Pipa delivery planner

Use your cistern readings to plan the next delivery. First, estimate daily use: add the starting volume and all incoming water, subtract the ending volume, then divide by elapsed days.

Usable cistern capacity (L)Water available now (L)Measured daily use (L/day)Reserve you want to keep (days)Confirmed delivery lead time (days)Quoted delivery volume (L, optional)Total quoted price (MXN, optional)

Adjust the example values of 2 reserve days and 1 delivery day to suit your plan. Use the lead time your supplier confirms.

Your estimate

Enter valid capacity, current volume and daily use. Current volume cannot exceed capacity.

How the estimate works

Order threshold = daily use × (reserve days + delivery lead time). Time until ordering = (current water − order threshold) ÷ daily use, with a minimum of zero days.

The calculation assumes constant use and no other incoming water. Irrigation, guests, leaks or municipal supply can change the result. Confirm price and availability with your supplier to book a delivery, and check the water level again before unloading.
