Why should I have my Sewage Pump or Sewage Treatment Plant regularly maintained?

If your property is located in a low-lying area or sits far from the main sewer network, having a reliable sewage pump, sump pump, or sewage treatment plant is essential for the safe and efficient management of wastewater. These systems play a vital role in protecting your property from drainage issues, flooding, and costly damage — but regular maintenance is key to keeping them operating at peak performance.

Over time, wastewater systems naturally accumulate oils, grease, fats, sludge, and other waste materials that can cause blockages, reduced efficiency, unpleasant odours, and even complete system failure if left untreated. Even the highest-quality sewage pumping systems and treatment plants require routine servicing to ensure long-term reliability and compliance with environmental standards.

At CPD Waste Water Ltd, we provide professional sewage pump servicing, sump pump maintenance, and sewage treatment plant servicing for domestic and commercial properties. Our experienced engineers carry out thorough inspections, cleaning, fault diagnosis, and preventative maintenance to help reduce the risk of unexpected breakdowns and expensive repairs.

We recommend servicing your wastewater system every six months to maintain optimal performance and extend the lifespan of your equipment. Regular maintenance allows potential problems to be identified early, helping to prevent emergency call-outs, minimise downtime, and keep your drainage system running efficiently all year round.

Whether you require routine maintenance, emergency repairs, or expert advice on your drainage system, CPD Waste Water Ltd delivers reliable, cost-effective wastewater solutions tailored to your property’s needs.

Regular sewage pump maintenance and sump pump servicing should always be carried out by a qualified and experienced professional. These systems are essential for effective wastewater management, flood prevention, and the safe operation of your property. Without routine maintenance, sewage pumps and sump pumps can become blocked, fail unexpectedly, or operate inefficiently, leading to costly repairs and potential property damage.

At CPD Waste Water Ltd, we provide comprehensive sewage pump service, sump pump maintenance, and wastewater system inspections for both domestic and commercial properties.

Routine pump station maintenance and sewage pump servicing can significantly reduce the risk of breakdowns, improve system efficiency, extend the lifespan of your equipment, and help avoid expensive emergency repairs.

We recommend servicing your sewage pump system or sump pump system at least every six months to keep your wastewater system operating at peak performance throughout the year.

Whether you require planned preventative maintenance, emergency pump repairs, or ongoing wastewater management support, CPD Waste Water Ltd provides dependable, professional drainage solutions tailored to your property’s needs.

Your sewage system, sewage pump, and sewage treatment plant are designed to safely process human waste and toilet paper, both of which break down quickly within the system. However, many everyday household items — including products labelled as “biodegradable” or “flushable” — can cause serious drainage and pump problems when flushed down the toilet.

These materials often fail to break down properly, leading to blocked pipework, damaged pumps, sewage backups, and expensive emergency repairs. In many cases, avoidable blockages are one of the leading causes of sewage pump failures and drainage system breakdowns.

To help protect your wastewater system and avoid costly call-outs, never flush the following items:

• Wet wipes and cleaning wipes (including “flushable” wipes) 
• Sanitary products such as tampons and sanitary pads 
• Paper towels and cleaning cloths 
• Cotton buds (Q-tips) 
• Dental floss 
• Nappies and diapers 
• Grease, fats, or cooking oils 
• Disposable gloves, masks, or hygiene products 

Even if these products appear harmless, they can accumulate inside pumps, pipework, and sewage treatment systems, eventually causing blockages and equipment failure.

A simple rule to remember is:

If it doesn’t break down as easily as toilet paper, it should go in the bin — not the toilet.

Taking a few preventative measures can significantly reduce the risk of blocked drains, sewage pump damage, flooding, and emergency breakdowns. Combined with regular sewage pump servicing and sump pump maintenance, good waste disposal habits will help extend the lifespan of your wastewater system and keep it operating efficiently.

At CPD Waste Water Ltd, we provide expert drainage solutions, sewage pump servicing, pump maintenance, and wastewater system repairs for domestic and commercial properties across the South East. If you are experiencing recurring blockages or pump issues, our experienced engineers are here to help.

In short — it’s best to avoid excessive use of bleach and harsh chemical cleaners if your property has a sewage treatment plant or septic system.

