pollution prevention: why drain mapping will help
While your drains and sewers may be out of sight, we want to help you ensure they are never out of mind!
As you are aware it’s your responsbility as a business not to cause pollution or allow pollution to enter the environment be it by air, water or via the ground. We know that knowledge and understanding facilitates good decisions and this statement is particularly applicable to drains. Drains are hidden from us and usually problems only become visible when they fail. Resulting in the often unpleasant and costly consequences to your pocket, reputation and the Planet.
At The Little Planet Protection Company we believe that a bit of prior planning and preparation can make all the difference. And because of this we offer a complete site drain mapping service plus a little extra. As well a mapping your drains we also reference them with accompanying explanatory notes and produce a specific drain asset maintenance manual.
This full service enables those who carry the responsibility, both now and in the future to have the site knowledge and information tools to protect your site and to keep the environment safe.
site sewer connectivity plans
Accurate Site Sewer Connectivity Plans and understanding of their maintenance and control needs are compliance critical to ensure your premises and the environment are protected. That’s why drain plans from The Little Planet Protection Company can are undertaken with full GPS Surveys and AutoCAD drain layered .dwg and a drain asset manual deliverables.
Sewers are designed and installed to move fluid this can also means they are the perfect pollution pathways for contaminated fluids to leave your site and to enter the wider environment.
our best practice advise
At a very basic level the Environment Agency issued guidance requires that you have an accurate site sewer plan and that it is available for site use. Your drain plans should be clearly marked and colour differentiated from the sewer duty i.e. Foul, Storm and Trade Effluent (if present).
In addition to the basic guidelines we recommend the following;
1. Manholes and other asset are appropriately referenced for general identification purposes. The Environment Agency recommend that your manhole covers are marked as to their duty including a flow direction indication. We can do all this for you.
2. Drain connectivity pathways are confirmed – this prevents misconnections and resulting environmental pollution damage.
3. Drain assets are known and identified to ensure they are appropriately managed to meet issued guidelines and manufacturer maintenance recommendations e.g. where your oil separator(s) are, their size, and classification type.
4. That you understand how your sewer asset functions. This is particularly important with *SuDS design as there will likely be attenuation areas, flow controls, containment closure valves and oil or vortex separators. SuDS designs have a wide range of above and below ground “tools” that must be understood for their correct maintenance, compliance and functionality.
5. Your sewer maps should be up to date, accessible and displayed at critical spill response stations. This enables your spill responders to contain and correctly stop the pollution pathway.
6. You have a readily accessible off-site copy of your site drain plan (cloud). This can then be easily issued to the emergency services in the event of an incident. The Fire Service will require these details to assist with their fire plan risk assessment.
7. Sewer maps should be part of your IOS14001 and EMS systems along with up to date service record logs and O&M manuals for each asset.
