Frequently Asked Questions

How do dump stations work?

Dump stations have a drain cap that covers the sewer and drain outlet. You need to close the valve on the tank, take the cap off the sewer and push the hose from your tank into the outlet. Once you turn the valve, the tank will empty the blackwater.

How often should you empty the tank?

You should empty the tank when it reaches 2/3 capacity. If it goes any higher, it can overflow.

Do RV dump stations charge?

Dump stations generally charge users for their services. Some campground stations offer this service for free if you spend the night there.

What is a RV dump station?

A RV dump station is a facility that lets you empty your holding tanks without getting your hands dirty. It also uses sanitary methods to dispose of the waste.

Bear Brook State Park

The park began life in 1935 when the Civilian Conservation Corps took the original 6,000 acres, laid out what was to become the park, and built the original structures, of which several remain. The state took over Bear Brook State Park when the CCC disbanded in 1942. Over the years, more land area was added to the park, and today, it spans more than 10,000 acres. Today, too, there is a museum in the park that features the Civilian Conservation Corps. Read more
