Quick Answer
To fill a newly installed cistern, use a combination of water sources, starting with a slow fill rate to prevent sedimentation and overflow, and finishing with a clean water rinse to ensure purity. Fill the cistern from the bottom up, using a hose with a filter to prevent debris entry. Test the water quality at the end of the fill process.
Filling the Cistern
When filling a newly installed cistern, it’s essential to do so in a controlled manner. Start by filling the cistern from the bottom up, using a hose with a 50-micron filter or smaller to prevent debris and sediment from entering the tank. The fill rate should be slow, around 1-2 gallons per minute (GPM), to prevent sedimentation and overflow. This may take several hours, depending on the cistern’s size and the water source’s flow rate.
Water Quality Considerations
As the cistern fills, it’s crucial to prioritize water quality. Use a water source that is free from contaminants, such as a municipal water supply or a well with a high quality water test. If using a surface water source, such as a rainwater collection system, ensure that the water is treated and filtered before filling the cistern. Test the water quality regularly during the fill process to ensure it meets or exceeds local health standards.
Finishing Touches
Once the cistern is filled, it’s essential to perform a final rinse with clean water to ensure purity. Use a hose with a 10-micron filter or smaller to flush out any remaining debris or sediment. Test the water quality again after the rinse to confirm it meets local health standards. This final rinse will help maintain the cistern’s water quality and extend its lifespan.
