About CBC Wastewater

CBC Wastewater (Craig Brown Consulting) is based on Waiheke Island in the Hauraki Gulf and a part of the Auckland Region, New Zealand. CBC can be contracted to do design work for domestic onsite wastewater systems in the Auckland Region. Typical work includes:

CBC believes in working with clients to achieve their aims, which includes providing clients with the information they need to make decisions, not choosing a system for them without consultation. CBC charges a set fee that includes everything up to the issuing of consent, so there are no disbursements, additional charges for dealing with council queries or other nasty surprises.

Philosophy

CBC designs water and wastewater systems which best suit the client and the site, rather than specifying a package solution to each situation. With this approach there are a number of areas which require fine judgement and consultation:

  • Installation cost vs operation and maintenance costs
  • Ease of gaining consent vs most desired system
  • Proven technology vs exciting innovations

Fixed Fees
By offering a service with fixed fees, clients that wish to try to gain consent for systems which are less easily consented can feel more free to do so.  Clients, should they wish to, take a risk in terms of possible delays and increased consent processing fees (paid to council) but don’t have to worry about increased fees from their consultant (CBC) and in return CBC takes a risk in terms of additional hours of work and occasionally fees for peer review for complex or unusual designs.

The benefit is the potential to gain consent for systems that are better suited to the environment and client. There is a benefit for CBC in that more interesting work comes in to our office and CBC becomes a consultancy of choice. Where ease of consent is a motivator, CBC is of course happy to help clients take the path of least resistance, but we don’t want to add additional barriers for clients that want to achieve something different, because if you always do what you always did, you’ll always get what you always got.

Praise for CBC Wastewater

Arhaus have worked with Craig Brown on a number of projects regarding water treatment and greywater systems. We value Craig’s passion and independent, un-biased solutions based on what is best for the site and the client’s needs. His reports are extremely thorough, good value for money and Craig takes ownership in dealing with council to make sure information is processed as smoothly as possible.

We recently upgraded the wastewater system on our property at Palm Beach, not a simple process given the steepness and inaccessibility of the site and the array of options available.  Craig Brown’s scoping report investigated all the possibilities and enabled us to choose the right system for the site.  We then commissioned Craig to write the report for Council for building consent and oversee the system’s installation.  We have been impressed by Craig’s thoughtful and thorough approach and his willingness to go the extra mile to help us achieve the best possible outcome for our property.

I commissioned Craig to manage a complex wastewater design and installation project for a studio that I built adjacent to my home, incorporating a composting toilet and above-ground greywater dispersal system. I found Craig to be efficient, easy to deal with and effective in dealing with the local body agencies. He got the systems processed as a variation, saving consent costs, and helped smooth the process of getting the inevitable design changes approved by council. He managed a complex installation project, dealing with multiple suppliers and contractors, locating and selecting the most suitable products at the best prices. He also made life easy for me by explaining the complexities of systems and products where they were confusing, and gave good advice on the best ways to keep costs down. I’m happy with the performance of the system, its appearance, and the environmental outcome.

I have contracted Craig Brown to design waste water treatment plans for my house on two occasions. On both projects I have been impressed by his positive helpful attitude, and his excellent advice on what site layout and materials will give the best and most economical solution for my property. His knowledge of the Auckland City Council and old Auckland Regional Council requirements made gaining necessary consents a lot easier than I had expected. Craig also turned up when he said he would and he met all deadlines. I would not hesitate to recommend him.

This site includes some basic information about different systems that are available. This information is provided for educational purposes, not to be used for decision making or consent applications and no warranty is provided for its accuracy nor completeness. Wastewater system design must consider a number of variables which are site specific and situation specific. We would love to have the opportunity to quote to do your design.

Visitors to this site are encouraged to contribute their own experiences with onsite wastewater systems. We welcome corrections, opinions, experiences, additional information etc.

Lanfax Laboratories
Organisers of the On-Site conference in Australia and source of much information about the content of laundry products (especially useful with regard to greywater reuse).

Country Life Radio Broadcast
Thanks to Marion for sending me this Radio NZ/Country Life radio clip, about a septic tank cleaning business. It has some really good information.

Smarter Homes Website
The Smarter Homes website has a lot of good information about on-site wastewater and greywater.

On-Site Effluent Treatment (OSET) National Testing Programme (NTP)
There is a national testing programme which grew out of initiative by Environment Bay of Plenty, hence some of the earlier data is held on their website, but later detailed data is not available to the public (only to councils funding the scheme). The test certificates however are an easy-to-understand grading system and these are available from the OSET NTP website.
