You won’t! Not unless the sewer is actually overflowing or the sinks and shower are draining very slowly. Not until the situation becomes very bad, does the householder consider major cleaning or replacement. By this time the problem has reached a point where something must be done urgently. However – with a little preventative maintenance, you will be able to foresee a lot of the serious problems that might arise.
It is understood that standing water in and around facilities can cause severe structural damage. Potential problems include cracked foundations due to static water pressure buildup on the wall, settling, degradation of adjoining building materials, and freeze–thaw issues. Similarly, ponding (i.e. water collection) and hydroplaning on roads, highways, and bridges are possible safety hazards that can be avoided.
Effectively handling and transporting away rainfall during and after storms is a prime component in facility and road construction planning.
Surface drainage can be accomplished using three different systems – in-line pits, open swales, or grated trench drains. Cost comparisons have shown modular trench drains to have lower total installed costs when labour, excavation, pipework, grading etc., are taken into account.
