Low pressure, discoloured water, unusual tastes, or unexpectedly high-water bills from leaks mean it’s time for water supply pipe replacement – especially if they’re made from lead or other ageing materials. These water supply problems are common issues faced by homeowners and businesses in Welwyn Garden City and across Hertfordshire. If you’re experiencing these issues, you might be searching for “water line repair” or considering lead pipe replacement options.
Watermains replacement in Welwyn Garden City has seen major changes in recent years, driven by the introduction of modern moling and drilling machines.

Impact moling, sometimes referred to as pipe moling or pneumatic moling, is a cutting-edge trenchless technology for installing underground utilities, including water pipes, electric cables, and fibre optic lines. It involves using a device called an impact mole. Occasionally referred as a water mole or pipe mole machine, an impact mole is a pneumatic burrowing device that creates horizontal boreholes through repetitive percussive action. Impact moling is faster and cheaper with the impact moling cost per meter being significantly lower than traditional open cut methods.
The technique is particularly effective in urban settings, where minimising disruption to roads, footpaths, landscapes, and other infrastructure is important. In more rural areas, moling with its minimal environmental impact preserves the local ecosystems, countryside, and wildlife.
Impact moling is a precise and efficient method that creates a guided tunnel through the soil for laying utilities. It is extremely useful when accessing limited spaces, as the moling equipment typically consists of a compressed air-driven pneumatic cylinder with relatively small entry and exit pits. For those considering impact mole hire, it is better to use experienced professionals who understand the intricacies of this technology.
Installing or replacing water mains in Welwyn Garden City’s urban and suburban areas using traditional trenching methods has always been a difficult task. Impact moling, as part of comprehensive moling services, offers several key advantages:
The trenchless nature of impact moling preserves surface infrastructure, particularly crucial in Welwyn Garden City’s older districts and modern urban areas, maintaining the integrity of roads, pavements, and gardens. This makes it an ideal method for domestic water main replacement and pipe replacement projects, ensuring the minimum disruption of homeowners and businesses.
Impact moling is a game-changer for water pipe repairs and replacing water supply pipes, slashing costs compared to traditional methods. With less labour and minimal reinstatement work needed, it's a faster, more budget-friendly solution that keeps disruption to a minimum. Moling contractors near me can provide competitive pricing for these services, with favourable installation rates compared to traditional methods.
The trenchless installation method of impact moling means quicker installation compared to traditional methods, reducing job timelines and inconvenience to homeowners, residents and businesses. It's especially great for quickly and efficiently replacing water main-to-house connections, with many installations, depending on the pipe length and diameter, being completed within a day.
By avoiding extensive excavation, impact moling helps protect Welwyn Garden City's local ecosystem and reduces the environmental impact of utility installations. Moling is the environmentally friendly solution among no-dig techniques for underground pipe installations, minimizing soil displacement and greatly reducing the carbon footprint of projects.
Impact moling can be used for various underground utility installation projects, including water pipe installation, electrical cable installation, and fibre optic installation. The process begins with excavating small entry and exit pits at the start and end points of the desired pipe route. The moling equipment is then inserted into the entry pit and guided through the soil using horizontal digging techniques for borehole creation.
This method is particularly useful for residential water pipe installations, typically ranging from 750mm to 1350mm below ground level. The pipe diameter that can be installed using moling techniques varies, but it’s generally suitable for smaller to medium-sized pipes. Most domestic water mains will have an 25mm or 32mm MDPE pipe installed. We can install larger pipes – please contact us for details.
If you’re dealing with old lead pipes and low water pressure, a main water pipe replacement is normally the best the solution. Using a moling machine, we can install new pipes without digging up your entire garden or driveway. This method is perfect for upgrading older smaller, iron and lead pipe sizes to modern, safer materials.
Impact moling is not only useful for new installations but also for addressing existing water supply problems. It can be used in conjunction with leak detection and pipe tracing technologies to find and fix issues such as poor water pressure or water leakage. In the case of repairing leaking pipes, on longer pipe runs, after the leak has been traced, it is sometimes better to bypass the leak with moling, thus ensuring minimal excavation and disruption to the surrounding area. This approach can lead to significant improvement in water quality and water flow.
When it comes to water pipe replacement, various materials have been used in Welwyn Garden City, including iron, black alkathene plastic and lead pipes. All of this older infrastructure is being phased out due to age of the pipes or health concerns and is being replaced with modern blue MDPE plastic pipes. Blue MDPE pipes offer durability and flexibility, making them ideal for use with impact moling techniques.
There are two main types of Trenchless Technology – Impact moling or Directional Drilling. So when it comes to installing or replacing underground pipes without digging up your driveway, garden, or car park – which is best for your property or business premises?
Impact moling is ideal for smaller-scale jobs like domestic mains water pipe replacement, electrical cable and fibre-optic cable installations, especially under lawns, driveways, or pathways and can normally be completed within a day. For long runs of over 30m Horizontal Directional Drilling is the better option especially for larger-scale projects, commercial sites and more complex installations.

Case Study: A homeowner in Welwyn Garden City was experiencing inconsistent water pressure and poor flow to their upstairs bathroom due to an aging galvanised steel mains pipe. With a beautifully maintained block-paved driveway, mature hedging, and recently planted borders, they were understandably reluctant to allow any digging works on the property. Given Welwyn Garden City’s chalk-based soil with clay top layers, traditional trenching could have caused significant disruption and long-term damage to the landscaping.
We carried out a trenchless water mains replacement using impact moling, installing a new 32mm MDPE pipe from the boundary to the internal stop tap without disturbing the driveway or garden. The job was completed neatly in less than a day, restoring full water pressure throughout the home—perfect for their newly installed boiler and en-suite shower system. The homeowner was particularly pleased that their front garden remained untouched and their investment in hard landscaping stayed protected.

Welwyn Garden City was founded in 1920 by Sir Ebenezer Howard, following his earlier experiment in Letchworth Garden City. The town was designed to combine the benefits of the countryside with the amenities of urban life, embodying the principles of the Garden City Movement. Architect Louis de Soissons was appointed as the town’s planner, creating a layout characterized by tree-lined boulevards and a neo-Georgian town centre. In 1948, Welwyn Garden City was designated as a New Town under the New Towns Act, further promoting its development. Today, it stands as a testament to early 20th-century urban planning ideals.
Located in Hertfordshire, Welwyn Garden City is situated on gently undulating land on the northern valley slopes of the River Lea. The area is underlain by a combination of plateau and river terrace drift, with soils including well-drained flinty coarse loamy and sandy soils over some gravels. These soil conditions can complicate traditional excavation due to drainage issues. Trenchless installation methods, such as moling and directional drilling, are advantageous here, minimizing surface disruption and preserving the natural landscape.