Sewage treatment plants rely on naturally occurring bacteria to break down waste through a biological treatment process. These beneficial bacteria are essential for keeping your wastewater system operating efficiently and safely. Strong chemicals such as bleach, disinfectants, antibacterial cleaners, and harsh drain products can kill this bacteria, disrupting the treatment process and potentially leading to poor system performance, unpleasant odours, drainage issues, or even complete system failure.

While the occasional small amount of bleach is unlikely to cause immediate damage, repeated or heavy use over time can significantly reduce the effectiveness of your treatment plant and increase the risk of costly repairs or maintenance issues.

If you have a sewage treatment plant, it’s important to choose cleaning products that are specifically labelled as:

• Septic-safe 
• Sewage treatment plant-safe 
• Biodegradable and environmentally friendly 
• Low in harsh chemicals and antibacterial agents 

These products are specially formulated to clean effectively without damaging the beneficial bacteria your wastewater system depends on.

Using the correct household cleaning products, alongside regular sewage treatment plant servicing and pump maintenance, can help:

• Improve the efficiency of your wastewater system 
• Prevent system blockages and failures 
• Reduce unpleasant odours 
• Extend the lifespan of your sewage treatment plant 
• Avoid expensive repairs and emergency call-outs 
• Maintain compliance with environmental regulations 

At CPD Waste Water Ltd, we provide professional sewage treatment plant servicing, sewage pump maintenance, and expert wastewater advice for domestic and commercial properties. If you are unsure whether your cleaning products are safe for your system or need maintenance for your treatment plant, our experienced engineers are here to help.

If your property is fitted with a sump pump, sewage pump, pumping station, sewage treatment plant, or septic tank, it is essential to ensure the system is properly maintained and that tenants understand how to use it correctly.

At CPD Waste Water Ltd, we provide expert wastewater maintenance, sewage pump servicing, and emergency drainage repairs for domestic and commercial properties throughout the South East.

The cost of replacing a sump pump, sewage pump, air pump, or other components within a sewage treatment plant can vary depending on the type of system installed and the complexity of the work required. Every wastewater system is different, which is why professional assessment is important before accurate pricing can be provided.

At CPD Waste Water Ltd, we provide expert sewage pump replacement, sump pump installation, air pump repairs, and sewage treatment plant maintenance for domestic and commercial properties across the South East.

Several factors can influence the cost of replacing or repairing a wastewater system component, including:

• The type and size of the sewage or sump pump 
• The make and model of the equipment required 
• Accessibility of the installation site 
• The complexity of removal and installation work 
• Electrical or control panel requirements 
• The condition of the existing wastewater system 
• Whether additional repairs, upgrades, or pipework modifications are needed 
• Emergency call-out or urgent repair requirements 

Because no two drainage systems are the same, it is not always possible to provide a fixed price without first inspecting the equipment and understanding the condition of the system.

Our experienced engineers can assess your wastewater system, identify any faults, and recommend the most cost-effective and reliable solution for your property. Whether you require a replacement sewage pump, sump pump, air blower, or repairs to a complete sewage treatment plant, we provide honest advice, quality workmanship, and competitive pricing.

If you are experiencing problems with your pumping station, sump pump, or sewage treatment plant, contact CPD Waste Water Ltd today. We will be happy to discuss your requirements, assess your system, and provide a tailored quotation based on your specific wastewater and drainage needs.

The running cost of a sewage pump, sump pump, pumping station, or sewage treatment plant can vary depending on the size of the system, how often it operates, and your electricity tariff. Modern wastewater systems are generally designed to be energy efficient, but ongoing electricity usage should still be considered as part of your maintenance and operating costs.

At CPD Waste Water Ltd, we regularly help homeowners, landlords, and commercial property owners understand the operating costs of their wastewater systems and provide expert advice on improving efficiency and reducing unnecessary energy usage.

The cost of running a wastewater system can depend on several factors, including:

• The size and type of sewage pump or air compressor 
• Whether the system runs continuously or on a timed cycle 
• The number of pump activations per day 
• The age and efficiency of the equipment 
• The pumping distance and discharge height 
• The amount of wastewater being processed 
• Your electricity tariff and energy supplier rates 

A small domestic sewage treatment plant with a continuously running air compressor typically uses between 80–100 watts of electricity. Based on the latest UK electricity rates of approximately 24.67p per kWh under the current Ofgem energy price cap, this equates to an estimated running cost of:

• Approximately £0.50–£0.65 per day 
• Around £15–£20 per month 
• Approximately £180–£240 per year 

Current UK electricity unit rates are based on the latest Ofgem energy price cap figures for 2026. 

