impacts. There is therefore an increasing demand for detailed and accurate assessments of the environmental impacts of these facilities, and for optimizing operation of existing dams to minimize the adverse effects while maximizing the benefits.

It is challenging to maintain quality water supplies to existing communities, let alone planning for the future growth. Much of the infrastructure utilized in the collection, treatment, and distribution of water is aging and requires assessment to determine the best replacement and rehabilitation strategies. Clean, efficient, and reliable water supplies ensure the sustainability of a community, with improved human health and economic viability. Wastewater planning is equally important for a community’s long term success. Efficient collection, treatment, discharge, and reclamation require water managers to leverage the best available technologies.




Water Level Sensors

Smart PT delivers accurate results for a wide range of fluid level measurement applications. In addition to simple instantaneous measurements, this smart sensor features the ability to capture peak crest levels, and to automatically sample and report basic statistics on a configurable time interval.


Extremely rugged design—potted electronics, high-impact PVC housing—make the SDX an excellent choice for hostile environments and applications that may put more expensive sensors at risk of damage or loss.

  • Will not be damaged by freezing water.
  • Vented cable provides an atmospheric reference.
  • 4-20 mA output.


Pressure sensors (also called pressure transducers or pneumatic pressure sensors) preform liquid level measurement by having the sensor submerged at a fixed depth under the water surface. The pressure sensor measures the equivalent hydrostatic pressure of the water above the senor diaphragm, using this to calculate the total liquid depth. This function of a pressure sensor can be compared to “weighing the water”. Pressure sensors are ideal for ground and surface water level applications.

Water Quality Sensors

This SDI-12/RS-485 sensor is ideal for high-accuracy readings in water, soil, and air. It features fully-potted components, robust PVC Type II housing, and marine-grade stainless steel, making the sensor ideal for harsh environments.


Stevens water monitoring stations will typically use either cellular or GOES for telemetry. For cellular (CDMA/GPRS/HSPA),  eTracker is a cellular gateway which provides “virtual” cloud-based data logging, and therefore doesn’t require a physical data logger. All data is sent to the cloud for storage (with a backup stored locally) and the station can be configured remotely. For GOES, we offer the Stevens SatComm GOES transmitter which is also available with an integrated data logger.

A power source is required (battery and solar panel is typical for remote deployments) and a power regulator. SOLO is great choice because it’s a solar charge regulator, intelligent power manager and power system sensor all-in-one (it also allows remote power cycling through eTracker).

Retrieving data is simple with Stevens-Connect, our cloud-based software that requires no infrastructure to scale to any number of stations or users. Use it to configure your station, visualize your data, analyze measurements, manage alarms, perform calculations, and set up data routing. Alternatively, you can have the data sent to any other HTTP or FTP destination or 3rd-party software like Aquarius or WISKI.

True cloud-based sensor configuration, logging, reporting and data analysis all-in-one. eTracker is the gateway between the sensors and the cloud̬—data communication and IT infrastructure merged under a single user interface experience.
