O M D I

Off-Mains Drainage Installers
OMDI is a family-run business, based near Pontefract, which was established in 2007, with over 20 years' experience in the industry. Our expert team installs over 150 drainage systems per year throughout our area. We provide an expert, personal and dedicated service to all our customers for each installation, ensuring the highest standards are met every time.

Our personal service thrives upon a dedication to the customer, and keeping every step of the process in-house, never outsourcing works to contractors. A full turnkey solution takes care of you from the very start of the project right through to the final touches of the installation, including providing experienced advice, a thorough survey, supplying all parts and products, expert installation, de-commission of any old tanks and the final handover to the client.

Septic Tank Installation
With over 20 years of experience in the industry, OMDI are trusted experts in the design, installation, and maintenance of septic tanks for both commercial and domestic properties UK-wide. Septic tanks offer an efficient and environmentally friendly way of disposing of wastewater without using public sewers.

Whether you’re a business looking for a greener way of processing and recycling your wastewater, or a homeowner with a property that is not connected to the main sewage pipes, our team can help you find the most cost-effective solution.

Soakaway Design
With over two decades of off-mains drainage experience, we pride ourselves on our drainage expertise and services. Our in-house team are specialists in soakaway design and installation for both commercial and domestic properties throughout the UK. We install some of the more common installations including septic and mound soakaways, drainage fields, hydro brakes and water crates with attenuation tanks.

We also provide a full land-drainage service, including both assessments and percolation tests, none of which is outsourced. By completing these tests, we can ensure that the area is totally suitable for the installation of a soakaway for your property. These comply with building regulations and SUDS (Sustainable Drainage Systems).

Surface Water Drainage
If you are finding that the area around your property appears to be flooded due to excess surface water, then you need one of our surface water drainage systems.

Here at OMDI, we have more than two decades of experience in the design and installation process of all off-mains drainage systems. Our experienced and dedicated team constantly aim to provide all our customers with an expert solution, selecting the best result for draining both excess rain and ground water on all domestic and professional properties, constantly delivering the best possible results, all whilst maintaining our fantastic customer service.

Grey Water Systems
Grey water is the wastewater produced from all households and office buildings, such as bath, shower, sink and washing-machine water. With over two decades of experience, we have designed and installed a countless number of irrigation systems that take the grey water and utilise it so that it never goes to waste, and can be used for a productive and beneficial purpose. At OMDI, we can design and install grey water systems at both commercial and domestic premises across the UK, to recycle the wastewater and put it to good use.

Drain Survey
When buying a house, it is both extremely crucial and common practice to complete a drain survey. Blocked drains are notoriously a huge inconvenience, causing all manner of health hazards and interrupting the smooth operation or your home or business. If you want to prevent these issues before they can make themselves known, then you should definitely consider arranging a drain survey with our team at OMDI.
