Sib, my bog garden has running water, and works just fine. Water flow does not have to be great, just moving, and the plants will benefit by having oxygen drawn into the soil, helping to prevent root rot, and other similar problems caused by standing water. I have had my bog garden pumping merrily away for 15 years, without any problems. I have s. flava "Marston Dwarf", s. leucophylla "Schnells Ghost", S.r. gulfensis "stocky form" Yellow River, Fla., and one natural hybrid growing in it along with almost all of my VFT's. Pings are in there, along with droseras anglica, capillaris, intermedia "Carolina Giant", and brevifolia. Since where they live in a bog, the water is slow moving beneath the soil, they have no problem accepting this condition as home. And will grow in a very healthy way. I only have to sweat cut worm.
