Reducing septicity in rising mains
If you have any simple rising mains, rather than ones with more complex vertical profiles, you might try using a compressor to add air to the main. It also keeps the main clean but there can be a problem at the receiving end as the unused nitrogen has to escape to atmosphere.

Good idea, but there are concerns with air retention in mains causing surge conditions. Bubble size is the key.
Thank you for your contribution
