Flush seawall bilge-pump discharge splash collars

A bilge pump that dumps onto a seawall cap or a paver dock landing leaves a dark fan of stains, washes polymeric sand out of the joints, and undermines the edge restraint. On Pinellas canals that discharge runs every time a boat takes on rain. A flush splash collar gives the water a defined exit instead of a sheet across the pavers.

What the collar does

We set a small recessed concrete or paver collar at the discharge point, pitched to the water side of the cap or to a drain that does not cross the walking surface. The collar sits flush so a dock cart and a bare foot do not catch an edge. The bilge hose terminates inside the collar, not on top of the field pavers.

Where we use them

• Seawall caps where a boat-lift bilge currently stains the concrete.

• Paver landings at finger piers and seawall stairs.

• Side-yard paths that carry a rinse line from a jet-ski dock.

• Retrofits when the cap is sound but the discharge is eating the joint sand.

This is a hardscape detail, not a marine electrical job. We coordinate the hose location with the dock contractor and build the collar into the paver or cap work. PaverForge Hardscapes serves St. Pete Beach, St. Petersburg, and the Pinellas barrier islands. Call (727) 490-9798.
