„ELPLAST+” Sp. z o. o. manufactures, using rotational moulding, polyethylene manholes 1000 mm in diameter designed for external gravity pipeline systems (sewage piping and stormwater drainage), pressure drainage systems, stormwater pipelines and water supply systems – as inspection chambers, catch pits, decompression manholes, desilting manholes and for sewage pumping stations. Elplast+ manholes can be used both in the areas protected from heavy loads and these exposed to such heavy loads like roadways.
The manholes are manufactured in three versions: reinforced version (consisting of reinforced ‘WZ’ components), standard version (consisting of standard ‘ST’ components) and optimum version (consisting of both standard and reinforced components combined). Your choice of a manhole version should depend on the design requirements.
Standard: AT /2007-02-2237/2; PN-EN 13598-2
Light weight of the components
Resistance to chemical corrosion
High resistance to aggressive waste water, aggressive groundwater and contaminated polluted soil
Non-toxicity for the environment – no emission of any substances during operation
Excellent abrasion resistance (several Times higher than for concrete, GRP, PVC)
Low investment cost
Easy and quick assembly, even in harsh local conditions
Excavation can be really narrow, with dimensions close to the manhole dimensions
No heavy equipment is necessary to install the manhole – lower investment costs
