Water Solutions in Pietermaritzburg

Msunduzi Municipality has implemented water shifting and scheduled supply interruptions in recent years to manage reservoir levels and reduce losses, meaning parts of the city are without water on a rota rather than under a formal restriction level. Umgeni-fed restriction notices apply when Midmar drops.

Agricultural and forestry operations abstracting from rivers or boreholes require water use authorisation under the National Water Act, and streamflow reduction activity rules apply to commercial afforestation in this catchment specifically. We size and register systems with those constraints in mind.

Commercial forestry and the timber processing that follows it dominate the Midlands economy, alongside dairy, poultry and vegetable production that need reliable irrigation and washdown water of consistent quality. The city itself carries a heavy concentration of schools, boarding establishments and healthcare facilities — Grey's and Northdale hospitals among them — where a supply interruption is a safety issue rather than an inconvenience. Light manufacturing in the Willowton and Mkondeni industrial areas rounds out demand with process and effluent requirements.

Drilling around Pietermaritzburg means Natal Group sandstone, Ecca shale and Dwyka tillite, with dolerite intrusions providing the most reliable fracture targets. The sandstones give the cleanest water and the most consistent yields; tillite is the least predictable formation in the region and frequently disappoints without a proper survey.

Depths of 70 m to 150 m are typical, with yields of 1 000 to 4 000 litres per hour on a well-sited hole. The hilly Midlands terrain often puts the borehole well below the point of use, so solar-powered pumping into elevated storage is the standard configuration on farms and rural campuses here.
