Check the pressure ratings of your pipe as well. 6.5-8 bars (minus pipe-friction losses especially if using small diameter pipes) are not too bad for good quality HDPE pipe (PN10 or PN16) at typical temperatures. See also: https://www.engineeringtoolbox.com/docs/documents/327/pe_pipe_temperature_operating_pressure.png (includes a safety margin of course)
That way you preserve pressure in the pipes for further extensions of peak demand periods.
Here in the mountains of Nepal often a combination of small BPT and small flow reducers directly at the taps is used. Normally the BPT are only found in the (often very steep) delivery pipe to the main RVT. After that the flow reducers at the tapstands are sufficient and allow a very fine-grained demand management at each tapstand.

Here in the mountains of Nepal often a combination of small BPT and small flow reducers directly at the taps is used. Normally the BPT are only found in the (often very steep) delivery pipe from the spring source to the main RVT. After that the flow reducers at the tapstands are sufficient and allow a very fine-grained demand management at each tapstand.
