CCTV Pipe Surveys & Condition Assessments
Understanding the condition of existing underground drainage infrastructure is essential for effective maintenance, future development and long-term asset management. CCTV pipe surveys provide a non-invasive method of inspecting wastewater and stormwater pipelines, helping identify potential defects without the need for extensive excavation.
Flow Consulting provides technical support and assessment of CCTV survey findings to identify issues such as cracked or damaged pipes, displaced joints, root intrusion, blockages, sediment build-up and structural deterioration. These assessments help establish the condition of existing drainage systems and identify areas requiring further investigation or remedial work.
CCTV surveys are particularly valuable when assessing infrastructure prior to building alterations, new developments or drainage upgrades. Drawing on over 25 years of practical plumbing and drainage experience, Flow Consulting assists clients in interpreting survey results and developing practical, cost-effective recommendations for maintaining, repairing or upgrading their drainage infrastructure.
Waste Water Treatment Design
Effective wastewater treatment is essential for protecting public health, maintaining environmental standards and ensuring compliance with regulatory requirements. Flow Consulting provides technical assessments of existing and proposed wastewater treatment systems, helping clients identify suitable solutions for residential, commercial and industrial developments.
Our assessments consider the capacity, condition and performance of wastewater treatment infrastructure, including wastewater flows, treatment processes, discharge requirements and potential system limitations. We identify areas requiring improvement, upgrades or alternative treatment solutions to meet operational demands and applicable council requirements.
Flow Consulting works with clients to evaluate wastewater treatment options, address infrastructure challenges and support the planning and design of appropriate treatment solutions. Our focus is on delivering practical, cost-effective recommendations that improve system reliability, support regulatory compliance and provide sustainable long-term wastewater management.
Producer Statements & Compliance
Producer Statements provide Building Consent Authorities with professional assurance that specific aspects of building design or construction meet the requirements of the New Zealand Building Code. Flow Consulting is an approved Producer Statement Author, providing specialist technical assessments and supporting documentation for hydraulic services, plumbing and drainage systems.
Our services include reviewing design documentation, assessing technical compliance and undertaking construction inspections where required. We work alongside architects, engineers, contractors and local councils to identify compliance requirements, address technical issues and provide supporting information throughout the Building Consent and construction process.
Flow Consulting assists clients in meeting their regulatory obligations through clear documentation, practical technical advice and the preparation of Producer Statements within our approved scope of expertise. Our involvement helps streamline the consent and certification process, providing confidence that hydraulic systems have been appropriately designed, assessed and reviewed.
Plumbing, Drainage & Roofing Condition Assessments
Maintaining the integrity of plumbing, drainage and roofing systems is an important part of managing any building or property portfolio. Flow Consulting undertakes comprehensive condition assessments to evaluate the overall state of these essential building services, providing property owners, facility managers and developers with a clearer understanding of their assets and ongoing maintenance requirements.
Our assessments examine the age, condition and functionality of existing installations, considering factors such as material deterioration, system performance, water tightness and compliance with current building standards. We provide detailed condition reports that highlight areas of concern, establish maintenance priorities and assist with budgeting for repairs, replacements and planned refurbishment works.
Flow Consulting combines practical trade knowledge with technical consulting expertise to support informed property management decisions. Whether assessing an individual building, preparing for a property acquisition or developing a long-term maintenance programme, our reporting provides a reliable foundation for managing building assets, extending their service life and planning future investment.
