TYPE A & B BASINS – WHAT ARE THEY?
Type A have a
decant structure
Type B do not
TYPE A & B BASINS – WHAT ARE THEY?
Need a dosing unit
Need a forebay & level spreader
Type A need a decanting outlet
Need inflows to the forebay only
TYPE A & B BASINS – WHAT ARE THEY?
Source: O2 Environment + Engineering
TYPE A & B BASINS – WHY USE THEM?
…..We need a control to
manage fine sediment
(and the nutrients, heavy
metals etc. that like to attach
themselves to such particles)
TYPE A & B BASINS – WHY USE THEM?
Automated dosing during rainfall events allows Type A and B basins to operate
in a flow-through manner, rather than a capture, treat and release approach.
This allows large and consecutive rainfall events to be treated more effectively
than Type D basins
TYPE A & B BASINS – WHY USE THEM?
Enhanced Sediment removal
Can retain water for site use
Reduced labour
Can remove need for pumps to discharge
Treatment occurs when you’re not on site (automated)
More focus placed on design and management by trained
personnel with an adaptive management approach

LEARNINGS TO DATE
WE CAN HANDLE LARGER EVENTS
Over 3x Type D design event for location
Over 2x design flow rate for Type B basin
All discharges below 50mg/L
SOIL TYPE AND PROFILES CHANGE!
Only determining the dose rate at the start of a
project can cause poor performance as site
conditions change
Regular jar testing should be done with milestones
on different stages of the project which expose
different soil profiles and type (e.g topsoil vs
subsoil vs imported fill). It is quick and easy to do
If in doubt – test the water or soil.
INCORRECT DOSE RATES
So many contractors indicate a product doesn’t
work. This is typically incorrect as they have either
underdosed or overdosed the product.
Generally you will be able to get most products to
work, some will just perform better..
Jar Testing is Important!
LEARN FROM EVERY EVENT!
You will not always get it right and adaptive
management is critical
Learn from every event with the tools provided and
improve your basins performance.
We have 20+ years to catch up on the Kiwis and it
will take time to educate, gain this knowledge and
shift the culture.
