‘Potholing’ for Utilities Saves Time and Money
Damaging existing utilities can be costly in terms of project downtime and potential contractor fines. Potholing was developed to safely and economically uncovering utilities
The low-pressure water and air will not damage existing utilities like a backhoe, compact excavator or shovel. In fact, the air and water move around the existing utilities, giving the operator a clear view.
While locators are becoming more accurate, it's still important to see exactly where the line or pipe is located. Regulations require services to be identified before the use of machinery around these services. Usually contractors will dig by hand to visually locate the cables or pipes. A safer and more effective alternative is available by using a non-destructive method like vacuum excavators.
Using a vacuum excavator instead of a shovel has advantages. A shovel against a water pipe is non-destructive, but on a fiber optic line a shovel can be as destructive as a backhoe, especially in hard ground conditions.
When cable has been installed using horizontal directional drills (HDD) rather than trenchers, so you don't have the old-fashioned ditch line to warn the person tasked with finding the cable that the cable is near.
Thrust Boring Soil Displacement (Moling)
Benefits of Thrust Boring
Pipes that are placed down by Thrust Boring can be used for gas, water, telecommunication wires, sewage etc. Thrust Boring enables the pipes to be laid down more easily and with so much more accuracy.
Less expensive than traditional trenching methods.
Minimal excavation other than the necessary connection points
We pride ourselves in minimal disruption to our customers and their property, compared with traditional methods.
Moling is suitable for almost all types of soil conditions.
Biolytics Septic Tank Waste Water Treatment System
Biolytix works with nature, doesn't fight it...so you save
12 Reasons to buy a Biolytics System
The ecosystem in a tank treats the waste: no expensive aerators to run, fix and replace
Cuts electricity use by around 90%: reducing carbon dioxide emissions by about 1 tonne per annum
No routine pump-outs: save sludge transport and disposal costs
Only one annual check-up: most others need 3 - 4 services each year
The only treatment system approved to treat household food waste
No need to space showers and washing: adapts to your family needs
You can't hear it: no droning aerators up to 12 hours every day
Odourless: no septic stage; no smell from vent pipes
Negligible methane emitted: septics emit large amounts, 21 times as potent as carbon dioxide
Chemical-free system: no chlorine continually disposed of in your garden
The most compact system: less to transport; less disruption to the garden
Safe and waterwise irrigation: doesn't waste water or potentially spray pathogens around
Rx Plastics Airtech Systems
RX Plastics manufactures product to assist in the disposal of effluent from two main sources.
Domestic sewage treatment - Airtech aerated septic tank systems and the standard Septic tank systems. Our lightweight aerated wastewater treatment plants are designed to process and recycle all domestic sewage and wastewater effectively. RX septic tanks provide a simple, practical and efficient on-site alternative for managing household sewage disposal.
Aerated Wastewater Treatment System
The AirTech™ 9000 system is an efficient, lightweight sewage treatment plant that safely and effectively processes all household sewage and wastewater and recycles it as clear, odourless nutrient enriched water to irrigate landscape, shelterbelt, coppice wood lots or existing planted areas.For the environmentally minded this means that the sewage and wastewater is treated on the property where it is produced and then recycled for reuse with little or no environmental impact on the land.
The AirTech™ 9000 Aerated Wastewater Treatment System (AWTS) is New Zealand's most innovative sewage treatment system specifically designed to maximise the treatment of all household sewage and wastewater.Before we bring any product to the market, we throughly explore and test all aspects of the design and function to ensure that by the time it reaches you, we know it will perform to our usual exacting standards.
The AirTech™ 9000 system's innovative design is the result of over 4 years commitment to developing the best sewage and wastewater treatment system available today.Our goal was to make a simple, lightweight, polyethylene system and at the same time avoid the failings of existing plastic tank systems that have been tried with varying degrees of success in the past.
Designed recognising the latest industry standards and incorporating many innovative features we believe the AirTech™ 9000 is unequalled by any existing polyethylene tank system available today.
Waterotor Irrigation Valves
Designed to control the flow of water to sprinkler lines without the use of solenoid valves, the Waterotor comes in four and six outlet models. Six outlet models can serve as three outlet valves and four outlet models as two outlet
Both the water inlets and outlets, which we refer to as ports, are threaded to receive 20mm plastic fittings
The entire flow of water from the inlet line is switched to each of the outlet lines in a continuous sequential manner without electrical or mechanical control.
Water flowing through the Waterotor turns an impellor, which through gearing opens internal valves to deliver an equal amount of water to each outlet.
Water supply can also be from a suitable pump, in which case the flow to the Waterotor is controlled by turning the pump on and off.
Any water suitable for plant growth can be passed through the Waterotor, which is corrosion resistant. The water however must be free from solid contaminents which can lodge in the internal mechanism and cause malfunction, as with any irrigation control valve.
There is a minimum water flow requirement of about 18 litres per minute passing through the Waterotor to ensure trouble free operation. If the speed of the flow is too slow the impellor stops turning and the valve will not change from port to port.
