I am new to rising main design and any expert would help with my question, really appreciate here
1. is there a requirement for putting inspection chamber at certain distances for maintenance like say every 100m?
2. is air valve at every high point and scour valve at every low point a must? both for water supply rising main and wastewater rising main, maybe the watersupply rising main doesn't need the scour valve at low point?
3. is there a maximum pipe deflection? less than 45 degree is acceptable? Need concrete thrust block at each turning point?
4. Anything major to look out during the design?
My working experience is all gravity sw/ss pipes and not too sure about the rising main so i think it's the best place to ask here
