    DESCRIPTION

    Model IAP N 3000 IR

    Plant for the recovery of rainwater coming from the roofs of buildings in monolithic polyethylene ribbed model manufactured by interro built in the rotational moulding technique with constant thickness of the walls reinforced by vertical ribs. The recovered water can be reused for non-drinkable irrigation purposes.

    The plant includes: inlet and overflow PE pipe, self-cleaning leaf filter with removable stainless steel grid with filtering efficiency of 90% installed inside the tower, inlet decanter tube to avoid the turbulence of the possible laying formed in the bottom of the tank, pressurization pump and re-launch to the users and control unit of the system. The control unit, to be installed on a special room, is composed of: pressure gauge, pressure switch, volume expansion tank of 8 lt, non-return valve and electric control panel. In the tank there are inspection cap and flap lid with key closure.

    Function and use

    The system is suitable for the accumulation and recovery of rainwater coming exclusively from building roofs. The recovered water can be reused for watering plants, vegetable gardens, gardens and for washing vehicles. It is however mandatory to keep the uses of drinking water related to hygiene, body care and cooking fed by the public aqueduct. Every user used with recovery water must be indicated with a sign indicating “NON POTABLE WATER”. The control unit shall be installed in a special room near the storage tank.

     

    Standards and certifications

    Complies with the standards:

    • UNI EN 11445:2012
    • CAM (Minimum Environmental Criteria)
    • D.M. n. 63 of 10 March 2020
    • 2.2.8.2. Rainwater purification and reuse
    • 2.2.8.3. Public green irrigation network
    • 2.3.4. Water saving
    • Chapter. H management of public gardens: irrigation systems
    • Technical specifications point 2: water reuse

    Sizing

    The BIOBLU rainwater recovery system is easy to use and reduces to a minimum the consumption of mains water for all applications where rainwater can be used.

    For the sizing of the useful volume of the recovery tank, there are some calculation systems that include some variable data depending on the needs. The following describes a “standard system” for calculating the volume of the storage tank in accordance with UNI EN 11445.

    Parameters for calculating the volume

     

    Recoverable volume in one year:

    • Q = P x S x 0,9 (litres)
    • P = average annual rainfall in mm (Municipality);
    • S = sum of the catchment areas in sqm;
      0.9 = effectiveness of the leaf filter

     

    Volume of water to be recovered:

    • V = ab x 150 x 365 x R (litres)
    • Ab = No. of inhabitants;
    • 150 = average water consumption per ab/g;
    • R = % of water to be recovered

     

    Useful volume of the tank:

    • Vs = M x 21/365 (litres)
    • M = mean between Q and V;
    • 21 = average consecutive days without precipitation; 365 = days/year

    Accessories available and recommended

    • Extension cord PRO X 600
    • CHI Y 800-600 Telescopic Manhole Cover
    • GRI Y 600 anti-intrusion grid
    • Restoration kit aqueduct KIT ACQ 220

    MAINTENANCE OF RAINWATER RECOVERY SYSTEM

    Installation

    For installation, follow the instructions in our “handling, laying and use” manual.

    Goodwill

    Rainwater recovery plants have no need to start and are ready for use. Previously fill the tank with clean water and use it according to the purposes for which it was installed.

    Maintenance

    For rainwater recovery plants, the following operations shall be carried out at least every six months:

    • Check for deformation on the inner surface of the tank.
    • Check that no coarse bodies obstruct the inlets and exits of the tank and, if necessary, immediately remove them.
    • Check the effectiveness of the leaf filter and any clogging. Clean it clean it from leaves or branches stuck in the middle of the grid or clean it by jet of water pressure.
    • Check that an excessive layer of silt has not formed in the bottom of the storage tank and, if necessary, clean the tank with water jet cleaning and disinfection with sodium hypochlorite or other disinfectant.
    • Check the operation of the level probes and instrumentation supplied with the control unit (pressure gauge, pressure switch, solenoid valves, etc…)
    • Verify that the absorption of the pressurization pump is within the plate data of the equipment itself
    • Check the pressure of the expansion vessel and, if necessary, return it to the pressure plate

    For any other detailed information please refer to the specific user and maintenance booklet attached to the supply.
