Chemical Supply

This Local Buy arrangement is available for use by councils in both Queensland and Tasmania and has been grouped into four categories including:

• Water and Waste Treatment Chemicals
• Agricultural chemicals and ;
• Chemical hardware and technology;
• Chemical testing, training and compliance

Potable water treatment is required for the health and aesthetic quality of the water supply. Chemical products may be required for coagulation, flocculation, disinfection, absorption, fluoridation but are not limited to these.

Sewage treatment is the process of removing contaminants from . It includes physical, chemical and biological processes to remove contaminants and produce environmentally safe treated (treated effluent).

Herbicides are chemical substances used to kill or control the growth of undesired plants such as weeds. These include but are not limited to non-selective, pre‐emergents and broad leaf weed. Active ingredients may vary according to the targeted plant.

Insecticides are chemical substances used to kill or control undesirable insects at various stages of the life cycle. The active ingredients may vary according to the targeted insect.

Pesticides are chemical substances or devices used to kill or control undesirable pests such as birds or rodents. The active ingredients or device may vary according to the targeted pest.

Fungicides are chemical substances used to kill or control undesirable fungi or fungal spores. The active ingredients may include sulphur and other ingredients depending on the targeted fungus.

are growth enhancers that promote or regulate plant growth. 

Adjuvants are substances added to modify a pesticide’s or fungicide’s performance, the physical properties of the spray mixture or both.
