Selecting the correct access covers for water networks can be a daunting challenge with factors such as operator and public safety, ergonomics and asset security requiring equal consideration.

The key to making sure that the most cost-effective solution is proposed and designed to suit each application is to ensure that there is all party early engagement at the site surveying stage.

Engaging with a reputable manufacturer who will commit to working with you through design, fabrication, delivery and offloading, and installation phases will safeguard the project programme and budget.

EN 124: 2015 Part 3-Steel has provided a clear framework for access cover manufacturers to adhere to (applicable to covers under a clear ope of one metre) with rigorous testing procedures specified.

The standard BS 9124 exists for covers over a clear ope of one metre. In the absence of a performance standard varying quality levels in production do occur resulting in low quality, unsafe products entering the market.

Meeting and exceeding the standards – the EJ approach
Working with clients to offer custom built access solutions that meet the highest standards in the world, EJ manufacture their steel range to the requirements of EN 124: 2015 -3 and BS 9124.

Load testing
In additional to applying the desired test load to the geometric centre of our covers we position ribbing in all areas under the cover identical to the geometric centre so that any point on the cover will take the required load.

Ergonomics
A key feature of our steel range of Flush Fit or Above Ground covers is the lift assistance provided by the stainles steel mechanical struts which can give a lifting effort of less than 18kg (required for lifting between 20 to 60 degrees and zero effort before and after this range).

Safety for operatives is of paramount importance to utility companies so each cover is fitted with a hand operated safety blocking system which prevents the cover from closing even in high winds.

Fall protection safety features
Various safety grids layouts are available to suit the extraction of equipment from the chamber and pass the drop test outlined in BS 9124 and take a static load of 300kg.

They are easy to open and manoeuvre with a self-blocking feature and a pivot point designed on one side which prevents the grid from 'sticking' when closing.

Retained chains are made from stainless steel and are a standard feature to aid the operator opening and closing the grid - designed to reduce the risk of back injuries and unsafe leaning into chambers.

Asset security
Our turnbuckle locking system using an M16 bolt has twice the proof stress of an M12 bolt (which is commonly used on access covers in the water networks industry) and is less likely to strip threads under normal site conditions.

A larger bolt head also aids the operator in opening the unit as dirt and debris are easily removed from around the bolt.

To enhance security on site for critical infrastructure, high security bespoke access solutions to the latest issue of the Loss Prevention Certification board LPCB Security rating 3 and 4 can be specified.

Designed to prevent unauthorised persons gaining access to key assets with third party certification offers additional peace of mind to utility providers and designers.

Delivery and offloading
Designing access solutions to allow for ease of delivery to site from small access roads is also an important consideration in the specification process.

Lifting handles are a feature on EJ covers which help minimise logistical issues delaying a project.

Conclusion
The role of the specifier, procurement officer or contractor in the selection of access covers is hugely significant.

For safety critical products there is a responsibility to ensure that the whole life performance of an installation meets the expectations of the client.

Within the water networks sector over the years, products not conforming to a performance standard have been approved resulting in low quality, unsafe products entering the market.

Working with a reputable manufacturer will guarantee you independently certified high quality products – assuring you of improved durability and products that are fit for purpose, saving money in the long run for your client.
