Rain water diverters, rain water treatment plants and equipment, Rain water treatment plants and equipment, EURO MEC rain water diverters SSP series are used as established by L. R. n.26 of the Lombardy Region on 12.12.03 and are necessary to control inlet water sent to the drainage system. This allows to dispose them through ground natural infiltration without polluting ground water, separating rain water sent to the drainage system or to the treatment plant. standard plants, groundwater protection

According to the 91/271/CEE Directive EURO MEC monobloc, parallelepiped, rain water diverters, series SSP, stop potentially polluted rain water from seeping or flowing into the ground or waterways by separating the first rain water (the first 5 mm of each precipitation, equal to 50 mc/h) and diverting it either into the sewerage network or a treatment plant while the cleaner rain water is allowed to drain naturally into the ground.
  • Monobloc prefabbricated, parallelpiped rain water diverters in reinforced concrete (series SSP).
  • Cylindrical monobloc prefabbricated rain water diverters in reinforced concrete (series SSP/A).


WHAT MONOBLOC PARALLELEPIPED AND MONOBLOC CYLINDRICAL FIRST RAIN WATER DIVIDING PLANTS SSP - SSP/A SERIES ARE
Monobloc parallelepiped first rain water dividing plants type EURO MEC SSP series are used to limit the pollution and impoverishment of the underground water resources, thanks to the first rain water treatment. They are composed of a monobloc highly resistant reinforced concrete parallelepiped tank ensuring a total leak absence and the absence of ground infiltrations, a carriageable cover and concrete inspection shafts.

The installation can be located also in presence of ground water. Monobloc parallelepiped first rain water dividing plants type EURO MEC SSP series are necessary to control the water coming into the drainage system, because they allow its drainage through the natural filtering into the ground by separating the first rain water for the drainage system or for the depuration plant, without pollution for the ground water.

According to the Directive 91/271/CEE we consider first rain water the water corresponding to the first 5 mm of each precipitation (equal to 50 mc/h) evenly distributed on the total draining area treated by the draining network. In order to calculate such flow rates it has been established that this data can be obtained in 15 minutes.
The following afflux coefficients have been considered: 1 for covered/paved/waterproofed surfaces, and 0,3 for every kind of permeable surface except for cultivated areas.

HOW MONOBLOC PARALLELEPIPED FIRST RAIN WATER DIVIDING PLANTS SSP - SSP/A SERIES WORK
First rain water is pollutant because it contains sand, oils and hydrocarbons and therefore it is separated from the subsequent water (with no relevant pollution) by a calibrated overflow pipe “cipolletti” type designed according to the udometric coefficient comparing the “hourly afflux coefficient” (which considers a 15 minutes rain precipitation in the tank area) with the “delay coefficient” (which considers the basin area as well as the tank/network slope)

USED MATERIALS
Tanks : highly resistant reinforced vibrated concrete
Shafts : concrete (by request: class D400 cast iron)

SPECIFICATION
“Supply of a monobloc parallelepiped water dividing plant for first rain water type EURO MEC SSP series made of highly resistant reinforced concrete, with carriageable cover, concrete manholes and dimensioned with internal overflow pipe type “cipolletti”. “
