To determine which system best suits the customer's needs BioHarmony Inc. offers services related to consultation, research of the property, regulations, legislation and zoning, Aerated Wastewater Treatment System design and installation for the following Sewerage Treatment systems:
British Columbia
1. Type 1 (traditional) Septic Systems
2. Type 2 (Aerated Wastewater Treatment Systems)
3. Type 3 (Aerated Wastewater Treatment Systems)
4. Sewerage Dispersal fields (Septic Drain fields)
Gone are the days where you simply drew a design on a paper napkin in a coffee shop and submitted it to your local Health Authority or Government agency. Depending on Provincial regulatory requirements a number of items need to be addressed before a design can be identified and submitted on your behalf.
1. A meeting with you the owner/developer to determine what it is that you want to do with the property.
a. What is your vision for the property both from a building as well as landscaping perspectives?
b. What is the frequency usage, is it full time use or is it a cottage which has extremely high usage in the summer months and very little to non usage in the winter months or off season months?
c. Other items that may have a bearing on the design or use of the system.
2. Daily Design Flow (DDF): - This is a calculation based on occupancy either by number of people or by the number of bedrooms and the square footage of the facility being serviced and is normally based on regulatory requirements.
3. Technical Site Assessment: - This is where either a Registered Onsite Wastewater Practitioner (ROWP), Qualified Professional Engineer or a person qualified in soil analysis and sewage treatment attend your site and use a variety of methods to determine how capable the soil is of moving treated effluent through the soil for long term effluent dispersal.
4. Within the proposed dispersal site, methods may include one or more of the following and be dependent on the experience of your ROWP or Engineer:
a. soil pits to view the different soil horizons,
b. soil samples obtained for laboratory analysis,
c. percolation tests and or
d. permeameter tests.
5. What is the local area parameters (some things considered are as follows):
a. Topography - drainage issues or bedrock or clay issues,
b. Temperature in both the summer and winter months,
c. Rain fall in the summer months and rain/snow fall in the winter months,
d. The type of vegetation that currently grows in the area,
e. How is the site to be serviced with respect to drinking water and other services.
f. What is the long term community plan for the area?
g. Other items as identified by the your design person.
As you can see there is a process to follow that will enable you the owner to move forward with your project. The more information that you are able to provide us, the designer, the easier it is to gather the information and present you what options you have for the site.
