Water Schemes

W.J.Hatt has been installing water mains and borehole supplies for over 50 year, during which time we have laid many hundreds of miles of underground pipe. We carry out work for farms, estates, studs, racing stables, schools, as well as private houses for both mains connections and boreholes.

The company has always specialised in laying underground pipes using trenchless technologies. Wherever possible and practical we lay all our underground pipe using either a mole plough or thrust mole, both of which dramatically reduce ground surface disruption and the subsequent reinstatement costs. We offer a full design and installation service.

We can also provide service location for underground pipes and cables, in combination with stopping leaking water from burst pipes for both foul and storm water drainage, along with water pipes.

Mole plough (2004) #1

Mole plough (2004) #2

Mole plough (2004) #3

Mole ploughing allows huge quantities of pipe to be laid at exactly the correct depth incredibly efficiently and with very little above ground disruption. Unlike trenching machines it does not mix the layers of soil and leave a subsoil trench mark behind.

Thrust mole (2010)

Thrust moling offers a range of advantages over trenching. In particular the lack of reinstatement required is key to the speed and high quality of our work.

Trenched water pipe (2009)

Where mole ploughing or thrust moling isn't practicable we use a range of excavators to carry out trenching work for the installation of multiple pipes, or those with a large bore.

Internal Plumbing

Our highly experienced staff can integrate and set up new supplies into a full range of internal systems.

Further Information

W.J.Hatt Limited have been specialising in underground pipe installations for our 75 years of trading, over which time we have amassed a huge wealth of experience in overcoming difficulties that come with the work. The thrust mole allows us to tunnel under roads, concrete, and paving without excavating at the surface. This allows underground pipe to be installed while roads and work areas remain open to traffic and machinery. Reinstatement costs are also kept to a minimum as small holes are only dug every 10-15m. Traditionally, leaking water from a burst pipe is stopped by excavating down onto the suspected area once a service location has been carried out. The downside to this is that under concrete or tarmac or in poor ground the water rarely appears close to its source, and a very time consuming game of burst pipe battleships ensures. Using the thrust mole, these water leaks can often be easily circumnavigated much more cost effectively by installing new underground pipe which bypasses the site of the leak, and removes the entire section containing the burst pipe.

The mole plough allows us to install up to 150m lengths of underground pipe between each joint. As surface disruption is minimal and there's no excavating or backfilling involved the installation period is relatively fast. Once set up is complete a single 150m of 63mm pipe can be installed in as little as 20-30 minutes. To do this with a 6 ton excavator would take a full day. The mole plough can also be offset behind its tractor unit so that underground pipe can be installed along the edges of road verges. This means roads are only out of action for very short periods of time, rather than being closed for days on end whilst traditional excavation occurs. As a TAPPS 5 approved firm we are also able to liaise directly with Thames Water and certify our own pipework, which means there is no need for inspectors to have to visit sites before holes and trenches can be backfilled, or indeed allow the British weather to backfill them before the inspection occurs.

Our experienced teams of water engineers have become highly proficient at finding and repairing burst pipes. Thankfully, much of the time this is simply a matter of having the appropriate tools, fittings and excavator. However, more complicated sources of leaking water can stem from issues including rising ground water, inadequate drainage systems, blocked pipes, burst pipes, and choked drainage ditches. In addition to these are traditional causes for water leaks such as frost damage, age hardening of pipework, incorrect use of pressurised systems, corrosion, livestock damage and ground heave or subsidence. We would look to use our extensive experience to solve the issue such that problems are resolved permanently.
