A simple, practical, and economic service to reduce
your water consumption to the strict minimum necessary for the lawn.

The necessary water, when necessary


A turnkey service: you receive your watering recommendations weekly in the unit of your choice: watering time, as percentage of a reference program or millimeter.

In direct contact with the roots: by measuring the water tension of the soil, our stations directly and continuously evaluate the water comfort of the lawn.

Foster a deep root anchoring


For a more resistant lawn: adapted water supply foster a deep anchoring for greater resistance to tearing off and water stress.

Indicators as control tools: you have informations day after day on the hydric comfort of the lawn and the root development in the soil.

Easy to use and functional guarantee


A simple and practical set up: our sensors are buried under the playgrounds. They do not require any wires, subscriptions or intervention from our customers.

The Urbasense team works with you: to ensure that maintenance, any repairs to our stations and all sensor communication costs are included in our packages.

Understand the service : more details

I have already a rain gauge or a weather station, is it usefull to add more?

The installations controlled by a rain gauge allow to avoid watering when it rains. This function is especially useful to avoid the reactions of the general public when watering under precipitation. Rainfall alone does not determine the water requirement of plants.

The potential evapotranspiration (from weather stations) is a local (or regional) data for an average soil, for an average crop. It allows a theoretical adjustment of the amount of water used for irrigation. It never takes into account the water stock in the soil or the state of root development.

The tensiometric technology used by Urbasense is coupled with meteorological data processing. It makes possible to provide the actual water requirement of the plantations, taking into account both weather conditions and the soil's water stock.

How do I know if this service is appropriate for my places?

The only key point : once a week, an agent must be available to reschedule the watering programmer (individual or centralized).
A technical agent (sports ground manager, for example) is also a real asset for the added value of the service.

I don't have an integrated watering system, is this service useful?

Yes, some collectivities are still forced to sprinkle places with manually installed devices. Two elements complete the water saving:
  • An assessment of the homogeneity of water supply, thanks to our two measuring points
  • A reduction in the time spent on watering

What is your feedback on the savings made?

For example, in 2016, in the Ile de France area, the theoretical need for a large playground was around 2,800 m³ (filtering field of honour).
The usual practices observed (3 times 20 min per sector each week) led to consumption of nearly 6,000 m³.

Generally, the water’s costs are close to tax. Savings for 2016 are 3,200m3 of water or approximatively 13,000 € HT/m3.

Warning : these volumes vary each year, depending on weather conditions. Only one thing is certain: you will only bring the water that is strictly necessary at the right time.

Understand the material : some details

What is the autonomy of your sensors?

It increases every months. Today it is between 18 to 24 months. In concrete terms, we carry out an annual maintenance that includes a change of batteries.

How your sensors communicate?

Several telecommunication technologies are used depending of the availibility of networks at each place : GSM, SigFox, LoRA. Wifi and bluetooth are not use today for practical and energy reasons.

Are your sensors guaranteed?

Yes. Our sensors are guarenteed for the contract duration when there are rented (global functioning guarantee). They are guaranteed two years when they are sold.

What is your perspective on the reliability of your sensors?

The first sensors were deployed at the end of 2014 and still operational on the ground. More broadly speaking, we assemble and test our stations and we keep control on the assembly line, it’s a critical point for sensors reliability.
