Pesticides are safe and effective, used routinely in the home
and workplace. Most people are generally aware of their hazards.
But they can also ultimately cost many more times their purchase price
if disposed of incorrectly.
Because pesticides can harm the environment, it is natural, but
totally incorrect to think it is safer to flush them down
the drain.
Pesticides are made to be safe in the environment if used as
directed, but are not safe in a sewer system. If allowed to enter
the system, pesticides lead to very expensive equipment and process
changes that the sewer system user must pay for through higher rates.
The "organophosphate" pesticides which include Diazinon, Dursban and
Malathion, generate the most problems.
While use of organic pesticides is increasing, the use of
organophosphates is still common. CCMA stresses the importance of
keeping all pesticides out of drains that lead to the sewer system.
As little as two ounces, or one-quarter cup of Diazinon, makes it
impossible for CCMA to comply with required water treatment standards.
Whether in liquid or dry form, even with very small amounts, a few rules
always apply when using pesticides:
- Never pour any pesticide solution down a drain, or clean
containers or equipment in a sink
- Mix only the amount and strength required and use organic
substances if possible
- Always mix, rinse, clean up and drain excess solutions outside on
the ground or yard
Pesticides only enter a sewer system through the drains of
system users. Therefore, system users are the only ones who can prevent
this contamination and resulting expensive corrective measures.

Of additional concern to the environment, is proper disposal of
prescription drugs. The FDA advises that the label or accompanying
patient information for individual prescription drugs be referenced to
determine if safe to dispose into the sewer system.
