Wastewater Design

Practical Wastewater Solutions, Designed for Your Site

B M Designs provides specialist wastewater and OSET design services for residential, rural, commercial and community projects across New Zealand. We develop practical, site-specific wastewater solutions designed around your property’s conditions, project requirements and long-term needs.

From initial site evaluation and wastewater assessment through to detailed design, documentation and consent support, we provide clear technical guidance throughout the process.

Comprehensive Design Support From Assessment to Consent

We provide a complete range of wastewater and OSET design services to help move your project from initial assessment through to an appropriate, documented solution.

01 // Site Evaluation

We assess your property and relevant site conditions to understand the factors that may influence wastewater design. This includes reviewing the site, proposed development, wastewater requirements and potential constraints.

02 // OSET Reports

We prepare OSET documentation to support onsite wastewater system design and project requirements. Our reports provide clear technical information to help establish an appropriate wastewater solution for the property.

03 // Schedule 5

We provide Schedule 5 documentation as part of the wastewater design and assessment process where required for your project.

04 // CAD Site Plans & Details

Our wastewater designs include detailed CAD site plans and supporting details to clearly communicate the proposed system, layout and relevant site information.

05 // Wastewater Disposal Design

We develop wastewater disposal designs and options based on the characteristics and requirements of your site. Solutions are considered around available space, site conditions, proposed use and practical installation requirements.

06 // New Wastewater System Design

For new residential, rural and commercial developments, we design wastewater systems to suit the intended use of the property and the specific conditions of the site.

07 // Existing System Assessment

We can assess existing wastewater systems to identify potential issues, limitations or areas requiring improvement. Where appropriate, we can help determine practical options for addressing existing system requirements.

08 // Remedial Solutions

Where an existing wastewater system requires improvement or replacement, we can assess the situation and develop practical remedial solutions suited to the property and project requirements.

09 // Building & Resource Consent Support

We provide wastewater design documentation and support throughout the building and resource consent process, helping ensure the required information is clearly prepared and presented.

A Clear Process From Site Assessment to Final Design

We keep the process straightforward, providing practical guidance from the initial assessment through to design and project support.
