Peter Caldwell – Ro ot ca use a n d d riv e rs
An interdisciplinary team was set up to determine if a
generic dosing product package could be developed
Solu tion
29 schemes over AMP5 are due to be installed from
5m3 to 30m3 storage size of ferric, with the same
Wastewater Non-Infrastructure for ortho or ferric or other materials dosing :-
Root cause :- Carbon was not directly considered for
basic control philosophies applied.
This product is an update of the AMP4 product, but
the original product. Can embodied carbon reduction with design reduced to the minimum required to
be achieved? achieve the plant requirements.
Driver :- Reduced embodied carbon

Greatest carbon reductions.
Product reduced from 2 tanks and large kiosk to single self bunded tank and small kiosk.
Smaller base and ancillaries for installation required.
Still full assembly of units off site and simple installation
Detail of any other particularly sustainability activity undertaken on the project.
Smaller systems will be much easier to install on small sites with difficult access
Tichatonga Mhlanga – Supplier may also be useful for other products / applications

Designers use a four stage hierarchy at the start of the project
Build
nothing
Build less,
Build clever
Build with lower carbon materials
Build more efficiently
