A variety of maintenance activities were completed across One Alliance locations during the contract period, covering wastewater treatment assets, sewer networks, pumping infrastructure and supporting operational facilities. Vacuum tanker services, sewer maintenance works, rehabilitation activities andrelining projects formed part of the wider maintenance programme.

Operational teams worked across multiple sites throughout the year, responding to servicing requirements as they arose and carrying out maintenance activities alongside ongoing site operations.

Many of these activities took place within active environments where vehicle movements, site access, operational processes and infrastructure maintenance continued throughout the contract period.



Managing Wastewater Assets Across the Network

One Alliance maintains a range of wastewater infrastructure assets across its operational network. Treatment facilities, sewer systems, pumping assets and associated infrastructure all required planned maintenance activities throughout the year.

Maintenance requirements varied between locations. Infrastructure condition, asset type, servicing schedules and operational priorities influenced the work carried out at each site.

Operational teams attended locations throughout the contract period to complete inspections, cleaning activities, maintenance works and wastewater treatment support services.

Some sites focused on treatment processes and pumping infrastructure, while others required maintenance activities across sewer networks and supporting drainage assets. Servicing schedules were reviewed throughout the year according to operational requirements and asset condition.

Maintenance requirements changed throughout the year as infrastructure condition, operational demands and servicing priorities evolved across different locations. Some sites required additional inspections and cleaning activities, while others continued under planned maintenance schedules established earlier in the contract period.



Preparing Sites for Planned Maintenance Activities

Preparations began before maintenance activities commenced at individual locations. Site assessments were completed to review wastewater assets, sewer infrastructure, access arrangements and servicing requirements.

Planning discussions focused on how maintenance activities would be carried out at operational sites. Vehicle access routes, equipment requirements, servicing frequencies and infrastructure condition were reviewed during this stage.

Site representatives, contractors and operational personnel worked through maintenance arrangements before activities commenced. Servicing schedules were organised around site requirements and operational activities.

Maintenance priorities differed between locations. Some sites required wastewater treatment support and tanker services, while others focused on sewer maintenance, rehabilitation works or relining activities.

Access arrangements varied between locations and were reviewed before servicing activities commenced. Vehicle movements, site traffic, operational processes and infrastructure layouts all influenced how maintenance works were carried out.

Reviewing Infrastructure Condition and Access Requirements

Different sites generated different maintenance requirements. Treatment facilities, pumping assets, sewer networks and operational compounds all required individual assessment before servicing activities commenced.

Site visits provided an opportunity to review infrastructure layouts, access restrictions, maintenance requirements and operational considerations before work began.

Asset reviews were completed throughout the network to identify locations requiring additional maintenance, rehabilitation works or repair activities.

Information gathered during site assessments supported maintenance planning and assisted with the coordination of servicing activities across multiple locations.

Specialist Resources Used Throughout the Contract

The maintenance programme involved a combination of vacuum tankers, jetting units, CCTV inspection systems, rehabilitation equipment, relining systems and specialist waste transport assets.

Operational teams worked across multiple locations carrying out inspections, cleaning activities, waste removal operations, maintenance works and infrastructure repairs.

Equipment requirements varied according to the activity being completed. Wastewater treatment support activities relied on tanker operations and waste transport assets, while rehabilitation and relining works required specialist repair equipment.

Personnel were assigned according to site requirements and the nature of the work being carried out.

Wastewater Treatment Activities Across Operational Locations

Wastewater treatment services formed part of the wider maintenance programme delivered throughout the contract period.

Operational teams attended treatment facilities to support servicing activities, infrastructure maintenance, inspections and waste management operations. These activities were completed across multiple locations according to site requirements.

Maintenance works provided opportunities to review asset condition and identify locations requiring additional servicing or repair activities.

Treatment assets required ongoing inspection throughout the maintenance period. Operational teams reviewed infrastructure condition during site visits while carrying out cleaning activities, waste removal operations and routine maintenance works.

Different treatment facilities presented different servicing requirements. Some locations required additional cleaning activities, while others focused on inspections, waste management operations orinfrastructure maintenance.

Tanker Support and Waste Removal Activities

Vacuum tanker services were used throughout the maintenance programme to support waste removal activities across operational sites.

Tanker units attended locations requiring sludge removal, liquid waste extraction, cleaning activities and infrastructure servicing. Collected materials were removed from site and transferred through established disposal arrangements.

Waste removal activities were coordinated alongside maintenance works to support servicing requirements across the network.

Waste removal requirements varied according to infrastructure type, servicing schedules and site conditions. Vacuum tanker units were used to remove liquid waste, sludge and accumulated materials identified during servicing activities.

Tanker support activities were completed across a range of operational environments throughout the maintenance period. Infrastructure type, waste volumes and servicing requirements all influenced how waste removal activities were scheduled and carried out at individual locations.




Maintaining Sewer Infrastructure Across the Network

Sewer maintenance activities were completed across multiple locations throughout the contract period.

Maintenance works included inspections, cleaning activities, blockage removal operations and infrastructure assessments carried out across sewer networks and associated assets.

Operational teams attended locations requiring routine maintenance as well as sites where additional servicing activities had been identified during inspections.

Maintenance requirements varied according to infrastructure condition and operational demands present at each location.

Sewer infrastructure was inspected throughout the contract period to identify locations requiring additional maintenance activities. Cleaning operations were carried out where accumulated materials, sediment or debris had been identified within the network.

CCTV Surveys and Cleaning Operations

Inspection and cleaning activities were carried out throughout the maintenance period to review sewer condition and remove accumulated materials from infrastructure assets.

CCTV surveys formed part of the inspection process carried out across the sewer network. Operational teams reviewed underground assets, recorded infrastructure condition and documented any defects or restrictions identified during inspections.

Cleaning works removed accumulated materials from the system, with survey records contributing to future maintenance and repair activities where required.

Infrastructure Rehabilitation Activities

Sewer rehabilitation activities were completed where infrastructure condition required additional repair or restoration works.

Rehabilitation projects focused on restoring sections of sewer network identified during inspection and maintenance activities.

Repair activities varied across the network depending on infrastructure condition and the findings recorded during inspections. Some locations required localised repairs, while others formed part of wider rehabilitation activities completed during the maintenance period.

Maintenance requirements were assessed at individual sites before repair activities were scheduled and carried out.

Repair solutions varied according to infrastructure condition and operational requirements present at each location. Maintenance personnel reviewed available options before rehabilitation activities commenced.

Works were coordinated around site operations to allow repair activities to be completed while maintaining access where required.



Relining Works Within Existing Sewer Assets

Sewer relining activities were completed at locations where repair works could be carried out without extensive excavation.

Relining systems were installed within existing infrastructure to restore operational condition while reducing disruption to surrounding site activities.

Maintenance personnel completed relining works according to site requirements and infrastructure condition identified during inspections.

Relining activities formed part of the wider rehabilitation programme delivered throughout the contract period.



Coordinated Maintenance Across One Alliance Assets

The contract involved wastewater treatment services, vacuum tanker operations, sewer maintenance activities, sewer rehabilitation works and sewer relining projects delivered across multiple operational locations.

Maintenance schedules, inspection programmes, waste removal operations and repair works were coordinated throughout the contract period according to site requirements and servicing priorities.
