Presby Environmental’s new Envirofin Field Day

P1030780 emailSouthern Field Days, Waimumu Feb 2016. L-R Nathan Hoyle, Laser Plumbing Gore; Dick Lamb & Hazel Pearson from Environment Technology and Rhys Harvey from Harvey Tanks. Together they provided the Southern Field Day’s office with an AES (Advanced Enviro-Septic) onsite wastewater treatment system. Designed and installed by Nathan Hoyle, the system is equivalent in size to that for a 3-4 bedroom dwelling. In the soils of Waimumu the AES bed covers only 25m2. Comments Nathan: “AES works in every situation. It’s easy to design & install and with no moving parts, the best thing is we don’t have to keep going back to service them.”

Flushable Wipes?  Yeah Right! Thanks to Ian Gunn and Water NZ for this:

Water NZ Journal No. 188, March 2015, includes an article entitled ‘Problems with Flushable Wipes’. This article referred to the incidence of “serious and costly maintenance issues for wastewater systems” both within sewerage reticulation and treatment plants. Author Nick Walmsley, Technical Manager at Water NZ, says the international experience “suggests NZ water authorities should take a proactive approach to managing the risk before the flushable wipe market is established and significant negative maintenance impacts are experienced”. Nick writes that it is time for “the water utilities, plumbing and drainage industries to band together to lobby against the use of flushable wipes”

Regarding the impacts of flushable wipes on on-site wastewater systems On-Site NewZ has noted a range of comments from a recent email trail going the rounds. For example:

  • Consulting Engineer John Cocks comments that Department of Conservation personnel have reported blockages at DoC facilities from flushable wipes.
  • Andrew Dakers of ecoEng notes that on-site wastewater servicing colleagues have found flushable wipes a major problem in septic tanks and home treatment plants. Andrew strongly advises homeowners to avoid flushing such wipes into their on-site wastewater system.
  • Oasis Clearwater states that their servicing agents are finding these wipes do not break down, and are having to pull them out of treatment units during service. Oasis Servicing Manager Tina Nyberg says they highly recommend to customers not to use them.
  • Consultant Malcolm Linton has had a wastewater pump burnout caused by wipes wrapping around the pump.

On-Site NewZ has checked out one brand of flushable wipes from a local supermarket, and noted the following statements on its packaging:

Description:
The term “Biodergradable” is used on the packaging as one of five descriptors.

Instructions:
Open the resealable sticker and dispense one wipe at a time – take care our PRECIOUS Flushable Wipes are more fragile than baby wipes because they are designed to break up in the sewage system

Warning:
Flush one wipe at a time, use a full flush. These wipes are not designed for macerator toilets or use in septic tanks.
This product is specifically not for use in on-site wastewater systems, but the problem is, how many householders are really going to read the fine print and act accordingly? The fact that the company involved is not able to spell “biodegradable” properly raises a question re the integrity of the overall claims made for the product.

So, a quick response to the use of flushable wipes: DO NOT FLUSH – DISCARD WIPES WITH HOUSEHOLD REFUSE

The following is interesting because it outlines the importance of onsite wastewater treatment systems which recharge aquifers and which are gaining in popularity worldwide.as water resources become increasingly important.

“NOWRA Past President Tom Fritts testified on NOWRA’s behalf before Congress March 18. He spoke in support of greater funding and more Environment Protection Agency staff support for the onsite industry. His testimony was before a subcommittee of the House Appropriations Committee which determines EPA’s budget.
