| Event | Description |
|---|---|
| Introduction of computer modeling technology | In the early 1980s, computer modeling technology was introduced, revolutionizing the way sewer systems were analyzed and designed. |
| WASSP (Wallingford Storm Sewer Package) | The first computer modeling package specifically designed for use in the UK, WASSP, was launched in 1981. Based on the Wallingford Procedure, WASSP allowed for the simulation of rainfall, runoff, and pipe flow in order to design and optimize sewer systems. |
| Initial version of WASSP | The initial version of WASSP was not user-friendly and required a mainframe computer to run. |
| Development of WASSP | As computers became more advanced and user-friendly interfaces became more in demand, WASSP was further developed to become more accessible. |
| Impact of computer modeling on sewer design | The use of computer modeling in sewer design not only made the process more efficient, but also encouraged a deeper understanding of how sewer systems actually functioned. |
| Philosophy of cost savings through high-tech analysis | The belief that sophisticated problem analysis could lead to significant cost savings in construction became widely accepted, and this philosophy was outlined in the Sewerage Rehabilitation Manual published by the Water Research Centre. |
