MANHOLES

Standard Precast Concrete Manholes:

Description: ASTM C 478, precast, reinforced concrete, of depth indicated, with provision for sealant joints.

Diameter: 48 inches minimum unless otherwise indicated.

Ballast: Increase thickness of precast concrete sections or add concrete to base section as required to prevent flotation.

Base Section: 6-inch minimum thickness for floor slab and 4-inch minimum thickness for walls and base riser section, and separate base slab or base section with integral floor.

Riser Sections: 4-inch minimum thickness, and lengths to provide depth indicated.

Cast or anchor steps into sidewalls at 12- to 16-inch intervals. Omit steps if total depth from floor of manhole to finished grade is less than 60 inches.

Retain one of two subparagraphs below if required to raise top of manhole to grade.

Adjusting Rings: Interlocking HDPE rings with level or sloped edge in thickness and diameter matching manhole frame and cover, and of height required to adjust manhole frame and cover to indicated elevation and slope. Include sealant recommended by ring manufacturer.

Grade Rings: Reinforced-concrete rings, 6- to 9-inch total thickness, to match diameter of manhole frame and cover, and height as required to adjust manhole frame and cover to indicated elevation and slope.

EXECUTION

TANK INSTALLATION

A. Information to be provide later

TANK ACCESS RISER INSTALLATION

Excavate and expose sufficient width and length of concrete tank top to provide a clean area for riser installation.

Select riser section heights so that the top of the lid will be slightly above surrounding grade, 1” to 2”.

Clean concrete tank top to allow a permanent waterproof connection. Connect riser adapter ring to concrete tank top using butyl sealant tape and corrosion resistant fasteners. Connect riser sections to adapter and to each other with stainless steel screws, per manufacturer’s instructions.

Backfill with excavated soil, sloping surrounding soil so water drains away from lid. Grade surrounding soil to allowing for ease of mowing without damaging lid.

EFFLUENT FILTER INSTALLATION

Completely pump all contents from the septic tank before installing the effluent filter.

Thoroughly clean and prime the existing outlet pipe before gluing in new filter. Test the fit and add any needed extensions to the filter so the filter is centered and easily accessible under the access riser.

Attach filter lifting rod extension so that handle is easily reachable within the riser.

Refill septic tank with water.
