A 1000-litre capacity cold water storage cistern (CWSC) should be equipped with a suitable inlet control valve to regulate the inflow of water, a ballcock or float valve to maintain water levels, and an overflow outlet to prevent spillage. Additionally, it should have adequate insulation to prevent freezing and contamination, along with a means to access for maintenance, such as a manhole. Finally, it should be constructed from materials that comply with water quality regulations to ensure the water remains safe for use.
