Design process

This is what usually happens:

1. I am contacted by phone/email by prospective clients and I talk generally about options, possible costs and send out an engagement agreement.
2. Next I will have an onsite meeting with the clients, where I take soil samples, discuss possible types of systems and look at locations for the wastewater system.
3. I prepare a complete design report for submission to the relevant Council for building and/or resource consent and handle any inquiries from the Council relating to this.
4. Once approval has been given, the wastewater system can be installed and the relevant Council will send an officer out to sign off that it has been installed correctly.
5. The type of wastewater system chosen and the size of the disposal field is determined by the number of bedrooms in the house, the soils, the slope of the land, requirements of the local Council and proximity to water sources.
6. The cost of designing a wastewater system is between $2,500 -$ 3,500 and the cost of buying and installing a wastewater system is somewhere in the $14,000 - $25,000 range.
