Harwich household hazardous waste days

Folding tables and boxes of paint cans, garden chemical jugs and cleaning bottles at a town transfer station on Cape Cod

How the 2026 season worked

The town page says collections are held the second Saturday of each month May through October from 9:00 AM to Noon, at the Harwich Transfer Station, 209 Queen Anne Road The 2026 dates were May 9, June 13, July 11, August 8, September 12 and October 10.

The county runs it. Harwich is a regional program with Brewster and Chatham, and residents of all three use the Harwich site. Town residents participate for free; proof of residency is required; non-residents must register in advance on the county website. Small businesses register at least two weeks ahead with the county.

What the county takes and refuses

For Harwich the county lists paints, lawn chemicals, cleaners, auto fluids, pool chemicals and mercury items, and under not accepted, unknown materials and medical waste. The county's general list also turns away propane tanks, gas cylinders, empty aerosol cans, fire extinguishers, smoke detectors and batteries.

Latex paint is not hazardous waste, says the county. For everyday needs the Transfer Station has an auto shed for car batteries, motor oil, filters, gasoline and antifreeze and sheds for paint and oil. A propane tank goes to the station at the $5 line, not to the county.

Winter and what to do until spring

The county says, "The 2027 collection schedule and updated town brochures will be posted in spring 2027" The town's wording suggests second Saturdays again, but the town has not posted 2027 dates, so do not plan on specific days.

From November through April the county collection is closed. Keep cans labeled and upright, store them out of the weather, and do not pour anything down a drain or onto the ground. Dumping hazardous waste in Harwich draws a $300 fine under Chapter 247.

JUNKRUN does not haul hazardous products. It can take the furniture, boxes and appliances around them, from $159.
