Water Level Monitoring Polder PWN, North Holland

North Holland, Netherlands
Project duration:  2022 – present
PWN monitors water levels in a designated polder to maintain water quality and reduce hydraulic pressure from surrounding areas. Increasing periods of drought have raised the need for frequent, accurate monitoring. Basetime supports this process through the deployment of the Locator One, enabling continuous and automated water level measurements.

 

Basetime device supporting Polder PWN water level monitoring in North Holland, providing continuous automated measurements for water management.

Protecting the retention area to ensure a sustainable supply of clean drinking water.

Project Purpose

The objective is to gain detailed insight into water level dynamics in a controlled polder with minimal external influences, ensuring optimal water quality and management. Continuous monitoring enables PWN to respond quickly to drought conditions, rainfall, and other environmental changes.

Implemented Solution

Locator One units were installed on simple structures such as poles or wooden frames. The GNSS antenna logs positional data while the radar sensor measures the distance to the water surface. All data is sent automatically to the cloud, processed within the Basetime platform, and integrated into PWN’s management system for direct analysis.

Key Results

Technical Requirements

Continuous insight into water levels.

Automated alerts when water level thresholds are exceeded.

Minimal disturbance to natural surroundings.
