Barnstable Water Pollution Control Division

This was easily accessible. The RV dump location is well marked, just use the square hole under the blue handle. The rinse water was not able to be attached to our black tank flush.

We spent two months on Cape Cod during the COVID-19 stay in place orders. Four times we used this facility during that time and each time went off without a hitch. Dumping is free for campers and buses but be sure not to block the two ramps leading to the commercial dump slots.

Easy to back in with plenty of room on both sides. The only downside is there is no potable water here and the rinse water is a fireman's hose so be careful if you feel you must rinse out your hose, the water pressure will knock you over if you're not careful.
