Drainage...

 

Drainage is essential for most projects that we work on. Effective drainage solutions can help guide surface and foul water to the correct destination. Without proper planning problems can occur down the line. Planning is an essential part of the process we follow with any job we undertake.

 

Drainage services we offer:

 

Designed installations

If there is not an engineers design in place already, we can look at planning your drainage system for you and we will make sure that the levels work and that the system is designed correctly for you and your project. Poor drainage can cause a heap of issues from ground contamination, flooding and sewage blockages, all of which can cause damage to a building or your home.

 

Sewage treatment plants

This process is similar to the way that a septic tank works but mechanical components provide an additional method to help break down solids to produce a cleaner, more environmentally friendly effluent which can be discharged into an open water cause for example a ditch, stream or even a river. You will of course require the correct discharge licence for this, which we can organise for you.

 

Rainwater harvesting tank

Having a rainwater harvesting tank helps reduce water consumption and means you can re-use water in activities such as watering your garden, flushing toilets and washing clothes all of this helps to improve our environment. Something we all love to try and do. There are different types of rainwater harvesting tanks ranging from the simple one to include feeding one outside tap to fill up your watering can or wash your car to the more complicated installation which will feed your whole house including your toilet cisterns, washing machine and outside taps for gardens and outside use. Maybe even topping up the swimming pools!

 

Septic tanks

These are usually made out of fibreglass. They are installed if the discharge cannot go into an open watercourse, i.e. a ditch. When they are installed you also have to install an underground drainage field/soakaway system which is often constructed in a herringbone pattern from perforated pipe surrounded with shingle. The foul water flows from the home in to the septic tank through the sewer pipe. Bacteria found naturally in the wastewater work to break the solids down, and they can be emptied on a yearly basis by a sludge guzzling lorry.

 

Mains drain connections (including work required in the highway)

If you are lucky enough to be able to connect your drainage to the mains drains then this is a trouble-free way of getting rid of sewage and grey water. It also provides an efficient way of disposing of material that would otherwise be difficult to treat.

 

Cesspools/Sewage Holding Tank

If your property has no natural drainage capability, i.e. thick clay or there is just no water cause to discharge into then cesspool would be advisable. This is a holding tank that would need to be pumped out when it is full.
