Sewerage
This is a system of sewer pipes (sewers) collecting sewage and taking it for treatment or disposal as required.
Jance provides sewerage and drainage services ncluding: construction and rehabilitation of sewer lines, storm drainage, oil waste disposal and septic tanks.
Drainage
Our civil engineers are responsible for drainage in construction projects. They set out from the plans all the roads, street gutters, drainage, culverts and sewers involved in construction operations.
Drainage options include point drainage (which intercepts water at gullies or points) and channnel drainage (which intercepts water along the entire run of the channel).
