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.
