Water Storage Solutions Every Homeowner in Ghana Should Consider

An Accra Street Journal Real Estate Intelligence Brief

For homeowners in Ghana, water storage is not a luxury—it is a necessity. Unreliable municipal supply, seasonal shortages, and the rising cost of water from tanker services make on-site storage a critical component of residential infrastructure. Academic research confirms that water storage containers are a key coping strategy for mitigating water insecurity, particularly the unreliability of water supplies . In the Krowor Municipality of the Greater Accra Region, for instance, studies show that in periods of water supply shortages, households turn to alternative systems, with the water tank (Poly tank) being the most preferred option .

This ASJ guide outlines the main water storage solutions available, their key features, and what every homeowner should consider before making an investment.

Part 1: Why You Need a Storage System

Water scarcity is not a hypothetical risk; it is a present reality driven by erratic rainfall, climate change, and a rapidly growing urban population. Experts note that the increasing water scarcity and the need for reliable supply infrastructure are primary drivers of the water storage systems market in Ghana .

Simply put, relying solely on the municipal grid leaves you vulnerable to supply interruptions. A well-chosen storage system offers several distinct advantages:

• Uninterrupted Supply: It provides a buffer during periods of rationing or pump failure.

• Cost Savings: You can store water when it is available and cheaper, reducing reliance on expensive tanker services.

• Emergency Preparedness: It ensures you have water for basic needs during a crisis.

• Property Value: A robust water storage setup can increase your home’s appeal to buyers or renters.

Part 2: The Main Solutions and What They Cost

Homeowners have several options, ranging from simple tanks to more complex systems like boreholes and rainwater harvesting. The choice depends on your budget, the space available, and the reliability of your local supply.

1. Polyethylene (Poly) Tanks

The most common and versatile solution for Ghanaian homes. These tanks are made from UV-stabilized, food-grade plastic, making them durable, lightweight, and rustproof . They are available in a wide range of sizes, from a few hundred to several thousand litres.

Key Features:

• Pros: Affordable, easy to install, portable, low maintenance, and available in various sizes.

• Cons: Can be susceptible to algae growth if not properly covered or cleaned.

• What to Look For: Ensure the tank is made from 100% UV-stabilised virgin plastic. Some premium brands, like Sintex, offer double-layer construction (black outer layer for structural support, white inner layer for hygiene) and provide a 7-year warranty .

2. Concrete Tanks

A permanent and highly durable solution, often constructed on-site. These are ideal for large-volume storage and are frequently used by developers for apartment buildings or large homes.

Key Features:

• Pros: Extremely durable, can be built to custom sizes, and are less susceptible to physical damage.

• Cons: High initial cost, permanent installation, and requires skilled labour to construct properly to prevent leakage.

• What to Look For: Ensure proper waterproofing and that the tank is designed to prevent contamination.

3. Underground Storage (Cisterns and Boreholes)

For homeowners who want to maximize space and integrate water systems seamlessly, underground options are worth exploring.

Borehole Systems: A borehole taps into groundwater. While the initial drilling and installation are expensive, it provides a near-unlimited, independent water supply. These systems often require a storage tank (poly or concrete) to hold the pumped water and a pressure tank to maintain water pressure in the home . A “mechanized borehole” system typically includes a borehole, pump, and an overhead storage tank .

Underground Cisterns: Rainwater harvesting can be directed into large underground reservoirs. A study in Kumasi found that managed aquifer recharge using rooftop rainwater harvesting with shallow wells significantly increased groundwater levels and recharged the aquifer .

Key Features:

• Pros: Boreholes provide independence from the municipal grid. Rainwater harvesting can be used for landscaping and non-potable uses to reduce strain on your main supply.

• Cons: High upfront cost for boreholes; underground cisterns require significant excavation and construction.

• What to Look For: Borehole drilling should only be done by licensed professionals with a proven track record.

Part 3: The Cost of Water Storage in Ghana (2026)

Costs vary significantly based on size and material. The market includes a range of suppliers and sizes, from smaller plastic tanks to large industrial vessels .

A significant community-level example is the Public Utilities Regulatory Commission’s (PURC) pro-poor water projects, which install mechanised boreholes with a 10,000-litre storage tank to serve entire communities .

Part 4: Key Considerations Before You Buy

1. Sizing Your Storage

Do not just buy the biggest tank you can afford. You need to calculate your daily water consumption and the frequency of shortages. A household of four with frequent supply interruptions will need a larger buffer (e.g., a 10,000-litre tank) than a single professional with a reliable supply (who may only need a 1,000-litre tank).

2. Quality and Material

Invest in quality. Poly tanks should be UV-stabilised to prevent degradation from Ghana’s harsh sun. Look for FDA-approved food-grade materials to ensure hygienic water storage. Lower-quality plastics may leach harmful substances over time .

3. Installation and Maintenance

Proper installation is crucial, especially for boreholes and concrete tanks. Ensure that systems are installed by qualified professionals. Regular cleaning and inspection of tanks, gutters (if harvesting rainwater), and pumps will prolong the system’s life and ensure water quality.

4. The Government and Regulatory Framework

The government recognizes the importance of water storage infrastructure and is formulating policies to promote investment in it . The PURC has been active in providing water systems to underserved communities, often installing a 10,000-litre storage tank with the borehole . This signals a growing policy focus on decentralized water solutions, which could lead to more support and standards for homeowners.
