Best Practice

The Best Practice series covers an array of topics, from initial drainage installation set by on-site groundworkers, to septic tanks and cesspits.

We offer advice on all the necessary dos and don’ts, with best practice information for maintenance, installation and problem prevention. We aim to equip you with knowledge, so that you can reduce the risk of drainage disasters adversely affecting staff, customers, tenants, patients, families — and your business.

These Best Practice Guides give an insight into relevant legislation such as the septic tank sewage treatment plant legislation implemented as law from 1st January 2015, and more.

Each guide offers details specific to the sector or the topic it covers, so that you’re able to put in place a plan that works for you.

Drainage guide: new builds

To avoid later inconvenience in any new build, the property’s drainage should be future-proofed as far as possible. Find out what that means in this guide which also provides information about the new model of SuDs (sustainable drainage systems) and about pre-existing systems.

Disposal of fat, oil and grease: a guide for the food industry

Many of our existing sewers were originally designed for a Victorian lifestyle, and are unable to cope with 21st century waste habits. Fat, oil and grease (FOG) cause around 80% of sewer blockages, and the effect of FOG in the sewers is evident in the increasing number of fatbergs our drainage engineers tackle daily. Food service establishments (FSEs) dominate many high streets, so making sure the staff understand how to dispose of FOG is crucial to preventing this problem. Businesses who disregard it can face criminal prosecution.

septic-tank-bps-web-imageSeptic tanks: a guide for property owners

Most properties are connected to the public wastewater system, but any that are not will require a septic tank. Septic tanks collect waste and wastewater, and have to be emptied and cleaned regularly. It is the property owner’s responsibility to maintain the tank and this guide explains how best to do that.

What you should and shouldn’t do when installing a new drainage system. Incorrect installation can mean substandard drainage performance, damage to structure and environment, not to mention inconvenience for the property owner.

Hospitals operate around the clock, so it is essential that their drainage systems do too. A blocked drain in a busy hospital can cause huge disruption to normal operations, from the closures of wards to whole departments. Hospitals need to be especially vigilant to ensure that users treat the wastewater system properly. This best practice guide for healthcare looks at the implications drain and sewer blockages can have on the NHS and other similar environments.

distribution-image-1Logistics and Distribution

Distribution and warehousing sites often expand rapidly with business growth, but the drainage system may be neglected, or left struggling to cope with the additional wastewater traffic. Some drains may even be physically ‘lost’ over time. Many companies follow standards such as ISO 14001, which requires an environmental management policy. We can help by providing drainage asset information and maintenance programmes to avoid pollution incidents.

surface-water-image-1Surface Water and Flooding

Surface water, also known as storm or rain water, is channelled into roof gutters, downspouts and road gullies which flow into surface water drains and sewers, many of which will outfall to watercourses. No single body is responsible for managing flooding, but this guide contains information about different types of drainage and how to minimise your flood risk.

reline bp guideA Guide to Drainage Relining

Today, our engineers repair drains and sewers without having to excavate. The repair process, known as CIPP (Cured in Place Pipe) lining, involves relining the damaged pipe with a special liner. CIPP minimises the disruption of drain renovation to people, traffic, businesses and the environment.


pg56Robotic Cutters

When drain and sewer pipes become blocked, either through inadequate maintenance or obstructions like cement, concrete, tree roots and the like, robotic cutters are essential weapons in our armoury. This technology allows us to rid the pipe of the offending material, without causing major disturbance: for example, we are currently removing a gigantic ‘concreteberg’ from the sewers of London.


Production and Manufacturing

Regular maintenance of drainage assets ensure that businesses can run operations as normal. With production and manufacturing plants, there is no ‘one-size fits all’ drainage system. Depending on the nature of your operating plants, you may need special methods of cleaning and disposing of your drainage.

‘Drainage’ here refers to all surface water, foul waste and process effluent pipework.

We understand the massive variation of business types within the Product and Manufacturing industry, and this best practice guide offers extensive information on controlling and maintaining your drainage assets.
