Searching the internet for a good drainage engineering online course and couldn’t find something good at an economical price?

That’s why we developed our drainage engineering course. To understand what is covered inside the course, please read this blog in detail:

The drainage course modules deliver a detailed drainage strategy and design process. where we covered from basic points like where you may get a job as a drainage engineer to an overview of drainage modelling, network modelling, catchment area calculation, a brief outline of Sustainable Drainage Systems, etc.

Module 1 – Component of Drainage Engineering and Drainage Strategy

The first module starts with the key industry for drainage engineers. Here we have informed all the possible options to make a career as a drainage engineer, such as a career as a drainage engineer in consulting firms, construction firms, drainage product suppliers, etc.

We have also covered the key components of Drainage Engineering, Drainage Strategy, Drainage Design, Outfall Design, and Attenuation System Design. In the same module, we have explained what input is needed from the client and other design disciplines to develop the drainage strategy.

The module explains various ways to collate and discharge surface water to the existing drainage system or to the nearby watercourses.

Module 2 – Drainage Design Process

In the second module, we have discussed the drainage design process. Here is the first thing we have explained, how to fix the design criteria and assumption of the drainage design and get an agreement with clients, such as storm period for the worst-case scenario, utilisation of existing drainage system and flow rate to discharge the surface water to the existing system.

After this, we have explained how to calculate Gully spacing and surface water flow width and then we have demonstrated what are best practices for placement of gullies and where not to place the gully pots. After explaining the Gully calculation process, we have explained the career pipe network design. Here we discussed drainage design guidelines, minimum/ maximum gradients, diameters, self-cleansing velocity, etc and finally, some recommended software to run the drainage modelling.

If the longitudinal gradient of the Road is very Flat, then Gully & Pipe design will not provide adequate drainage solutions. In that case, the Kerb drainage system works very well. So we have explained what is the kerb drainage system, it's advantage and limitation etc. We have also discussed other drainage solutions like slot drainage systems, and filter drainage system, their advantage, disadvantage and finally some useful drainage design tips are revealed.

Module 3 – Drainage Outfall Design and Attenuation System

 In the third module, we have drainage outfall options to discharge the road surface water with the help of an underground drainage system. We have discussed the pros and cons of each outfall option. After explaining outfall options, we discussed the drainage attenuation system and explained why the attenuation system is required, its advantage, disadvantages, etc.

We have also explained how to determine the size of the attenuation pond. It is common practice to store surface water within the oversize attenuation pipes and release it with controlled flow rates by using flow control devices. So, we have also discussed flow control devices like Hydrobrakes and how they function.

Module 4 – Drainage Standard Details

In the fourth module, we have discussed drainage standard details of various drainage products such as drainage kerbs, manholes, bus stop drainage kerbs, gullies, slot drains and Hydro-brakes. The drainage standard details course will assist students to understand the granularity of each product and how complex it would be to install these products on-site.

Designing the drainage system in one thing and placing the drainage network, gully pots, manholes, and kerb drainage are the complexity of another level. So, the module will give them an opportunity to visualise the size of those products and learn the best design and construction practices.
