Urbanisation

Nowadays most people live in cities. Urbanisation often negatively influences water management or land use. One of the effects is flooding because many of the surfaces in towns and cities have become impermeable. Urban green spaces are very significant elements of any urban ecosystem, both due to its ecosystem dynamics and its essential contribution in well being of the human race.

Projects

  • LoRa sensors used in soil moisture monitoring network in The Hague

    Client - BAM (the Netherlands)

    Background to installing the monitoring network

    • The Lange Vijverberg street in The Hague consists of a tram rail route surrounded by many old linden trees.
    • A redesign brought about changes in the habitat of the linden trees. The municipality of The Hague, therefore, wanted to gain insight into the change in soil moisture. 
    • This had to occur in an easy, wireless and economical manner. That’s why Eijkelkamp Soil & Water opted to set up a LoRa monitoring network of soil moisture sensors for this project.
    • Both the operator and the client can observe the change in soil moisture on this platform, and adjust the irrigation plan as needed.

    What is LoRa?

    LoRa is a new way of communicating, where small amounts of data are sent via the LoRa network to a website page.

    Services provided

    Gateway, LoRa transmitters with 20 sensors, and an online platform for visualizing the data and operating the sensors.

  • Unique Chinese wetland park monitors water 24/7

    Project - Pilot conjunctive water supply system for Deyang, China
    Project partners
    - Deyang Department of housing, urban & rural planning and construction | Deyang Department of water affairs | Deyang water supply company | Chengdu University of technology | World WaternetUnesco-IHE Institute for water educationMetaMetaEijkelkamp Soil & Water

    Background

    • The Deyang area in southwest China was struck hard by an earthquake in 2008
    • Since then, reconstruction has taken place with a tremendous speed and the urban population grew exponentially
    • Due to this urbanisation, the city’s water supply system can not meet its rapidly growing water demand

    Pilot project

    • A pilot artificial recharge water supply system was developed
    • This system benefits from the technology as introduced in the Amsterdam dune system that forms the main source of drinking water for the city
    • The water supply system increases groundwater storage, maintains constant water supply and improves water quality

    Services provided

    • The whole water system, from intake to effluent, is constantly monitored by a series of automated instruments
    • All equipment has been delivered and installed by Eijkelkamp Soil & Water
