Welcome to Off Mains Drainage Consultants Ltd


Water & Waste Water Solutions

Welcome to Off Mains Drainage Consultants Ltd, We offer a range of services within our specialist sector. With over 25 years combined knowledge, You know you are in safe hands.

Off Mains, is all about those who cannot connect on the mains foul water network, or in some cases those who need to connect to mains foul water network via the extra support of a pumping station. Our services can be used by Residential, Commercial and Agricultural, Home Owners or  Home Buyers. We can survey & Investigate Foul and Surface water systems.
Septic Tanks and Package Treatment Plant Surveys are critical when buying your new home or other type of property, people can hide problems that normal surveyors can't see.

We can offer the solution to foul water disposal by designing and using supporting contractors to execute the installation of Septic Tanks, Sewage Treatment Plants, Cesspits and Pump Stations and Drainage Fields to disperse of the effluent water via the ground. We offer our design service for new or existing properties that need a new private mains sewage treatment plant for small to large developments.

By using us, we will investigate the problem, and then bring back to you a solution that's right. You ask three or four companies to come to site, and be given three or four different solutions,ideas and costs. Then where do you go, who do think is telling you or giving you the right solution? You can spend a lot of money installing or rectifying a system and this could be lost money if it fails. The design has to conform to many regulations, and be designed to serve its purpose throughout its life span.

The way we work is to find the issues, give you the solution, the design, tell you which government bodies have to be informed and if required a cost of the works. You can then send these details out to tender and everyone will be pricing for the same project and no confusing quotes. They will still need to come to site just look and confirm everything.
Once the designs have been completed, We will then come to you and go through the details so you are fully aware before you ask any other contractors to come and price for the works.

We not only offer our services in foul water, but surface water and SUDS systems, these are just as important as foul water. We work with Major Manufactures and Leading Engineers.

If you have any problems with your drainage, just call us and receive the service you need.
If you hear these words:
  • we can just dig and install a section of drainage across there in one line
  • we can install some milk crates
  • we will install a pump in your septic tank and dig a hole for a new soakaway
  • we will just pipe your septic tank to that ditch
  • we will install land drainage for your septic tank

These are just as few lines, and if you are told this you are being told incorrectly. Ask for full design Specs and where the Building Regulations Appendix H says it.

Home Buyers, don't just rely on your home survey to determine the state of your drains..... problems often don't get seen and then you are possibly facing large financial bill's to rectify them.
