Planning is the key to a successful drainage system

Drainage is a critical part of every construction project, both large and small, with this infrastructure providing the vital arteries through which rainwater and wastewater can drain away from a building quickly and safely. An effective system is crucial to eliminate the risk of flooding and health issues that can present significant risk to people and property.

However, all too often the specification of drainage systems, especially at the design stage, is either overlooked altogether or carried out as an afterthought. For example, flow rate calculations are frequently incorrect, leading to over or under specification of drainage; similarly, poor planning results in compromises during the construction phase, with projects that could easily have been completed using standard drainage units requiring custom engineered solutions.

Each building has its own unique set of drainage needs and it is these critical factors that must be considered when planning drainage systems. Indeed, whether you’re involved in designing or building a new project or upgrading an existing building, every aspect of the system must be carefully planned to meet the correct drainage requirements simply, quickly and within budget.

Jill Jones, Director at Environmental Consultants Peak Associates, noted “specifying drainage systems correctly at early design stage can keep costs to a minimum, while boosting functionality and long-term reliability.”

“Too often these issues are left until too late, even after construction has begun, which can lead to complex re-designs and modifications, even forcing the use of pumped systems that may not have been needed. This just increases long-term maintenance costs and the risk of future problems, as well as increasing the costs of installing the system.”

In essence, the overall drainage system needs to deal with the removal of two types of water: foul water from waste, bathrooms, kitchens or utility rooms; and surface water from rainfall. Thanks to the introduction of innovative drainage technologies and the level of technical support available from leading manufacturers, the task of creating an effective drainage system can now be carried out in a quick, accurate and straightforward manner, avoiding delays, wasted time and poor performance.

In particular, the latest generation of market leading drainage system components are manufactured from high performance materials that make them resistant to corrosion, while the experience and customer support offered by the leading specialists in the industry eliminate design risk. Most recently we have seen the introduction of innovative modular drainage systems that have been developed to help cut build times and costs, enabling quick and easy design and installation in almost any building.

Jill continued “having a suitable system to deal with surface water is now a required part of the planning process and the designs must incorporate a suitable SUDS (Sustainable Urban Drainage System) design to reduce flood risk. Using modular units or incorporating this into early design can help this be done cheaply and actually add to the aesthetics of the final design.”

When designing a drainage system for particularly specialist or demanding applications where corrosion free materials and aesthetic considerations are crucial, including chemical plant rooms, food and drink processing factories, washdown areas and highly specialised architectural projects, the use of other high performance materials might be necessary.
