Drainage

W.J. Hatt are an experienced septic tank and sewage treatment plant installer. We both design & install foul and storm water drainage systems of every size. These range from those needed by private houses to that of large schools and estates.

When it comes to all kinds of drainage and sewerage solutions, we are very accomplished and can:

• Install new or replacement sewage treatment systems and drainage fields (soakaways).
• Upgrade or repair failing or inadequate drainage pipe networks.
• Dredge blocked or overgrown drainage ditche or culverts.
• Install underground land drainge solutions to de-water large areas of saturated ground.

As well as being a new septic tank and sewage treatment plant installer, W.J. Hatt also carries out soakaway design and build for existing sewerage systems. We can install pumping stations and their associated pipework for untreated sewerage connections to the mains drains. The major advantage of these systems is that they do not rely on gravity. Pipework can run for miles to reach a sewerage main where required. Where gravity-fed soakaways are not appropriate, we can install smaller pumping chambers for treated sewage.

We offer a complete design and consultancy service. We have excellent connections with first-class manufacturers, such as KEE Process, Klargester (Kingspan) and Marsh Industries, ensuring that our products come directly from the best sources. This means that we can keep up to date with the latest environmental requirements, only installing systems appropriate for specific ground conditions and space restrictions.

Design and Consultancy

W.J.Hatt Ltd offer a complete design and consultancy service for new builds as well as renovations. Our wealth of onsite experience means that rather than having a design team and a separate installer they are one and the same. The main advantage to this process is that when the inevitable changes, additions, or difficulties occur during the installation these are resolved onsite without hold ups.

Foul Drainage

We can carry out repairs or replacements for all types of broken, damaged, or inappropriate pipework. We can install manholes and gully traps for both foul and waste water on new builds, as well as install any configuration of drainage, tailoring systems to your requirements. All pipework is installed in conjunction with lasers to ensure that falls are exact.

Storm Drainage

We can repair, install, or upgrade underground or land drainage to provide for your needs.

Dredging Waterways

We can dredge, enlarge, or install drainage ditches to improve flow rates and reduce risks of flooding. These open water ways often provide habitats for a huge diversity of wildlife.

Further information on drainage & flooding

Over our 85 years of trading, W.J. Hatt has always dealt with drainage problems using a pragmatic approach. The addition of modern materials, resources and pipes continues to make our drainage works ever more efficient. As flooding proves to be a pertinent issue in Britain, properly installed and maintained ditches, culverts and underground pipes become essential. Effective functionality is the driving force behind any successful flood prevention system. No amount of soakaway design will cope with storm water runoff. This is in the same way that too small a pipe will fail to carry such large quantities of water. Furthermore, drainage schemes must continue to work with as little maintenance as possible. When it comes to cost effective drainage solutions, there is simply no substitute for experience.
