The larger sewage tank I have now in the darkroom trailer is far too heavy to roll out and dump. The tank when loaded down with water is upwards of 200lbs. To ease the work load I have set up a pump system. This is the first time I have used it. I can now dump the waste water safely and efficiently in the proper environmental dump stations around the country.
I plan to also use the pump to refresh my working water tanks in the field as necessary. I can draw water out of streams etc in remote locations around Canada, allowing me to continue the wet plate picture making.
