Has anybody seen a statistic on how much black water is produced per person per day? This would help me determine when I need to pump out my holding tank. Thanks. <<<Gary Ritzman>>> M/V Dharma Albin 40 Mercer Island WA

Better yet, install a tank monitor. We use the SCAD tank monitors on both of our holding tanks and they work well. Easy to install as long as you have access to a non-metalic tank. https://www.emarineinc.com/SCAD-SOLO-Tank-Monitor-System There are other options using the same system for metalic (heaven forbid) tanks. FWIW, I think you'll get answers all over the place. A lot depends on frequency, how much fresh/raw water is pumped through in the process, etc. <><><><><><><><><><><><>Mozilla Thunderbird<><><><><><><><><><> Bob McLeran and Judy Young Manatee Cove Marina MV Sanderling Patrick Air Force Base DeFever 41 Trawler for sale Melbourne, Florida Blog: http://mvsanderling.net/Blog Web: http://cruising.mvsanderling.net/ Site: http://Ourphotos.hopto.org Site: http://SanderlingBlog.hopto.org On 7/16/2020 12:18 PM, Gary Ritzman via Trawlers-and-Trawlering wrote: > Has anybody seen a statistic on how much black water is produced per person per day?