The running cost of a sewage pump or sump pump can be more difficult to estimate accurately because it depends heavily on:

• How frequently the pump activates 
• The size and power of the pump 
• Pump efficiency 
• Head height and pumping distance 
• Water usage within the property 
• The size of the pumping station or wet well 

For example, a pump that runs occasionally for a domestic property may use very little electricity, while larger commercial pumping stations with multiple daily start-ups will naturally consume more power.

Regular sewage pump servicing and treatment plant maintenance can help improve efficiency, reduce electricity consumption, and extend the lifespan of your equipment. Poorly maintained systems often work harder than necessary, leading to increased running costs and a higher risk of breakdowns.

At CPD Waste Water Ltd, we provide professional drainage solutions, pump maintenance, treatment plant servicing, and energy-efficiency advice for domestic and commercial wastewater systems across the South East.

If you would like help estimating the energy usage or running costs of your sewage pump, sump pump, or sewage treatment plant, contact our team today and we’ll be happy to provide tailored advice based on your system and property requirements.

A properly maintained sewage treatment plant should operate efficiently without producing strong or unpleasant odours. If you notice persistent foul smells coming from your wastewater system, it is often a sign that the biological treatment process is not functioning correctly and that the system may require professional attention.

At CPD Waste Water Ltd, we provide expert sewage treatment plant servicing, fault diagnosis, and wastewater system repairs for domestic and commercial properties across the South East.

Several issues can cause unpleasant smells within a sewage treatment plant, pumping station, or wastewater system, including:

• Disruption or loss of the beneficial bacteria required for biological treatment 
• Excessive use of bleach, antibacterial cleaners, or harsh chemicals 
• System overload caused by excessive wastewater entering the plant 
• Blocked pipework or restricted airflow 
• Mechanical failures or damaged components 
• Faulty air pumps, compressors, or blowers 
• Poor maintenance or missed servicing intervals 
• Build-up of sludge, grease, or waste materials within the system 

When the biological process is disrupted, untreated waste can begin to produce strong sewage odours, indicating that the treatment plant may not be operating effectively.

Ignoring foul smells from your wastewater system can lead to more serious issues over time, including:

• Reduced treatment efficiency 
• System blockages and overflows 
• Sewage pump failures 
• Environmental compliance issues 
• Costly repairs or component replacement 

Having your system inspected early by a qualified wastewater engineer can help identify the root cause quickly and prevent further damage to the treatment plant or drainage system.

At CPD Waste Water Ltd, our experienced engineers carry out comprehensive sewage treatment plant inspections, pump servicing, and wastewater system maintenance to restore your system to full working order. We diagnose faults, repair damaged components, and ensure your treatment plant is operating safely, efficiently, and in compliance with environmental standards.

If your sewage treatment plant, septic system, or pumping station is producing unpleasant odours, contact CPD Waste Water Ltd today for professional advice, servicing, and reliable drainage solutions.

Sewage pumps and sump pumps can fail for a number of reasons, but one of the most common causes of pump breakdowns is blockages created by non-biodegradable materials entering the wastewater system.

These pumps are specifically designed to handle:

• Foul wastewater 
• Human waste 
• Toilet paper 

Anything beyond these materials can lead to blocked pipework, damaged impellers, pump overloads, and complete system failure.

At CPD Waste Water Ltd, we regularly attend emergency call-outs caused by avoidable blockages in sewage pumping stations, sump pump systems, and sewage treatment plants across domestic and commercial properties.

Many everyday household products should never be flushed or disposed of through the drainage system. Common items responsible for sewage pump failures include:

• Wet wipes and cleaning wipes 
• “Flushable” or biodegradable wipes 
• Sanitary towels and sanitary products 
• Tampons and applicators 
• Paper towels and cleaning cloths 
• Cotton buds (Q-tips) 
• Dental floss 
• Nappies and diapers 
• Grease, fats, and cooking oils 

These materials do not break down quickly enough inside the wastewater system and can easily become tangled within the pump mechanism, causing blockages and costly damage.

