Background and Objective
The water industry hadidentified the need to develop recognised standards for small pumping stations as a matter of urgency to support the proposed Defra unified standards for new sewers, which is to be based on Sewers for Adoption. The use of packaged pumping stations to a recognised standard could also substantially reduce the cost of upgrading up to an estimated 10,000 existing private pumping stations likely to be transferred to after 2011. However, as there were no recognised standards for these small pumping stations, the use of the existing Sewers for Adoption standard would be likely to lead to over engineering of of the smaller pumping stations with consequent additional costs. The Water UK Standards Board approved the production of a set of Water Industry Specifications.
This project provided a technical secretariat and support to draft a series of Water Industry Specifications for prefabricated pumping stations of diffderent sizes.
Benefits to Participants
- Reduced refubishment costs of small private sewage pumping stations with potential savings of up to £50M to the Water Industry over 25 years.
- Appropriate standards to ensure that new pumping stations transferred from 2011 will be constructed to a suitable standard to allow them to be economically maintained by Sewerage Undertakers after transfer.
