Quick Answer
Regularly inspect cisterns for signs of water seepage or structural damage during harsh winter conditions, and apply a waterproof coating to the cistern's interior and exterior surfaces to prevent water infiltration. Remove any debris or sediment that may have accumulated at the bottom of the cistern. Consider installing a freeze-proof cistern lid or adding insulation to the lid to prevent ice formation.
Inspecting Cisterns for Winter Damage
Inspect cisterns at least twice a year, once before winter and once after, for signs of water seepage, structural damage, or sediment buildup. Check the cistern’s walls, floor, and lid for cracks or holes that may allow water to enter. Use a waterproofing spray or sealant to address any detected issues. Remove any debris or sediment that may have accumulated at the bottom of the cistern, as this can attract pests and create an environment for bacterial growth.
Preparing Cisterns for Winter Conditions
To protect cisterns from freezing temperatures, apply a waterproof coating to the interior and exterior surfaces of the cistern. This can be done using a mixture of water and liquid latex paint or by applying a commercial waterproof coating. Consider installing a freeze-proof cistern lid or adding insulation to the lid to prevent ice formation. This can be achieved by wrapping the lid with insulation materials like foam board or fiberglass.
Additional Precautions for Buried Concrete Cisterns
For buried concrete cisterns, it’s essential to ensure the surrounding soil is properly compacted and graded to prevent water accumulation. Check the cistern’s drainage system to ensure it’s functioning correctly and direct water away from the cistern. Consider installing a French drain or a sump pump to further protect the cistern from water infiltration. Regularly inspect the cistern’s buried sections for signs of damage or wear and address any issues promptly.
