Construction of Sewerage Systems

Sewers are among the infrastructure that is quite challenging and expensive to construct. If sewers are not correctly laid down, they may end up with remedial works which are costly and also time-consuming. Remedial works are also disruptive as they also have negative effects on the reputation of the organization.

If keen attention is paid, some errors might be avoided. It’s crucial that contractors consider all the laid out plans, requirements and specifications before they start the actual construction. An on-site guide should be available so as to guide the contractors when laying down the sewer lines. Additionally, they must have manuals with all the common errors that they should attempt to avoid at all cost.

There are different sewerage designs that can guide contractors when undertaking the assignment. Sewer contractors must be up to date with all the latest sewerage designs and technology.

They should make sure that all works are completed and have reached the required standards.

When making trenches and excavations, all boulders and tree stamps should be efficiently removed. All watery, muddy and soft grounds in the trench should be removed. All wastes should be dumped well so that they don’t roll back into the trench. Equipment’s and materials used in the excavations should be kept safe and well operated at a safe working distance.

Contractors should oversee that the trench doesn’t have external items like logs and rocks. They should also be safeguarded from site traffic, slips, falls and trips. Working staff should also be warned when accessing areas that trenches have been dug so that they don’t end up falling and hurting themselves. Trenches should not be waterlogged. The base of the trenches should be firm. Also, they should not be dug wider than it’s required. Wider trenches will mean that the pipe will carry too much load which is heavily avoided. If the ground conditions don’t favour laying of pipes and manhole construction doesn’t apply, an engineer will be asked to formulate a solution.

Great care must be taken so that debris doesn’t make the construction of the sewer unmanageable. Slit and sludge should be well disposed of so that they don’t flow back into the trench. Sludge and slit mainly cause blockages, restrictions, pollution, flooding and also make it challenging to treat wastewater. They make the operations slow and times become costly.

Sewerage construction must comply with all the diversion works and drawings. A similar obedience is required when it comes to public sewer connections. All works must adhere to all the details that have been extended by the local authority. Contractors should comply with the drawings provided by building control Authority so as to avoid any mix-ups and remedial works. There should be no errors or deviations made from the specifications laid out. All pipes and materials used in the construction must be standard and fully agreed by water ministry. Before the works commence, the contractor should be awarded a certification approving the standards of the materials to be used.
