The Ultimate Guide to Blue Cistern Liners: Types, Applications, and Benefits
Cisterns are essential for water storage, especially in areas where water supply is limited or unreliable. To maintain their integrity and functionality, many owners choose to install cistern liners. This guide will explore the various types of blue cistern liners available in the market, their applications, and how they can extend the life of your cistern. We will also provide comparative tables highlighting the differences between various types of liners and their technical features.
Types and Applications of Blue Cistern Liners
| Type of Liner | Material | Potable Water Safe | Durability | Application |
|---|---|---|---|---|
| Reinforced Polyethylene (RPE) | Reinforced Polyethylene | Yes | High | Large cisterns, both potable and non-potable |
| Polyvinyl Chloride (PVC) | PVC | Limited | Moderate | Residential, non-potable applications |
| Chlorosulfonated Polyethylene (CSPE) | Synthetic Rubber | Yes | High | Chemical exposure, high-temperature storage |
| Flexible Polypropylene (fPP) | Polypropylene | Limited | Moderate | Chemical holding, not ideal for drinking water |
| Hydraulic Cement Coatings | Hydraulic Cement | No | Low | Stabilization, requires additional lining |
| Epoxy Tank Coatings | Epoxy Resin | Limited | Moderate | Small cisterns, sealing cracks |
| Custom Fabric Liners | Various fabrics | Yes/No | Varies | Tailored to specific cistern dimensions |
Understanding Cistern Liners
What is a Cistern Liner?
A cistern liner is a waterproof barrier that is installed inside a cistern to prevent leaks, protect the stored water, and extend the life of the tank. Liners can be custom-fitted to meet the specific dimensions of the cistern, ensuring a watertight seal.
Importance of Cistern Liners
Installing a cistern liner has numerous benefits, including:
- Leak Prevention: Liners act as a barrier against leaks caused by cracks and porous surfaces.
- Water Quality Preservation: High-quality liners can prevent contaminants from entering the water supply.
- Cost Savings: Rather than replacing an entire cistern, a liner provides a cost-effective solution for extending its life.
- Ease of Installation: Many liners can be installed quickly, minimizing downtime.
Types of Blue Cistern Liners
Reinforced Polyethylene (RPE)
Reinforced polyethylene liners are highly recommended for both potable and non-potable water cisterns. They are durable, flexible, and resistant to tears and punctures. RPE liners can easily conform to the shape of the cistern, making them ideal for complex configurations.
Polyvinyl Chloride (PVC)
PVC liners are flexible and relatively inexpensive. However, they may leach chemicals into drinking water, making them less suitable for potable applications. PVC is often used in residential settings for non-potable water storage due to its affordability.
Chlorosulfonated Polyethylene (CSPE)
CSPE is a synthetic rubber liner that can withstand extreme conditions, including chemical exposure and high temperatures. While more expensive, it provides superior durability and is suitable for specialized applications.
Flexible Polypropylene (fPP)
fPP liners are often used for chemical holding due to their corrosion resistance. However, they are not recommended for potable water use as they may not provide the necessary durability.
Hydraulic Cement Coatings
Hydraulic cement coatings are often used as a primary liner for older concrete cisterns. While they can stabilize the structure, they require an additional impermeable layer to contain water effectively.
Epoxy Tank Coatings
Epoxy coatings provide a liquid solution for sealing small cracks but may not be suitable for larger cisterns. Their application is straightforward, but they may not be safe for potable water.
Custom Fabric Liners
Many manufacturers, including DLM Plastics and Clarion Municipal, offer custom fabric liners tailored to specific cistern dimensions and requirements. These liners can be made from various materials, ensuring the right choice for each application.
Cistern Liner Applications
Cistern liners have a wide range of applications, including:
- Agricultural Use: Protecting water supplies used for irrigation and livestock.
- Residential Settings: Ideal for homeowners looking to maintain a clean water supply.
- Emergency Water Storage: Providing reliable water sources during emergencies or natural disasters.
- Commercial Applications: Supporting businesses that require large water storage solutions.
