Product Description

This product is delivered directly from the supplier, lead times vary.

 

The Clearwater 9,150 Litre Shallow Dig Cesspool provides a dependable solution for the collection and storage of sewage, surface water, veterinary and animal waste, firefighting water reserves, and rainwater harvesting. Manufactured from durable Glass Reinforced Polyester (GRP), this low-profile cylindrical tank is designed to reduce excavation requirements, making off-mains drainage installations faster, more cost-effective, and easier to complete.

Its shallow dig design makes it particularly suitable for sites where deep excavations are undesirable or impractical. Designed in accordance with BS 6297, the Clearwater 9,150L Cesspool provides a robust, long-lasting storage solution for a wide range of domestic, commercial, and agricultural applications.

Cesspools are designed solely for the storage of wastewater and require periodic emptying by a licensed tanker. Optional high-level alarms are available to provide audible and visual notifications when the tank approaches capacity, helping to prevent overfilling and maintain efficient operation.

Important Installation Information

Cesspools are intended for storage only and must be emptied at regular intervals by a licensed tanker. High-level alarms are available to provide both visual and audible warnings when emptying is required.

When planning an installation, consideration should be given to:

  • Adequate tanker access for future emptying
  • Positioning at least 7 metres from any dwelling
  • Ideally locating the tank at least 10 metres from nearby watercourses
  • Site ground conditions and accessibility
  • Compliance with Building Regulations and Environment Agency requirements

Please note that current Building Regulations generally require a minimum cesspool capacity of 18,000 litres for a two-person domestic dwelling, therefore larger capacities may be required for residential installations.

 

Why Choose a Shallow Dig Cesspool?

The Clearwater Shallow Dig range is designed to minimise excavation depth and reduce installation costs while maintaining excellent storage capacity. This makes it an ideal solution for sites with difficult ground conditions or where traditional deep excavations are not practical.

FAQs

From choosing the right treatment plant to installation, maintenance and UK regulations, we've answered some of the most common questions to help you find the right solution for your property.

What is the difference between a septic tank and a sewage treatment plant?

A septic tank separates solids from wastewater before allowing the liquid to drain into a suitable drainage field. A sewage treatment plant goes a step further, using biological processes to treat wastewater to a higher standard before discharge. Sewage treatment plants are often the preferred choice where improved treatment performance is required.

What size sewage treatment plant do I need?

The correct size depends on the number of people your property is designed to accommodate, the expected wastewater flow and the type of property. Sewage treatment plants are commonly rated by Population Equivalent (PE). It's important to select a system with sufficient capacity to handle your property's requirements. Our team can help you choose a suitable system.

Do sewage treatment plants need electricity?

Most sewage treatment plants require electricity to operate components such as air blowers, pumps or control systems. However, power consumption varies depending on the manufacturer and model. Some systems use low-energy technology to help minimise running costs. Always check the individual product specifications before purchasing.

How often does a sewage treatment plant need emptying?

Sewage treatment plants require periodic desludging to remove accumulated solids. This is commonly carried out at least once a year, although the frequency depends on the system, usage and manufacturer's recommendations. Regular servicing and maintenance are also essential to maintain performance and help prevent costly breakdowns.

Do you supply replacement parts for sewage treatment plants?

Yes! At Direct Drainage, we supply a wide range of sewage treatment plant spare parts, including air blowers, diaphragms, filters and other essential components. Whether you're carrying out routine maintenance or replacing a faulty part, our team can help you identify a suitable replacement for your system.

Do you stock all tanks and sewage treatment systems?

We do not stock tanks and treatment systems as standard. These are supplied directly from the manufacturer. The lead times of these systems will vary. If you need an accurate delivery date, please contact us on 01388 537050.

Are your prices inclusive of VAT?

It is important to note that all prices listed on our website exclude VAT. VAT will be calculated at checkout.
