What is DECILO Low Noise PP Drainage? Durable & Efficient Drainage Solution

Modern high-rise buildings require drainage systems that are not only durable but also quiet and efficient. Traditional drainage pipes produce noticeable sounds when water flows through them, especially in multi-storey buildings. This is where the DECILO Low Noise PP Drainage System stands out. Designed using advanced mineral filled Polypropylene polymer, it helps reduce unwanted plumbing noise while delivering reliable drainage performance.

The DECILO Low Noise PP drainage system is a specially engineered polypropylene drainage system designed to minimise noise generated during wastewater discharge and is Fraunhofer certified with a sound level of 13 dB(A) at a flow rate of 2.0 L/s. These low noise drainage pipes are built with advanced material composition and acoustic design that significantly reduces vibrations and sound transmission.

Manufactured using mineral-filled polypropylene, the system offers excellent strength, durability and chemical resistance, making it suitable for modern high-rise building plumbing requirements. It also supports high-temperature operations up to 90°C for continuous operation and 95°C for intermittent exposure.

With a triple-layer pipe structure and precision fittings, DECILO delivers an efficient low noise drainage system ideal for residential, commercial and institutional buildings.

The DECILO Low Noise Drainage System combines innovative design with advanced material technology to create a durable and efficient drainage solution. One of its standout features is the triple-layer pipe structure that helps absorb vibrations and limit sound transmission through the building structure.

The outermost layer of the pipe is made from flame-retardant polypropylene that protects the pipe from external stress and environmental impact. The middle layer is mineral-filled and reduces stiffness while improving acoustic insulation, whereas the innermost layer provides a smooth surface to ensure uninterrupted wastewater flow.

Additionally, these silent drainage pipes are resistant to chemicals across a pH range of 2–12 and can handle high-temperature wastewater without losing performance. The ring-fit rubber ring joint system enables leak-proof installation while also simplifying the assembly process.

Choosing a low noise drainage system like DECILO offers multiple practical benefits, the key benefits are:

Acoustic Comfort

In traditional drainage systems, the sound of water rushing through pipes travels through walls and floors, disturbing occupants. DECILO’s advanced Low Noise Drainage System reduces both airborne and structure-borne noise. This helps in maintaining a quieter indoor environment.

Durability

The polypropylene drainage system has strong impact resistance and provides long-term performance. This ensures the pipes remain reliable even in demanding environments. The ultra-smooth inner surface of the pipe helps prevent deposits and clogging. This helps in maintaining consistent flow efficiency over time.

Other notable features

The system’s ring-fit design reduces installation time and labour costs, making it an efficient choice for large projects. In addition, the materials used are recyclable, making DECILO a more sustainable alternative for modern drainage solutions.

Applications of DECILO Low Noise PP Drainage Pipes

The DECILO Low Noise PP Drainage System is designed for a wide range of building applications where efficient and quiet drainage is essential.

Residential apartments and villas are among the most common applications. In multi-storey housing, vertical drainage pipes often generate significant noise when toilets, sinks or showers are used. Installing silent drainage pipes helps maintain a peaceful living environment for occupants.

Hotels and hospitality establishments also benefit greatly from low noise PP drainage pipes, as guest comfort is a priority. Hospitals and healthcare buildings require hygienic and reliable drainage systems, and the chemical resistance of PP drainage pipes makes them well-suited for these environments.

Educational institutions, commercial buildings and laboratories also use this high-rise drainage pipe system to ensure reliable wastewater management.

Noise in drainage systems is generated when water, air and solid particles flow through pipes at high speeds. As these elements hit the pipe walls and fittings, they create vibrations. These vibrations then travel as sound through the building structure and become audible inside rooms.

The DECILO Low Noise PP Drainage System resolves this issue through material engineering and structural design. The mineral-filled intermediate layer in the pipe absorbs vibrations and reduces sound transmission, while the smooth inner surface ensures steady flow with minimal turbulence.

Additionally, the ring-fit rubber ring joints work to isolate the vibrations, preventing them from spreading through the structure. When combined with acoustic pipe clamps, the system further reduces structure-borne noise.

This integrated approach allows DECILO to function as a high-performance low noise drainage system.

The DECILO Low Noise PP Drainage System introduces a modern approach to wastewater management. With its advanced material composition, triple-layer design and reliable ring-fit connections, it provides a durable and efficient polypropylene drainage system that ensures quieter, long-lasting drainage performance.
