Quick Answer
Choose cistern accessories based on your water storage needs, climate, and soil conditions. Consider factors such as cistern size, material, and shape, as well as accessories like lids, gauges, and overflow valves. Also, ensure the accessories are durable and can withstand extreme temperatures and weather conditions.
Selecting Cistern Accessories
When selecting cistern accessories, consider the size and shape of your buried concrete cistern. A standard cistern lid should be at least 6 inches larger than the cistern’s diameter to allow for easy opening and cleaning. For example, a 10-foot diameter cistern would require a 16-foot diameter lid.
Choosing the Right Material
Cistern accessories can be made from a variety of materials, including steel, aluminum, or PVC. When choosing materials, consider durability, corrosion resistance, and cost. For example, steel lids are durable and can withstand heavy loads, but they may corrode if not properly coated. Aluminum lids are lightweight and corrosion-resistant, but they may dent easily. PVC lids are inexpensive and easy to install, but they may not withstand heavy loads.
Installing Accessories
To install cistern accessories, follow these steps: 1) ensure the cistern is properly sized and aligned; 2) attach the lid to the cistern using secure fasteners; 3) install a gauge to monitor water levels; and 4) install an overflow valve to prevent water from spilling over the sides of the cistern. For example, a standard overflow valve should be installed 12 inches from the top of the cistern to prevent water from overflowing during heavy rain.
