Yes, we do. Xmun Projects Ltd. offers a comprehensive well repair and restoration service, and it is one of the areas of our work that reflects a deep connection to the traditional building culture of Malta and Gozo. Wells — or cisterns, as they are more accurately described in many cases — have been an essential feature of Maltese properties for centuries. In a country where natural freshwater sources are scarce and rainfall is concentrated into a few months of the year, the ability to capture, store, and use rainwater has always been a matter of practical necessity. Nearly every traditional farmhouse, townhouse, and even many modern properties in Gozo and Malta have a well or cistern beneath them, and keeping these structures in good working order remains just as important today as it ever was.
Malta is one of the most water-scarce countries in Europe. The islands receive an average of around 550 millimetres of rainfall per year, almost all of it falling between October and March. There are no rivers or permanent lakes. Historically, the Maltese people relied on a combination of natural springs, hand-dug wells tapping the perched aquifer, and rainwater cisterns to meet their water needs. The tradition of collecting rainwater from rooftops, courtyards, and paved surfaces and channelling it into underground stone-lined cisterns became a fundamental part of Maltese domestic architecture. In Gozo, where the rural landscape is dotted with traditional farmhouses, you will find wells that have been in continuous use for generations. Today, even with mains water supplied by the Water Services Corporation, many property owners continue to use their wells for irrigation, cleaning, and other non-potable purposes. A functioning well can significantly reduce your water bills and your reliance on the mains supply, making it both an economically and environmentally sensible asset to maintain.
Over time, wells can deteriorate. The internal stone lining may crack, crumble, or become dislodged. Mortar joints between the stones can erode, allowing soil or debris to infiltrate the stored water. The well shaft itself may develop structural weaknesses. Sediment, organic matter, and mineral deposits can accumulate at the bottom, reducing the well’s storage capacity and affecting water quality. At Xmun Projects, our well repair service covers the full range of work needed to bring a neglected or damaged well back to full function. This includes pumping out and cleaning the well, removing accumulated sediment and debris, inspecting the internal masonry for damage, repointing mortar joints with appropriate lime-based or hydraulic lime mortars, replacing or repairing damaged stone blocks, and applying waterproof renders or coatings to the interior walls where needed to prevent leakage and contamination.
Many of the wells we work on are part of historic properties and have been in place for a very long time — in some cases, several hundred years. These structures were built using traditional techniques: hand-cut limestone blocks, lime mortar, and often a lime-based waterproof plaster known locally as “deffun,” which was traditionally made from a mixture of lime, crusite (crushed pottery or tiles), and other aggregate materials. This traditional waterproofing render is remarkably durable and has kept wells functional across generations. When restoring a historic well, we take care to use materials and methods that are compatible with the original construction. This means using lime-based mortars rather than cement, respecting the original stone coursing, and where possible, applying traditional or traditionally-inspired waterproof renders. Our aim is always to preserve the integrity of the historic structure while ensuring it functions reliably for decades to come.
Before any repair work begins, we carry out a thorough assessment of the well’s structural condition. This involves inspecting the shaft walls from top to bottom, checking for signs of cracking, bulging, stone displacement, or water infiltration from the surrounding soil. We also assess the well head — the opening at ground level — which may have its own issues, such as a damaged or missing cover, crumbling stone surrounds, or an unsafe access point. The channelling system that directs rainwater from the roof and courtyard into the well is also checked, as blockages or breaks in the channels will prevent the well from filling properly. Based on this assessment, we develop a clear scope of work and provide you with a detailed quotation before any repairs begin.
The most frequent issues we encounter with traditional Maltese wells include the following. Silt and debris accumulation is almost universal in wells that have not been cleaned for some time. This is resolved by pumping out the water, manually removing sediment, and flushing the well before refilling. Cracked or eroded mortar joints between the lining stones are repaired by raking out the old mortar and repointing with a compatible lime mix. Damaged or missing stones in the well shaft are replaced with matching limestone blocks and properly bedded and pointed. Failed internal waterproofing — where the original deffun render has broken down — is addressed by applying a new waterproof lime render or, in some cases, a modern cementitious waterproofing system that is compatible with the existing masonry. Blocked or broken rainwater channels are cleared, repaired, or re-routed to ensure efficient water collection. Unsafe or deteriorated well heads are rebuilt or repaired, and secure covers are fitted to prevent accidents and keep out debris and animals.
While many property owners are happy to use their wells in the traditional manner — drawing water with a bucket or a simple pump for garden irrigation — others want to integrate their well into a more modern water management system. We can help with this as well. This might involve installing a submersible pump and pressure system to deliver well water to garden taps, toilet cisterns, or washing machine connections, reducing mains water consumption. We can also install filtration systems where the water is intended for uses that require a cleaner supply. If you are building a new property or renovating an existing one, we can incorporate the well into the overall plumbing design so that rainwater harvesting becomes a seamless part of your daily water use. Given Malta’s water scarcity and the rising cost of mains water, this is an investment that pays for itself over time.
If you have a well on your property that needs attention — whether it is a simple clean-out, a structural repair, or a full restoration — we are ready to help. Contact Xmun Projects Ltd. on +356 7906 4535, email info@xmunprojects.com, or send us a message on WhatsApp. We will arrange a site visit to inspect the well, discuss what is needed, and provide a clear, honest quotation. We serve properties across Gozo and Malta.
