How to choose, manage plastic water tanks

With changing weather patterns and unpredictable rainfall, Joyce Nalweyiso worries about her poultry project.

She does not want to rely on purchasing water to sustain her business, so she has decided to install a plastic water tank at her home to ensure a continuous water supply.

However, she is unsure of the type, size, and price of the tank she needs. She is not alone in this dilemma.

Choosing a high-quality plastic tank

Wilberforce Mukasa, the president of the Uganda National Plumbers Association, notes that the growing demand for plastic tanks has led to an influx of different brands and designs in the market.

However, not all tanks meet the same standards. Homeowners should invest in high-quality tanks that offer durability, efficiency, and added value.

UV protection and durability

A high-quality tank should be made from UV-resistant material to prevent degradation from prolonged sun exposure. This ensures a longer lifespan and maintains the quality of stored water.

Mukasa says some modern plastic tanks incorporate anti-microbial technology to prevent algae and bacterial buildup. This feature is particularly important for households using stored water for drinking and cooking.

Space-saving and customisable designs

Ajay Jain, a dealer in water tanks says a unique design allows homeowners to maximise their available space.

Vertical tanks are ideal for small compounds, while horizontal tanks fit under verandas or in compact spaces. Some models come with compartments for multiple uses, such as separate sections for drinking water and irrigation water.

Proper tank installation and maintenance

Mukasa stresses the importance of proper installation and regular maintenance. The tank should be placed on a strong, level surface to prevent tipping or structural damage.

A secure connection to gutters ensures effective rainwater collection. If used for drinking water, proper filtration and treatment methods should be applied.

Cleaning and maintenance

For easy maintenance, plumbers should install a bottom valve on plastic tanks to facilitate periodic cleaning.

“The valve allows users to open and close the tank for cleaning purposes,” Mukasa explains.

When cleaning the tank, one should close the valve, climb the stand, scrub the interior with detergent, and then open the valve to let the dirty water out.

Mukasa also emphasises the importance of covering overflow outlets to prevent mosquito breeding.

“Some homeowners do not cover the overflow, allowing mosquitoes to lay eggs in the tank. These eggs develop into larvae, which can be found in many neglected tanks,” he says.

Plastic tanks should be cleaned at least every six months with detergent and thoroughly rinsed.
