3000 LITERS UNDERGROUND WATER TANK

Model SEI N 3000 AG

Polyethylene tank modular model to be interrogated for the storage of not particularly aggressive liquids, built in the rotational moulding technique with constant wall thickness.

The tank has a structure reinforced by vertical and horizontal ribs and is equipped with bayonet inspection caps male flap and waterproof seal not watertight and vent. The tank is suitable to operate only at atmospheric pressure.

 

Standard configuration of the product

Function and use

Container to be used underground for the storage of rainwater, rain water, accumulations for fire fighting, domestic waste water, landfill leachate, drinking water, etc.

The positioning of the tanks shall be carried out on a flat, uniform, horizontal excavation with a width greater than the base of the shell at least 30 cm.

The outdoor operating temperature range is 20 ºF C +60 ºF. However, we recommend not to exceed 50 ºF.

The tanks can be drilled at the flat parts for inserting pipes or fittings.

 

Sizing

The dimensioning of the interrupt tanks was carried out by verifying the mechanical strength of the geometry, when it is subjected to the working conditions. The structural analysis of the geometries was carried out by the creation of a finite element calculation model and by the experimental crushing tests carried out on the finished product. The tank has therefore been dimensioned to withstand a maximum covering load with vegetable soil not exceeding 40 cm.

 

Accessories available and recommended

• Extension cord
• Telescopic manhole cover
• Lip seal
• Anti-intrusion grid
• Overflow hose

 

Maintenance underground tank

Installation

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

Use and maintenance

The tanks are usually supplied without having undergone any internal and external treatment (washing etc…). It is therefore necessary to provide at least an internal washing 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 inner surface of the tank.

 

Certification of underground tank

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

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

• Regulation No. 1935/2004 EC
  
• Directive 2002/72/EC 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
  

 

Suitability for containing drinking water

• ARPAM report n 45/VR/14 of 29/10/2014
  
• ARPAM report n 46/VR/14 of 29/10/20149/10/2014

 

Warnings

External service temperature -20 C +60 C, we recommend not to exceed the 50 ºC.

Carefully check the compatibility of the EP with the main chemicals, indicated in the table of “compatibility chemicals” and contact the technical office if necessary.

The dimensioning of the tank to be interrupted is calculated to bear a maximum load of covering with soil, equal to 40 cm (pedonability).

Always ensure that you have connected the vent before loading and emptying the tank and check that the inspection lids are properly closed. The male bayonet cap and the watertight flap cap must be closed immediately after filling the tank.

Clean the container of any processing residues present or formed.

Important

• perform the positioning of the tank on a flat surface and carefully follow the instructions of the handling and installation booklet attached to the supply.
• Do not place the tank outside USE ONLY UNDERGROUND.
