🎯 Role Definition

A Water Consultant provides technical leadership and practical delivery across water resources, hydrology, hydrogeology, water quality, stormwater and wastewater projects. This role designs and implements assessment programs, develops and calibrates hydrologic and hydraulic models, prepares permit applications and EIAs, advises clients on regulatory compliance, and translates complex water science into practical, cost‑effective engineering solutions. The ideal candidate blends field experience, data analysis, GIS and modeling proficiency (HEC‑RAS, SWMM, MODFLOW, SWAT), excellent technical writing, and client/stakeholder engagement skills.

Core Responsibilities

Primary Functions

  • Lead and execute water resources assessments including water balance studies, surface water and groundwater investigations, long‑term monitoring plans, and integrated catchment assessments to inform sustainable water management and infrastructure design.
  • Develop, configure, calibrate and validate hydrologic and hydraulic models (for example HEC‑RAS, HEC‑HMS, SWMM, SWAT, MIKE, MODFLOW) to simulate flood risk, stormwater conveyance, river hydraulics and groundwater flow for design and regulatory submissions.
  • Design and manage field investigations and sampling programs — including borehole logging, aquifer tests, surface water sampling, continuous monitoring (level, flow, conductivity), and chain‑of‑custody coordination with accredited laboratories — to generate defensible datasets for analysis and reporting.
  • Prepare technically rigorous, peer‑review quality reports, feasibility studies, technical memoranda, and environmental impact assessments (EIA) that clearly state methods, assumptions, results, uncertainty and recommendations for clients and regulators.
  • Advise clients on regulatory and permitting requirements (water abstraction, discharge consents, wetland permits, floodplain development permits) and prepare permit applications, supporting documentation and responses to agency technical comments.
  • Perform flood risk and climate resilience assessments, including floodplain mapping, depth‑damage analysis, climate change scenario testing and development of adaptation and mitigation measures to reduce risk to people and assets.
  • Design stormwater management and sustainable drainage systems (SuDS) including detention/retention basins, green infrastructure, infiltration systems and low impact development (LID) measures, integrating hydraulic design, water quality treatment and maintenance considerations.
  • Conduct groundwater resource evaluations including conceptual site models, contaminant transport assessments, groundwater vulnerability mapping, and recommendations for monitoring or remediation where required.
  • Provide wastewater and effluent treatment advice, perform loadings calculations, assess receiving water impacts, and design or review treatment process alternatives for compliance with discharge standards.
  • Deliver cost estimates, scope of works, technical schedules and risk registers for water projects; manage project budgets, contractor scopes and quality control to ensure on‑time, on‑budget delivery.
  • Lead data management, QA/QC and analysis workflows for hydrometric, water quality and groundwater datasets; apply statistical and time‑series analysis, trend detection, and uncertainty quantification using Python, R, MATLAB or Excel.
  • Produce GIS deliverables including spatial analysis, watershed delineation, floodplain mapping, and stakeholder maps using ArcGIS or QGIS to support planning, permitting and community consultation.
  • Provide technical oversight and mentoring to junior staff and field crews, develop training materials, review deliverables and ensure consistent application of modelling and field methods.
  • Engage and coordinate with multidisciplinary teams — ecologists, engineers, planners and community stakeholders — to integrate water solutions into broader environmental and development projects.
  • Conduct peer reviews of modelling studies, technical reports and designs to validate assumptions, methods and regulatory compliance, and to identify opportunities for optimization or cost savings.
  • Support tender preparation and pursue business development opportunities by drafting technical proposals, writing capability statements, and presenting technical approaches to prospective clients.
  • Communicate complex technical concepts and project findings to non‑technical stakeholders and decision‑makers through presentations, workshops, public consultations and clear executive summaries.
  • Implement Health, Safety and Environmental (HSE) protocols and site access plans for fieldwork, including risk assessments, permit to work, and contractor safety briefings.
  • Monitor policy, regulation and best practice developments in water management, climate adaptation and environmental protection to ensure advice and designs remain current and compliant.
  • Integrate nature‑based solutions and green infrastructure where feasible, preparing conceptual designs and cost‑benefit analyses that balance ecological, social and engineering objectives.
  • Support litigation and dispute resolution with expert witness statements, technical appendices and oral testimony related to water resource impacts, flood risk or permitting matters.
  • Coordinate laboratory analyses, validate lab QA/QC reports, and interpret chemical, biological and toxicity data to provide water quality assessments and remediation recommendations.
  • Oversee procurement and management of subcontractors and specialty consultants (drillers, modelers, labs), ensuring scopes, schedules and deliverables meet project requirements and quality standards.

Secondary Functions

  • Support ad‑hoc data requests, dashboarding and exploratory data analysis for clients and internal teams using Python, R, SQL and visualization tools (Power BI, Tableau).
  • Contribute to the water team’s technical strategy, methodology library and standard operating procedures to improve consistency and efficiency across projects.
  • Assist business development by drafting technical content for proposals, case studies, white papers and SEO‑optimized web pages related to water consultancy services.
  • Participate in sprint planning and agile-style project management for large multi-disciplinary programs, helping break down technical tasks and estimate effort.
  • Represent the firm at industry conferences, workshops and regulatory meetings to build networks, gather market intelligence and promote expertise in water resources.
  • Develop client training sessions and knowledge transfer materials (toolkits, model runbooks, monitoring manuals) to support long‑term project outcomes and client capacity building.
  • Maintain and update corporate GIS and hydrometric databases to ensure institutional knowledge retention and fast access to historical project data.
