We deliver precise topographical, and utility surveys for sewage treatment works, water treatment works and wastewater infrastructure.
Our surveyors combine RICS-regulated expertise with specialist knowledge of operational water and wastewater environments, giving asset managers, engineers and contractors the accurate data they need to plan, design and maintain critical infrastructure with confidence.
Sewage treatment works and wastewater infrastructure are among the most complex operational environments to survey. Accurate, detailed spatial data is essential for every stage, from initial feasibility through design, construction and long-term asset management.
Maintain accurate records of structures, plant, pipework and drainage networks with digital twins and models to support planned maintenance programmes, reducing unplanned operational downtime.
Population growth and regulatory requirements drive ongoing upgrades. Reliable survey data ensures design teams have the spatial context to plan effectively and avoid costly clashes.
Operating within water and wastewater environments carries specific hazards. Accurate site records support safe working, CDM compliance and regulatory reporting obligations.
Whether connecting new developments or extending existing networks, detailed surveys and models of inlet works, treatment streams and outfalls underpin sound engineering decisions.
Surveys adjacent to watercourses or sensitive ecological areas require precise elevation data to assess flood risk, discharge compliance and environmental impact.
Consenting to new treatment infrastructure or operational changes often requires detailed topographic and utility survey data to satisfy planning authority and Environment Agency requirements.


We work with you to understand your project scope, programme, health & safety requirements and the operational constraints of your site.
Full health & safety planning, permit to work compliance and coordination with site operational staff prior to any field activity.
Our experienced surveyors capture all required data using industry-leading instrumentation, working safely within live operational environments.
All field data is rigorously checked and processed to produce accurate, coordinated deliverables in your required format and to the specified datum.
Prompt delivery of drawings, models and data reports, supported by our team’s availability to discuss findings and answer technical queries.
Kemp primarily serves Devon and Cornwall and the wider South West region, where we have an established track record supporting South West Water projects and its supply chain contractors on treatment works across the peninsula.
We also undertake projects further afield for national infrastructure clients, water utilities, and their engineering consultants. Our Redruth and Exeter offices ensure we are well positioned to mobilise quickly across the region.

Surveying within active treatment works requires more than technical capability; it demands operational awareness, robust health & safety systems, and the trust of clients who cannot afford errors on critical infrastructure.
Established Experience
Decades of surveying operational water and wastewater sites mean we understand the constraints and requirements that come with working in these environments.
Regulated & Trusted
As RICS Chartered Surveyors, we operate under a framework of professional conduct, technical rigour, and client accountability that sets us apart.
Utility Sector Track Record
South West Water projects and their principal contractors are amongst our established clients, with surveys completed at treatment works across the region.
Quality Assurance
ISO 9001 registered since 2001. Our quality management processes ensure consistent, auditable standards across every survey deliverable.
Utility Survey Specialists
Via our Seeka Utility Surveys division, we provide PAS 128-compliant underground utility mapping, critical for safe works on treatment sites.
Integrated Service
Topo, utility, building surveys, and setting out, all in-house, on one instruction, with a single point of contact throughout your project.
Most projects will require a topographical survey to record the existing site layout, structures, and levels. Depending on the scope, this may be complemented by a PAS 128 utility survey to locate buried services, a measured building survey for process structures, and 3D laser scanning for complex plant areas. We can advise on the right scope for your specific project requirements.
Yes. We are experienced in surveying within live operational environments, including active treatment processes, confined space proximate areas, and sites with restricted access. We operate under site-specific risk assessments, method statements, and permit-to-work procedures, coordinating closely with your operational team to minimise any impact on site operations.
Survey duration depends on the size and complexity of the site, the scope of services required, and any operational access constraints. A small rural treatment works may require a single day on site, while a major water recycling centre could require several days of field survey followed by further processing time. We will provide a clear programme as part of our quotation.
All our surveys are referenced to Ordnance Survey National Grid (OSGB36) and Ordnance Datum Newlyn (ODN) as standard, unless otherwise specified. Deliverables are typically provided in AutoCAD DWG format and Revit though we can produce data in a wide range of formats to suit your design software and GIS requirements.
Yes. South West Water and the contractors and consultants who form part of their supply chain are established clients of Kemp Engineering. We are familiar with the survey specifications, data standards, and health and safety requirements common to AMP programme works on operational water and wastewater sites.
Yes, through our Seeka Utility Surveys division, we provide PAS 128-compliant underground utility detection and mapping. This is particularly important on treatment works sites where the density of buried process pipework, electrical cables, and drainage presents significant risks to ground works contractors without accurate records.
Survey costs vary with site size, complexity, access requirements, and the scope of services required. We provide competitive, itemised quotations based on a clear brief. Contact us with your project details and we will respond promptly with pricing and a proposed programme.
