WPL Diamond DMS

Sewage treatment plant for 
1 - 20 people

The WPL Diamond range offers sewage treatment plants for properties that are not connected to mains drainage.  The DMS range includes a range of sizes suitable for 1-20 people.

Why Diamond?

There are several key reasons to choose a Diamond wastewater solution for your development:

• Minimal maintenance, low running cost - unlike other sewage treatment plants on the market, the Diamond’s unique design has no internal moving parts.  This means that it requires minimal annual maintenance, making it economical to run.
• Kind to the environment – the Diamond’s treatment process requires no chemicals, so it’s kind to the environment.
• Minimal visual impact – the Diamond’s tank is buried entirely underground, so it has minimal visual impact.
• No smells – most other treatment plants have primary tanks which store settled solids and can emit odours.  The Diamond has no primary tank and is therefore odour-free.
• Long emptying cycle – the Diamond’s continuous bacterial digestion treats wastewater to a standard that meets all normal Environment Agency consents.  This treatment process can achieve a de-sludge (emptying) period of up to three years – much longer than that of most other plants.
  

Process Performance Guaranteed

The Diamond treats wastewater to a 95 percentile standard of:

• 20mg/l Biological Oxygen Demand (BOD)
• 30mg/l Suspended Solids (SS)
• 20mg/l Ammoniacal Nitrogen (AMM-N)

If more stringent environmental requirements are specified, please contact WPL on 02392 242 600

How does the Diamond treatment plant work?

• Wastewater enters the Diamond via the inlet pipe directly into the central aeration chamber (1)
• The central aeration chamber (1) empties into the bottom of the outer clarifier chamber (2).
• A drop pipe (7) releases air through a disc plate diffuser (4).
• An upward flow of process fluid draws settled solids (5) through the draft tube (3) to discharge at the surface of the aeration chamber.
• The design of the draft tube (3) ensures complete mixing of oxygen with the sewage. Oxygenation allows aerobic organisms, that biologically degrade wastewater contaminants, to grow.
• Gravity causes aerated solids to settle at the tank bottom (5) where they are drawn back up through the draft tube (3).
• Raw sewage displaces biological solids (8)from the aeration chamber (1) to the clarifier chamber (2). Quiescent conditions in the clarifier allow digested solids to settle at the base (5) and  return to the aeration chamber (1).
• The clarified effluent flows up through the scum baffle (9) and over the weir arrangement (6) prior to discharge via the outlet pipe.

Soakaway's



A vital part of any septic tank is its soakaway or drainage field, without this a septic tank may not be the correct option. (Sewage treatment plant or a cesspool)
Building Regulation state, soakaways should be sited so as not to have an adverse effect on the sub structure of any buildings

Apart from the Building Regulations there are various good practices regarding the positioning of a soakaway;

•    Avoid sitting within 5 metres of a road or highway.
•    Avoid sitting within 2.5 metres of a boundary.
•    Note that areas with a high water table are likely to be unsuitable.
•    Any new soakaway should not compromise existing systems.

Permeable sub-soils such as sand, along with permeable bedrock types, such as limestone, sandstone or chalk, are usually good areas to have a soakaways.
Whereas hard, igneous rocks, such as granites and basalts, and heavy soils such as clay may mean a soakaway is not going to be feasible.
There are many different type of soakaways available for septic tanks, the most common being a herringbone system.
Septic Tank Supplies are able to supply both 110mm sewage pipe and 110mm perforated pipe used in the installation of soakaways.

Design and Construction of your Soakaway
Soakaways should be always constructed with perforated pipe, and laid in trenches with the same gradient not steeper than 1:200
Pipes should be laid on a 300mm layer of shingle or medium of up to 50mm.
The trenches must be filled 50mm above perforated pipe and covered with a membrane and then filled in with soil.
The trenches for a soakaway should be between 300mm and 900mm wide with a distance of 2m between trenches.
It is recommended that an inspection chamber should be installed between the septic tank and the soakaway. (this is to make sure no solids are coming out through the outlet pipe into your soakaway)

Other Factors
Drainage fields are not to be constructed under driveways, parking areas, buildings, neartrees, dwellings, boundaries, watercourses & boreholes.
