CST WASTEWATER Solutions has supplied an automated septic receival station to Wide Bay Water, replacing an old manual system and improving hygiene and water quality in the process.
Wide Bay Water provides water and wastewater services to the city of Hervey Bay and the townships of Burrum Heads, Howard, Toogoom and River Heads.
According to CST Wastewater Solutions, the new automated septic receival system can process up to ten tanker loads of waste daily. It also provides load measurability to accurately bill to the septic waste producers.
Wide Bay Water says it treats domestic sewage from rural areas as well as waste from business that use greases and fats. The total quantity ranges from 1500 to 12,000L.
Previously, the manual grading process involved the hand removal of any large material from the waste streams. This was obviously not very hygienic. Odour emissions were also a problem, drawing complaints from neighbours.
CST Wastewater Solutions says the septic receival station is designed to allow septic waste tankers to discharge in 20 to 30 minutes. The company also provided number of screw screens for the streams.
The tankers connect to the station using a standard camlock fitting. Before the plant can be operated and the tanker discharged, an access code is required. This allows discharges to be measured and accurately charged to the tanker operator.
According to CST Wastewater Solutions, the wastewater treatment process employs a mechanical first step to screen large solids, grit and greasy floating matter. All material larger than five millimetres is removed and dewatered.
CST Wastewater Solutions says the septic receival station package includes a flowmeter, a control valve, a fully automated controller and a self-contained screen. It is available in different sizes, depending on the application and the required throughput. Flow rates of up to three litres per second are achievable.
