A properly assessed, planned and engineered solution can save clients anywhere from 25% to 75% on their water usage, ideal in areas where water is a scarce, and often expensive, resource.
WEC Assist provides comprehensive site audits to determine client requirements as well as the feasibility of proposed solutions, ranging from the simple installation of low-flow plumbing systems all the way to grey and black water recovery and recycling to various standards.

WEC Assist’s Reporting Process

Golf Course for Water and Sewage Treatment

Step 1 - Site audits to determine feasibility for water savings

Site audits generally start with an assessment of the client’s utility bill to determine the overall average water consumption and costs for six to twelve months.

Assessments

Africa presents a challenge for water and sewage treatment plants. Lack of basic infrastructure for water and power; unreliable service delivery, lack of maintenance or expansion of aging systems; and communities with limited access to grid supply pose difficulties when designing solutions for water and wastewater treatment. In addition, the logistics and costs involved in delivery and installation further aggravate the situation faced by many communities on the continent.

Site Visits

The next step is a site visit which includes:
Counting the number of toilets, showers, and taps
Locating any leakages
Fittings
Suggestions for replacing point-of-use fittings

Step 2 - Proposing water-optimisation solutions

For boreholes, WEC Assist can handle all assessments, surveying, yield testing, drilling, equipping and licensing on the client’s behalf. A breakdown matrix is utilised to determine which areas of the client’s development use the most water as well as where savings can be made. If necessary, water sampling and analysis of existing water sources, such as boreholes, can be taken and investigations into methods of incorporating them to supplement the primary water supply can be performed.

Step 3 - Providing water-saving solutions

Water usage can be optimised at both the front and back end of the development’s usage chain.

Front-end solutions

Low-flow and flow-reduction fittings for toilets, taps and showers
Harvesting of air conditioner condensation
Drip irrigation systems to reduce irrigation water consumption
Smart metering for real-time water consumption and leak detection

Back-end solutions

At the back end of the water system, WEC Assist can determine the feasibility of recycling and treatment systems for grey and black water to standards from irrigation to potable; and rainwater harvesting including collection, storage and treatment.
