Household hazardous waste day for Watertown residents

The Nov 15 event
The city page lists Thursday Oct 22 as passed and Sunday Nov 15 as remaining. It is open only to member towns: Arlington, Bedford, Belmont, Lexington, Lincoln, Waltham and Watertown. Stay in your vehicle, put items in the trunk (not the back seat), and bring ID. No fee is stated on the city page. The facility is closed in winter, so if you miss Nov 15 you wait until spring. Waltham's page lists the same facility with other details, including that registration can close at noon the Friday before or at 600 cars.
What to bring and what to leave
Typical items are oil-based paint, solvents, pesticides, antifreeze, gasoline, auto batteries and pool chemicals. Water-based (latex) paint is not accepted, and dried latex can go in the trash. Pack containers upright and sealed in a plastic tub so nothing rolls in the trunk. Keep products in the original labelled containers. Fluorescent bulbs and mercury items have a separate year-round option at the Watertown Recycle Center. Check each product against the facility's list before loading the car so you do not make the trip for nothing.
What a hauler cannot take
Paint, solvents and batteries do not belong in a hauler's load, so set them aside. If a garage cleanout turns up cans of old stain, set them aside before the crew arrives so the pickup price stays at the item rate. A quarter trailer is $209, which is a poor use of space for hazardous cans anyway. The city's own bulky pickup does not cover hazardous products either, so a garage with old cans needs this one trip. Registration is online, and residency proof is required.
