Monitoring water quality is essential for protecting rivers, drainage systems and surrounding ecosystems during construction and infrastructure projects. Activities such as excavation, groundworks and surface runoff can introduce sediment or contaminants into nearby watercourses if conditions are not carefully managed. Remote Datum provides advanced water quality monitoring systems that measure environmental indicators such as turbidity, conductivity and temperature in real time.
Effective water quality management depends on the consistent monitoring of key parameters, including pH, dissolved oxygen (DO), electrical conductivity (EC) and suspended solids such as turbidity and silt. Of these, elevated suspended solids are among the most common and potentially harmful pollutants. Excessive silt can reduce light penetration, lower dissolved oxygen levels and cause physical damage to aquatic habitats, ultimately impacting fish and other wildlife.
By utilising GPRS enabled technology, data can be transmitted in real time, allowing measurements to be recorded at user defined intervals ranging from 15 minutes to 24 hours. Should any parameter exceed pre set thresholds, instant SMS and email alerts are issued, enabling swift action. All data is displayed in clear graphical formats via a secure online portal and can be exported for further analysis and reporting.
Maintaining a continuous, auditable record of water quality parameters demonstrates due diligence and proactive pollution control, helping organisations meet environmental regulations and project specific requirements. Remote Datum Ltd provides robust remote monitoring systems designed to track these critical indicators accurately and reliably in real time.
Protecting watercourses from contamination is a significant challenge for many sectors, particularly the construction industry. Construction sites are, by nature, temporary and fast moving environments, with multiple activities taking place over a relatively short timeframe. During this period, contractors must manage ground conditions, surface water and rainfall, all while ensuring that site operations do not introduce pollutants into nearby streams, rivers or drainage systems.
The combination of exposed soils, heavy plant movement, material storage and changing weather conditions increases the risk of runoff carrying silt, debris or other contaminants into surrounding watercourses. Without careful planning and effective control measures, even routine construction activities can adversely affect local water quality.
Unfortunately, the construction industry can have a considerable impact on the water environment if risks are not properly managed, making proactive monitoring and mitigation essential to safeguard ecosystems and maintain regulatory compliance.
Electrical conductivity refers to water’s ability to carry an electrical current and is directly influenced by the concentration of dissolved inorganic substances within it. These include negatively charged ions such as chloride, nitrate, sulphate and phosphate, as well as positively charged ions including sodium, magnesium, calcium, iron and aluminium. In contrast, most organic substances such as oil, phenol, alcohol and sugar do not readily conduct electricity and therefore contribute little to conductivity levels.
When a discharge enters a watercourse, it can significantly alter conductivity depending on its composition. For example, a leaking sewer pipe is likely to increase conductivity due to elevated levels of chloride, phosphate and nitrate, whereas an oil spill may reduce conductivity. For construction and industrial sites, monitoring conductivity offers a practical and cost effective early warning system. Testing for every potential contaminant in every possible receptor would be both expensive and inefficient. Conductivity monitoring, however, can quickly indicate that an abnormal change has occurred, prompting further investigation and corrective action.
Remote Datum Ltd offers the RDL V01, an economical and fully autonomous monitoring system that uses GPRS mobile telemetry. Installed directly within a watercourse, the V01 continuously measures conductivity while automatically compensating for temperature variations that affect electrical readings. The unit is typically deployed when the water is known to be unaffected by site activities, or positioned upstream, to establish reliable baseline data. Once baseline conditions are confirmed, alarm thresholds can be configured remotely. If these limits are exceeded, instant SMS and email alerts are issued. All data is accessible through the Remote Datum web bureau in clear graphical formats and can be downloaded as a CSV file for further analysis in Excel or other spreadsheet software.
