    Model CLY 7000 P 220

    Polyethylene tank, coloured in mass, protected by the action of ultraviolet rays for the storage of not particularly aggressive liquids, built in the rotational moulding technique with constant wall thickness, of the panettone type.

    The tank is equipped with 400 female bayonet cap with a watertight seal and breather so the tanks are never subjected to pressure that deviates significantly from the hydrostatic pressure and operate at atmospheric pressure. They are included in endowment nr. 3 non toxic brass inserts, ribbed, with 1″ diameter female thread for possible connection of pipes, valves or filling and/or emptying of the tank with relative o-ring placed on the inner part of the closure cap at the vent thread.


    Standard configuration of the product

    Function and use

    Container to be used outside for the containment of liquids compatible with polyethylene.

    The tank can be used for the storage of: rainwater, rainwater, accumulations for fire fighting, domestic waste water, landfill leachate, drinking water, etc. The positioning of outdoor containers shall be done on a flat, uniform, horizontal surface (maximum gradient 4 ) and of a width equal to or greater than the base of the container. The external operating temperature range is 20 ºC +60 ºC. However, we recommend not to exceed 50 ºC. The tanks can be drilled at the flat parts for inserting pipes or fittings.



    The dimensioning of the external tanks was carried out considering the containment of liquids with ρ = 1000 kg/m3. For higher densities we suggest not to fill the tank completely but the dimensional stability is not assured. The average wall thickness is made in relation to the volume and shape of the tank.


    Accessories available and recommended

    • Lip seal
    • Overflow hose
    • Wall connection




    For installation follow the instructions in our manual “Laying and Handling”.

    Place the tank on a smooth and clean flat surface (max slope 4 ) and distance it at least 10 cm from walls and obstacles.

    Do not bury the tank, USE ONLY OUTSIDE.

    Use and maintenance

    The tanks are usually supplied without having undergone any internal and external treatment (washing etc…).

    It is therefore necessary to carry out at least one internal wash with water and detergents or soaps specific to the type of use where necessary.

    Finally, rinse thoroughly with drinking water.

    For storage tanks, the following operations shall be carried out at least annually:

    • Check that the bottom of the storage tank has not formed an excessive layer of silt and eventually clear the tank with water jet cleaning and disinfection with sodium hypochlorite.
    • Check the effectiveness of any loading and/or unloading nozzles inserted on the flat parts of the same.
    • Check for deformation on the surface of the container at least 48 hours after filling.

    For all maintenance and operation of the system see the manual.


    External blue tank certificate of conformity

    Outdoor tanks are used for the containment and storage of rainwater, rain water, domestic waste water, drinking water, landfill leachate and all liquids compatible with polyethylene at atmospheric pressure as indicated in the product data sheets (STC 01).

    They are made of polyethylene by means of the “rotational moulding” system and comply with the requirements of the following Standards:

    • Regulation No. 1935/2004 EC
    • EU Regulation 2023/2006
    • EU Regulation 10/2011 EU Regulation 213/2018 D.P.R. 777/82 and s.m.i.
    • D.M. 21/03/73 and s.m.i.
    • D.M. n 174 of 06/04/2004 and s.m.i.


    Suitability for food contact according to Directives 95/31/EC and 96/77/EC

    The blue PE material used for the manufacture of the container shall comply with the overall and specific migration limits and the specific restrictions of the test conditions of the IIP accredited laboratory where the analyses are performed and attested in the IIP TEST REPORT -TEST REPORT No. 0821LP/2021 of 20/10/2021 visible in the Company.


    • perform the positioning of the tank on a smooth and clean flat surface (max slope 4 ) and spaced at least 10 cm from walls and obstacles.
    • Do not bury the tank, USE ONLY OUTSIDE.


    External operating temperature -20 C +60 C, we recommend not to exceed 50 ¿C.

    Before filling the tank with substances other than water, carefully check the compatibility of PE with the main chemicals, indicated in the table of “compatibility chemicals” and possibly contact the Technical Office of Di Camillo Tanks. The dimensioning of the tank is calculated for the containment of liquids with ρ = 1000 kg/m3, do not exceed this value. The inspection or loading cap is of the type bayonet watertight watertight, with vent: make sure that it works properly during the loading and emptying of the tank. Clean the container of any processing residues present or formed.  Di Camillo Serbatoi declines any responsibility inherent to Title V of D. Lgs. 152/06 every time the correct choice of plant solution authorized by the competent authority is not performed, the correct procedure of tank management and the inadequate use of the product.

    For the correct installation procedures management and maintenance, please refer to what is indicated in the special booklets attached to the supply.
