Ovoid Pipes

With higher velocity at low flows, reducing the risk of siltation and sewer blockages, Ovoid pipes are ‘egg-shaped’ and can offer lower operating costs, as sewers may be laid without the need for pumping.

Ovoid pipe solutions can be commonly found in Victoria brick-built sewer systems and in some circumstances, concrete ovoid drainage pipes are used to replace parts of an existing sewer network.

Marshalls Civils & Drainage Ovoid concrete pipes are produced and tested in accordance with the relevant provisions of BS EN1916:2002/BS5911-1:2002 Class 150 including dimensional tolerances, crushing, hydrostatic, water absorption and joint tests.

Avaliable are various lifting options depending on size. The 600mm × 900mm and 800mm × 1200mm pipes are supplied with two lift anchors cast in the top for use with ‘Flexilift’ lifting/jointing system, whereas the ‘C’ hook is available for lifting/jointing 400mm × 600mm ovoid’s. All Ovoid pipes have lifting jointing equipment available on request.

Benefits of Ovoid Pipes:

• Lower operating costs, where some sewers may be laid without the need for pumping.
• Better self cleansing and therefore less risk of siltation and blockage.
• Sustainable, strong and durable sewerage solution with a 120-year design life.
• Reduced costs of trench excavation resulting from shallower gradients.
