7. Maintain External Drainage Systems
Blocked external drains can be just as disruptive as internal drainage failures.
Gullies, channels, gutters, and surface water drains are constantly exposed to leaves, litter, moss, mud, and environmental debris. Without regular maintenance, these systems can quickly become overwhelmed, particularly during periods of heavy rainfall.
Flooding around entrances, car parks, loading bays, and service yards can create serious operational and safety concerns.
Businesses should ensure that external drainage systems are inspected routinely and cleared when necessary.
Properties surrounded by trees require particularly vigilant maintenance during autumn and winter.
Surface water drainage is especially important for warehouses, industrial estates, hospitality venues, and retail premises where customer access and vehicle movement are essential.
