## Summary

The public procurement process titled "Ancillary, Contributing Area and Flow Surveys" is being conducted by Anglian Water Services Limited, focusing on sewer survey services across the entire Anglian Water region in the UK. The tender is currently in the active stage and is set to close on 26 January 2022. The total contract value amounts to approximately £1,249,600, with an initial fixed term of three years and the potential for a five-year extension. The procurement method is selective, involving a negotiated procedure with prior call for competition.

This tender presents significant opportunities for businesses specialising in sewer survey services, particularly those with expertise in ancillary surveys, contributing area surveys, and flow surveys. Companies equipped to provide high-quality surveying, data analysis, and modelling will be well-suited to compete for this contract. Additionally, businesses that can demonstrate technical and economic capabilities as per the selection criteria will have a strong advantage in securing a place among the up to four suppliers awarded the contract for each lot.

## Notice

Anglian Water require the following scope of services across the region. Lot A Ancillary (Manhole and Pumping Station and other surveys as required) Lot B Contributing Area Surveys (CAS) Lot C Flow Surveys The intention is to award between two and four suppliers for each surveying activity/ lot. The proposed contract term is a three year initial fixed term, with the potential to extend for a further five years.

### Lot Information

Ancillary (Manhole and Pumping Station and other surveys as required)

Lot A Ancillary (Manhole and Pumping Station and other surveys as required) Ancillary surveys consist of measuring specific asset parameters such as depth, diameter, pump rate etc. They are typically required when drainage system records are poor or missing. The information is used to update the hydraulic models which are then used for various projects - detailed solution design, investigations, root cause analysis and so on. * Other surveys on occasion are requested. For example, a balancing tank survey or a storage channel survey. These surveys are included in the scope of a Manhole or Pumping Station Surveys, but not always requested or needed and are referenced in the specification)

Options: There is an initial three year term and the contract with the potential to extend for a further five years, or variation on five years, with a no longer than eight year term.

Renewal: The proposed contract term is a three year initial fixed term, with the potential to extend for a further five years.

Contributing Area Surveys (CAS) - Lot B

Contributing Area Surveys are undertaken to understand how networks perform during periods of rainfall and to produce calibrated hydraulic models. They consist of visual observation of where the roof drainage is connected and where necessary undertaking a sound test to establish connectivity. When rainwater enters the foul sewer network it can cause excessive flows in pumping stations and treatment works. This may cause polluted sewage to overflow into streams or possibly within a residential property. The first step in reducing the storm flows within a catchment is to identify where storm water sewers are separate from foul, and those areas which are combined into the one system. The data provided from the survey can enable decisions on making changes to the network with the outcome of reducing stress and possible incidents of sewage overflow /flooding.

Options: There is an initial three year term and the contract with the potential to extend for a further five years, or variation on five years, with a no longer than eight year term.

Renewal: The proposed contract term is a three year initial fixed term, with the potential to extend for a further five years.

Flow Surveys

Flow surveys are needed in order to record actual flow data at critical locations of the sewer system. They consist of installing sensors for measuring and recording the flow depth and velocity in sewers. The information is then used to calibrate and verify the hydraulic models so that the simulated performance matches the observed flows. The verified models support decision making about improvements to the network, efficiencies and cost saving

Options: There is an initial three year term and the contract with the potential to extend for a further five years, or variation on five years, with a no longer than eight year term.

Renewal: The proposed contract term is a three year initial fixed term, with the potential to extend for a further five years.
