Charleston Waterkeeper is proud to offer a mobile pumpout service in the lower Charleston Harbor. Our pumpout boat, the Number 2, will come to your slip or location at anchorage and pump out your onboard sanitary waste holding tank. The Mobile Pumpout Program provides boaters with a free, convenient, and legal way to dispose of sewage from sanitary waste tanks.

How It Works
To request a pumpout call please complete the following form: Pumpout Request Form. Pumpouts are performed once per week on weekends. All requests for pumpout service must be received by 5 pm on Friday.
After we complete your pumpout, we will send you an email confirming your pumpout was completed. If you have any questions, please call (843) 608-9287.
Boat owners do not need to be present and there is no charge for pumpout service.
When the Number 2’s holding tank is full, we pump out at the City Marina’s shoreside pumpout station. From there the sewage is sent to Charleston Water System’s Plum Island sewage treatment plant for proper treatment.
To Request a Pumpout:
Gallons of Marine Sewage Diverted from Charleston's Waterways
Simply put, it is the right thing to do! Discharging untreated sewage into Charleston’s Waterways is illegal. Even most marine head systems provide only a minimal level of treatment for sanitary waste. For example, treated discharges from US Coast Guard approved Type I and Type II marine sanitation devices still exceed South Carolina’s water quality standards for safe swimming and shellfish harvesting. Untreated and minimally treated sewage discharges from boats jeopardize our ability to safely swim and harvest shellfish from our local waterways. Using Charleston Waterkeeper’s mobile pumpout service is a great way to help protect Charleston’s waterways!
Proper disposal of marine sewage is only one way boaters can help protect Charleston’s waterways. Learn about other responsible boating practices in Charleston County’s Recreational Boater Education Booklet.
Captain Meredith Lewis
Captain Meredith Lewis joined Charleston Waterkeeper in June of 2020 to captain the Number 2. Meredith holds a 25 ton United States Coast Guard Master Captain’s License. Over the last several years she has logged hundreds of hours on various vessels including several luxury yachts. Hailing from Salisbury, Maryland, a town settled to be an outpost for Lord Baltimore in 1732, because it was the only navigable waterway leading to the Chesapeake Bay, Meredith was destined to love the water. She has spent most of her life on and around boats with her family. She is proud to continue that tradition with Charleston Waterkeeper and contribute to the conservation of Charleston’s local waterways.
