Watermains in Gerrards Cross: Revolutionising Utility Installations

Watermains Replacement

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 Gerrards Cross and across Buckinghamshire. If you’re experiencing these issues, you might be searching for “water line repair” or considering lead pipe replacement options.

Watermains replacement in Gerrards Cross has seen major changes in recent years, driven by the introduction of modern moling and drilling machines. In a town where space is tight and streets are always in use, traditional excavation methods have become less practical. Installing or replacing water mains in such a densely populated and historic environment demands smarter, cleaner, and more efficient approaches.

That’s where EPS Trenchless Installations comes in. We specialise in modern “no-dig” trenchless technology that minimises surface disruption while delivering faster, long-lasting results.

Whether you’re replacing ageing pipes or planning a new watermain connection, EPS delivers dependable solutions using industry-leading techniques in moling and horizontal directional drilling.

What is Moling?

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.

Benefits of Impact Moling for Water Mains Replacement

Installing or replacing water mains in Gerrards Cross’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:

Minimal Surface Disruption

The trenchless nature of impact moling preserves surface infrastructure, particularly crucial in Gerrards Cross’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.

Cost-Effective

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.

Time Efficiency

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.

Environmental Preservation

By avoiding extensive excavation, impact moling helps protect Gerrards Cross'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.

Moling: How it works?

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.

Addressing Water Supply Issues

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.

Pipe Materials and Sizes

When it comes to water pipe replacement, various materials have been used in Gerrards Cross, 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.

Moling vs Directional Drilling

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.

Conclusion

Impact moling has revolutionised utility installations in Gerrards Cross and across Buckinghamshire, delivering exceptional efficiency while keeping the cost competitive. The town’s historical significance and varied soil conditions make moling an ideal choice for infrastructure upgrades.

Gerrards Cross History

Gerrards Cross takes its name from the Gerrard family—landowners in the 14th century—and the traditional cross that once stood at the main crossroads in the area. It grew up as a coaching stop along the London–Oxford route, with inns serving travellers. The arrival of the Metropolitan Railway station in 1906 sparked rapid suburban development, transforming it into an affluent commuter settlement. Today, Gerrards Cross blends historic charm with modern residential appeal, boasting elegant Edwardian architecture and leafy avenues.

Geography

Perched atop the southern slopes of the Chiltern Hills, Gerrards Cross lies on Lambeth and London Clay with shallow chalk capping and extensive glacial gravels: shallow silty calcareous soils over chalk (rendzinas) with occasional pockets of deep loam. These soils can be stony, seasonally waterlogged, and prone to surface instability—making open-cut trenching disruptive. Trenchless techniques like moling and directional drilling offer a precise, low-impact solution, preserving the aesthetic and historic environment.
