Domestic Water Supply - Lime Deposits

Lime deposited vs. temperature and water consumption. Calculate lime deposits in water supply systems based on dissolved calcium and magnesium (hard water) at various temperatures and consumption rates.

Temperature (°C)	Water Hardness (mg/L)	Annual Consumption (m³/year)	Estimated Lime Deposits (kg/year)

50	170	1500	4.2
60	170	2000	5
70	170	2000	6.2
80	170	2500	8.5
90	170	3000	11
