Equivalent Capacities for Multiple Barrel Culverts - Guidelines
In some cases a large single culvert may not be the most practical option.
See Table 2.1 on Culverts Guidelines for suggested construction sizes and options, this gives equivalent multiple barrel culvert installations, which will provide the required culvert capacity.

Application
Maxiculvert incorporates the strength of a corrugated outer wall and a smooth inner wall to provide optimal flow, high stiffness-to-weight ratio and unsurpassed resistance to abrasion and corrosion. Maxiculvert is designed for (but not limited to) agricultural and forestry applications. Maxiculvert can also be perforated for water management applications and groundwater infiltration.
Optimum Hydraulics
Using modern co-extrusion techniques, the pipes are manufactured with a smooth bore for optimum flow capacity. Longer lengths and fittings help reduce hydraulic losses.
Fittings
Maxiculvert comes with a complete range of plastic-welded fittings, including 11-90° Bends, 45 & 90° Junctions, Couplers, Ends Caps, Reducing Couplers and Reducing Junctions. Custom-made fittings are also available.
