Cesspits and Septic Tanks

Septic Tanks

The majority of the sewage from  homes and businesses passes directly into drains and sewage pipes, where it is transported to central treatment plants. However, not all properties are connected to the mains sewer, particularly older properties and those in rural areas. In that case, the sewage from your home will flow directly into a septic tank, sewage treatment plant or cesspit that is installed outside your property.

Your septic tank may not always be at the forefront of your mind, but there are a number of factors you must consider to stay on the right side of the law and keep your septic tank working efficiently.

How does a septic tank work?

Rather than flowing into the drain, through the sewage pipe and on to a central treatment plant, the sewage travels directly from your property to the septic tank. There, the solids are broken down by a bacterial action and must be removed periodically. The wastewater is treated and semi-purified before it passes into a soakaway or leach field where it is dispersed into the surrounding soil.

Our septic tank services

  • Septic tank maintenance – Our septic tank engineers are experienced in making repairs to existing tanks, including the replacement of associated drains and access covers. We also perform essential maintenance to remove blockages and avoid odour issues and backups.

  • Septic tank cleaning – We use high-pressure water jets to keep pipework, tanks and soakaways clean and ensure your tank is in excellent working condition.  

  • CCTV surveys – We also use CCTV technology to identify any faults there may be with your septic tank and find the most appropriate, cost-effective fix.     


Properties that are not connected to the mains sewer can choose to remove the waste that’s produced in a number of different ways. Septic tanks, sewage treatment plants and cesspits are all potential options. Unlike septic tanks and sewage treatment plants, a cesspit does not treat the sewage in any way; instead, all the sewage is held in the tank. That means cesspits have to be emptied much more frequently. They are also more prone to clogging, so regular cesspit maintenance is an essential consideration.

Cesspit maintenance

We offer a cesspit maintenance service which we undertake once the cesspit has been emptied. That will allows us to give the cesspit a full clean, service and repair as required. As cesspit pipes are prone to clogging, we also give it a good wash with our high-pressure water jets to remove any blockages and make sure everything is flowing freely.

Rainwater Harvesting

Rainwater Harvesting Systems & Installation

With environmental issues and water usage a constant concern in Spain, more and more homeowners are exploring the potential of rainwater harvesting to optimise water usage and reduce their reliance on mains water. Spanish summers are getting hotter and hotter, so-called ‘grey water’ systems have the potential to reduce domestic mains water usage by 40 to 50 per cent and cut your water bill by the same amount.

What can rainwater be used for?

Rainwater harvesting creates an additional supply of water that can be used in the garden to water plants and vegetables, wash the car, clean patios and decking. It can even be used in washing machines and to flush toilets. With so many potential uses, clear environmental benefits and significant savings to be made, it’s not surprising that so many new-build developments and major refurbishment projects are including rainwater harvesting installations in their plans.

There are a number of different rainwater harvesting installations that can be used to save, store and use rainwater. They can be broken down into three categories:

  • Basic rainwater systems – At their very simplest, rainwater harvesting installations include stands and round water butts with a capacity of up to 400 litres. We can also provide rainwater tanks with a greater capacity, as well as free-standing and submersible water pumps.

  • Above-ground rainwater systems – Above-ground rainwater harvesting systems are known for their ease of installation and low cost. Their capacities can range from 800-litre plastic tanks all the way up to 100,000-litre steel tanks for commercial and industrial units.

  • Underground rainwater systems – If the amount of space you have above ground is limited, an underground rainwater harvesting installation can be used. The disadvantage of this system is the cost, with excavation work having to be carried out, and the fact that a pump will have to be used to distribute the rainwater from the tank.

We can supply and install cost-effective rainwater harvesting systems to help you gather and reuse rainwater. Our professional, highly trained team can provide as much advice and assistance as you need, from recommendations on tank size to the most appropriate location for the installation.

We also provide a proposal for the work and all the costs upfront, so you won’t receive any nasty surprises further down the line. Get in touch to discuss your rainwater harvesting installation requirements today.
