Date may change

Come join us for our bi-annual children's AND ADULT clothing swap at the Hosmer Elementary School in Watertown! You do not have to bring any clothes to participate.

Sizes Newborn to 12, Maternity also accepted. No toys and baby gear, but accessories like shoes and paired socks are accepted.

Please bring spring / summer items only. No winter clothes until fall swap. Bring your own (BYO) bags. All clothes should be washed before donating.

Donation drop off starts 1 hour before event or drop off early at DPW.

If you help sort / fold clothes from 4PM, you get to pick the clothes first.

Enter through the cafeteria door, rather than from the main entrance of the elementary school.

This event is hosted with the generous support of DPW, and all remainders will be taken by Helpsy for recycling. You can drop off your clothing early at DPW at 124 Orchard Street starting from April 2, 2024 during the operating hours of 7:00 am to 3:30 pm.

Black Earth Soil Give Away & Baby Oak tree give away

Saturday, April 27, 2024 from 10AM-2PM
Event will be held at 124 Orchard St. The DPW office parking lot. Please bring a Watertown ID or proof of residency.

Watertown is offering free finished compost to residents. Black Earth’s finished compost was created using food scraps from Watertown residents. We are closing the circle and providing soil back to residents to use in backyards and gardens. This is open to all residents, even if they are not enrolled in the food scrap collection program. Please bring your own buckets and shovel to take soil away in. Initial limit of 10 gallons (2 five-gallon buckets per person). Available while supplies last at the event. Come early if you are very interested in getting soil!

The forestry department will be giving away baby oak trees for residents to plant on their own property. These will be the responsibility of the resident to water and care for. The City will not be providing any additional support for tree care, and the tree must be planted on non-city property. Trees are available while supplies last. One tree per household.

Paper Shredding 

Watertown is partnering with Shred-it, to securely shred confidential papers. All shredded paper will be recycled with Stericycle. Please only bring documents that are confidential—other paper materials should be placed in your curbside recycle bin. If materials are already pre-shredded, please place in a paper bag.

  • Shred-it can accept papers with staples in them.
  • Materials should be placed in paper bags or brought in boxes. The boxes will be returned.
  • Materials will be shredded on site.

Styrofoam Recycling 

Watertown is partnering with Save That Stuff to recycle Styrofoam. Please collect and save any Styrofoam you have for this event. Styrofoam CANNOT go into curbside recycling totes.

  • They only accept rigid white Styrofoam
  • If it SNAPS when you break it, it is the correct type
  • NO packing peanuts or take out containers


Watertown is partnering with Mass Save to recycle old and energy inefficient dehumidifiers.
