Hydraulic Design Service

Choosing the right specification of products and ensuring the optimum hydraulic flow is vitally important for a successful drainage project. It's not always easy to get these calculations right - that's why PDS PLC offer a full design service for your drainage system, so you can make use of our expertise as one of the UK's leading drainage specialists.

This hydraulic design service is completely free of charge for the Envirodeck and Hydrodeck bridge drainage systems, the Envirokerb fully recycled, combined kerb drainage system and the Envirochannel linear drainage system.

We can help you avoid common mistakes in choosing the right products for your project. A large number of contracts are designed using ineffective sizes that struggle to drain the required areas due to the velocity of run-off being too low. Conversely designers will sometimes over size the designs to account for unexpected water flows - but this can be counter-productive if it means your drainage system is ineffective at obtaining a self-cleansing velocity. Establishing the correct size of unit enables cost savings over unnecessary large, heavy drainage units.

PDS can help you ensure the contract incorporates the most cost-effective and hydraulically efficient depth-to-width of drainage unit.
