16-1125 v3.0/The Living House/Grey Water System and the Red List

QUESTION

We are looking to use the Alo Aqua/Intewa Grey Water treatment system on this project and would like some clarity around which individual components of this system we would need to track for Red List compliance. The Alo Aqua/Intewa system is a proprietary system comprised of 4 basic parts.These being the (i) Electronic control unit (ii) Blower (iii) Bio reactor and (iv) clear water tank (please refer to picture Alo Aqua2).

We have read previous dialogues and exceptions and would like to confirm that the following approach is appropriate (please refer to image Alo Aqua for numbering):

(i) 11 &12.Elecronic control unit - Does not need to be tracked under Exception I10-E2 5/2013 Small Electrical Components.

(ii) 10.Blower - Housing and major components require supporting data. Small mechanical components do not need to be tracked as per I10-E3 4/2010 Small Mechanical Components exception.

(iii) Bio Reactor - Items requiring supporting data 1.Bioreactor tank, 2. Wheel weight,  3. Membrane, 7. Back flush tank, 8.Prefilter, 9. Bioreactor inflow, 13. Bioreactor emergency overflow.

Item 6. Float switch does not require tracking as per I10-E3 4/2010 Small Mechanical Components exception.

Items 4. Suction Pump, 5. Back flush pump do not require tracking as they are pumps that are an integral part of the bio reactor. 

(iv) Clear Water Tank - 17.Clear Water tank, 14. Clear water inflow 15. Clear water tank emergency overflow 19. Clear Water suction. 

Items 16 & 18. Float switches do not require tracking as per I10-E3 4/2010 Small Mechanical Components exception. 

The following installation materials and used to configure the above items and we would need to provide supporting data for all of these items:

  • 2pcs. Pipe Ø110 mm x 250mm, 
  • Installation lubricant 
  • Siphon hose 1“ 
  • 5 pc cable ducts PG 11 with nut 
  • ½“ clear water hose, 2 m
  • 5 x cable glant
  • 1“ external aerator hose, 2 m
  • 1“ internal aerator hose, 0,6 m
  • ½“ suction unit
  • Is this correct?

    ANSWER

    (i) Based on I10-E2 Small Electrical Components, the electronic control unit does not need to be tracked for Red List compliance, but it must meet the RoHS Directive.

    (ii) Based on I10-E3 Small Mechanical Components, the housing and major components for the blower must be tracked for Red List compliance, but the small mechanical components do not need to be tracked. Any electrical components in the blower must also meet the RoHS Directive.
    (iii) All major components of the bioreactor must be tracked. This includes the bioreactor tank, wheel weight, membrane, back flush tank, prefilter, bioreactor inflow, bioreactor emergency overflow, and any other components that are not eligible for exclusion under I10-E3. The float switch does not need to be tracked (I10-E3). The major components of both the suction pump and back flush pump need to be tracked, and the electrical components in the pumps must be RoHS compliant.
    (iv) All major components of the clear water tank must be tracked. This includes the clear water tank, clear water inflow, clear water tank emergency overflow, clear water suction, and any other components that are not eligible for exclusion under I10-E3. The float switches do not need to be tracked (I10-E3).
    You are correct that all installation materials in the bulleted list above must be tracked.
