You can call your local waste management to see what they recommend. Generally, at least in our town, there is no problem washing excess paint off the rollers and brushes down the sink as the water gets treated. The precaution on the MSDS is not to wash in an area that will not treat the water such as storm sewers or on the ground. We recommend that you first remove most of the excess paint on a piece of cardboard and let it dry, then dispose in the trash. Once you do that, there will be very little paint left on the brush or roller.
