UNDERGROUND POLYETHYLENE TANK WITH PUMP

Model IAP MM 10000 ID

Plant for the recovery of rainwater coming from the roofs of buildings in modular polyethylene polyethylene medium modular model from interrogation built in the technique of rotational molding to constant thickness of the walls reinforced by vertical ribs with modules a total passage welded by electrofusion. The recovered water can be reused for non-drinkable purposes for the flushing of WC boxes or for irrigation of the green.

The system consists of inlet and overflow PE pipes, self-cleaning leaf filter with removable stainless steel grid with filtering efficiency of 90% installed inside the turret, inlet decanter tube to avoid the turbulence of any laying formed in the bottom of the tank, service tank with unidirectional valve, pressurization pump and throttle to the users and control unit of the system. The control unit to be installed on a special room is composed of: manometer, pressure switch, expansion tank volume of 8 liters, non-return valve, water supply solenoid valve, solenoid valve inhibition irrigation line in case of lack of rainwater in the tank, manual disinfection system of the tank with internal recirculation of the tank and electric control panel. In the tank there are inspection caps and flap lids with key closure.

 

Standard configuration of the product

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 the supply of the WC boxes of the building, the watering of plants, vegetable gardens, gardens, for the washing of vehicles and for all uses where it does not need the use of drinking water.

It is equipped with a service tank with a volume of 30 liters with unidirectional valve in which is installed the single-phase pressurization pump and piping for the refilling.

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 useful volume of the tank

Volume recoverable in one year:

• Q = P x S x 0.9 (litres)
• P = average annual rainfall in mm (Municipality);
• S = sum of the collecting surfaces in m2;
• 0.9 = effectiveness of the leaf filter

Volume of water to recover:

• V = ab x 150 x 365 x R (litres)
• Ab = n. of the people living there;
• 150 = average water consumption per inhabitant/d;
• R = % of water that is intended to be recovered

Useful tank volume:

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

 

Accessories available and recommended

• Extension cord
• Telescopic Manhole Cover
• Anti-intrusion grid

 

Electromechanical components

Control unit

 

Maintenance of hydraulic rainwater recovery system

Installation

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

To start

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.

In case of stagnant water and with an unpleasant smell, it is possible to clean the tank by recirculating the water through the proportional dispenser of disinfectant by acting on the appropriate valve. Recirculate the water inside the tank for a few minutes until the smells disappear. Wait at least two hours before its reuse. The WC cisterns can be fed immediately after reclamation.

• If an excessive layer of silt has formed at the bottom of the storage tank, clean the tank with a pressure water jet and disinfect with sodium hypochlorite or other disinfectant.
• Check and, if necessary, clean the sieve filter installed on the delivery of the primary services (WC cisterns supply).
• 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.

 

Certificate of compliance with rainwater recovery system

The rainwater recovery plants Di Camillo Tanks are used for the collection of runoff rainwater coming exclusively from the roofs of buildings to supply services that do not require drinking water as indicated in the product data sheets (STC 01).

They are made of polyethylene, through the system of “rotational molding” and comply with the requirements of the following 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

 

Purification yields

The plant at full capacity returns water in accordance with national standards required for its reuse for non-drinking purposes. Every user used with recovery water must be indicated with a sign indicating: “NON POTABLE WATER”.

Final delivery of the discharge

Reuse for non-drinkable purposes

Warnings

Clean the container of any processing residues present or formed.

Temperature of use of the liquids contained on the tanks -20 ¿C +60 ¿C, we recommend not to exceed 50 ¿C.

Please note that the performance of the tank Di Camillo Tanks depend on the development of the entire rainwater recovery system, the characteristics of the inlet water compatible with polyethylene and the parameters used for its sizing reported in the product data sheets; the relative state of use, its installation and regular periodic maintenance.

We recommend to check the suitability of the Di Camillo Serbatoi plant, where necessary, with the competent body of the territory, since there are substantial differences in the solutions accepted by local authorities that could enact different and more restrictive provisions in compliance with local regulations.

The plant solutions suggested by Di Camillo Serbatoi do not replace as role and function neither the competent Technician nor the Authority which is responsible for the authorization release.

Di Camillo Serbatoi declines all responsibility whenever the correct choice of plant solution is not performed authorized by the competent authority, the correct procedure of management of the depurative process and the inadequate use of the equipment and manufactured parts of the plant itself.

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