Sewage Treatment Plant
We offer a full range of packaged sewage treatment plant for domestic and commercial applications. Starting with 1 to 4 population plants for single dwellings all the way up to 375 population plants for hotels, housing estates, schools, offices, restaurants, camping sites and other off mains leisure facilities.
We can size your sewage treatment plant for you based on population, daily flow rates and type of usage. It is important to size your sewage treatment plant correctly in order for it to function most efficiently.
The now ubiquitous sewage treatment plant offers trouble free off mains processing of raw sewage to an environmentally acceptable liquid that can be legally discharged into a water course or soak away system.

The units give quiet, reliable and odour free service with very low running costs. The plants are available with gravity or pumped outlets at various drain invert level options to suit all site conditions.
Once you have decided that a sewage treatment plant is right for you, there are 2 basic options to choose from:
- Traditional 3 stage process. Primary settlement chamber for solids to settle for removal by tanker later, a biozone stage for aerobic treatment of liquid and a final settlement chamber for fine suspended solids. The primary settlement chamber is simply a holding compartment where sewage entering the tank becomes still thus allowing settlement of solids by gravity. The biozone is the where the primary treated liquid is treated by aerobic bacteria that occur naturally in the sewage. The digestion process is accelerated in a sewage treatment plant through oxygenation. Bacteria are given a media on which they can colonize. This media allows bacteria to feed and breathe simultaneously. The media is fixed, rotating or floating. After the biozone the treated liquid enters a final settlement chamber which as the name suggests, simply allows final settlement of solids in suspension by gravity before the treated water leaves the plant.
- Extended aeration process. This system introduces oxygen to the wastewater promoting growth of aerobic bacteria, which destroys organic compounds in the sewage. Incoming sewage enters the aeration chamber where air surging up from a draft tube oxidizes the sewage. This allows an aerobic bacterial colony to establish and digest the organic matter. After an appropriate time period in the aeration chamber the liquid flows into a clarification chamber. The calm conditions in this chamber allow settlement of activated sludge and small organic particles suspended in the liquid. Untreated particles are returned to the aeration chamber for final treatment leaving only purified clean effluent discharging from the system. By continuously recycling sewage via gravity and air lift, almost total digestion of solids is achieved. The advantage of this type of sewage treatment plant is the long (typically 3-5 year) desludge intervals.
