Siphon pit Ø315

The RASAN brand drainage manholes are made up of several elements manufactured in PE using the rotational moulding technique.

The pits are supplied with the desired height and for this purpose these elements are joined together until they reach the required height.

As a final result we obtain a perfectly watertight polyethylene pit, which prevents any infiltration of water into the ground or vice versa, making these pits ideal for ground with water tables and preventing the contamination of aquifers.
