Inspection Chamber at every Joint

[Crusader36]

Dear techies, I have attached a pic of commercial sewer drainage line. Here the designer put Inspection chambers at every joint or junction. He put chambers at even 1.5mts distance which is just weird.

I don't think this as proper way. If we keep adding IC at every joint and junction the whole lane will be filled with ICs. Isn't there other option to this. Like I think we can omit the ICs by joining the incoming pipes with two 45 degree elbos. ICs should be added every 20mts.

It depends what the code says. In the UK, in residential developments, if a foul pipe contains solids it must go to an inspection chamber. This is to allow access for maintenance. If the line is only taking foul water with no solids i.e. hand basin or a urinal it can just saddle on or connect via a 45 angle. RWPs should be able to connect directly to the main line with no ICs required. That doesnt help you here since its a combined system.

Just raise the question with the designer. Or if you know someone in the local council/authority, ask them if it is permitted to connect directly to the line without an IC. Note : that it would be advisable to include a vertical rodding eye detail on the line (if not going to an IC) before it connects to the main line.
