British water flows and loads 4 document states that:
4 bedrooms = 6 people
5 bedroom + 6 bedroom property = 7 people + 8 people = 15 people.
Then multiply by 0.9 & round up: 15 x 0.9 = 13.5 (14 rounded up)
All UK treatment plants for domestic use are rated in their maximum population equivalent (PE), there are many different makes and models all using various styles of treatment and made from different materials. Some are noisy, some are silent. Most cheap sewage treatment plants will use budget air blowers which won’t last as long and will be noisier than more expensive alternatives. A more expensive model will normally contain a higher quality of components and be engineered to a better degree.
In the long term this normally results in less failures, call outs and a cheaper lifecycle cost.
