Sewage Treatment Plant Servicing in Woldingham

Servicing, repairs and desludging for treatment plants at houses, outbuildings and rural properties in and around Woldingham.

Woldingham’s housing has been changing for years, with smaller homes replaced by larger ones on the same plots. When a property like that sits beyond the reach of the sewer, a modern sewage treatment plant is usually what goes in alongside it. Plants also turn up at converted farm buildings, stables and bigger homes on the edges of the parish.

Every treatment plant has moving parts: a blower, diffusers and often a pump and control panel. On the chalk of the North Downs, most of them discharge into the ground, so the water they release needs to be properly treated before it soaks away towards the groundwater. When one of those parts fails, the plant can stop treating long before anyone notices a smell or hears an alarm.

Our engineers service the main makes, carry the parts that fail most often, and can remove sludge on the same visit. Each visit ends with a written report, which is useful proof that the plant has been looked after if you ever sell.

What's included

What our engineers look at

Each visit follows a full checklist and ends with a written record.

  • High-level alarm

    The alarm is tested so it will warn you if the plant starts to back up.

  • Baffles and pipework

    We check the baffles, inlet and outlet are clear and undamaged, so waste moves through the chambers properly.

  • A written service record

    You get a record of the visit and our advice, handy for your files or when you sell the property.

  • The final effluent

    We look at what’s leaving the plant, which is a quick guide to whether it’s treating properly.

  • Sludge levels measured

    We measure the sludge and arrange desludging when it’s due, often on the same visit.

  • Blower and air supply

    We check the blower is running correctly and that air is reaching the diffusers, because that’s what keeps the bacteria working.

Repairs and desludging

01
A Clearmasters service van

Protected downland around Marden Park

Woldingham lies within the Surrey Hills National Landscape, much of the village is Green Belt, and the woods and chalk grassland of Marden Park form part of a Site of Special Scientific Interest. Putting in a new plant or drainage field here can involve more planning than it would in an ordinary garden.

Keeping an existing plant in good order is the easier route. A yearly service, prompt repairs and regular desludging keep it within the General Binding Rules and help avoid disruptive work. If a replacement is unavoidable, we can advise on treatment plant installations.

Desludging

Every treatment plant builds up sludge, and it needs removing before it goes beyond what the plant can hold, usually at least once a year. Leave it too long and solids can carry over into the final chamber and out to your drainage field or watercourse.

We can desludge on the same visit as your service, using our own tankers.

Questions answered

Treatment plant questions

Do I need planning permission to replace a treatment plant in Woldingham?

A like-for-like swap often doesn’t, but a new system, a bigger plant or a new drainage field may. Woldingham is in the Surrey Hills National Landscape and the Green Belt, so check with Tandridge District Council before work starts. Building regulations approval is normally needed as well.

Do you install new treatment plants?

Yes. If your old plant or septic tank needs replacing, we can quote for a new treatment plant and, if needed, a new drainage field.

Can you get my plant working on the same visit?

Often, yes. Our engineers carry the most common parts, such as blowers and pumps, so many repairs are done there and then. For less common parts we’ll order them and come back.

How often should a plant serving a large Woldingham house be serviced?

At least once a year, and a busy household may need sludge removed more often than the plant’s minimum. Big homes with several bathrooms and regular guests can push a plant close to its design load. We’ll compare the size of your plant with how the house is used and suggest a sensible schedule.

My plant smells. What does that mean?

A healthy plant shouldn’t smell much. A strong smell often means the blower has stopped and the bacteria have died off, or the sludge is overdue for removal. Call us and we’ll check it.

My treatment plant alarm is going off. What should I do?

Cut your water use right down and call us. Don’t switch the plant off unless it’s unsafe. Most alarms mean a blower, pump or float has failed, and we can usually find the fault on the first visit.
