CSG Roadshow - Learn to Love Your Septic Tank

Many rural householders forced to rely on septic tanks and cesspits for their domestic sewage disposal are unwittingly damaging their drainage systems and risking costly repair bills.

Fareham-based Cleansing Service Group (CSG), which empties and maintains more than 80,000 septic tanks and cesspits throughout the UK every year, says more and more off-mains drainage systems are not working as well as they should because they’re being used as “rubbish bins.”

The company is taking its campaign to keep Britain’s septic tanks healthy to a number of County Shows during 2011 and at every one experts will be on hand to answer all questions about off-mains drainage and give advice on how to keep septic tanks operating efficiently.

And this means knowing what not to put down them.

CSG say the tanks are a proven and efficient way of treating domestic sewage and need never be a disadvantage for country-dwellers.

“Normal domestic use in which the tank handles drainage from lavatories, baths, sinks and kitchen appliances like dish-washers should pose no real problems, but the systems do need a bit of extra TLC and maintenance,” said CSG’s commercial manager (sewage) Chris Febrey.

“Rural householders who do not enjoy mains drainage will need to remember that septic tanks are living systems which rely on bacteria working within the tank to treat the waste. And that means watching what you put into them.

“Unfortunately we’ve noticed an increasing trend for them to be used as rubbish bins which is creating problems, many caused by increasingly powerful household cleaning products. Many tanks we see are not operating efficiently, are leaking, filling up too quickly, creating smells and getting blocked. They can even pollute local watercourses.”

CSG tanker drivers answering emergency calls to empty systems often arrive to find drain covers lifted out of the lawn by pressure from the overflowing tank and balancing on top of a spreading slick of sewage.

“It’s easy to forget that an average family of three produces about seven cubic metres of sewage in around three weeks. Imagine that over a year and you’ll see just how hard a septic tank has to work or how quickly a cesspit can fill up,” said Mr. Febrey.

He said the company’s Top Five tips for keeping a tank in good order were –

  • Don’t put rags, nappies or sanitary items in the system
  • Don’t pour paints, solvents, pesticides or fats down the drain
  • Use bleaches and disinfectants sparingly
  • Use only boiling water or drain rods to clear blockages
  • Have the tank desludged at least once a year

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
