TP108 Water Collection Guidelines
TP108 Water Collection Guidelines: Essential for Effective Stormwater Management
In the world of construction and environmental management, understanding and adhering to guidelines is crucial. One such important guideline is the TP108 Water Collection Guidelines. This document provides comprehensive instructions on how to manage stormwater runoff effectively, ensuring that our infrastructure is both sustainable and resilient.
What is TP108?
TP108 is a guideline document that specifies how stormwater mitigation should be calculated and managed. Originally developed in Auckland, it has been adopted by various councils across the country. The guidelines are essential for calculating event-based stormwater discharges, designing stormwater drainage facilities, and determining the appropriate size for detention devices.
Why is TP108 Important?
Stormwater management is critical for protecting our streams and other environmental areas from the impacts of stormwater runoff. TP108 provides the necessary calculations to ensure that stormwater is detained and retained appropriately, preventing overcharging of stormwater systems and minimising environmental damage.
Key Features of TP108
- Event-Based Calculations: TP108 includes detailed procedures for calculating stormwater discharges based on specific events, such as 10-year or 100-year rainfall events.
- Designing Drainage Facilities: The guidelines help in designing effective stormwater drainage facilities and treatment detention devices.
- Delineating Flood Inundation Areas: TP108 is also used for identifying flood-prone areas, ensuring that infrastructure is built to withstand potential flooding.
How TP108 Relates to Our Products
At Promax, we understand the importance of adhering to these guidelines. Our stormwater calculators, based on TP108, help in determining the appropriate tank sizes for stormwater detention and retention. This ensures that our products meet the necessary standards and provide effective stormwater management solutions.
If you don't have access to the TP108 guidelines or a civil engineer to assist you, Promax can help. Our team is equipped with the knowledge and tools to ensure that you have the right size tanks for your project.
