Nu-Drain Underground Drainage System
Supreme under ground drainage and sewerage system have been designed with a view to modern man’s inclination towards health, hygiene and his aversion to filth and pollutants. Due to unpleasant nature of human waste, a drainage system should be “out of sight and out of mind”. Most of the drainage systems are actually hidden from sight. It is hence important that it should be of superior quality and should be able to function year after year without leakage or defects. It becomes unpleasant and expensive to address such problem that arise in conventional underground pipelines unexpectedly, and which may happen due to poor product quality or due to faulty construction and outdated technology.
This system is intended to carry soil and waste from S.W.R. drainage system to roadside sewers or drains and as sewerage system also. This system is highly recommended for buildings where hygiene is a prerequisite. The system can also be used for rainwater collection and disposal, including rainwater harvesting. In short the system provides complete solution for underground drainage and sewerage application. The system is completely watertight and hence it is free from ingress and seepage of water and hence considered to be most hygienic. Unlike conventional drainage products there is no fear of pollution of underground water, soil or ill effects on building foundations. In this fast age, this product is blessing to housing and construction industry as tremendous saving in time and labor is possible. This is because installation of this system is quite simple and fast. The choice of the raw material, the structural accuracy and the strict quality control imparts high degree of reliability.
System comprising solid wall uPVC Nu-drain pipes conforms to IS: 15328:2003 whereas structured wall hi-tech Eco-drain pipes are made as per EN-13476 and meet the requirements of IS: 15328 standard. Plastic moulded inspection chambers are made as per BS: 7158:2001.

4.Ultra 450 mm multiple inlet(s) with two 110 mm inlets at 45° and two 160 mm inlets at 90° with main inlet/outlet in 160 mm. Ultra 450mm chamber in different flow configurations with 200mm main inlet(s)/ outlet and 110, 160, and 200 mm branch inlet(s)
5.Ultra 1000 mm manhole with 160,200, 250, 315 inlet(s) / outlet in different configurations.
This unique inspection chamber of 250 x 110 mm in uPVC is featured with provision of 75 mm trap and hence one can directly combine soil and waste lines to reduce the cost. This is also available without trap and hence customer has choice to use this chamber as per site requirements. This small version of inspection chamber is recommended for small bungalows/ houses where maximum invert depth is up to 600 mm.
Ultra 315, Ultra 355 and Ultra 450
Ultra inspection chambers in different sizes comprise chamber base, riser(s) in specially designed polypropylene/PE grade whereas cover and frame is in uPVC. Entire assembly provides a completely sealed system up to ground level. It offers a wide variety of flow profiles, giving you an option for all 110-200 mm drainage applications.
A choice of different configurations provides a comprehensive, level invert system with excellent flow characteristics. The invert depth of Ultra Chambers with combination of different assemblies from top of cover to the channel inverts are given in the table. In case of 355 mm chamber 355 x 315 reducer is provided to adopt 315 mm riser and frame / cover.
Ultra 450 inspection chamber is designed to provide the method of collecting 110/160/200 mm drains at invert depth up to 1280 mm by the use of Ultra 450 risers. Maximum five risers are recommended. In addition to the risers, shaft pipe in different lengths are also made available which gives maximum invert depth 1330mm. Based on number of risers or shaft length used, invert depth obtained are given in table.
Concentric grooves are given on the exterior face of the riser which acts as cutting guides and shallower depths can be achieved by cutting the riser.
