Water & Sewer Network Calculations
Budget: $750 – $1,500 USD
I need complete design-stage calculations for a proposed water-supply and sewerage/drainage network and would like them compiled into a clean, review-ready package that aligns with international standards such as ISO and ANSI.
For the potable water system, focus only on accurate demand estimation for the served population and the resulting pump selection that meets those peak and average flow scenarios. No pipe sizing is required at this stage, but the pump curves must be matched to the calculated duty points and clearly documented.
For the foul/combined water network, please develop:
• Flow-rate estimation for peak, average and minimum conditions
• Pipe sizing that satisfies hydraulic grade line requirements and self-cleansing velocity checks
• Pump selection with full operating envelopes and NPSH verification
The final submission should include calculation spreadsheets (Excel or recognised hydraulic software output), a concise design brief explaining assumptions, and any supporting graphs or pump data sheets—everything formatted so it can slot straight into our master report.
