With climate change bringing more extreme weather, planning for adequate clean water is more important than ever. SimTanka helps you estimate, collect, store, and monitor rainwater for household use. SimTanka downloads past daily rainfall records for your location so you can see seasonal variations and drought cycles. Use this data to set a realistic daily household water budget tailored to your needs. SimTank then suggests optimal rainwater tank sizes to meet your budget based on the historical rainfall. Large tanks can be expensive, but undersized tanks won't provide enough water. This feature takes the guesswork out of planning tank capacity. Worried about droughts and shortages? SimTanka looks ahead 30 days using forecast data to estimate your available rainwater. You’ll know in advance if rationing may be required. After installing your system, the app becomes your water diary. Log each rainfall event and the amount collected in your tank. Note any water quality issues like odor or debris that require treatment. Record maintenance like filter changes and roof washing. Knowing your water supply and demand helps preparation. Store extra in times of plenty, and conserve when lean times arrive. With climate uncertainty, a good rainwater harvesting plan brings resilience and peace of mind. This app provides the information you need to create a reliable, safe home rainwater system.
