STANDARD MODELS & ADDITIONAL PARTS HEALTH & SAFETY PRECAUTIONS This section describes some of the potential risks and the ways in which they can be reduced. These guidelines do not set out or interpret the law – they are simply a guide to improve safety during the plant’s lifecycle. The Principal Contractor and service companies should produce their own comprehensive health and safety plan. - Page 5 Civil Installation: Installation should only be carried out by qualified and experienced professionals who understand sewage and drainage systems and their obligations under the Health and Safety at Work Act, Construction Design Management (CDM) Regulations and the Environmental Protection Act. Where necessary they should seek advice from a civil engineer.
- Page 6 Delivery to site: If there are overhead electrical cables, ensure that there is adequate clearance or that the power is turned off. If there are any obstructions to site delivery, please contact WPL to advise in advance. Installer must carry out a detailed Lift Plan prior to commencing work.
- Page 7 Tank cover: Do not leave the plant cover open for any longer than is strictly necessary. Temporary barriers and warning signs should be erected around any open covers or manways as appropriate. Blower kiosk Do not allow surface water to form a pool around –...

Page 14: What Is Wastewater Treatment
WHAT IS WASTEWATER TREATMENT? Wastewater treatment, also known as sewage treatment, is the process of removing contaminants and suspended solids from primarily household and commercial property waste such as toilets, showers and sinks. WPL DIAMOND RANGE? The WPL Diamond compact package wastewater (sewage) treatment plant is suitable for domestic and small commercial properties in all ground conditions where mains drainage is unavailable. -
Page 15: How The Wpl Diamond Works
HOW THE WPL DIAMOND WORKS Unlike the traditional septic tanks, this modern packaged wastewater treatment plant is designed with an aerated process for todays’ increased volume of water usage in everyday life. The wastewater flows into the main tank and enters directly into the bio-chamber. -
Page 16: Sizing Of The Plant Considerations
SIZING OF THE PLANT CONSIDERATIONS Water softeners Salt based water softeners can significantly reduce bacteria growth in the treatment plant and negatively affect its performance. An existing softener can be used but regeneration should be minimised and the quality of discharge monitored. A non- salt based softener should be used where possible. -
Page 17: Dms Range

Page 20: Delivery To Site
Delivery to site Off-loading will only take place at the nearest hard standing to site that is suitable for heavy goods vehicles. If damage is identified on delivery, WPL must be notified within 24 hours. If the nearest road access for a heavy goods vehicle is not adjacent to the site, it is the responsibility of the contractor/purchaser to arrange transport from the road to the site. -
Page 21: Wpl Diamond Plant Location
WPL Diamond plant location The WPL Diamond plant must be sited: • Within 30 metres of heavy vehicle access for de-sludging • As far from the habitable parts of the dwelling as possible. Many local authorities recommend allowing a minimum of 7 metres, but easements are possible for smaller sites subject to local planning approval. -
Page 22: Blower Kiosk
