The Installers View on… Septic Tank Pump & Compressor Sound Enclosures.
We were called to see if we could help with a loud high Frequency noise in Kineton in Warwickshire, a small town between Warwick & Banbury.
Some residences were suffering from noise pollution caused by an electric motor installed on their septic tank sewage system.
Septic tanks, are very common in the country side or rural areas where there is no connection to the main sewage pipe. Approximately 25% of the population relies on septic tanks for their sewage. It is quite common that these communal septic tanks, which are installed for more than one household, include a pump or compressor of some kind of electric motor. It is the pumps that produces a high pitched sound.
This high frequency sound was very annoying for the residence, so much that it was almost unbearable and therefore difficult to relax in their gardens without hearing this noise. The residence could not open their windows at night because the noise became so irritating.
TP Soundproofing were tasked with reducing this noise.
The noise was high-pitched (so more waves per second than say a bass drum for example), so the design of the soundproof pump enclosure had to be airtight, and both reflect and absorb sound on the inside. It had to have the appropriate ventilation, easy access for maintenance, and look aesthetically pleasing against the residential barn conversion around it. It also needed to be removable out the way when the septic tank lorry arrived to empty the tanks.
The Pump enclosure was constructed using all the latest soundproofing products on the market today. We used the new rubber roof system from a Coventry based business and basic builder merchant ship-lap treated timber effect for the sides. We produced an athletically pleasing airtight soundproofed pump enclosure, with easily removable lid, adequate ventilation direct to the pump. The whole pump enclose can be transported. And most importantly you can no longer hear the high-pitched noise. So what did the residence think of the result?…“99% sound reduction. Could be 100% but a with a slight risk of overheating”… “I would have no hesitation in recommending TP Soundproofing and would be happy to discuss any enquiries”
