RainWater Management

Infiltration and Attenuation Systems

The DRAIN­MAX Tun­nel trench can be used for a mul­ti­tude of ap­pli­ca­tions. To eas­ily achieve this, the sys­tem can be ex­tended to al­most any size by adding fur­ther tun­nels or rows.
The most im­por­tant ex­am­ples for pos­si­ble sys­tem lay­outs can be seen under:

Save heavy rain­fall and in­fil­trate it in the same lo­ca­tion.
For the in­fil­tra­tion of rain­wa­ter from sealed sur­faces, there are a num­ber of dif­fer­ent pos­si­bil­i­ties. IN­TEWA of­fers you com­plete so­lu­tions for trench and trough in­fil­tra­tion.

Save heavy rain­fall and throt­tle the runoff, if in­fil­tra­tion into the ground is not pos­si­ble.
Rain­wa­ter re­ten­tion is nec­es­sary if the in­tro­duc­tion of runoff into the pub­lic util­ity is re­stricted. De­pen­dent on the re­stric­tion, a nec­es­sary re­ten­tion vol­ume is cal­cu­lated in order to tem­porar­ily store heavy rain­fall events on th spot. This nec­es­sary buffer vol­ume can be stored above ground, as in a basin, or un­der­ground.

De­cen­tral­ized in­fil­tra­tion of treated waste­water in ac­cor­dance to DIN-Tech­ni­cal Re­port CEN/TR 12566-2 und  DIN 4261 eg. from a sep­tic sys­tem.