One of the most common misconceptions is that wipes labelled “biodegradable” or “flushable” are safe to flush. In reality, while these products may eventually break down, they do not degrade quickly enough for modern sewage systems, pumping stations, or treatment plants.

As a result, they often accumulate within pumps and pipework, leading to:

• Sewage pump blockages 
• Pump overheating and motor failure 
• Reduced system performance 
• Flooding and sewage backups 
• Expensive emergency repairs 

To help avoid unnecessary repairs and extend the lifespan of your sewage pump, sump pump, or treatment plant, the rule is simple:

Only flush toilet paper and human waste. Everything else belongs in the bin.

Regular sewage pump servicing and preventative maintenance can also help identify potential problems before they lead to major system failures.

At CPD Waste Water Ltd, we provide expert drainage solutions, pump maintenance, blockage removal, and wastewater system repairs for residential and commercial properties throughout the South East. If you are experiencing recurring pump issues or drainage problems, our experienced engineers are here to help.

The General Binding Rules (GBRs) were introduced by the Environment Agency on 1st January 2015 to regulate small sewage discharges from septic tanks and sewage treatment plants in England. These rules are designed to reduce pollution, protect waterways, and ensure wastewater systems are installed and maintained correctly.

If you own a property with a septic tank, sewage treatment plant, or private drainage system, it is important to understand your legal responsibilities and ensure your system complies with current Environment Agency regulations.

At CPD Waste Water Ltd, we help homeowners, landlords, and commercial property owners assess, upgrade, maintain, and replace non-compliant wastewater systems throughout the South East.

If your septic tank discharges directly into a:

• Ditch 
• Stream 
• River 
• Brook 
• Watercourse 

then it must no longer discharge untreated sewage directly into the environment. Since 1st January 2020, septic tanks that discharge directly into surface water are no longer compliant under the General Binding Rules.

If your septic tank currently discharges into a watercourse, you must either:

Install a compliant sewage treatment plant that meets BS EN 12566-3 certification standards and produces treated effluent suitable for discharge.

Redirect the discharge away from the watercourse into a properly designed and constructed drainage field that complies with BS6297:2007 standards.

The correct solution will depend on your property, available land, ground conditions, and existing drainage infrastructure.

If you are selling a property with a private drainage system, you are legally required to:

• Inform the buyer that the property uses a septic tank or sewage treatment plant 
• Provide details of the system and its maintenance history 
• Confirm whether the system complies with the General Binding Rules 
• Upgrade or replace non-compliant systems where required 

Failure to disclose drainage system information during a property sale can lead to legal and financial complications.

Under the Environment Agency’s Code of Practice, property owners are legally responsible for:

• Choosing the correct wastewater system for the property 
• Ensuring the system is installed correctly 
• Carrying out regular maintenance and servicing 
• Preventing pollution and environmental damage 
• Ensuring sewage discharges comply with current regulations 

Poorly maintained or non-compliant systems can lead to pollution, enforcement action, expensive repairs, and environmental harm.

To remain compliant, your wastewater system must also:

• Be regularly maintained and emptied when required 
• Operate without causing pollution or nuisance 
• Discharge no more than: 
  • 2 cubic metres per day to ground via a drainage field 
  • 5 cubic metres per day to surface water from a treatment plant 
• Be installed and operated according to the manufacturer’s instructions 
• Be accessible for servicing and inspection 
• Not be located within protected groundwater source zones without approval 

In some situations, you may require an environmental permit from the Environment Agency if your system does not meet the General Binding Rules.

At CPD Waste Water Ltd, we provide expert:

• Septic tank replacements 
• Sewage treatment plant installations 
• Drainage field installations 
• Wastewater system inspections 
• Pump servicing and maintenance 
• Compliance assessments and advice 

Our experienced engineers can assess your existing system, explain your legal obligations, and recommend the most cost-effective solution to bring your wastewater system up to current standards.

If you are unsure whether your septic tank or sewage treatment plant complies with the latest General Binding Rules, contact CPD Waste Water Ltd today for professional advice and tailored drainage solutions.
