Treatment using storage basins
 
rain water treatment system series IPP/AA | IPP/AM
rain water treatment system series IPP/AA | IPP/AM
EURO MEC’s rain water treatment system, series IPP/AA and IPP/AM, is used for medium and large sized surface areas  where it diverts and holds rain water in retention basins to be later pumped, with a restricted flow, into public drainage systems within approximately 48 hours according to relevant norms.

Downstream from these rain water basins, series IPP/AA and IPP/AM, oil separators with or without coalescence filters and dimensioned according to the norm EN 858-1 can be installed.
These rain water systems, series IPP/AA, consist of circular prefabricated basins constructed with reinforced concrete circular rings in reinforced concrete with carriageable covering slabs and cast iron manhole covers class D400 or series IPP/AM monoblocs which are prefabricated or cast on-site using reinforced concrete.

First rain water treatment plants type EURO MEC IPP/AA series are designed in compliance with the Norms prescriptions in force.
Their correct use allows the reduction of the ground water pollution and impoverishment, because they convey the meteoric water into the sewers or on site after separating the first rain water, which is collected into suitable storage basins. The stored water is subsequently pumped out of the basin with a constant and limited flow rate during 48 hours, in accordance with the current laws, towards the sewers or the final treatment plant.

Optional oil separators can be located forward the first rain water treatment plant type EURO MEC IPP/AA series. Such separators are dimensioned according to the equalized flow rate and DIN 1999 regulations as well as equipped with a coalescence filter.
First rain water treatment plants type EURO MEC IPP/AA series are composed of highly resistant reinforced concrete modular rings circular tanks.
The cover is carriageable and complete with D400 cast iron inspection manholes.

HOW FIRST RAIN WATER TREATMENT PLANTS FOR SURFACES FROM 4000 TO 10.000 SQM WITH MODULAR RINGS IPP/AA SERIES AND FROM 4.000 TO 30.000 SQM IPP/AM SERIES WORK
The first rain water is conveyed into the installations type EURO MEC IPP/AA series and therefore drained into the controlled flow sewers network.
The first rain water volume evacuation must be carried out according to the current laws, during a minimal time of 48 hours between a meteoric event and another.

An electronic device detects when a precipitation begins and when the tank is subsequently filled up, memorizing this datum and activating the controlled flow rate lifting pump after a given programmable time.
When the basin reaches the maximum level equal to the polluted first rain water discharged volume a particular device stops pouring water into the tank and sends the subsequent diluted water into a water dispersion shaft or a superficial water stream.

The stored sewage is evacuated by means of a lifting pump with electrically controlled constant flow rate.
The sewage water can undergo an oil separation treatment with or without coalescence filters or chemical/physical installation before being sent into the sewers or centralized depuration plant.

USED MATERIALS
Tanks : highly resistant reinforced vibrated concrete
Shafts : class D400 cast iron
