Storm water
Storm water is a natural water body that forms when water vapor in the atmosphere condenses to form clouds and eventually falls to the Earth’s surface in liquid form. It is an important component of the Earth’s water cycle and has significant impacts on the natural ecosystem, agricultural production, urban life, and more. Storm water is not only a vital source of surface water but also plays a crucial role in water resource management, environmental protection, and urban planning.
Although storm water is of great significance in the natural water cycle and is a valuable resource in many regions, improper management or extreme precipitation events can lead to serious hazards. Effective storm water management, drainage system construction, ecological restoration, and flood control measures are key to reducing the negative impacts of storm water, protecting the environment,and ensuring public safety.
KACISE’s storm water monitoring solution will help relevant authorities protect the environment from the unpredictable impacts of storm water. Additionally, in the field of storm water harvesting, KACISE will also provide storm water collection solutions to assist users in monitoring the water levels and water quality of the collected storm water.
Storm water Monitoring System Solution:
1. Measuring Real-time Precipitation and River Water Level
Precipitation is a key indicator for measuring rainfall intensity, which directly affects decision-making in areas such as water resource management, flood warning, and agricultural irrigation. River water level is a crucial factor in determining the occurrence of flood disasters. Real-time precipitation can be measured using a tipping bucket rain gauge, while river water levels can be measured using an ultrasonic level sensor. The level sensor collects data at regular intervals, and when the data reaches a set threshold, an alarm signal is triggered. The ultrasonic level sensor from KACISE has a resolution of up to 0.1mm, an IP68 protection rating, and built-in temperature compensation. It can help you obtain accurate water level readings with minimal maintenance required.
| Rainfall（mm/h） | Possible Disasters: |
| 0 – 2 mm/h | No significant disasters |
| 2 – 5 mm/h | Small-scale water accumulation |
| 5 – 10 mm/h | Urban waterlogging, localized flooding |
| 10 – 20 mm/h | Short-term heavy rain, waterlogging, localized flooding, landslides |
| 20 – 50 mm/h | Floods, landslides, mountain floods, urban waterlogging, large-scale disasters |
| 50 – 100 mm/h | Heavy rain floods, mountain floods, landslides, large-scale urban waterlogging, farmland inundation |
| >100 mm/h | Extreme heavy rain, catastrophic floods, large-scale mountain floods, severe landslides, large-scale urban waterlogging |
2.Monitoring Storm water Quality
Monitoring the quality of Storm water is crucial for assessing pollution sources, protecting the aquatic ecosystem, and ensuring water quality safety. The parameters that need to be monitored in storm water include pH, turbidity, heavy metals, oil content, etc., which help assess the degree of pollution in the storm water and further reflect the level of atmospheric pollution.
| Types of Polluted Rain | Possible Disasters | Recommended sensor to use |
| Acidic or alkaline polluted rain | Corrosion of building materials, damage to plant growth, and impact on aquatic life. | pH sensor |
| Heavy metal polluted rain | Heavy metals are toxic, posing a threat to the environment and human health. | 600 Series Heavy Metal Analyzer |
| Organic pollutant rain | Eutrophication of water bodies, algal blooms, leading to a decrease in dissolved oxygen levels in the water. | BOD、DO Sensor |
| Oily polluted rain | Pollution of water bodies, forming an oil film on the surface, which reduces the dissolved oxygen content in the water. | Oil in water、DO Sensor |
| Sandstorm polluted rain | Pollution of water sources, affecting the human respiratory system. | Turbidity Sensor |
3. Monitoring River or Pipeline Flow and Velocity
Measuring storm water flow, especially the flow in drainage pipes and rivers after precipitation, is crucial for flood early warning, water resource management, and the operation and optimization of urban drainage systems. KACISE’s Doppler flowmeter is ideal for measuring the flow velocity and flow rate of liquids in pipelines. It can also measure water level and temperature, and is commonly used in open channels and pipelines.
4. Floodwater Level Monitoring
By installing level sensors in areas prone to water accumulation, the flooding situation can be monitored in real-time. When the water level becomes too high, an alarm will be triggered to alert users to take appropriate action and prevent further damage. KACISE’s capacitive level sensor is particularly suitable for such scenarios. In cases of deep water accumulation, radar and ultrasonic level sensors may be submerged or experience blind spots, leading to measurement failure. However, the capacitive level sensor has no blind spots and will not produce incorrect results, even if submerged in water.
