Eliminates Manhole I/I problems
The Lifespan System is the only watertight, corrosion proof,and highly durable manhole frame and cover system on the market specifically designed to eliminate unwanted inflows at the cover and chimney area of a manhole. The frame and adjustable risers are made of the same ultra high-performance rubber that has been used in transportation for more than 50 years.
The Lifespan System saves money because it outlasts anything presently available. With Lifespan, existing sewers are more efficient, so the cost of increasing capacity is delayed. The system is watertight at all critical points, eliminating inflow and infiltration. The locking cover, available in cast iron and a lighter weight composite material, provides a positive seal between the cover and the frame. Lifespan absorbs vehicular impact so the system, manhole structure and surrounding pavement remain intact, saving on costly repairs. The system is also installation-friendly, as the 24- inch frame weighs only 55 pounds. This makes the system advantageous for installations or rehabilitation projects lying in easements or environmentally sensitive areas, where it would be challenging to get heavy equipment.
