Infiltration System AquaCell
The infiltration system application was created in cooperation with Wavin Polska and Wavin Hungary. It allows the selection of infiltration tanks and horizontal infiltration pipes based on the DWA-A-138 guidelines. Depending on the surface of the area from which rainwater is collected and the type of soil, you receive the selection of an optimized infiltration system based on the adopted model of rain distribution. This means that the system is selected for the most critical parameters provided for given conditions.
Wavin AquaCell is a modular rainwater drainage system that can be used in both simple and reinforced (double) designs, thus covering the widest range of load-bearing requirements. It is suitable for treating rainwater in green areas, residential areas, parking lots and roads, as well as in commercial and industrial zones. Thanks to its stackable design, it takes up much less space on construction sites and can be transported more efficiently than other models. It can be inspected and cleaned via a test channel.
The selection of a rainwater drainage system depends on the terrain and soil type. It is also possible to adapt the system to the specific intensity and duration of rainfall, which allows for optimal rainwater treatment. The application uses an atlas available for 69 regions of Hungary based on data collected by 100 automatic measuring stations to obtain the size of the given drainage field. In Poland, the application uses the Polish Atlas of Design Rainfall Intensities PANDa. The atlas contains precise data from the last 30 years for a spatial resolution of 5 x 5 km.
As a result of the selection, you will receive a calculation that includes the number of required elements and data about the tank, such as its dimensions, water capacity and structure. In addition, it is possible to download DWG drawings and other materials for the given desiccant system.
The application is available in Poland and Hungary.
Calculating the size of the drainage system
For the selected type of investment and its parameters (length and width) and type of terrain, the application will select the best solution.
To perform the calculations, the following data will be required:
- infiltration coefficient [m/s],
- area of the reduced catchment area (calculated using the configurator),
- groundwater level,
- height of the tank’s ground cover.
Additionally, you should select a precipitation model that will be used to calculate the amount of precipitation water.
Dimensioning according to the DWA-A-138 guideline for a canalized catchment area ≤ 200ha or systems with a flow time of ≤ 15min.
Hungary Precipitation Intensity Atlas for 69 regions
Precipitation atlas based on the maximum precipitation intensity from the original precipitation time series recorded by HungaroMet between 2002-2023. It covers the precipitation duration range from 5 minutes to 5760 minutes (4 days). The maximum precipitation intensity is selected using the Peak Over Threshold (POT) method. The precipitation distribution is modeled with a 2-parameter exponential distribution. The built-in distribution data allows the estimation of the maximum precipitation intensity for durations from 5 minutes to 5760 minutes (4 days) and frequencies from 1 year to 100 years, for the entire territory of Hungary in 69 regions.
Rain intensities data PANDa
Polish Rainfall Atlas (PANDa) on a digital platform providing information on rainfall flows for all cities in Poland. PANDa offers current, indisputable rainfall data, which are subject to control over old models that do not reflect the permissible values of rainfall flows and have limitations to underestimate the results. The basis for the PANDa platform is current rainfall data from three decades, recorded using 100 rain gauges that meet the measurement standards adopted in Poland. Having real rainfall data allows for the assessment of future threats and planning of preventive measures. PANDa is also a tool necessary for the modern design of rainwater management systems, available 24/7.
Results of the selection of infiltration systems
Based on the information provided, the application will calculate:
- minimum tank volume based on the selected rainfall model,
- total inflow to the tank,
- total drain from the tank,
- tank emptying time.
The application will propose the number of AquaCell boxes needed to implement the selected solution based on calculations. Additionally, it is possible to download full documentation in PDF format.
When making calculations in the application, it is possible to contact the manufacturer directly and ask for an offer, price and details of the proposed solution.
