Western Water Products provides both Hopper Bottom Pits and Flat Bottom Pits and other sumps to meet individual requirements for wash pad drain requirements and water collection.

Hopper Bottom Pit

The HOPPER BOTTOM PIT is manufactured of heavy-duty, non corrosive poly material.  It can be utilized as:

  • Primary sump on located on a wash pad
  • A downstream collection pit fed by a smaller sump or trench drain
  • An intermediate pit located prior to a multi-compartment clarifier

The Hopper Bottom Pit is usually used as the primary or secondary pit in the wash pad drainage system and acts as  solids settling pit.  It is typically used when the end user desires to have the ability to remove unwanted sludge build-up from the pit.  In this case A Model SRS Sludge Removal System with a Heavy-Duty Sludge Pump is located at the bottom of the pit and controlled by Timing Panel which energizes the pump frequently to evacuate solids which settle to the bottom of the pit.  The sludge is then deposited into an Above Ground Sludge Collection or Mud Hopper for easy disposal.

An installation guide for the Hopper Bottom Pit is provided with the pit.  A Galvanized Steel Support Ring, Lip Cover and 2-piece Traffic Rated Steel Grate is provided as part of a complete Pit Kit.  Reference Model #HBP-KIT when ordering in this manner.  

If the Pit is used as a drainage pit through which water will enter, an Under-the-Grate Strainer Basket is required to prevent pump damage.  Trench Strainer baskets are available as well.  (See above Photos) Reference #FBS-002 when ordering. 

Bulkhead fittings are sold separately.  Up to 5 Bulkheads may be required depending on the number of connections going to and from the pit.
