Focus Areas

Water supply Engineering

Under water supply engineering, the firm has for the last 10 years been involved in planning, design and construction supervision of mini and large-scale piped water supply projects for government of Uganda and NGOs. We are able to take on a project from inception, social economic baseline and topographic surveys, feasibility studies, detailed design and construction supervision of water supply schemes including water treatment, water transmission and water distribution.

Our team gained proficiency in use of state-of-the-art water design and modelling software’s such as Epanet 2.0, Water card, AutoCAD Civil 3D and various GIS applications.

Sustainable Biomass Energy production and utilization systems

  • Construction, and commissioning of retort charcoal kilns under ministry of energy and mineral development and UNDP
  • Piloting of Namibian charcoal kiln in Uganda under ministry of energy and mineral development and UNDP
  • Construction of domestic biogas plants under African biogas program ABP under SNV
  • Design, fabrication and training of user of charcoal briquetting equipment
  • Institutional (500 l to 50 l stoves) and domestic energy stoves for

Combined sanitation -Energy waste water treatment systems

We have developed onsite ecological DEWATS with resource recovery element.  Waste water is primarily treated in anaerobic toilets/biodigesters where methane gas is harnessed and additional treatment is achieved by natural UV radiation in soil infiltration trenches or in constructed wetlands as per site/soil conditions.

We have also designed conventional waste stabilization ponds, faucal sludge treatment plants, and associated sewerage pipe network.

Selected Project listing

  1. Feasibility studies and design of alternative sanitation options for Uganda Prisons Service for Luzira, Masaka and Iganga Prisons
  2. Turnkey Design and construction of onsite ecological DEWATS for;
  • More than 10 No. Cotton -on -Foundation schools in central Uganda Lwengo and Rakai districts
  • Onsite sanitation facilities for Namulu Prison in Karamoja
  • Onsite sanitation facilities for Kampala capital city authority schools
  • Onsite sanitation facilities for with biodigester and constructed wetland for Holy cross schools in Jinja
  • Onsite sanitation for school for life schools in Bujuko Mpingi

Building Services Engineering

With over 10 years of working with local and foreign architects and other professionals in the built environment sector, we have built the capacity to take on projects of various magnitude and scope from inception, to design, construction supervision to commissioning and hand over.

From healthcare facilities, educational facilities, office and mixed-use developments, to hotels and outdoor facilities; we design state of the art services tailored to the uniqueness of every project, giving our best to exceed customer expectation.  Our designs are within statutory and regulatory requirements and we work to ensure that projects are implemented within the expected timeframe, budget and minimal life cycle O&M costs as well.

Our specialist is in making a building habitable, for people to live, work in a comfortable space while making the least impact on the environment. We make an effort to promote green architecture and ecological systems
