Manhole extensions are installed on top of the tank to bring it up to ground level and allow access to the tank when needed. They come in heights of 6 inch, 1 foot, 2 foot and 3 foot. They are 30" inside diameter and 36" outside diameter, allowing enough room for a ladder and man to enter the tank. The delivery driver has a selection of all sizes with him. Each joint of an extension must be sealed with Butyl tape.
Butyl tape is an extruded flow-resistant tape that provides an exceptional seal between concrete locking out ground water and moisture. This is essential for septic tanks to reduce run time of your effluent pump and not saturating your septic field.
Manhole cover lids are a 36" outside diameter. Lids are designed to fit Bashaw Concrete manufactured manholes which are 36” outside diameter and 30” inside diameter. The bottom on the lid is not flat. The center area of the lid is slightly lower than the edges, allowing the lid to recess inside the ring of the manhole. This design allows for a more secure fit on the manhole, also helping to prevent slight bumps from dislodging the lid.
Replacement Manholes & Lids
We have replacement pieces for your septic tank should you ever have a problem where something has been damaged. Have a really old tank with a two foot square lid? We still make the extensions and cover lids for them as well.
Effluent Filters & Handle
Insulated Cover Lids
Another requirement of the Private Sewage Regulation (Alberta) is an insulated cover lid. The insulated cover is held by gravity inside the manhole just under the concrete cover lid and can easily be removed when needing access to the tank.
