We include sewers and drainage in this category. At P Arter & Son Builders Ltd, we handle all aspects of drainage above and below ground. We can evaluate your project to provide designs for cost effective, easy to use rainwater harvesting systems that are tailored to the project. Commercial, industrial and public buildings with a large roof or surface area possess a natural facility to collect masses of water, and therefore return massive cuts in water bills. Even smaller developments can produce enough water to generate returns on the initial investment. The list below provides a sample of the projects we can assist you with, both above and below ground.
