Series 435 Tnemec Perma-Glaze is an epoxy coating that is factory applied after sandblasting and priming with Series 218 Tnemec Mortarclad. It serves as a deterrent to abrasion and Hydrogen Sulfide (H2S) off gassing. This allows the concrete and steel components of the wet well to last longer.
What is a drop bowl and what is it used for?
A drop bowl is an assembly made of PVC and mounting hardware. It appears similar to a funnel or bowl mounted on top of a vertical pipe. The device is mounted to the inside wall of the sump slightly below the inlet pipe. The bowl collects the inflows of water or sewage and diverts the flow to the bottom of the sump. This function helps protect the pumps and other in-well components that could be …
What is a deflector panel and what is it used for?
A deflector panel is made of HDPE panels, stainless steel brackets, and mounting hardware. This panel is attached to the inside of the wet well in front of the inlet pipe. As water flows in, the panel diverts the incoming flow to the bottom of the wet well. High or moderate flows of cascading water can damage the pumps and other in-well system components, but a deflector panel protects these elements by redirecting the inflow. …
What is a barrel gasket?
A barrel gasket is typically an isoprene tube (synthetic rubber) with its own lubrication that is placed between two precast concrete barrels. The gasket helps seal the manhole from water intrusion or leakage at the joints. Barrel gaskets are also made from other materials so that they can be used with different water types and water chemistry. Barrel gaskets are used in conjunction with tape coating and a concrete sealant to seal the joints in …
What components make up a standard wet well configuration?
A typical sump or wet well will include the concrete or fiberglass barrels; an access hatch; an inlet line (piping) with a deflector panel or drop bowl; the pumps, guide rails, elbows, and discharge piping; and the level sensing devices.
