Commercial and Residential Developments

WEC Assist provides independent assessments, site inspections and audits for clients looking to optimise water usage, reuse and recycling in their commercial and residential developments.

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

Step 1 - Site audits to determine feasibility for water savings

A site audit helps to determine a business case for the implementation of a water saving solution – whether a solution is feasible and if the return on investment is attractive.

Assessments

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.

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

  • Back-up water systems

  • Rainwater harvesting

  • Boreholes

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

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.

    Trickle Filter Sewage Treatment in Zambia - Case Study

    Trickle Filter Sewage Treatment Plant

    WEC Assist provided an assessment for the implementation of a trickle filter sewage treatment system for a residential development in Lusaka, Zambia.

    The development features four apartment blocks, standalone housing units as well as clubhouse, gardens and recreational facilities. The assessment found that the treatment plant, which can process up to 85m3 of sewage per day, will be able to treat a portion of the development’s black water effluent to irrigation water standards using chlorine-based disinfection to reduce impurities. This will significantly reduce the development’s overall water consumption.
