Off-mains drainage done properly. We design, supply and install fully compliant sewage treatment plants and foul water pumping stations.
If your property is not on mains drainage, your treatment plant or pumping station is one of the most critical pieces of infrastructure you own. Getting it wrong is expensive, messy, and increasingly heavily regulated.
We design and install fully compliant sewage treatment plants and foul water pumping stations across Yorkshire, working with leading manufacturers and to the General Binding Rules set out by the Environment Agency. Every installation is signed off with the paperwork you need for building control and future house sales.
We also handle full septic tank replacements where older tanks no longer meet regulations, and can set up an ongoing servicing schedule so your system stays compliant and trouble-free.
"Called DMI out of hours for a badly blocked drain and they were brilliant. Quick to arrive, sorted the problem in no time, and the price was very fair and very reasonable for an emergency call-out. Could not recommend them more."
