After having so much success with surge buckets on our previous upgrade we decided to take it to the next level on our next project. The new system consisted of 5, 4 foot long by 4 foot wide by 2 foot deep tanks. All were plumbed together and the last tank was used as a sump. From there the water was pumped through a manifold to 16 individual surge buckets. Each one fired at a random rate and created an incredibly turbulent and variable water flow pattern in each tank. The 4 foot drop from the surge to the tank allowed us to increase our flow dramatically using the free power of gravity. The whole system was run on a single sequence dart pump.
